Hurrah - eating red meat is good for you! After all the warnings, Sunday roast not linked to heart disease

No details are given of the study below but all the evidence I have seen that opposes meat eating is very weak -- motivated more by vegetarian convictions than anything else

After years of worrying that tucking into red meat could lead to a heart attack or cancer, you can relax and enjoy the Sunday roast, say researchers. A report demolishes the ‘myths and misconceptions’ about the meat, saying that most people eat healthy amounts which are not linked to greater risk of disease.

Modern farming methods have cut fat levels, which can be even lower than chicken, while red meat provides high levels of vital nutrients, including iron.

A vegetarian having a Cheddar cheese salad will eat seven times more fat, pound for pound, than lean red meat contains, says a review by the British Nutrition Foundation.

However, the World Cancer Research Fund, which advises people to curb red meat consumption and cut out processed meat, disputed the findings. [They would. Scares are meat and potatoes to them]

The 77-page review, which looks at current evidence on health and red meat, found no evidence of ‘negative health effects’. It shows on average men in the UK eat 96g of red meat and processed meat a day and women are eating 57g.

Those eating more than 140g a day are advised by the Scientific Advisory Committee on Nutrition to cut down, as these levels are linked to disease. There has been a cut in consumption over the last 30 years, with Britons eating less than many other European countries including Spain, Italy, France, Sweden and the Netherlands.

The review says there is ‘no conclusive link’ between cardiovascular disease and red meat, which actually contains some fatty acids that may protect the heart. At current levels of average consumption, there also is no evidence of a link to cancer, it says.

Cooking methods which overdo or char the meat are a much more likely cause of any link with bowel cancer, says the review.

Dr Carrie Ruxton, an independent dietician and member of the Meat Advisory Panel, which is supported by a grant from the meat industry, said: ‘This review highlights that eating red meat in moderation is an important part of a healthy balanced diet.

‘It also lays to rest many of the misconceptions about meat and health. People have been told they can’t eat it and they feel guilty when they do, but given that current intakes, on average, are well within health targets, there is no reason to eat less red meat if you enjoy it.’ An average slice of ham is 23g, beef 45g and a thick slice of lamb 90g. A small piece of steak is 100g.

Dr Ruxton said: ‘There is less saturated fat in a grilled pork steak than a grilled chicken breast with the skin left on.’

Although meat eaters often have more body fat than vegetarians, the review says it is impossible to attribute this to shunning meat as vegetarians tend to have more health-conscious lifestyles.

Dr Ruxton said many young women were iron-deficient and should be eating more red meat, but she advised that processed meat should be no more than an occasional treat. ‘You don’t need red meat every day, people should be eating fish twice a week, but if you ate a slice of red meat in a sandwich daily you can eat a portion of red meat for dinner up to four times a week and still stay within healthy limits,’ she said.

Since 2006 researchers have been giving hollow warnings about red meat. Professor Martin Wiseman, medical and scientific adviser for World Cancer Research Fund, said the study was being promoted by the meat industry, but added: ‘This paper is not a systematic review of the evidence and does not change the fact that there is convincing evidence that red and processed meat increase risk of bowel cancer. ‘This is why we recommend limiting red meat to 500g cooked weight per week and avoiding processed meat.

‘It is true that red meat contains valuable nutrients and this is why we do not recommend avoiding it altogether. But to suggest, as the authors of this review have done, that there is “no evidence” that a moderate intake of lean red meat has any negative health effects is wrong.

‘Essentially, the public has a choice between believing our findings – which are those of an independent panel of scientists after a systematic and transparent review of the complete global evidence – or the conclusions of this review.’

The review was published in the Nutritional Bulletin, the journal of the British Nutrition Foundation, a charity with funding from various sources including the food industry.

The tantalising evidence that belief in God makes you happier and healthier

I don't think there is much doubt that Christian religious belief de-stresses people. That alone could account for the correlations summarized below. And militant atheists seem such angry people -- and there is little doubt that chronic anger is bad for your heart

God has had a tough time over the past few years. On TV, in newspapers and on the internet, the debate as to whether faith has any relevance in a sceptical modern world has been as ubiquitous as it has been vigorous.

