US rate of obesity high but not rising
No "epidemic" after all, it would seem. That many Americans are too fat by someone else's arbitrary definition means nothing other than showing a currently acceptable form of bigotry
Raise a glass of diet soda: The nation's obesity rate appears to have stalled. But the latest numbers still show that more than two-thirds of adults and almost a third of kids are overweight, with no sign of improvement. According to government data from the years 2007-08 published Wednesday, the obesity rate has held steady for about five years, reflecting earlier signs it had stalled after steadily climbing.
Dr. William Dietz, an obesity expert with the Centers for Disease Control and Prevention, cautiously called the results promising. "We're at the corner; we haven't turned the corner," he said.
Not only are the vast majority of adults overweight, 34 percent are obese (roughly 30 or more pounds over a healthy weight); and 17 percent of children are obese. Even the youngest Americans are affected - 10 percent of babies and toddlers are precariously heavy.
The CDC data were contained in two reports published online in the Journal of the American Medical Association. "Even though this finding is certainly good news, the statistics are still staggering," said Dr. J. Michael Gaziano, a contributing editor at the journal.
The new data are based on health surveys involving height and weight measurements of 5,700 adults and 4,000 children, surveys the CDC does every two years. The results in adults, showing 68 percent are too heavy, have been virtually the same in the last three surveys.
In most age groups, black adults had the highest rates of obesity, followed by Mexican-Americans and whites. Among children and young people ages 2 to 19, 32 percent were too heavy - a rate that was mostly unchanged. But disturbingly, most obese kids were extremely obese. And the percentage of extremely obese boys ages 6 to 19 has steadily increased, to 15 percent from about 9 percent in 1999-2000.
CDC researcher and study author Cynthia Ogden said it was disappointing to see no decline and troubling that the heaviest boys seem to be getting even heavier. The study didn't examine the causes, but Ogden cited the usual reasons - soft drinks, video games and inactivity - as possible explanations. "We shouldn't be complacent. We still have a problem," Ogden said.
Gaziano, a cardiologist at Boston's Veterans Affairs Hospital and Brigham and Women's Hospital, said getting the nation to turn the corner and reduce obesity requires changing many unhealthful behaviors, and getting restaurants, schools, food manufacturers and communities to support the fight. That's starting to happen, from efforts to pull soda from school vending machines to campaigns by groups like the NFL to encourage physical activity, Gaziano said.

Breast cancer chemotherapy can be cut to six weeks -- in mice
A new drug course could beat breast cancer in six weeks and eliminate the need for months of chemotherapy. Scientists have found that a combination of drugs regularly given to breast cancer patients destroyed tumours in a shorter period of time. Researchers at the University of Sheffield found a combination of treatments given over a period of six weeks was as effective as six months of treatment.
Around 45,000 women in Britain each year are diagnosed with breast cancer. Less exposure to chemotherapy would reduce the risk of side-effects, such as hair loss, nausea and, in some cases, permanent infertility.
The research team had already proven the effectiveness of using doxorubicin, a chemotherapy drug commonly given to stop tumour growth, and zoledronic acid, a well-tolerated treatment given to protect bone in advanced breast cancer. Senior lecturer Dr Ingunn Holen and her team treated a group of mice with the combination every week for six months and another group for six weeks.
The International Journal of Cancer said that in both groups tumours shrank from their original size and became barely detectable. Dr Holen said: 'These findings are very promising. Clinical studies in patients are now needed.'

Isn't the aim of the lunchbox to make sure that children eat?
British mother Anna Maxted on the research that shows that most parents fail to comply with nutritional standards when they make their children's lunchboxes
Every morning I sling the same four items into the seven-year old's lunchbox and feel like a rotten mother. From Monday to Friday throughout term, my son eats the same boring, nutritionally suspect lunch: Marmite sandwich, yoghurt drink, carton of juice, Shape bar.
I am in bad company, as it turns out that ninety nine per cent of British mothers are equally slack in regard to their darlings' diet. Research at Leeds University – out this week in an associate publication of the British Medical Journal – finds that if nutritional standards were applied to packed lunches, only one per cent would comply. Of the 1,300 seven and eight-year olds surveyed, more than a quarter had a lunchbox containing sweets, crisps and a sugary drink. Only one in ten had a portion of vegetables.
The nanny state is, of course, alert to the fact that we slipshod parents will feed our kids any cheap fatty rubbish. The School Food Trust (slogan: Eat Better, Do Better), established by the Department of Education and Skills in 2005, actually provides "menus to help parents" who are seemingly incapable of filling a lunchbox without adding Haribos. This term, my sons' school newsletter issues a stern reminder that "children should not bring sweets or chocolates in their packed lunch".
The truth: we slapdash mothers have begged, then forced, our children to trot to school with a flask of home-made broccoli soup, tomatoes, a banana, an organic flapjack, a peanut butter sandwich on granary bread, dried chopped apricots and a peach smoothie.
The following morning, we retrieve the lunchboxes from the hallway floor to find: a bruised yet untouched banana, squashed tomatoes, spat-out apricot. The soup flask has been opened and promptly shut, but not fully, and has leaked. The flapjack, lovingly baked at midnight, is crumbled into a thousand pieces. Even the peanut butter sandwich has failed. "We're not allowed nuts," the seven-year old informs me crossly. "I got told off."
The no-nut policy also rules out the organic Bombay mix I discovered while frantically scouring the health food store for non-harmful, government approved ingredients. I don't want to give my seven-year old a Shape bar (7g of sugars in 21g), but the Granola bar was rejected by the food police on no-nut grounds too – "Mrs Kent said I had to eat it at home time." Furiously, I checked the packet. The Granola contains "traces" of almond and hazelnut. The Shape bar only contains fructose, dextrose, sugar, sorbitol and glycerol, so it's permitted.
I surrendered to the Cheese String – but that fad ran its course. Organic yoghurt tubes are rejected as "babyish". The five-year-old is just as picky. The only way I can sneak fruit into his lunchbox is via the extortionate Innocent "Squeezie" – £2.19 for a few squirts of mango puree – and an Ella's Kitchen "squished organic fruit" pouch. If I chance a satsuma, it remains uneaten, desperate fingernail marks in its peel telling a sad tale of failure and frustration.
It was all so different, of course, when the first child started reception. We parents were half-crazed with optimism. One Japanese mother I know would rise at dawn to make fresh sushi. Another friend had her four-year-old schlep in daily with half an avocado plus bottle of vinegarette. This regime lasts until the child claps eyes on a Hula-Hoop.
Last week, in desperation, I scanned the online list of lunchbox ideas by children's cook Annabel Karmel, and wanted to cry; Spanish omelette? Chicken Caesar salad? Sign on back saying "kick me"? And before anyone mentions hummus, know this: unless you want your children to be bullied, don't send them to school with food that smells.
Dietician Dr Sarah Schenker, of the British Nutrition Foundation, knows, despite the alleged evidence, that most parents yearn to trick their angels into eating the nutritionally perfect lunch – even pouring Cornflakes into a plastic bag and trying to pass them off as crisps – but that we inevitably have to compromise. "You can make a packed lunch super healthy but if it's coming back untouched, that is more serious than if something has been eaten that is not your ideal choice," she says.
This morning, staring dolefully at its meagre contents, I ask Oscar, "is there anything I can add to your lunchbox?" and he replies no, thank you, that he is "the fastest" at eating his lunch.
The government is perhaps unaware that when you are seven, it is less important to be full than to be finished. They may also be ignorant of the fact that when our poor, malnourished children return home, they gorge on grapes, carrots, cucumber and apples all evening, without a squeak of protest.

Farmed windpipe transplanted in crash victim
A very interesting new procedure

A WOMAN whose windpipe was crushed in a car crash has had it replaced with an implant that was farmed in her arm. For more than 25 years Linda De Croock lived with the constant pain of having two metal stents propping open her windpipe, Sky News reports. That was until the Belgian found a doctor, Pierre Delaere, on the internet who was willing to try something new. "I had always wondered, so many things are possible, why not a new windpipe?" Ms De Crook said.
Dr Delaere and his colleagues, who had performed similar procedures on a smaller scale for cancer patients, agreed to carry out the operation. Once the doctors had a suitable donor windpipe they wrapped it in Ms De Croock's own tissue and implanted it into her lower left arm. There they connected it to a large artery to re-establish the blood flow.
Ms De Croock said having a windpipe in her arm felt strange and uncomfortable. "It was packed in with gauze and my whole arm was in plaster." About 10 months later, when enough tissue had grown around it, the windpipe was transferred to its proper place. Dr Delaere was delighted with the result. "This is a major step forward for trachea transplantation," he said.
Ms De Croock said the operation had transformed her life. "Life before my transplant was becoming less livable all the time, with continual pain and jabbing and pricking in my throat and windpipe," she explained, adding that she no longer even needs to take anti-rejection drugs.
The way doctors at Belgium's University Hospital trained her body to accept donor tissue could yield new methods of growing or nurturing organs within patients, experts say.
Patrick Warnke, a tissue-engineering expert at Bond University in Australia, said it was the first time a donor organ as large as the trachea was nurtured inside the recipient's own body before being transplanted. "This shows us that we may one day be able to use patients' own bodies as bioreactors to grow their own tissue," he said.

