Run, don't walk to get this set of CDs. I actually borrowed from the libary--regardless of how you obtain them, if you are at all interested in your health, these Cds are priceless. Dr. Hyman makes sense--and he backs up all of his facts with studies from either the New England Journal of Medicine or the JAMA. I love this guy! I tried listening to the cds by Kevin Trudeau, and while he has some of the same info he comes across as being a fanatic/conspiracy theorist (just my opinion).
Borrow or buy this set--you won't be disappointed with the amount of quality of info. I'm buying sets for my brother and mother.
