Meat Kills

And I quote:

Men who eat a lot of red meat and processed meats may have a higher risk of developing prostate cancer than those who limit such foods, a large study of U.S. men suggests.

Researchers at the National Cancer Institute found that among more than 175,000 men they followed for nine years, those who ate the most red and processed meats had heightened risks of developing any stage of prostate cancer, or advanced cancer in particular.

Overall, the researchers found, the 20 percent of men with the highest intakes of red meat, which in this study included beef and pork, were 12 percent more likely than those who consumed the least to develop prostate cancer. That's after a range of other factors, like smoking, exercise habits and education, were taken into account.

There was a stronger connection to advanced prostate cancer -- with that risk being almost one-third higher among those who ate the most red meat versus those who ate the least.

When it came to cooking methods, the only one that was linked to prostate cancer was grilling/barbecuing, Sinha's team found.

The finding is in line with the theory that meats cooked at high temperatures may be particularly linked to cancer because the cooking process produces certain chemicals -- including polycyclic aromatic hydrocarbons (PAHs) and heterocyclic amines -- that are known to cause cancer in animals.
