JAMA studies

On the January 8th issue of the Journal of the American Medical Association (JAMA), 3 studies were done to find out about the correlation between cancer and heart disease rates of women who had diets that were high in fruits and vegetables and low in fat versus those that had diets higher in fat and less in fruits and vegetables. These 3 studies concluded that there were no difference between rates of breast and colorectal cancer and no difference between rates of heart disease between either groups of women.

If we take earlier studies showing high correlations between consumption of meat and higher risks of colorectal cancer with this most recent study regarding vegetables, it seems to support that, in regards to colorectal cancer at least, it's not eating more vegetable that helps, but rather reducing the amount of red meat that we eat that counts.

Even so, it's still a good idea to eat your vegetables, as there has been numerous studies showing that vegetables can decrease chances of certain cancer, specifically pancreatic cancer and lung cancer.

Here's a link to a study done by researchers at the University of California, San Fransisco, on the effects of vegetable consumption and pancreatic cancer:
