The Plant Paradox: The Hidden Dangers in "Healthy" Foods That Cause Disease and Weight Gain by Steven R. Gundry, MD
I picked this up and actually started reading it a couple of years ago when several celebrities were touting Dr. Gundry's techniques. I'm interested in different perspectives on how food affects the body so it was a natural fit for my reading list.
I am definitely not a biology person, but I know that different foods affect different people differently and that no one "diet" will work for everyone because of that.