Statins may cut risk of cataracts by 40%
Groan! More nonsense. OF COURSE people who took statins were healthier in general. Statins have such severe side-effects that you HAVE to be robust to stay on them
Statins could cut the chances of developing cataracts by nearly 40 per cent, research shows. Men aged between 45 and 54 who took the cholesterol-lowering pills virtually every day reduced their risk of cataracts later in life by 38 per cent compared with those who took them rarely, according to a study in the journal Annals of Epidemiology. In women of the same age, the risk was reduced by about 18 per cent.
But those aged 75 or more when they started on statins saw very little reduction in risk. Scientists who carried out the study of 180,000 people at Tel Aviv University in Israel said there was evidence that statins protect the eyes by reducing inflammation and protecting cells against a harmful process called oxidation.
About 200,000 people are year are treated for cataracts in Britain, a figure that is expected to rise significantly due to the ageing population.

Breastfed babies less aggressive -- but why?
The usual abuse of correlations. How do we know that mothers who breastfeed are not themselves less aggressive and simply pass on their temperament genetically? Maybe it helps to be a bit bovine to breastfeed
BABIES breastfed for six months or longer are less likely to be aggressive, anxious or depressed during childhood and into adolescence, a study has found. But more research is needed for scientists to understand why.
The study by Perth's Telethon Institute for Child Health Research tracked children born to more than 2300 mothers between 1989 and 1992, assessing their mental health at regular intervals from age two to 14. Eleven per cent were never breastfed, 38 per cent received breast milk for less than six months and just over half were breastfed for six months or more.
Nutritional epidemiologist Wendy Oddy, the lead researcher, speculated the biological components of breast milk might be involved in improved mental health outcomes. "There's a mass of literature showing the benefits of human milk over formula," she said.
But the ability of breastfeeding to enhance the mother-baby bond may also play a role. "It's most likely a combination," Professor Oddy said. "We're not able to say from this study whether it was the specific nutrients in breast milk, the bonding aspects, or both."

For healthy mental aging, brain games can fill in for schooling?
More epidemiological stupidity -- confusing cause and effect
It's well documented that people lacking college degrees are more likely to develop memory problems or even Alzheimer's disease later in life. [Which means what? That people with poor memories to start with cannot handle college?]
But people can significantly compensate for poorer education by engaging often in mental exercises such as word games, puzzles, reading, and lectures, a large national study has found. "Among individuals with low education, those who engaged in reading, writing, attending lectures, doing word games or puzzles once or week [i.e. those who were naturally smart to start with] or more had memory scores similar to people with more education," said psychologist Margie Lachman of Brandeis University in Waltham, Mass., lead author of the study published in the American Journal of Geriatric Psychiatry.
"The lifelong benefits of higher education for memory in later life are quite impressive, but we do not clearly understand how and why these effects last so long," she noted. It could be because higher education promotes lifelong interest in cognitive endeavors, she added. By contrast, people with less education may engage less often in mental exercises that help keep the memory agile.
The study assessed 3,343 men and women between the ages of 32 and 84 with an average age of 56. Almost 40 percent of the participants had at least a four-year college degree. Lachman and colleagues evaluated how the participants performed in two cognitive areas, verbal memory and executive functionbrain processes involved in planning, abstract thinking and cognitive flexibility. Participants were given a battery of tests, including tests of verbal fluency, word recall, and backward counting.
"The findings are promising because they suggest there may be ways to level the playing field for those with lower educational achievement, and protect those at greatest risk for memory declines," said Lachman. "Although we can not rule out the possibility that those who have better memories are the ones who take on more activities, the evidence is consistent with cognitive plasticity, and suggests some degree of personal control over cognitive functioning in adulthood by adopting an intellectuly active lifestyle."

NYC: Restaurant chefs boiling over Bloomberg’s latest really stupid idea
Mayor Bloomberg yesterday defended his latest nanny initiative — a controversial crackdown on salt — by comparing the simple seasoning to killer asbestos in the classroom. "If we know there's asbestos in a school room what do you expect us to do?" Bloomberg shot back at reporters questioning his new initiative. "Say it's not our business? I don't think so. The same thing is true with food and smoking and a lot of things.
"Salt and asbestos, clearly both are bad for you," Bloomberg continued. "Modern medicine thinks you shouldn't be smoking if you want to live longer. Modern medicine thinks you shouldn't be eating salt, or sodium." [There is no such thing as a monolithic "modern medicine" -- only a range of ideas]
Bloomberg is pushing a plan to cut the amount of salt in packaged and restaurant foods by 25 percent over the next five years. He says the initiative is voluntary.
Never mind that salt has important properties that preserve and stabilize food, and its sodium ions help maintain the fluid in human blood cells. Forget that the body does not manufacture its own sodium ions so there has to be some salt in everyone's diet.
Restaurant owners have a less scientific reason for disliking the crackdown: salt makes food taste good. Some of the city's top chefs and restaurant owners yesterday had a spicy message for City Hall: Simmer down and stay out of our kitchens. "I'm all for trying to make New Yorkers healthier people," said acclaimed chef Ed Brown, owner of the restaurant eighty one on the Upper West Side. "But when it comes to him telling me how much salt to put in food, I have a problem with it."
Noted chef David Chang, owner of the Momofuku Noodle Bar, said cooks have been using salt with food almost as long as they have been using fire. "You need salt to draw flavor out of food," Chang said. "It's a skill that you teach cooks. For that to be regulated by the government is just stupid and foolish."
Too much sodium contributes to high blood pressure, which can cause heart attacks and stroke, health officials say.

The golden oldie gene: One in five has age-defying 'centenarian gene' that greatly increases odds of living to 100
What! It's not a diet low in fat and salt that does it?? How pesky! Seriously, though, this is a small and limited study and is mostly of interest for opening up a line of inquiry
In the genetic lottery of life expectancy, you might think 100 is a pretty lucky number. Now it's just got luckier. Scientists have discovered that a gene already known to treble your odds of living to 100 may also ward off Alzheimer's disease. One in five of us is dealt this genetic hand that promises to extend our lives without the loss of mental agility.
The gene is the first to be identified that actually cuts the odds of Alzheimer's disease rather than raising them. Its discovery could pave the way for new drug treatments to combat the devastating illness. More than 700,000 Britons have Alzheimer's disease and other forms of dementia and the number of cases is expected to double within a generation. There is no cure and existing drugs, which raise levels of key brain chemicals, do not work for everyone and their effects wear off over time.
Researchers from the Albert Einstein College of Medicine in New York tracked the health of more than 500 elderly men and women for four-and-a-half years. All were free of dementia at the start of the study but 40 had developed it by the end. Blood samples showed that the CETP gene, already known to treble-the odds of living to 100, also cut the odds of dementia by 70 per cent.
Genes come in pairs - and it was those with two copies of the 'centenarian' version who benefited, both from the added longevity and the Alzheimer's protection. They also suffered less age-related memory decline, the Journal of the American Medical Association reported.
Researcher Dr Amy Sanders said: 'We found that people with two copies of the longevity variant had slower memory decline and lower risk for developing dementia and Alzheimer's disease. More specifically-those who carried two copies of the favourable variant had a 70 per cent reduction in their risk for developing Alzheimer's disease compared with those who didn't.' Around one in five of those studied had the required pair of ' centenarian' genes.
Researcher Dr Richard Lipton said: 'Most work on the genetics of Alzheimer's disease has focused on factors that increase the danger. 'We reversed this approach and instead focused on a genetic factor that protects against age-related illness, including both memory decline and Alzheimer's disease.' The CETP gene affects levels of artery-clogging cholesterol in the body. The 'centenarian' version raises levels of 'good' cholesterol, cutting the risk of heart disease and, it appears, dementia. A pill that acts in same way could help people live longer, healthier lives.
Separate research has suggested that drugs widely used to treat high blood pressure may also be of use in dementia. Those taking ACE inhibitor and angiotensin receptor blocker pills had half the risk of the disease, according to a report in the British Medical Journal.
The global population of centenarians is expected to rise from 340,000 today to almost 6 million by the middle of the century. The UK share will rise from just over 10,000 today to 280,000.

Good show: Only one in 100 British pupils' packed lunches conform to food faddist dreams
The drive to improve nutrition in schools is failing to reach the country’s children, with only one in 100 packed lunches meeting basic dietary standards, research suggests. High-profile school campaigns by the Government and Jamie Oliver to improve children’s packed lunches have made little impact, with crisps, sweets, and sugary drinks taking precedence over vegetables, fruit, and milk-based products.
Research published in the Journal of Epidemiology and Community Health suggests that only 1 per cent of primary school children’s packed lunches meet the nutritional standards set for school meals in England. One in three children was given a sandwich with a low-protein filling, and only one in ten children had sandwiches containing vegetables [A sandwich containing vegetables! What a horrible thought!]. A further one in ten was given a separate portion of vegetables. The foodstuff least likely to be eaten when provided was fruit, while confectionery was most commonly consumed.
About half of British schoolchildren eat a packed lunch brought from home — equating to 5.5 billion packed lunches eaten every year.
New standards setting out the required healthy food groups for prepared meals came into force for all local authority schools in England in 2006, prompted by concerns that school lunches were not providing sufficiently healthy food choices. These specify that school lunches must contain protein rich and low-fat starchy foods, vegetables, fruit and dairy products. Meals cannot include sweets (confectionery), savoury snacks or artificially sweetened drinks. These were followed in 2008 by further government standards on the energy, fat, salt, vitamin and nutrient content for school meals.
All the children took a packed lunch to school on at least one day of the week, and almost nine out of ten ate a packed lunch every day. The type and quantity of foods for each child’s lunch box were recorded and weighed before and after lunch on one day and compared with the Government’s school meal standards. Permitted savoury or sweet foods, vegetables, and permitted drinks (natural juice, milk, pure water) were the least likely to be provided. Sandwiches, sweets, savoury snacks and artificially sweetened drinks were the most common items.
More than one in four children had a packed lunch containing sweets, savoury snacks, and sugary drinks; a further four out of ten had sweets and snacks, but no sugary drink. Fewer than one in ten had none of these foodstuffs in their lunchbox.
The research team, from the Centre for Epidemiology and Biostatistics at the University of Leeds, collected information on the packed lunch content for just under 1,300 children between the ages of 8 and 9. It focused on 89 primary schools across Britain — 76 in England, four in Scotland, six in Wales and three in Northern Ireland.

