Green Tea

Literally hundreds of studies have been carried out to document the health benefits of catechins, the group of antioxidants concentrated in the leaves of tea plants. Among the most startling studies was one published by the American Medical Association in 2006. The study followed more than 40,000 Japanese adults for a decade, and at the 7-year follow-up, those who had been drinking five or more cups of tea per day were 26 percent less likely to die of any cause compared with those who averaged less than a cup. Looking for more immediate results? Another Japanese study broke participants into two groups, only one of which was put on a catechin-rich green-tea diet. At the end of 12 weeks, the green-tea group had achieved significantly smaller body weights and waistlines than those in the control group. Why? Because researchers believe that catechins are effective at boosting metabolism.
