Red and Processed Meat Increases Risk of Prostate Cancer
Meat consumption increases the risk of prostate cancer, according to a recent study looking at more than 175,000 men as part of the NIH-AARP Diet and Health Study. The men who consumed the most red meat had a 30 percent increased risk of cancer, compared with those who consumed the least. Processed red meat was associated with a 10 percent increased risk of prostate cancer with every 10 grams (about one-third of an ounce) of increased intake. Researchers also investigated cooking method and content of heme iron and nitrites and nitrates for the various types of meat consumed. Heme iron intake, nitrite and nitrate consumption, and grilling and barbecuing all were associated with higher risk.