Extra hour of TV a day can kill, say medical witch doctors
Lord love us! More epidemiological "wisdom". They found, unsuprisingly, that people in poor health watched slightly more TV but in their wisdom from on high they interpreted it the other way around! It must be wonderful to have God-given insight that dispenses with the need for evidence! I personally watch TV about once a year but have no time for fraudulent scares. Scares that simply lead to needlessly upset children are particularly obnoxious
VIDEO killed the radio star, according to the famous Buggles song, but new research suggests television is killing the rest of us too. An additional hour in front of the box each day increases the risk of dying from cardiovascular disease by 18 per cent, according to Australian research published in the Journal of the American Heart Association. Each extra hour increases by 11 per cent the overall likelihood of dying from all causes, including cancer.
"The human body was designed to move, not sit for extended periods of time," the study's lead author, David Dunstan, said. "But technological, social and economic changes mean that people don't move their muscles as much as they used to. "For many people, on a daily basis they simply shift from one chair to another."
Prof Dunstan, from the Baker IDI Heart and Diabetes Institute in Melbourne, said sitting for long periods was bad for blood sugar and fats - even if you were healthy. The link between television viewing and increased mortality held true regardless of other risk factors such as smoking, poor diet, high cholesterol and obesity.
The average Australian watched three hours of television every day. The researchers monitored the viewing habits of 8800 adults over six years before publishing the alarming results. They found someone who watched four hours of TV each day had an 80 per cent higher risk of death from heart disease compared to someone who watched less than two hours.
They were 46 per cent more likely to die from all causes. Prof Dunstan said the findings suggested any prolonged sedentary behaviour, such as sitting at a desk or computer for work, could be risky. The answer? "Move more, more often." "In addition to doing regular exercise, avoid sitting for prolonged periods," he said. "Too much sitting is bad for health."

Broccoli really is good for you
Even though George Bush senior refuses to eat it! But in the study below it was shown to be helpful only if you have stomach ulcers and if you eat a lot of salt. Unclear how important the finding is. The action seems to be bacteriocidal but existing antibiotics are also effective against the bug that causes stomach ulcers. Also unclear is generalizability. The sample is small and the Japanese are unusually prone to stomach ulcers, possibly because they eat very large amounts of salt (in soy sauce, for instance)
Dietary Sulforaphane-Rich Broccoli Sprouts Reduce Colonization and Attenuate Gastritis in Helicobacter pylori–Infected Mice and Humans
By Akinori Yanaka1 et al.
Abstract
The isothiocyanate sulforaphane [SF; 1-isothiocyanato-4(R)-methylsulfinylbutane] is abundant in broccoli sprouts in the form of its glucosinolate precursor (glucoraphanin). SF is powerfully bactericidal against Helicobacter pylori infections, which are strongly associated with the worldwide pandemic of gastric cancer. Oral treatment with SF-rich broccoli sprouts of C57BL/6 female mice infected with H. pylori Sydney strain 1 and maintained on a high-salt (7.5% NaCl) diet reduced gastric bacterial colonization, attenuated mucosal expression of tumor necrosis factor-{alpha} and interleukin-1β, mitigated corpus inflammation, and prevented expression of high salt-induced gastric corpus atrophy. This therapeutic effect was not observed in mice in which the nrf2 gene was deleted, strongly implicating the important role of Nrf2-dependent antioxidant and anti-inflammatory proteins in SF-dependent protection. Forty-eight H. pylori–infected patients were randomly assigned to feeding of broccoli sprouts (70 g/d; containing 420 µmol of SF precursor) for 8 weeks or to consumption of an equal weight of alfalfa sprouts (not containing SF) as placebo. Intervention with broccoli sprouts, but not with placebo, decreased the levels of urease measured by the urea breath test and H. pylori stool antigen (both biomarkers of H. pylori colonization) and serum pepsinogens I and II (biomarkers of gastric inflammation). Values recovered to their original levels 2 months after treatment was discontinued. Daily intake of sulforaphane-rich broccoli sprouts for 2 months reduces H. pylori colonization in mice and improves the sequelae of infection in infected mice and in humans. This treatment seems to enhance chemoprotection of the gastric mucosa against H. pylori–induced oxidative stress.

Loony bisphenol phobia still not dead
Scare claim: Bisphenol A in plastic bottles 'harms babies'. Like most things, BPA can be harmful. So can common salt. The toxicity is in the dose. Any release of BPA from baby bottles would be at the rate of something like one molecule at a time and there is neither probability nor evidence of toxicity at that rate. And we all in fact have BPA in us with no apparent ill effects. Anti-business alarmists have been trying for years to demonize this stuff. There is some evidence that industrial exposure to BPA is harmful, but that shows only that many things (even water) can be harmful if you ingest huge amounts of them. It does not follow that something ingested in huge amounts is harmful in tiny amounts. The opposite can be true. Check hormesis. The report below is from Australia but there is an article debunking similar scares in the USA here
FEDERAL health authorities are to come under increasing pressure to ban the sale of baby bottles made with Bisphenol A (BPA) after new evidence it can harm health. Widely used in plastics, particularly food and drink containers, BPA leaches when heated, leading it to being withdrawn elsewhere in the world.
It had been thought the chemical posed no real health threat in tiny doses, but scientists in the UK now say they have found compelling evidence the chemical is linked to breast cancer and sex hormone imbalances, and is particularly linked to adverse health risks to babies. [Reference?]
A team of European scientists will this month begin a campaign to lobby their governments to remove baby bottles containing BPA from shelves. Last year, baby bottle manufacturers in the US removed BPA from their products, reacting to widespread consumer concern.
Federal Health Minister Nicola Roxon said yesterday it was the responsibility of the Therapeutic Goods Administration to declare BPA unsafe or otherwise. The TGA in turn said it was an issue for the federal Health Department, which passed the buck and declared it an issue for Food Standards Australia New Zealand (FSANZ). FSANZ confirmed it had no regulatory authority over baby bottles and had never commissioned its own study on the issue, though it was monitoring the overseas BPA debate and that the most up-to-date science indicated there was a maximum daily safe limit.
Queensland-based anti-BPA campaigner Nadia Duensing has written to the Health Minister in light of the new research. "I can't understand why the Australian Government is not following the lead from elsewhere," she said. Ms Duensing, a grandmother, was so concerned about the possible health effects of BPA she launched a website campaigning against the chemical and selling BPA-free baby products.
Some of the biggest-selling baby bottle brands in Australia still sell bottles with BPA in them, including Avent, which is owned by Philips. A Philips spokeswoman said yesterday that the company was acting responsibly and within guidelines set out by FSANZ, which concluded that levels of exposure (in infants) were very low and did not pose a significant health risk.
Ms Duensing said most mums did not realise the differences between different types of plastic bottles. "Mothers go into a shop and see a polycarbonate bottle for about $10 and a BPA-free one for $18 and they don't know the difference – they just get the cheaper one thinking plastic is plastic," she said.

Having sex twice a week can reduce heart disease in men by half, study reveals
The usual epidemiological nonsense that "intuits" the direction of the cause. The findings show shows that healthier men have more sex, which is no surprise for a variety of reasons
Men don't usually need an excuse to indulge in a spot of passion. But if they did, here's one that sounds more convincing than most - making love is good for their hearts, it seems. Men who have sex at least twice a week can almost halve their risk of heart disease, according to research. Those who make love regularly are apparently up to 45 per cent less likely to develop life-threatening heart conditions than men whose sexual encounters are limited to just once a month or less.
The study, of more than 1,000 men, shows sex appears to have a protective effect on the male heart but did not examine whether women benefit too. Now the American researchers are calling for doctors to 'screen' men for sexual activity when assessing their risk of heart disease. The benefits of love-making could be due to both the physical and emotional effects on the body, they said. 'Men with the desire for frequent sexual activity and who are able to engage in it are likely to be healthier,' the scientists told the American Journal of Cardiology.
'But sex in some forms has a physical activity component that might directly serve to protect cardiovascular health. 'Also, men who have frequent sex might be more likely to be in a supportive intimate relationship. 'This might improve health through stress reduction and social support.'
The scientists at the New England Research Institute, based in Massachusetts, spent 16 years tracking the sexual activity of men aged between 40 and 70. Each of the volunteers was quizzed at regular intervals about how often they had sex. They were then checked for signs of heart disease. Other risk factors, such as age, weight, blood pressure and cholesterol levels, were also taken into account.
Although sex has long been regarded as good for both physical and mental health, there has been little scientific evidence of benefits on major illnesses such as heart disease until now. An earlier study at the National Cancer Institute in the U.S. showed men who ejaculated through sex or masturbation at least five times a week are much less likely to develop prostate cancer.
And having sex once or twice a week during the winter months can boost the immune system and reduce the chances of catching colds and flu, according to scientists at Wilkes University, Pennsylvania. It boosts levels of a chemical called immunoglobulin A 6, which binds to organisms that invade the body and then activates the immune system to destroy them.
Regular intercourse can even boost a woman's sense of smell by triggering the release of a hormone called prolactin, researchers at Canada's Calgary University found. This may be a mechanism to help mothers bond with their new babies.
Every year, around 270,000 people in Britain suffer a heart attack, and coronary disease remains the nation's biggest killer.

