Kick Those Genes into Gear Through Healthy Living

A study led by UCSF doctor Dean Ornish found that lifestyle changes -- instead of invasive treatment -- can reverse cancer. In 30 men with early-stage prostate cancer who chose to enroll in his program, which included a "low-fat, whole-food, plant-based diet, stress management, moderate exercise and plenty of 'psychosocial group support,'" Ornish found that the expression levels of more than 500 genes were changed. Oncogenes were turned off, and genes that protect against cancer, including one for a protein that helps the immune system recognize tumor cells, were switched on, says this article in The Economist.
