Query: Excellent read

This is a easy read, it reinforces a lot of things I already believed in, namely that diet controls a good portion of our health. It takes that concept further than most doctors would, not only preventing the big killers (Heart attack, heart disease, diabetes, etc.) but also the common flu, allergies, and other childhood illnesses. He has a no-holds barred attitude about society's norms and morales, and it's a refreshing but not overly paranoid view of the food world we live in.I'm already a vegan but it gave me some great ideas on some things I should be adding to my children's diet as well as my own. What's good for the goose is good for the gander.