IVF babies ‘risk major diseases’
Another chicken and egg finding. IVF babies have SLIGHTLY higher incidence of problems but is that due to the method of their conception or prior defects in their parents? The latter seems by far the most probable
Scientists have discovered that the DNA of babies conceived through IVF differs from that of other children, putting them at greater risk of diseases such as diabetes and obesity later in life. The new research could explain why IVF babies tend to be at higher risk of low birth weight, defects and rare metabolic disorders.
The changes are not in the genes themselves but in the mechanism that switches them on and off, the study of which is known as epigenetics. “These epigenetic differences have the potential to affect embyronic development and foetal growth, as well as influencing long-term patterns of gene expression associated with increased risk of many human diseases,” said Professor Carmen Sapienza, a geneticist at Temple University in Philadelphia, who jointly led the research. There is a possibility that such changes could be transmitted to the children of IVF babies, meaning they could spread through the human gene pool.
In their findings, published in the Human Molecular Genetics journal, Sapienza and his colleagues took blood samples from the placenta and umbilical cords of 10 IVF children and 13 children who were naturally conceived. They studied the DNA of cells taken from the blood to see if there were differences in the level of methylation. This is the process by which molecules known as methyl groups are attached to genes to shut them down when they are not needed.
The results showed that the level of methylation in the cells taken from IVF babies was significantly lower — implying that some genes were becoming active at the wrong times. “We have shown that in vitro conception is associated with differences in gene methylation and that some of these differences may affect gene expression,” said Sapienza.
The findings could have serious implications for the booming industry in assisted reproduction. About 40,000 women a year undergo IVF in Britain, often paying tens of thousands of pounds in the hope of conceiving. Some 15,000 IVF babies are born each year — about 2% of all births — so they are a significant component of the UK gene pool.
Sapienza, however, was unable to ascertain the actual cause of the epigenetic changes he observed. One possibility is that couples who are infertile may have naturally higher levels of epigenetic changes than the rest of the population, perhaps explaining the cause of their infertility.

Brain scan could diagnose autism early
This is highly dubious. Mental speed is also related to IQ
Children could be screened for autism at an early age after scientists developed a way to recognise the condition using brain scans. Diagnosis of autism has always been difficult and often the condition is recognised at too late a stage for treatment to have a major effect.
But now researchers believe they have discovered a potential way of spotting the disorder in early infancy by scanning the brainwaves. They have discovered that children with autism spectrum disorders (ASD) recognise sound a fraction of a second slower (11 milliseconds) than unaffected children. This is significant because it can be picked up by a brain scan and so become a standardised way to diagnose the condition.
Dr Timothy Roberts, the lead researcher at Children's Hospital in Philadelphia, said the scan could become the first "standard tool" for recognising autism. His tests showed that the delay is present in children with autism aged 10 and if further tests prove the same is true in much younger children then it could lead to widespread screening. "An 11-millisecond delay is brief, but it means, for instance, that a child with ASD, on hearing the word ‘elephant’ is still processing the ‘el’ sound while other children have moved on," he said. "The delays may cascade as a conversation progresses, and the child may lag behind typically developing peers.”
It is estimated that around one in 100 children between five-years-old and nine-years-old have autism, meaning there are around 500,000 in Britain. The condition covers a wide spectrum of disorders with cases ranging from relatively mild problems with social interaction to more severe difficulties in behaviour such as not speaking, copying, rigid routines and social isolation.
While the causes of the condition remain a mystery, early and intensive treatment is known to help alleviate the symptoms. The problem is that diagnosis can be difficult and often relies on waiting for the symptoms to develop by which time a lot of damage has been done.
In the current study, published in the journal Autism Research, Dr Roberts used a magnetoencephalography (MEG), a scanner that detects magnetic fields in the brain. Using a helmet that surrounds the child’s head, the team presents a series of recorded beeps, vowels and sentences. As the child’s brain responds to each sound, non-invasive detectors in the MEG machine analyse the brain’s changing magnetic fields.
The researchers compared 25 children with ASDs with an average age of 10 years to 17 age-matched typically developing children. The children with ASDs had an average delay of 11 milliseconds (about 1/100 of a second) in their brain responses to sounds, compared to the control children. Among the group with ASDs, the delays were similar, whether or not the children had language impairments.
The system may be able to diagnose ASDs as early as infancy, permitting possible earlier intervention with treatments. They also may be able to differentiate types of ASDs such as classic autism and Asperger’s syndrome in individual patients.
Autistic children who are taught intensively at home at the age of three can double their IQ within two years, it is believed. Dr. Gina Gómez de la Cuesta, Action Research Leader at the National Autistic Society, said: “The initial findings of this small scale study are useful. “Many children still have to wait years for a diagnosis and so without the right support this can have a profound effect on them and their families. "Early diagnosis and intervention can make a huge difference to peoples' lives if the right environment, education and services can be put in place as soon as possible."

The Norwegian approach to superbugs
I suspect that this does not tell the whole story. What happens when someone gets a serious infection that only an advanced antibiotic can stop? This sounds more like cost control to me. Nobody disputes that antibiotics are overused but they do have their place
“Aker University Hospital is a dingy place to heal. The floors are streaked and scratched. A light layer of dust coats the blood pressure monitors. A faint stench of urine and bleach wafts from a pile of soiled bedsheets dropped in a corner.” This is how an Associated Press story, published in the New York Times last week, begins. The next sentence comes as a surprise:
“Look closer, however, at a microscopic level, and this place is pristine. There is no sign of a dangerous and contagious staph infection that killed tens of thousands of patients in the most sophisticated hospital of Europe, North America and Asia this year, soaring virtually unchecked. “The reason: Norwegians stopped taking so many drugs.
“Twenty-five years ago, Norwegians were also losing their lives to this bacteria. But Norway's public health system fought back with an aggressive program that made it the most infection-free country in the world. A key part of that program was cutting back severely on the use of antibiotics.
“Now a spate of new studies from around the world prove that Norway's model can be replicated with extraordinary success, and public health experts are saying these deaths--19,000 in the U.S. each year alone, more than from AIDS--are unnecessary.
“‘It's a very sad situation that in some places so many are dying from this, because we have shown here in Norway that Methicillin-resistant Staphylococcus aureus (MRSA) can be controlled, and with not too much effort’,said Jan Hendrik-Binder, Oslo's MRSA medical adviser. ‘But you have to take it seriously, you have to give it attention, and you must not give up. . . . '
“Norway's model is surprisingly straightforward. “-- Norwegian doctors prescribe fewer antibiotics than any other country, so people do not have a chance to develop resistance to them.” Many antibiotics simply are not available.
When Dr. John Birger Haug opens the dispensary at Aker hospital, one sees “a small room lined with boxes of pills, bottles of syrups and tubes of ointment. What's here? Medicines considered obsolete in many developed countries. What's not? Some of the newest, most expensive antibiotics, which aren't even registered for use in Norway, ‘because if we have them here, doctors will use them,’ he says. . . .
“Norway responded swiftly to initial MRSA outbreaks in the 1980s by cutting antibiotic use. Thus while they got ahead of the infection, the rest of the world fell behind. “In Norway, MRSA has accounted for less than 1 percent of staph infections for years. That compares to 80 percent in Japan, the world leader in MRSA; 44 percent in Israel; and 38 percent in Greece. “In the U.S., cases have soared and MRSA cost $6 billion last year. Rates have gone up from 2 percent in 1974 to 63 percent in 2004”
Could the Norwegian solution work here? Yes—if patient safety came first in U.S. hospitals. Why am I so sure?
“In 2001, the CDC approached a Veterans Affairs hospital in Pittsburgh about conducting a small test program. It started in one unit, and within four years, the entire hospital was screening everyone who came through the door for MRSA. The result: an 80 percent decrease in MRSA infections. The program has now been expanded to all 153 VA hospitals, resulting in a 50 percent drop in MRSA bloodstream infections, said Dr. Robert Muder, chief of infectious diseases at the VA Pittsburgh Healthcare System.
“It’s kind of a no-brainer,’” he said. ‘You save people pain, you save people the work of taking care of them, you save money, you save lives and you can export what you learn to other hospital-acquired infections.’”...
Although it may seem a “no-brainer,’ the Norway solution has not been widely adopted in rest of the U.S. health care system. AP reports: “Dr. John Jernigan at the U.S. Centers for Disease Control and Prevention said they incorporate some of Norway's solutions in varying degrees, and his agency ‘requires hospitals to move the needle, to show improvement, and if they don't show improvement they need to do more.’"
And if they don't? "Nobody is accountable to our recommendations,’" Jernigan told AP, "but I assume hospitals and institutions are interested in doing the right thing.’"