And it has been pretty clear which side is the most splenetic. From Richard Dawkins’ powerful atheist polemics to Christopher Hitchens’ public derision of the Roman Catholic Tony Blair and Stephen Hawking’s proclamation that the universe ‘has no need for God’, it seems that unbelievers have had the dwindling faithful on the run.

As research for my latest novel, Bible Of The Dead, I have spent months investigating the science of faith versus atheism, and discovered startling and unexpected evidence. It might just change the way you think about the whole debate, as it has changed my view.

I am not a religious zealot. On the contrary, I was a teenage atheist. And although in adulthood I have had a vague and fuzzy feeling that ‘there must be something out there’, I was never a regular church-goer. But what I have discovered, on my voyage through the science of faith, has astonished me.

My journey began a couple of years ago when I was travelling in Utah, the home of Mormonism. During my first week there, I approached this eccentric American religion with a typically European cynicism. I teased Mormons about their taste in ‘spiritual undergarments’; I despaired at being unable to find a decent cappuccino (Mormons are forbidden coffee, as well as alcohol, smoking, tea and premarital sex).

But then I had something of an epiphany. One night, after a long dinner, I was walking back to my hotel in downtown Salt Lake City at 2am and I suddenly realised: I felt safe. As any transatlantic traveller knows, this is a pretty unusual experience in an American city after midnight.

Why did I feel safe? Because I was in a largely Mormon city, and Mormons are never going to mug you. They might bore or annoy you when they come knocking on your door, touting their faith, but they are not going to attack you.

The Mormons’ wholesome religiousness, their endless and charitable kindliness, made their city a better place. And that made me think: Why was I so supercilious about such happy, hospitable people? What gave me the right to sneer at their religion? From that moment I took a deeper, more rigorous interest in the possible benefits of religious faith. Not one particular creed, but all creeds. And I was startled by what I found.

For a growing yet largely unnoticed body of scientific work, amassed over the past 30 years, shows religious belief is medically, socially and psychologically beneficial.

In 2006, the American Society of Hypertension established that church-goers have lower blood pressure than the non-faithful. Likewise, in 2004, scholars at the University of California, Los Angeles, suggested that college students involved in religious activities are more likely to have better mental and emotional health than those who do not. Meanwhile, in 2006, population researchers at the University of Texas discovered that the more often you go to church, the longer you live. As they put it: ‘Religious attendance is associated with adult mortality in a graded fashion: there is a seven-year difference in life expectancy between those who never attend church and those who attend weekly.’

Exactly the same outcome was recently reported in the American Journal of Public Health, which studied nearly 2,000 older Californians for five years. Those who attended religious services were 36 per cent less likely to die during this half-decade than those who didn’t. Even those who attended a place of worship irregularly — implying a less than ardent faith — did better than those who never attended.

Pretty impressive. But there’s more; so much more that it’s positively surreal. In 1990, the American Journal of Psychiatry discovered believers with broken hips were less depressed, had shorter hospital stays and could even walk further when they were discharged compared to their similarly broken-hipped and hospitalised, but comparatively heathen peers.

It’s not just hips. Scientists have revealed that believers recover from breast cancer quicker than non-believers; have better outcomes from coronary disease and rheumatoid arthritis; and are less likely to have children with meningitis.

Intriguing research in 2002 showed that believers have more success with IVF than non-believers. A 1999 study found that going to a religious service or saying a few prayers actively strengthened your immune system. These medical benefits accrue even if you adjust for the fact that believers are less likely to smoke, drink or take drugs.

And faith doesn’t just heal the body; it salves the mind, too. In 1998, the American Journal of Public Health found that depressed patients with a strong ‘intrinsic faith’ (a deep personal belief, not just a social inclination to go to a place of worship) recovered 70 per cent faster than those who did not have strong faith. Another study, in 2002, showed that prayer reduced ‘adverse outcomes in heart patients’.

But perhaps this is just an American thing? After all, those Bible-bashing Yanks are a bit credulous compared to us more sceptical Europeans, aren’t they?

Not so. In 2008, Professor Andrew Clark of the Paris School of Economics and Doctor Orsolya Lelkes of the European Centre for Social Welfare Policy and Research conducted a vast survey of Europeans. They found that religious believers, compared to non-believers, record less stress, are better able to cope with losing jobs and divorce, are less prone to suicide, report higher levels of self-esteem, enjoy greater ‘life purpose’ and report being more happy overall.

