For what it's worth, my favorite book on eating healthy is called,
"Your health, your choice" by Ted M. Morter, M.D.
He is a physician who wondered why some of his patients got better, and why some did not. He did extensive research in hopes to better serve his patients, and the book is what he found.
It's jam packed with info on food and how your body handles certain categories of foods, such as how easily (or not so easily) something is digested. And what the body requires to digest certain foods.
And it easily explains the causes of osteoporosis, for instance, and other common ailments, and how they're just not necessary.
thought some of you might enjoy it!