Big talker finally given the boot
This couldn't happen to a nicer fraud. She is constantly shooting her mouth off and pretending to know what she does not know. She claims that TV and computers are harmful despite evidence pointing the other way. In a polite British way, her colleagues have finally had enough of her. The fact that she was a financial bungler as well as a scientific fraud would seem to have been the last straw. The financial bungling is a bit of a surprise in a smart Jewish girl but her lack of scientific depth is too. Her main talent seems to be for self-promotion and that can easily wear thin in Britain. Background on her here
Baroness Greenfield has lost her job as the director of one of Britain’s oldest and most venerable scientific institutions, The Times has learnt. The neuroscientist and peer, who is one of Britain’s most prominent female scientists, was served with redundancy papers yesterday by the Royal Institution of Great Britain (RI), where she was director, the organisation confirmed last night.
Her position at the head of the institution where Michael Faraday and Sir Humphrey Davy once worked is to be abolished after a review of its managment structure and a financial crisis that could threaten its survival. The RI’s trustees decided that the position of a full-time director was no longer affordable in the light of funding problems that has left it more than £3 million in the red. Its chief executive, Chris Rofe, will now head the organisation.
Lady Greenfield, who could not be contacted for comment, is understood to have consulted employment lawyers about the decision, which she is considering challenging.
When contacted by The Times last night, Mr Rofe confirmed that Lady Greenfield was being made redundant. He said: “The trustees of the Royal Institution of Great Britain have completed the first stage of a governance review and as a consequence have concluded that the requirement for the functions of the role of director as currently defined has ceased to exist. We are therefore sad to announce that Baroness Susan Greenfield left the RI on 8th January 2010.
“Baroness Greenfield has played a leading role, not only in the development of the RI, but also in the wider scientific community through her work in popularising science. Baroness Greenfield leaves with our thanks and we wish her all the very best in her future endeavours. “Over the coming months the organisation will focus on strengthening its finances, fundraising, and addressing the organisational governance to ensure the Ri continues to deliver its many, diverse and renowned activities in scientific research, education and public engagement.”
Lady Greenfield’s departure follows heavy losses incurred by the RI during a £22 million refurbishment project she masterminded, which left it so short of funds that its auditors have raised questions about its ability to continue operating. In its most recent submission to the Charity Commission, its auditors said that its future viability would depend on rapid improvements in its finances that could not be guaranteed. “If the charity is to continue as a going concern, the financial projections for the three years ending 30 September, 2011, need to be met,” the audit report said. “There is a significant uncertainty as to whether these projections will be achieved.”
RI sources told The Times that its trustees considered that its precarious finances meant the organisation could no longer afford to employ a senior scientist as a full-time director. Some are also understood to have doubted whether it could improve its financial position under Lady Greenfield’s continued leadership.
Lady Greenfield, 59, has a reputation as one of Britain’s most colourful and influential scientists, but also as one of the most outspoken and controversial. The Professor of Pharmacology at the University of Oxford, who studies disease of the brain, regularly appears on television and is acknowledged by her peers as one of the most talented communicators of science of her generation.
Her unconventional approach to courting publicity, however, has annoyed as many scientists as it attracts, some of whom claim that her talent for self-promotion outweighs her scientific credentials. She has been rejected as a candidate for fellowship of the Royal Society, the elite national academy of science.

Is breast really best? Professor defies official advice and says formula milk as just as good
Breast milk is no better for a baby than formula, an expert claimed last night as he reignited the 'breast is best' debate. Professor Sven Carlsen said breast-fed babies were slightly healthier, but it was not the milk that made the difference. Instead, babies who are breast-fed have benefited from better conditions in the womb before birth. The professor, an expert in the hormonal changes of pregnancy, claimed: 'Baby formula is as good as breast milk.'
The bold statement will enrage the 'breast is best' lobby, who say a mother's milk wards off a host of ills. It will also confuse mothers who are under pressure from the Department of Health to feed their babies on breast milk alone for the first six months of life. NHS leaflets tell mothers that breast-feeding exclusively for the first six months will help protect their baby against obesity, eczema and ear, chest and tummy bugs. Avoiding formula, they are told, will cut the odds of a child being a fussy eater in later life, as well as cut the woman's odds of some cancers and help with weight loss.
But Professor Carlsen, from the Norwegian University of Science and Technology in Trondheim, spoke out after carrying out a review of more than 50 studies into the relationship between health and breast-feeding. Most concluded that the longer a child is nursed, the healthier it will be. The professor said this may be the case, but it was because of a healthier pregnancy, not the breast milk. His research shows that high levels of the male sex hormone testosterone in the womb affect a woman's ability to produce milk and to breast-feed.
With testosterone levels affected by the health of the placenta, which ferries oxygen and nutrients to the baby, the professor believes high amounts indicate poorer conditions in the womb overall. This means that any differences in the health of a baby bottle-fed because its mother finds breastfeeding difficult are set before birth, rather than afterwards.
But Royal College of Paediatrics and Child Health spokesman Charlotte Wright said the claims were 'irresponsible and overblown'. She said: 'Women should remember that we were not designed to be bottle-fed - formula is an artificial alternative.'
Clare Byam-Cook, a former midwife who has taught celebrities such as Kate Winslet and Natasha Kaplinsky how to feed their babies, said breast-feeding was not suitable for all. She said: 'How a mother looks after herself and her growing baby in pregnancy is the most important thing that she can do. 'Once the baby is out, of course I would advocate breastfeeding. But if the mother can't do it she shouldn't pursue it too much and she certainly shouldn't feel guilty.'

The anti-Alzheimer's milkshake: Once-a-day drink that boosts memory
The gain seems to be slight in absolute terms and may not survive replication. That 24% given a dummy drink also showed improvement is cautionary. That's slightly below the normal placebo effect. One wonders about how double-blind the study was. Though it could be that Alzheimers patients are less likely to be influenced by placebo treatments
A memory-boosting milkshake for Alzheimer patients could be available within two years. Tests show that taken once a day with breakfast, the strawberry shake significantly improves short-term memory in those in the early stages of the devastating disease. The changes were apparent after only 12 weeks, providing ‘compelling evidence’ of the drink’s potential, the journal of the American Alzheimer’s association reports.
Further, large-scale trials of Souvenaid, which contains a cocktail of brain nutrients found naturally in breast milk, are already under way. If they are successful, it could be marketed by Shape and Actimel manufacturer Danone. It is likely to be displayed behind-the-counter in pharmacies and sold after a brief consultation, in a similar way to some cough mixtures.
Researcher Professor Richard Wurtman said: ‘This is something that has no toxicity, that gives you better function than you started with. If it works in the follow-up studies, it is very exciting.’
Alzheimer’s and other forms of dementia blight the lives of 400,000 Britons and their families – and the number of cases is expected to double within a generation. There is no cure and existing drugs, which raise levels of key brain chemicals, do not work for everyone and their effects wear off over time.
Rather than targeting brain chemicals, the drink focuses on the connections that carry vital messages between brain cells. Damage to these connections, or synapses, is blamed for many of the symptoms of Alzheimer’s disease, including memory loss. Professor Wurtman, of the Massachusetts Institute of Technology in Boston, pinpointed the compounds which work together to make new connections. The three key ingredients – omega-3 fatty acids, uridine and choline – are all found in breast milk. Other ingredients include B vitamins and health-boosting antioxidants.
The milky ‘cocktail’ was tested in elderly men and women in the early stages of Alzheimer’s. Half were asked to take the drink with breakfast for three months and half were given a substitute drink which looked and tasted the same but lacked the key ingredients. They were then given a battery of memory tests, including one in which they were questioned on details of a story around half an hour after being told it. This type of short-term memory loss is typical of Alzheimer’s.
Those taking Souvenaid were almost twice as likely to score better at the end than at the beginning of the three-month trial, the journal Alzheimer’s & Dementia reports. Overall, 40 per cent of those who had taken Souvenaid showed improvement, compared with 24 per cent given the dummy drink.
The drink did not produce improvements in scores for tests of orientation and spatial awareness – but this may be because these traits do not tend to fade until later in the illness.
Flemming Morgan, of Danone, which funded the research, said: ‘Our goal is to make a proven and positive difference in the lives of millions of people with Alzheimer’s and their carers.’
In Britain, Rebecca Wood, chief executive of the Alzheimer’s Research Trust, said: ‘It’s very early days, but this study does suggest that this multinutrient drink is worthy of further investigation.’

Mobile phone use may reverse Alzheimer's - study
LOL! This is going to freak the cellphone haters!
TALKING on a mobile phone could be good for you, because the electromagnetic waves emitted by the devices could protect against and even reverse Alzheimer's disease. Researchers at the University of South Florida exposed 96 mice, most of whom had been genetically altered to develop the Alzheimer's disease as they aged, to electromagnetic waves generated by US mobile phones.
The mice were zapped with 918MHz of frequency twice a day for one hour each time over a period of seven to nine months - the equivalent of several decades in humans. In older mice with Alzheimer's, long-term exposure to the electromagnetic fields caused deposits in the brain of beta-amyloid, a protein fragment that accumulates in the brain of Alzheimer's sufferers to form the disease's signature plaques, to be erased. Memory impairment in the older mice disappeared, too, the study showed.
Young adult mice with no apparent signs of memory impairment were protected against Alzheimer's disease after several months of exposure to the mobile phone waves, the study showed. And the memory levels of normal mice with no genetic predisposition for Alzheimer's disease were boosted after exposure to the electromagnetic waves.
The study was the first to look at the long-term effects of mobile phone exposure in mice or humans and its findings took even the researchers by surprise. "Frankly, I started this work a few years ago with a hypothesis that the electromagnetic fields from a mobile phone would be deleterious to Alzheimer's mice," lead author Gary Arendash, a professor at the University of Southern Florida, said. "When we got our initial results showing a beneficial effect, I thought, 'Give it a few more months and it will get bad for them'. "It never got bad. We just kept getting these beneficial effects in both the Alzheimer's and normal mice."
Based on the findings in mice, the researchers hoped electromagnetic field exposure could be an effective, non-invasive and drug-free way to prevent and treat Alzheimer's disease in humans.

