In 35 years of medical research, conducted at the nonprofit Preventive Medicine Research Institute, which I founded, we have seen that patients who ate mostly plant-based meals, with dishes like black bean vegetarian chili and whole wheat penne pasta with roasted vegetables, achieved reversal of even severe coronary artery disease. They also engaged in moderate exercise and stress-management techniques, and participated in a support group. The program also led to improved blood flow and significantly less inflammation which matters because chronic inflammation is an underlying cause of heart disease and many forms of cancer. We found that this program may also slow, stop or reverse the progression of early stage prostate cancer, as well as reverse the progression of Type 2 diabetes.
Also, we found that it changed gene expression in over 500 genes in just three months, “turning on” genes that protect against disease and “turning off” genes that promote breast cancer, prostate cancer, inflammation and oxidative stress.
