Medscape reports on a paper presented at the August 29 Union for International cancer Control World Cancer Congress 2012 by Richard Beliveau, Ph D, from the University of Montreal, University of Quebec at Montreal, and McGill University in Quebec. He stated that not all fruits and vegetables protect against cancer, but rather specific fruits and vegetables protect against specific cancers. He mentioned turmeric the spice as being a powerful anti-inflammatory that could prevent cancer from developing. Inflammation is a risk factor for cancer, as seen in inflammatory bowel disease or with infections such as H. pylori. He highlighted epigallocatechin gallate, which is found in green tea. It targets tumor invasion and metastasis, as well as prevents the formation of blood vessels. Resveratrol from grapes also has anti-tumor effects as does broccoli. Tomatoes have been found to reduce the risk of prostate cancer, and leafy green vegetables reduce the risk for pancreatic cancer.
He also mentioned obesity, which is associated with cancers. He pointed out that people over 40 are tumor carriers, but the tumors start in adolescence. We can either feed those tumors or prevent those tumors.
The 5 "golden rules" of chronic disease prevention also apply to cancer: (1) don't smoke; (2) maintain a BMI between 21 and 23 kg/m2; (3) eat an abundance of plant products (fruits, vegetables, grains); (4) exercise at least 30 minutes a day; (5) stay away from industrially prepared (junk) food. I would probably add in the importance of 6-8 hours of sleep at night, healthy social relationships, and ways to de-stress (meditation, listening to quiet music, reading).
