Vegetarians live longer

Vegetarians have a 14% lower chance of developing cancer than carnivores, according to a large study that links meat-eating to a heightened risk of the disease.

A team of researchers from Oxford University analysed data on more than 470,000 Britons and found that pescatarians had a 10% reduced risk. Compared with people who eat meat regularly – defined as more than five times a week – those who consumed small amounts had a 2% lower risk of developing cancer, the study found.

“In this large British cohort, being a low meat-eater, fish-eater or vegetarian was associated with a lower risk of all cancer sites when compared to regular meat-eaters,” the analysis found.

However, the authors, led by Cody Watling from Oxford’s population health cancer epidemiology unit, made clear that their findings did not conclusively prove regular meat-eating increased the risk of cancer. Smoking and body fat could also help explain the differences found, they said.

Their study of participants in the UK Biobank study also found that:

Low meat-eaters – who consume meat five or fewer times a week – had a 9% lower risk of developing bowel cancer than regular meat-eaters.

Vegetarian women were 18% less likely than those who ate meat regularly to develop postmenopausal breast cancer, though that may be due to their lower body mass index.

Vegetarian men have a 31% lower risk of prostate cancer while among male pescatarians it is 20% lower.

“The results … suggest that specific dietary behaviours such as low meat [and] vegetarian or pescatarian diets can have an impact on reducing the risk of certain cancers; in this case bowel, breast and prostate,” said Dr Giota Mitrou, director of research and innovation at World Cancer Research Fund International (WCRF), which co-funded the study with Cancer Research UK.


The results confirm WCRF’s longstanding advice that people should limit their intake of red and processed meat and eat more wholegrains, vegetables, fruit and pulses, she added.

The Oxford study authors said: “The lower risk of colorectal [bowel] cancer in low meat-eaters is consistent with previous evidence suggesting an adverse impact of meat intake. Vegetarian women’s lower risk of postmenopausal breast cancer is likely to be “largely” explained by their lower BMI.

“It is not clear whether the other differences observed for all cancers and for prostate cancer reflect any causal relationship or are due to other factors.”

While the researchers found that “being a low meat-eater, pescatarian or vegetarian was associated with a lower risk of all cancer”, they added that this “may be a result of dietary factors and/or non-dietary differences in lifestyle, such as smoking”. Their results are published on Thursday in the journal BMC Medicine.

Richard McIlwain, chief executive of the Vegetarian Society, said: “This study adds to a growing body of research reinforcing the positive, protective effects of a vegetarian diet.

“With cancer now affecting one in every two of us across the country, adopting a healthy vegetarian diet can clearly play a role in preventing this disease. Indeed, evidence from previous surveys suggests a balanced vegetarian diet can also reduce the risk of heart disease and diabetes, in addition to cancers.”

Watling and his colleagues are undertaking further research among vegetarians, pescatarians and vegans to examine more closely the relationship between diet and cancer risk.

Between 5% and 7% of Britons are thought to be vegetarian and 2-3% follow a vegan diet, according to surveys by YouGov.

Dr Julie Sharp, Cancer Research UK’s head of health and patient information, said that while reducing intake of processed meat has been proven to reduce the risk of bowel cancer “having some bacon or ham every now and then won’t do much harm”, adding: “If you are having a lot of meat a lot of the time then cutting down is a good idea, but a vegetarian diet doesn’t always mean someone is eating healthily.”

Where do drinking like a fish and smoking like a chimney factor in I wonder. They are both British national pastimes aren't they?

Used to be mine. I'll admit. But I haven't smoked for 20 years, and gave up drinking over a year ago.

It is safe to assume that vegetarians include a much higher percentage of people who care about their overall health compared to the wide variety of people who eat meat.

However numerous recent studies have shown there is no appreciable longevity benefit beyond 5 servings a day, 2 fruit and 3 vegetables. Each serving is a 1/2 cup, so that’s not really a ton of fruit/veg.

Seems to indicate that the diet choices are not as much at issue as an overall attitude to health that vegans/vegetarians generally hold.

That said, I’ve also read numerous reports of studies that indicate that the longevity benefit of vegetarianism or staying very lean is measured in the single digits of years. So is it that life is really a lot longer, or it just feels that way?

I remember listening to Dr Dean Edell on his once local daily radio program when he said (more than once) that people would live longer if they didn't eat so much.

Eating is overrated...

"Vegetarians live longer"

But why? Existentially speaking.

God loves them

True enuff, but after all, they spend ten precious years (cumulatively) worrying about shopping, struggling with cooking, arguing with carnivores, etc. just to add an extra one year of aged dependence-on-others at the far end.

Enjoy the young years - they don't make 'em any more!
