Nutrigenomics and How to use Food, and relaxation to become healthy is the topic of the video below (with Dr Mark Hyman). Nutrigenomics is relatively new science but has a lot of promise. It is the study of which foods have what epigenetic effects on our DNA. It could be a bible of what to eat to avoid diseases or what to eat to cure a disease. If used wrong it can be input to drug companies on new drugs to make.
