NICE is getting above itself -- entering the diet wars

Their job is to evaluate the economic effectiveness of drug therapies -- a job they do badly, according to most. But they are apparently a very ambitious little bureaucracy so are now striking out in new directions. But the statements below are just conventional crap showing no knowledge of the double blind studies. If that is testament to their scholarly standards, no wonder they do their original job in a way so disappointing to many

More than 40,000 Britons are dying unnecessarily every year because of high levels of salt and fat in their diets, the Government’s public health watchdog Nice has warned. The National Institute for Health and Clinical Excellence (Nice) says that unhealthy foods have wreaked a “terrible toll of ill health” on the nation and placed a “substantial” strain on the economy.

For the first time, the organisation publishes landmark guidance on how to prevent the “huge number of unnecessary deaths” from conditions such as heart disease that are linked to the consumption of ready meals and processed food.

It calls for sweeping changes to food production and government policy to encourage lifestyle changes, and to reduce significantly the amount of salt and saturated fat the nation consumes.

It says “toxic” artificial fats known as trans fats, which have no nutritional value and are linked to heart disease, should be banned. The organisation says that ministers should consider introducing legislation if food manufacturers failed to make their products healthier.

Nice says it has brought together all the available evidence to illustrate the link between unhealthy food and public health, partly in response to increasing concern about obesity in Britain, particularly among children.

It says there are about five million people in the country suffering the effects of cardiovascular disease — a “largely avoidable” condition that includes heart attacks, heart disease and stroke — and that it causes 150,000 deaths annually. Nice says 40,000 of these deaths could be prevented, and hundreds of millions of pounds saved, if its measures were introduced.

The guidance, which was commissioned by the Department of Health, also recommends that:

• Low-salt and low-fat foods should be sold more cheaply than their unhealthy counterparts, through the use of subsidies if necessary;

• Advertising of unhealthy foods should be banned until after 9pm and planning laws should be used to restrict the number of fast food outlets, especially near schools;

• The Common Agricultural Policy should focus more on public health, ensuring farmers are paid to produce healthier foods;

• Action should also be taken to introduce a “traffic light” food labelling system, even though the European Parliament recently voted against this;

• Local authorities must act to encourage walking and cycling and public sector caterers must provide healthier meals;

• All lobbying of the Government and its agencies by the food and drink industry should be fully disclosed.

Prof Klim McPherson, the Chairman of the Nice Guidance Development Group and professor of epidemiology at Oxford University, said: “Where food is concerned, we want the healthy choice to be the easy choice. Going even further, we want the healthy choice to be the less expensive, more attractive choice.

“Put simply, this guidance can help the Government and the food industry to take action to prevent huge numbers of unnecessary deaths and illnesses caused by heart disease and stroke.” The average person in Britain consumes more than eight grams of salt a day. The body only requires one gram to function. Targets are already in place to reduce salt consumption to six grams by 2015 and this should be extended to three grams by 2050, the guidance says.

Nice says children should consume considerably less salt than adults and that, because the bulk of salt in their diets comes from prepared food such as bread, cereal, soups, meat and cheese products, manufacturers have a significant role to play in reducing it.

The organisation says that most consumers did not even notice a difference in taste if salt levels were reduced by 5-10 per cent a year because their taste buds adjusted.

More crap here





'One size fits all' allergy jab for hay fever, asthma and eczema on the way

Sounds unlikely but one can only hope. The results reported from the small study below were fairly weak and there is no indication that they were double blind. Unless they were, the results are not impressive at all

A jab that could provide a "one size fits all" approach to tackling hay fever, asthma and eczema could be available within a few years, a conference heard.

Swiss researchers claimed allergies that blight the lives of 10 million British sufferers could be largely eradicated with a single vaccine. An allergy conference in London heard the “one size fits all” injection that wards off asthma, eczema, hay fever and even peanut allergies could be on the shelves within four to five years.

Experts say if the jab, known only as CYT003-Qbg10 which has been tested on humans, is properly developed it become the “hail grail” of vaccines due to it helping ward off multiple allergies. It would be welcome news to the estimated one in five Britons, or 10 million people, who suffer from hay fever.

A trial, conducted by scientists from Cytos Biotechnology, a firm based in Zurich, concluded that a course of the vaccine was almost as good as steroids at keeping asthma under control.

At the jab’s heart are pieces of synthetic DNA similar to those found in the bug that causes tuberculosis or TB. The DNA fools the body into thinking it is under attack from a dangerous bug, kick-starting a multi-pronged immune response.

A total of 63 asthmatic patients were given the course of the jab or a series of injections of a dummy drug over two or three months. Researchers found it cut asthma attacks or symptoms by a third.

In another trial, an injection every week over a month and half, cut the amount of runny noses and weepy eyes by almost 39 per cent. Quality of life was boosted by 42 per cent, they added.

Dr Wolfgang Renner, the chief executive of Cytos, told the Daily Mail the results were exciting. “We think it is a one-size-fits all mechanism,” he said. “We are very excited about it.”

Dr Renner suggested the first large-scale human trial could start next year and a vaccine within a few years.

A spokesman for Allergy UK said: “It does sound a very promising treatment, giving hope for those with severe asthma/allergy symptoms for whom the usual treatments aren’t enough, but there is still a long way to go before it will be available.”

Leanne Metcalf, director of Research at Asthma UK, added: “Over three quarters of people with asthma also have an allergy, which can often trigger their asthma symptoms. “We are, therefore, excited about the potential of this vaccine to make a real difference to people with asthma and allergies, especially as it has been shown in clinical trials to have relatively few side effects.”

Tuesday is thought to be the worst day of the year for hay fever.

The NHS currently estimates around ten million people suffer symptoms of hay fever – such as sneezing, runny nose and itchy eyes – in the spring and summer as grasses and trees release their pollen into the air.

But that number could reach 30 million within 20 years as city living, pollution and climate change exacerbate symptoms, experts warned earlier this year.
