Yes, you are right in saying that some of us don't have a very high opinion of Dr. Oz. If you ate all of the things he claims will add months or years to your life it probably adds up to half a century. More likely, you will just get to be obese. No doubt eating some things and avoiding others will do your body good but as a retired scientist, I ask, "Where is the proof?" We have an entire industry of nutritional supplements which Congress in its infinite wisdom exempted from the pure food and drug act. If it is classified a "food" or "nutritional supplement" instead of a "medicine" almost any claim can be made. In many cases you do get just a bit lighter as the supplement seller lightens your wallet considerably. The only time these things come off the market is if they actually kill someone. Just being worthless doesn't count.
