Huge study claims red meat boosts risk of dying young

Epidemiological nonsense. Food fads are probably much more common among middle class people and they are healthier anyway. So all we are seeing here is the usual class effect, not an effect of meat eating per se

Eating a portion of processed red meat daily can boost a person's risk of dying young by up to 20 per cent, says a long-running US study of more than 120,000 people.

While the research by Harvard University experts offers more evidence that eating red meat increases the risk of heart disease and cancer, it also counsels that substituting fish and poultry may lower early death risk.

"This study provides clear evidence that regular consumption of red meat, especially processed meat, contributes substantially to premature death," said Frank Hu, senior author of the study in the Archives of Internal Medicine.

Researchers gleaned their data from a study of 37,698 men who were followed for 22 years and 83,644 women who were tracked for 28 years.

Subjects answered surveys about their eating habits every four years. Those who ate a card-deck-sized serving of unprocessed red meat each day on average saw a 13 per cent higher risk of dying than those who did not eat red meat as frequently. And if the red meat was processed, like in a hot dog or two slices of bacon, that risk jumped to 20 per cent.

However, substituting nuts for red meat lowered total mortality risk by 19 per cent, while poultry or whole grains lowered the risk by 14 per cent and fish did so by 7 per cent.

The authors said between 7 and 9 per cent of all deaths in the study "could be prevented if all the participants consumed fewer than 0.5 servings per day of total red meat".

Processed red meat has been shown to contain ingredients such as saturated fat, sodium, nitrites and some carcinogens that are linked to many chronic ailments including heart disease and cancer.

"More than 75 per cent of the $US2.6 trillion ($2.5 trillion) in annual US health care costs are from chronic disease," said an accompanying commentary by Dean Ornish, a physician and dietary expert at the University of California, San Francisco.

"Eating less red meat is likely to reduce morbidity from these illnesses, thereby reducing health care costs."

One soft drink a day raises 'heart attack danger' by 20 per cent according to U.S study

This rubbish is from the same database as in the article above so the same comments apply

Drinking one sugar-laden soft drink every day could dramatically increase the odds of having a heart attack.

A study of more than 40,000 men suggested that a daily sugar-sweetened drink raised the chances of having a heart attack – including a deadly one – by 20 per cent.

In contrast, diet varieties that use artificial sweeteners were given a clean bill of health by the study’s authors.

Researcher Lawrence de Koning said the body may compensate for the sugar rush of soft drinks by making its own supply of fats, and some of these will be bad for the heart.

Tests on blood samples showed those who drank the sugary beverages tended to have higher levels of dangerous blood fats and of proteins linked to heart disease. Levels of ‘good’ cholesterol were lower, the journal Circulation reported.

The study also found that the more sugary drinks someone had, including still fruit squashes to which sugar is added during manufacturing, the more the risk rose.

Importantly, the link stood when other factors such as smoking, weight, alcohol and exercise were taken into account.

The U.S. research team made their link after analysing information provided by men who were asked every two years between 1986 and 2008 to provide detailed information about their diet.

Tallying the information showed that compared to never drinking sugary soft drinks, having 350ml a day – a standard can contains 330ml – raised the risk of a heart attack by 20 per cent.

Previous research has linked sugary drinks with diabetes and weight gain.

Dr de Koning, of Harvard University, said that although his study did not link diet soft drinks with heart problems, ‘better choices’ are available.

He said: ‘Water, coffee and tea are probably the best choices, after that would be low-fat milk. It is not clear whether fruit juice is a good replacement. There is a lot of sugar in it but it does have added benefits such as vitamins and fibre.’ Tea and coffee should be taken without sugar, he added.
