FDA Flashes Red Light on Green Tea Heart Benefits: "Green tea does not lower heart-disease risk, according to the FDA. The agency rejected a request for a 'qualified health claim' that would have permitted labeling for cardiovascular benefits from the consumption of green tea, either as a drink or a dietary supplement. In its letter of denial, the FDA concluded that the studies presented to support the claim were flawed in design, inconclusive, or found no evidence of a beneficial relationship."
