I've grown to love the taste of green tea—jasmine pearls, sencha, genmaicha—almost as much as I love green tea's health benefits for heart, brain, and waistline. But I'm happy to have an excuse to add Earl Grey back into to my tea stash. Weight maintenance benefits of green tea and its polyphenols—notably epigallocatechin gallate (EGCG)—have been widely recognized in recent years. Now, new research published in Nutrition suggests that although it contains significantly less EGCG black tea may offer similar protection against weight gain. Scientists fed mice high-fat diets either with or without black tea extracts. Those given black tea showed significantly less weight gain and blood triglyceride levels. The scientists speculate that black tea's primary polyphenols, theaflavins and thearubigins, may be responsible for black tea's weight stabilizing qualities.
