I found the author to be sensationalist at best. Some of his statistics seemed skewed and begged a lot more analysis than he gave them. I appreciated his long bibliography and various footnotes, but I don't think he used his information well. I expected a lot more. Nonetheless, I agree with his final analysis that American doctors/patients are too quick to pop a pill. There's a lot to be said for natural light exposure, exercise and a change in diet.
