Six cancer-preventing dietary guidelines, from the Physicians Committee for Responsible Medicine, emphasize a diet rich in plant foods, and warn about the links between cancer and alcohol, red and processed meats, dairy, and meats cooked at high temperature, according to the June 30, 2014 issue of the Journal of the American College of Nutrition. The guidelines are based on the principle that diet changes are justified when evidence is substantial, even if not conclusive.
- Dairy products. Every 35 grams per day of dairy protein may increase risk of prostate cancer by 32 percent.
- Alcohol. Limit or avoid to reduce risk of breast and colon cancer.
- Red and processed meat. A daily serving increases risk of colorectal cancer by 21 percent.
- Grilled, broiled, and fried meats. Avoid these to reduce risk of certain cancers.
- Soy products. Consume whole soy foods like tofu, edamame, and tempeh each day to help reduce breast cancer.
- Fruits and vegetables. Eat more to help reduce risk of several common cancers.
