stimp, All I can say is that pre-med doesn't prepare you for much, but a major in chemistry sure would help. Of course, Biochemistry is mandatory in understanding enzymes and the role that the vitamins, minerals, hormones, and other precursors found in healthy foods play in rebuilding the body, preventing disease, and enhancing the health of the body and MIND! And it is not psychological! The results speak for themself!
I don't know when you were in pre-med or how far you went in those studies, but I would hope it was a GOOD background in the SCIENCES. If it was more then 5-8 years ago, then you would not have learned about the important NEUTRICEUTICALS and PHYTOCHEMICALS contained in properly grown fresh foods, that are absolutely essential for good health, overcoming disease, and repairing the body.

I also got a chuckle out of the favorite medical rationalization for the void in their knowledge of the Nutritional Sciences by merely stating, that supplements don't work. Most DRS use this, when they are giving you prescriptions for drugs (foreign chemicals) with side-effects, and must be excreted from the body, since they are toxic to the body and do nothing to rebuild it.

You really should familiarize yourself with all the research and knowledge of Phytochemicals coming out of reputable Universities with leading medical schoold in the U.S. and the rest of the World.
The Internet is loaded with current information, so it should not be TOO difficult to become more informed should you desire to do so.
