Jonny Bowden's
The 150 Healthiest Foods On Earth, and Michael Pollan's
The Omnivore's Dilemma and
In Defense Of Food are a couple of favorites. I also like to read these websites:
Natural News Mercola.com, and
The World's Healthiest Foods blog.
Also, there is a new magazine called
Clean Eating. It's pretty good.
I'm going to check out some of the other food books you mentioned.
