Green Tea, Black Coffee

Coffee or tea? There's a growing body of research to suggest that both are probably good for you.

We've heard a lot about the health benefits of tea, especially green tea. It is high in polyphenols--compounds with strong antioxidant activity that in test-tube and animal models show anticancer and heart-protective effects. Good clinical studies are few, however, and although I and other physicians tell our patients to drink green tea, there hasn't been any definitive proof of the value of that advice.