Taking the “Human” out of “Humane”
We took a look last week at some details of the 2008 tax return filed by the deceptive Humane Society of the United States (HSUS). The filing shows that HSUS paid out less than one-half of one percent of its $99 million budget to hands-on dog and cat shelters. Meanwhile, a large portion of the kitty – tens of millions of dollars – went to employee salaries and animal rights lobbying. And all this expensive chicken-hugging has a hidden price. To find it, try visiting your local unemployment office.
In 2008 HSUS spent more than $2.3 million on a political committee called “Californians for Humane Farms,” which campaigned for the “Proposition 2” ballot initiative in the Golden State. In 2007, it gave over $1.3 million. HSUS also made donations of $200,000 in 2007 and 2008 to the “Committee to Protect Dogs,” a Massachusetts organization that pushed for a statewide ban on greyhound racing with the “Question 3” ballot initiative.
Both ballot campaigns were successful. And both had human costs. In California, a UC Davis study estimated that Prop 2 would destroy the state’s egg industry by adding 20 percent to the cost of egg production and causing companies to move to other states or to Mexico. In real numbers, the study found, Prop 2 was expected to cost more than 3,000 jobs and take more than $615 million out of the state’s already precarious economy. In Massachusetts, 1,000 people were expected to lose their jobs after the racing ban took effect last week. We love dogs too, but when people lose their jobs, who’s going to buy them kibble and flea collars?
All told, HSUS’s leaders spent more than $4.1 million on two political battles, and put an estimated 4,000 workers out of business. And that doesn’t include similar political “committees” HSUS has bankrolled in Michigan, Colorado, and Arizona. Who knows how many jobs HSUS will kill this year in Ohio alone?
Sure, HSUS claims it does everything “for the animals.” But what about people? How many American workers and their families are left unemployed in the wake of animal rights campaigns? And why doesn’t HSUS put a serious amount of money into pet shelters, where animals can be helped and jobs created?
There are human costs to HSUS’s crusades. But when cows and pigs are all you care about, people can get lost in the shuffle. Today’s overfed animal activists are clearly willing to put Americans in the bread line. Just don’t expect any chicken soup when you get there.

Now bacon and eggs are good for you!
The food freaks won't like this. The anti-meat brigade have got most pregnant women warned off bacon and smoked meats by now. They could have damaged a lot of children. It's only a mouse study below but it serves as a warning that food fads could do harm
Eating a traditional breakfast of bacon and eggs could help pregnant women boost the intelligence of their unborn child, a new study suggests. Scientists have found that a chemical in pork products and eggs can help the growing brain to develop. A new study suggests that the micronutrient, called choline, is critical to helping babies in the womb develop parts of their brains linked to memory and recall.
Previous studies have demonstrated that a woman’s diet during pregnancy can affect her unborn child and women are given a list of foods to avoid until their baby is born. Scientists at the University of North Carolina tested the effects of choline on the brains of baby mice. Mice fed a low choline diet while in the womb had genetic differences in their brain cells than those given large amounts of the micronutrient. "Our study in mice indicates that the diet of a pregnant mother, especially choline in that diet, can change the … switches that control brain development in the foetus," said Steven Zeisel, who led the study.
Dr Gerald Weissmann, editor-in-chief of the Federation of American Societies for Experimental Biology journal, which published the research, said: "We may never be able to call bacon a health food with a straight face, but (similar studies are) already making us rethink those things that we consider healthful and unhealthful.
“This is yet another example showing that good prenatal nutrition is vitally important throughout a child's entire lifetime."

Eating huge quantities of pomegranates may help prevent breast cancer
Another bit of nonsense coaxed out of laboratory glassware

Eating pomegranates could reduce the risk of breast cancer, researchers have said. Scientists have found chemicals in the fruit being hailed as a superfood after the launch of several juice drinks play a key role in blocking the growth of breast cancer. The study may lead to new drugs to prevent cancer and in the meantime the researchers said eating more of the fruit may be beneficial. Tests in the lab have found that the chemicals called ellagitannins block the production of oestrogen which can fuel the growth of cancer cells.
The study is published in Cancer Prevention Research, a journal of the American Association for Cancer Research. Experts said it unclear how much of the chemicals would be required to have an effect in humans and it may not be possible to gain enough from diet alone. Prof Gary Stoner, professor in the Department of Internal Medicine at Ohio State University, said that "relatively high levels of ellagitannin compounds" were needed in the study to have an effect. He added "It's not clear that these levels could be achieved in animals or in humans because the ellagitannins are not well absorbed into blood when provided in the diet."
He said the findings were promising enough to warrant further studies with pomegranates. Prof Stoner added people "might consider consuming more pomegranates to protect against cancer development in the breast and perhaps in other tissues and organs."
Dr Powel Brown, medical oncologist and chairman of the Clinical Cancer Prevention Department at the University of Texas M D Anderson Cancer Centre, said: "More research on the individual components and the combination of chemicals is needed to understand the potential risks and benefits of using pomegranate juice or isolated compounds for a health benefit or for cancer prevention."

Forget Viagra! Sound waves can send your sex life into orbit
This is another attempt to get at causes and may be worthwhile if a full trial is successful
Firing shock-waves into the body could be a radical new way to boost the love lives of men with erection problems. The pain-free therapy boosts performance by stimulating the growth of new blood vessels in the genital area. A small trial involving 20 men who were taking Viagra or similar drugs for impotence problems was so successful that, by the end of the experiment, 15 of them were able to throw their pills away. None of the volunteers reported any pain or side-effects from the treatment.
The radical new therapy, which is on trial in Israel, uses a very mild form of lithotripsy, a technique developed more than 20 years ago for the treatment of kidney stones. Waves of sound are beamed through the skin, and although they pass harmlessly through body tissue, they are at just the right pressure to smash up kidney stones into tiny sand-like particles that are then passed out of the body in urine.
But in recent years, several studies have also shown that this type of shock-wave therapy appears to have a healthy effect on blood vessels. It triggers the release of an important substance called Vascular Endothelial Growth Factor, or VEGF, which sends out a signal for new blood vessels to start growing. As a result, shock-wave therapy has also attracted increasing interest from cardiologists looking for new ways to treat heart disease. U.S. and Japanese researchers are investigating whether firing shock-waves towards the heart will help it sprout healthy new blood vessels. If so, it could offer a lifeline to patients who are too ill to undergo heart bypass surgery.
According to Israeli research, the same benefits could help men who suffer persistent erection problems. Some health experts are now convinced there is a close link between impotence and heart disease, and that problems in the bedroom can often signal hidden blockages in blood vessels near the heart which are reducing blood flow around the body.
Doctors at the Rambam Medical Centre in Haifa, Israel, recruited 20 men with an average age of 56 to take part in the trial. All 20 were already on medication and had suffered mild to moderate erection problems for an average of three years. During the three-week course of treatment, low-intensity shock-waves were repeatedly fired into five specific points in the genital area, using a handheld device.
Doctors then assessed the severity of the men's ailments on a 30-point scale called the International Index of Erectile Dysfunction, widely used to measure impotence problems. The lower the score, the greater the problem. Before the trial, the men averaged scores of between 12 and 20 points, which meant they had mild to moderate sexual dysfunction. But after treatments, their scores increased by between five and ten points. Experts say anything in excess of five points is a significant improvement.
Viagra and similar medications, such as Cialis and Levitra, have transformed the treatment of impotence in the past ten years, around 30 per cent of men who take them see no improvement. For these men, the only other options are to inject drugs straight into the penis, or use a pump that manually increases blood supply to the organ.
Dr Yoram Vardi, who led the trial, says: 'Drugs are not a cure. When patients stop taking their medication, then they cannot function. 'With shock-waves, we can do something biological for the problem. These patients can then function without the need for medication.'
Dr John Dean, president of the International Society of Sexual Medicine, said the findings were 'intriguing' and worth following up in larger studies. But he warned that earlier attempts to use shock-wave therapy for another condition called Peyronie's disease - where the penis is bent and painful when erect - had failed. 'These findings are interesting and definitely warrant further investigation,' Dr Dean said. 'But we are a long way off saying that men should go to their GP asking for this treatment.'

