I think fad diets come and go. But eating whole foods in my opinion should be the best conventional wisdom diet. It has been eaten since the beginning of time before processing came out. If it becomes CW then everyone would be a whole hell of a lot healthier. But I do not think it will become CW recommended by the USDA since there are no profits to be made from whole foods. Big pharma won't let it happen either. So I do not think it will become mainstream CW although it should have always been the CW diet. (At least it has been for many traditional cultures)

People say I am on a "crazy" diet. What is so crazy about eating veggies, fruits, seafood and organ meats? Just because I don't eat whole wheat and processed food doesn't make my diet "crazy". Maybe everyone else with a SAD are the "crazy" ones for putting that junk in their system.
