Dr. Dennis Burkitt Colon Cancer Western Nations Animal Products Plant Products Fiber
How Does Fiber Work To Prevent Cancer? • Moves food quickly through the digestive tract. • Pulls in water. • Water and fiber make carcinogens more diluted. • Binds to Bile acids.
Studies show that breast cancer is less common to those that have a diet high in fiber. Estrogens Normally secreted into the digestive tract. High levels are associated with breast cancer. Fiber and Breast Cancer
Whole grains, beans, peas, lentils, vegetables, and fruits are the best sources of fiber. • Foods should also be closest to their natural state, which is unrefined and unpeeled, to have the highest amount of fiber. • They take 26 nutrients out of whole wheat to make white flour, but they only add 4 back. http://www.pcrm.org/health/Preventive_Medicine/foods_for_cancer_prevention.html
