Me! Me! Our library has it and I read it on recommendation of a friend. I enjoyed it, but it's not one I'd buy to reference it. I don't think you'd be surprised by much (anything?) in it.

Basically, he recommends tracing your family tree and listing any health issues for each person (allergies, anemia, cancer, cause of death, etc.). Also any distinguishing characteristics (sometimes the receding hairline gene goes along with the allergy to XYZ, so if your dad didn't have the receding hairline, then he AND you won't have the allergy). People have come him not feeling well after having been to many doctors and using this type of family tree, he's diagnosed various allergies (lots of grain allergies and dairy allergies, but eggs and others, too). He also talked about certain diseases going together. I remember the section on Alzheimers and Down's syndrome, and the woman in my church with Alzheimers and her son with Downs. Can't remember all of them.

He also talked about genes, dominant, recessive, X-related, etc. If you're wondering... the *only* "disease" associated with the Y chromosome is hairy ears. Mr. Kay's dad has hairy ears, so Mr. Kay and Tom are DOOMED!

You already know the amazing changes that can occur by going GF. The same applies if you have allergies or intolerances to other foods and get those out of your diet. So, it was enjoyable, but it didn't strike me as one I'd refer to again. I can always go back to the library for it.