What is stunning about this research is that the team didn’t go looking for this effect — it came to them unexpectedly. ‘We originally started the research to work out why some European countries had more generous unemployment benefits than others,’ says Professor Clark. But as they went on, the pattern of beneficial faith presented itself. ‘Our analysis suggested religious people suffered less psychological harm from unemployment than the non-religious. Believers had higher levels of life satisfaction.’

So what’s going on? How does religion work this apparent magic? One of the latest surveys to suggest that religious people are happier than the non-religious was conducted by Professors Chaeyoon Lim and Robert Putnam, from Harvard, and published last year.

They discovered that many of the health benefits of religion materialise only if you go to church regularly and have good friends there. In other words, it’s the ‘organised’ part of organised religion that does a lot of the good stuff. Going to a friendly church, temple or mosque gives you a strong social network and a ready-made support group, which in turn gives you a more positive outlook on life — and offers vital help in times of need. The Harvard scientists were so startled by their findings that they considered altering their own religious behaviour.

As Professor Lim said: ‘I am not a religious person, but . . . I personally began to think about whether I should go to church. It would make my mum happy.’

But if the ‘congregation’ effect is one explanation for the good health of churchgoers, it’s not the only one. Other surveys have found that intrinsic faith is also important.

For instance, a study of nearly 4,000 older adults for the U.S. Journal of Gerontology revealed that atheists had a notably increased chance of dying over a six-year period than the faithful. Crucially, religious people lived longer than atheists even if they didn’t go regularly to a place of worship. This study clearly suggests there is a benefit in pure faith alone — perhaps this religiousness works by affording a greater sense of inner purpose and solace in grief.

This begs the question: Given all this vast evidence that religion is good for you, how come the atheists seem so set against it? They pride themselves on their rationality, yet so much of the empirical evidence indicates that God is good for you. Surely, then, it is the atheists, not the devout, who are acting irrationally?

All this will come as no surprise to many students of genetics and evolution, who have long speculated that religious faith might be hard- wired into the human mind. For instance, twin studies (research on identical siblings who are separated at birth) show that religion is a heritable characteristic: if one twin is religious, the other is likely to be a believer as well, even when raised by different parents.

Neurologists are making exciting progress in locating the areas of the brain, primarily the frontal cortex, ‘responsible’ for religious belief — parts of the brain that seem designed to accommodate faith. This research even has its own name: neurotheology.

Why might we be hard-wired to be religious? Precisely because religion makes us happier and healthier, and thus makes us have more children. In the purest of Darwinian terms, God isn’t just good for you, He’s good for your genes, too.

All of which means that, contrary to expectation, it is the atheists who are eccentric, flawed and maladaptive, and it’s the devout who are healthy, well-adjusted and normal.

Certainly, in purely evolutionary terms, atheism is a blind alley. Across the world, religious people have more children than non-religious (go forth and multiply!), while atheist societies are the ones with the lowest birth rates.

The Czech Republic is a classic example. It proclaims itself the most atheist country in Europe, if not the world; it also has a puny birthrate of 1.28 per woman, one of the lowest on the planet (so soon there won’t be any godless Czechs to proclaim their atheism).

The existence of atheism is therefore something of an anomaly. But then again, anomalies are not unknown in evolution. Think of the dodo or the flightless parrot, doomed to extinction. Are atheists similarly blighted? Are Richard Dawkins and his type destined to vanish off the face of the Earth — the victims of their own intellectual arrogance?

That’s not for me to say; it’s for you to ponder. All I do know is that reassessing the research has changed the way I think about faith. These days I go to church quite a lot, especially when I am travelling and researching my books. For instance, the other day I found myself in Cambridge — the home of Stephen Hawking — and took the opportunity to do some sightseeing of the city’s intellectual landmarks.

I strolled by the labs where Hawking does his brilliant work, popped into the pub where they announced the discovery of DNA and admired the library where Charles Darwin studied. As I did, I was in awe at the greatness of Man’s achievements. And then I went to Evensong at King’s College Chapel, and it was beautiful, sublime and uplifting. And I felt a very different kind of awe.

Sneer at faith all you like. Just don’t assume science is on your side.
