Ask the doctor: Drinking green tea may lower health risks
Q. I keep hearing that green tea is good for warding off cancer. Should I become a regular tea drinker to reap the benefits?
A. There is moderately strong evidence that regular green tea drinkers have lower rates of several cancers—particularly cancer of the colon, prostate, breast, lung, and skin. Green tea also may have other health benefits: it may increase metabolism and thereby enhance weight loss, and it may protect against thinning of bones.
