Well, the material and claims in the original book are very well referenced. And those studies are beyond doubt valid scientific research. I don't know about those other works, but I concentrate on this issue.
What comes to benefits of coffee, teas and coffee themselves. For that there is a long explanation for some benefits, or rather the elimination of their validity. Once more referenced studies. I know that some chemicals in coffee and tea can have positive health benefits, but I'm not counting caffeine as one of them, and they can be obtained from non-caffeine sources as well. Nice answer anyway.
