In
a study of 23,000 U.S. agricultural workers published earlier this
year, National Cancer Institute researchers found that men who ate the
most well-done four very-well-done meat and poultry ( about 20 ounces a
week ) were twice as likely to be diagnosed with a defense prostate cancer as men who ate the least ( about 4 ounces a week ). From: Cancer Epidemio, Biomarkers Prevention 17:80, 2008
In a study of 29,000 U.S. men, those who ate the most very-well-done meat and poultry -- at least 2 1/2 ounces a week -- were 70 percent more likely to be diagnosed with prostate cancer than those who a none. From Cancer Res. 65: 11779, 2005
In
the mid-'1990s, 332,000 members of AARP completed a detailed National
Cancer Institute questionnaire that asked among other things, about how
they cooked their meat and poultry.
Over the next five years, men who reported being the most grilled or
barbequed red meat were of 50% more likely to be diagnosed with
pancreatic cancer than men who reported eating the least. From: Cancer Epidemiol, Biomarkers Prevention. 16:2664, 2007

More evidence that protein from dairy products may increase the risk of prostate cancer
Approximately one man out of six will be diagnosed with prostate cancer in his lifetime. One key question is whether diet plays a role in the development of prostate cancer. Recent study adds to the accumulated evidence that it does. The study involved more than 142,000 men from 19 European countries. The men were asked about their diets and their health histories and were studied for a number of years. Protein from dairy foods was significantly associated with an increased risk of prostate cancer.