Politically correct food on the menu in Britain
From foie gras produced without making birds suffer to 'sustainable' fish, British retailers and restaurants are embracing politically correct food
Faux (false) gras is the ethical answer to the dilemma that attends the foodstuff, which has been the bane of campaigners for decades. It is produced by force-feeding ducks or geese to create engorged livers that yield the creamy pate. Waitrose, House of Fraser and Tesco are among a growing number of major British retailers that are refusing to stock real foie gras after protest campaigns.
Even Selfridges, one of the main attractions for discerning shoppers on Oxford Street, decided in November to take foie gras off its shelves after a protest fronted by Sir Roger Moore, the former James Bond actor. "It's torture in a tin," said Moore, who appeared on pre-Christmas posters urging Selfridges to halt its sale, with the words: "Force-feeding birds is not yule, it's cruel."
The foie gras ban has even gained the royal seal of approval after Prince Charles, the heir to the throne, ordered it off menus for royal functions.
Waitrose developed the faux gras version - produced without force-feeding the birds - and calls it an "ethical alternative to traditional foie gras". A darker colour than the real thing, faux gras is made from about 50 per cent liver from free-range poultry blended with goose or duck fat. Two years after its introduction, Waitrose customers appear to be increasingly happy to substitute faux gras for the real thing at Christmas and New Year. "Faux gras is still one of our most popular festive foods," said a Waitrose spokeswoman, who added that sales of the new product grew by almost 60 per cent in 2009.
Such is the popularity of the new, more "ethical" version of the product that lawmakers have backed a motion calling for restaurants to adopt the new version and ditch the real foie gras. "It is only a matter of time before foie gras is relegated to the history books where it belongs," said Sam Glover of lobby group Peta (People for the Ethical Treatment of Animals).
While the day that five-star establishments abandon such foods may be some way off, restaurants in England do seem to be turning towards "green" alternatives. Acorn House, in the King's Cross district of London, claims to be the "first truly eco-friendly" restaurant in the capital. The duck it serves comes from birds raised in a "positive" way, without cages and without antibiotics added to their food; its food deliveries are made in vehicles using biofuel, 80 per cent of its waste is recycled and its roof is a herb garden. "Acorn House is set to alter the image of the restaurant industry as well as transform the way in which people eat out," is the bold claim of its co-founder Arthus Potts.
French celebrity chef Raymond Blanc, the holder of two Michelin stars at his renowned restaurant Le Manoir aux Quat' Saisons near Oxford, has embraced a campaign to use fish certified by the Marine Stewardship Council (MSC). This label guarantees that the fish has been obtained from sustainable stocks. "By supporting MSC, I am helping to ensure that fish stocks will be replenished for generations to come," said Blanc, a well-known face in his adopted country thanks to regular TV appearances.
There are 14 MSC-certified restaurants in Britain and although the number remains relatively low, the non-profit organisation argues that its campaign is putting pressure on other restaurants to change their ways.
The main target of the protesters is Nobu, the global chain of chic Japanese restaurants which has the financial backing of Robert De Niro, the actor, and a strong following among the rich and famous. Nobu's Michelin-starred London branch is refusing to remove bluefin tuna, an endangered species, from its menu. Elle Macpherson, a model, Sienna Miller, an actress, and Stephen Fry, a TV presenter and actor, all added their names to a petition protesting against the restaurant's use of the endangered fish.
The restaurant responded by adding an asterisk next to the dish on its menu, directing diners to a footnote saying: "Bluefin tuna is an environmentally threatened species. Please ask your server for an alternative."

Heart attack and stroke fears over fat-busting "wonder pill"
A fat-busting pill used by thousands in the UK is being investigated by medicines watchdogs over fears it could cause heart attacks and strokes. The European Medicines Agency (EMA), which licenses the use of the drug Reductil, is looking at the results of a clinical trial which suggests that its active ingredient, sibutramine, could lead to an increased risk of developing heart problems. Nearly 330,000 prescriptions for the drug, which tricks the brain into believing the stomach is full, were written out in 2008.
The safety data has come from an international trial of 10,000 patients carried out during the past six years. Most of those recruited for the Sibutramine Cardiovascular Outcome Trial (SCOUT) were overweight or obese and already had cardiovascular problems. A heart condition would normally exclude them from taking the drug because it can slightly raise blood pressure. However, the EMA has said that, as a result of the ‘seriousness’ of the study’s concerns, it is looking at the implications for all patients offered the prescription-only drug and will release its findings later this month. Until then, it has advised doctors to use Reductil ‘with caution’ and to monitor patients’ blood pressure and heart rate.
The UK’s medicines watchdog, The Medicines and Healthcare Products Regulatory Agency, also confirmed it was reviewing the data. The agency has recorded 2,094 suspected adverse reactions to Reductil since it was introduced in 2001, and 17 deaths have been linked to the drug. Six of the deaths were caused by heart problems and strokes.
Reductil works by blocking the nerve cells that release and reabsorb the hormone serotonin, a chemical neurotransmitter in the brain that affects moods and appetite. As the level of serotonin in the body rises, people feel fuller, eat less and, as a result, lose weight.
The drug is recommended for patients who are clinically ‘obese’ – those with a Body Mass Index over 30 – or for anyone with a BMI higher than 27 who has another weight-related health problem.
A spokesman for Abbott Laboratories, which manufacturers Reductil, said: ‘Our ongoing evaluation of the SCOUT study data does not change our medical assessment of sibutramine’s risk/benefit profile when used appropriately in the approved patient population. 'Sibutramine is an important treatment for patients who are obese.’

The alcohol merrygoround again
Champagne Is Good for Your Heart, Study Suggests -- But Only in Moderation, natch. I would have thought that the effects described could be due to alcohol alone -- as alcohol is a vasodilator and that too would help blood flow
Research from the University of Reading suggests that two glasses of champagne a day may be good for your heart and circulation. The researchers have found that drinking champagne wine daily in moderate amounts causes improvements in the way blood vessels function.
Champagne does this by increasing the availability of nitric oxide, a vascular active molecule which controls blood pressure. It is able to induce these effects because it contains polyphenols, plant chemicals from the red grapes and white grapes used in champagne production.
When you drink champagne, these polyphenols get absorbed into the circulation where they are able to act on the vascular system. Specifically, they appear to slow down the natural removal of nitric oxide from our blood, meaning that it will have a longer time to act on blood vessels and so improve the flow of blood around the body.
High nitric oxide levels in the blood, as a result of drinking champagne, can have beneficial effects, because as well as increasing blood flow, it may help to decrease both blood pressure and the likelihood of blood clots forming. This could therefore reduce the risks of suffering from cardiovascular disease and stroke, but more research needs to be done to determine the long term effects of daily champagne consumption.
Dr Jeremy Spencer, from the Department of Food and Nutritional Sciences said: "Our research has shown that drinking around two glasses of champagne can have beneficial effects on the way blood vessels function, in a similar way to that observed with red wine. We always encourage a responsible approach to alcohol consumption, but the fact that drinking champagne has the potential to reduce the risks of suffering from cardiovascular diseases such as heart disease and stroke, is very exciting news."

Another "magic bullet" dream
Publicity first; evidence later. Not a good sign. Interferon has been around for years anyway and is of very limited use
A lozenge designed to fight off all cold and flu bugs has been created by scientists. It would be taken once a day before breakfast and would cost only 20p a day. The lozenge could be sold over-the-counter in as little as two years. It would prime the immune system to attack every cold and flu bug including 'normal' winter flu, swine flu and bird flu.
The lozenge, which tastes like a sweet and dissolves in the mouth, could be used to clear up sniffles in healthy people and prevent life-threatening infections in the elderly and in asthma and cystic fibrosis sufferers. It has already been tested on people and the first results are due within weeks.
Researcher Professor Manfred Beilharz said: 'This is the golden fleece everyone has been looking for.' The Veldona lozenge contains tiny amounts of interferon alpha, which was nicknamed the 'Crown jewel' of virology when it was discovered 50 years ago. Interferon alpha is a protective protein that the body naturally makes when attacked by a virus. When the lozenge dissolves in the mouth, the protein is released and the immune system is tricked into thinking there is a bug nearby and gets ready for a fight.
Professor Beilharz, who has devoted 15 years to the research, said: 'The outposts of the immune system say, "Hey, we've got a virus, let's gear up and get ready for it before the infection spreads too far."'
The professor has already shown that very low doses of the protein can save the lives of mice exposed to an otherwise lethal cocktail of the flu virus. These 'stunning' results prompted a government-funded trial of the lozenge on 200 adults in Western Australia. Half took the lozenge once a day before breakfast, half took a dummy sweet and all noted any cold and flu symptoms each week, including time off work.
If the results are good, the lozenges, which were developed by U.S. firm Amarillo Biosciences, could be fast-tracked onto pharmacy shelves within two to three years. They could be taken year-round, but people are most likely to rely on them over the winter.
Professor Beilharz, chairman of the department of microbiology and immunology at the University of Western Australia in Perth, expects them to be sold over-the-counter, rather than on prescription, and to be much cheaper than current anti-flu drugs. Tamiflu, which has been stockpiled by governments around the world to treat swine and bird flus, costs up to £5 a tablet. The lozenges could cost as little as 20p each, or £6 a month.
Professor Beilharz said: 'This medicine is quite cheap to manufacture and very low dosage and doesn't seem to have any side-effects of any significance.' Unlike the flu vaccine, which has to be frequently reformulated to fight whichever strains of the bug are circulating, it would be a 'one-size-fits all' drug. This is because interferon alpha primes the immune system to fight a range of viruses, including all cold and flu bugs.
The professor said: 'The vaccine is only good for a particular variant and there may have to be another one the next year, whereas our little baby is not just good against influenza, it is good against all winter cold variants.'
The professor does not expect the drug to completely ward off flus and colds, but symptoms will be greatly eased. He said: 'When the infection comes along, it still infects but the immune system quashes it in a couple of days. 'So you will have some symptoms but they will be rather mild and you will go on as normal.'
Interferon alpha was used by the Russians to treat colds and flus during the Cold War but never took off elsewhere. But injections of much higher doses are used to treat diseases, including multiple sclerosis. Professor Hugh Pennington, Britain's leading microbiologist, cautioned that the side-effects of interferon could be worse than the flu itself.
But he added: 'If you can work out the right dose and the right kind of interferon so people don't feel grotty, and it works, it will be a real breakthrough. So let's wait and see.'

Engineer shows surgeons better way to fix his heart
A heart repair kit designed by a man suffering from a potentially lethal condition has proved so successful that it is being used on other cardiac patients. Tal Golesworthy, 54, an engineer by training, was suffering from a defect in his aorta — the main artery for carrying oxygenated blood — that left it in danger of splitting, which would have caused instant death. He was so unimpressed by conventional techniques for treating it that he decided to create his own.
Usually the damaged section of the artery is cut out and replaced with a piece of tubing, but Golesworthy came up with a made-to-measure knitted polyester sleeve, which was wrapped round the aorta to give it extra support. The result was so good that Golesworthy has joined forces with his doctors and set up a company to market the device. The operation has since been carried out on a further 19 people by a team at London’s Royal Brompton hospital, and another three patients are booked in for surgery this month. Details of the first results are to be described to cardiac surgeons in a medical publication this month.
Golesworthy suffers from Marfan syndrome, a condition which affects up to 12,000 people in Britain. The genetic defect can cause abnormal growth of bones including fingers and toes, but most importantly causes weakness of connective tissue. The consequence is that the neck of the aorta where it leaves the heart gradually stretches under the burden of carrying freshly oxygenated blood round the body. It can reach a diameter of 2-4in, compared with a normal 1in, before fatally splitting.
Golesworthy says he had severe anxieties about the old-style surgery, and the fact he would have had to take anticoagulant drugs for the rest of his life to stop clots forming. “I just thought the operation sounded awful,” said Golesworthy, from Tewkesbury, Gloucestershire. “The doctors were being asked to do an engineering job when they weren’t engineers. I decided there had to be a better way.”
He set about devising a means of wrapping the aorta in a sleeve to prevent it expanding, and came up with a solution called Ears — external aortic root support — which is now being marketed through his firm, Exstent. Each sleeve is created using scans of the individual patient’s aorta and computer-assisted drawing to produce a bespoke device.
Although the technology could be applied to other heart conditions, news of the surgical breakthrough has spread first among families affected by Marfan syndrome, many of whom have seen relatives die suddenly from heart attacks in young adulthood.
The youngest to have the surgery so far is Ami Coxill-Moore, whose parents successfully argued for her to receive an Exstent at 16, even though an ethics committee initially stipulated that the experimental patients had to be at least 18. “To us it was obvious it was less risky and an altogether better operation,” said Coxill-Moore, who is taking a gap year and hoping to study English and linguistics at York University. “I am just very grateful I’ve had it done.”
The British Heart Foundation is watching the project with interest. “We welcome it as a new development, but we have to be certain these things are safe in the long as well as the short term, before we can recommend them,” said Peter Weissberg, its medical director.

Vitamin D and older adults: More than just a bone problem?
I like the last sentence below. The Buell et al study was of very elderly people so is of limited generalizability and may suggest that vitamin D deficiency is just one aspect of poor health and diet. The same applies to the Anweiler study
This issue of Neurology features 3 studies on the possible link between vitamin D and cognition (or thinking) in older adults. The first study looked at the possible link between vitamin D levels and cognition in older women. Dr. Annweiler and coauthors1 studied 752 women aged 75 years and older who lived in France. Levels of 25(OH)D, the form of vitamin D found in the blood, were measured. Patients took a cognitive test called Pfeiffer's Short Portable Mental State Questionnaire (SPMSQ). In this study, low levels (or deficiency) of vitamin D were defined as a 25(OH)D blood level less than 10 (ng/mL). Cognitive impairment was defined as a score of less than 8 (out of 10 points) on the SPMSQ. Seventeen percent had vitamin D deficiency. Women with vitamin D deficiency had lower scores on the SPMSQ and were more likely to have cognitive impairment than those without vitamin D deficiency. The authors found that vitamin D deficiency was associated with cognitive impairment in older women.
The second study looked for links between vitamin D levels, cognition, and strokes in older men and women. Dr. Buell and coauthors studied 318 men and women between 65 and 99 years old in the Boston area. These patients had low income levels, lower functional status, and need for food or personal care. The researchers checked 25(OH)D blood levels and did cognitive testing. Patients had pictures taken of the brain using magnetic resonance imaging (MRI). Vitamin D "deficient" was defined as 25(OH)D blood levels less than 10 ng/mL, and vitamin D "insufficient" was defined as 25(OH)D blood levels between 10 and 20 ng/mL. MRI changes in the large or small vessels in the brain were used to show if there were strokes or cerebrovascular disease. Approximately 15% of the patients were vitamin D deficient, and 44% were vitamin D insufficient. About 24% had dementia. Lower vitamin D levels were linked to dementia and MRI changes in the large and small vessels in the brain. The authors found that those with lower vitamin D levels were more likely to have dementia, strokes, and disease in the blood vessels to the brain.
The final study looked at vitamin D levels and cognition in elderly men. Dr. Slinin and coauthors3 studied 1,604 men aged 65 years and older in 6 cities. 25(OH)D blood levels were measured, and patients took 2 cognitive tests: the Modified Mini-Mental State Examination (3MS) and a timed test called Trail Making Test Part B (TMTB). The patients were divided into 4 groups, based on 25(OH)D levels. After considering race and education, there was no link between lower vitamin D levels, lower scores on the 3MS, or longer time to complete the TMTB. The authors found that there was not a link between lower vitamin D levels and cognitive impairment in older men.
It is well known that vitamin D deficiency can affect bone health. However, other research shows a possible link between vitamin D deficiency and other disorders. These can include heart disease and diabetes.4 Two out of 3 studies in this issue found that vitamin D deficiency may be linked to cognitive impairment.
The table shows that the authors studied different groups of people, used different definitions of vitamin D status, and had different tests for cognitive function. As a result, we cannot be certain about the link between vitamin D deficiency and cognitive changes.

Taking herbal supplement to ward off memory problems in old age 'a waste of time'
Thousands of people who take a herbal supplement to ward off memory problems in old age are wasting their time, according to new research. Elderly people who took Ginkgo biloba every day for six years had as many difficulties with recall as those who took a fake supplement, the largest study of its kind has shown.
At least 100,000 people in Britain are thought to regularly take the supplement, which has been widely credited with improving memory and concentration. Made from the leaves of the Ginkgo tree, the Chinese herbal remedy has been used as a traditional medicine for centuries. It is thought to contain chemicals which help the flow of blood around the body, which advocates believe will help protect the brain against decline.
But the researchers who carried out the latest study warned that the supplement appeared to have no effect on warding off age-related memory problems. Beth Snitz, from the University of Pittsburgh, who led the study, said: “Ginkgo biloba is marketed widely and used with the hope of improving, preventing, or delaying cognitive impairment associated with ageing and neurodegenerative disorders such as Alzheimer's disease. “We (found) no evidence that Ginkgo biloba slows the rate of cognitive decline in older adults.”
For the study the team followed 3,069 volunteers, all of whom were aged between 72 and 96 years old and were given either a dose of the herbal supplement or a placebo twice a day for more than six years. The findings are published in the Journal of the American Medical Association (JAMA).

Infectious cancer
The media seem generally to be playing the significance of this down but it would seem to be a warning of what is possible in humans. Cancer is normally a degenerative disease, not an infectious disease

AN international team of scientists has discovered the genetic marker for a deadly cancer ravaging the Tasmanian devil population, and they say their findings pave the way for developing treatments. Researchers analysed tumour cells taken from facial cancers in the animals, the world's largest marsupial carnivores, and found the disease probably starts in Schwann cells - a type of tissue that cushions and protects nerve fibres.
"Our findings represent a big step forward in the race to save the devils from extinction," said Elizabeth Murchison, who works with the US Cold Spring Harbor Laboratory and the Australian National University.
Deadly facial tumour disease (DFTD) has ravaged the wild population. Australia raised protection levels for devils in May and listed them as endangered due to DFTD. DFTD is a unique type of cancer, transmitted from animal to animal via biting or other physical contact, which transfers living cancer cells between individuals. Only two cancers are known to spread in this way - the other is found in dogs. The devils' tumours are mostly found on the face and mouth, but often spread to internal organs.
Writing in the journal Science, the researchers said that, with no diagnostic tests, treatments or vaccines currently available, the disease could wipe out the entire species in 25 to 35 years.
The team's genetic analysis confirmed that tumours spread from animal to animal are genetically identical because they originate from a single line of cells. Using advanced sequencing technology, the team identified the originating cell by comparing the "transcriptome" - the complete set of genes that are turned on in tumour cells -- with a genetic readout of other tissues. The scientists found the tumours' genetic signature best matched that of Schwann cells, but said they were still unclear about how these nervous system cells spawned cancer.
Identifying the genetic marker could help accurately diagnose the disease and help to develop treatments, they said. "Now that we've taken a good look at the tumours' genetic profile, we can start hunting for genes and pathways involved in tumour formation," said Greg Hannon, who worked on the study.
The study will also help scientists distinguish between DFTD and other types of devil cancers, helping them to identify and isolate affected animals and contain the disease's spread.

More than a third of health workers believe coffee causes cancer despite no evidence of a link, according to a survey
Good to see the WCRF being a bit skeptical this time. They still talk nonsense about diet, though.
Health professionals are less likely to be clued up than the public, with 36 per cent thinking coffee can cause the disease compared with 12 per cent of the general population. The World Cancer Research Fund (WCRF) commissioned the survey of 143 NHS workers, including nurses, health visitors and GPs.
However, health professionals did score highly on knowing that poor diet increases risk of cancer (81 per cent), compared with 63 per cent for the general public. Overall, 79 per cent of workers were aware that being overweight increases the risk of cancer, compared with 60 per cent of the public, and 78 per cent knew of the link with alcohol, compared with 51 per cent of the public.
But the percentage who were aware that not exercising increases the risk of cancer dropped to 64 per cent among NHS workers and 47 per cent of the public.
Silvia Pastorino, health professionals publications manager for the WCRF, said the survey was small but revealed some health workers are still not aware what lifestyle factors increase the risk. She said: "There is no strong evidence that coffee increases the risk of cancer. "In fact, we often suggest drinking unsweetened tea or coffee as an alternative to sugary drinks. "While I am not surprised that many of the general public are not aware of this, it is worrying to think this may also be the case for some health professionals."
