LOS ANGELES — University of California scientists have connected the effects of drinking black tea to weight loss in mice. <br /> <br />The study was published in the European Journal of Nutrition. <br /> <br />Over a period of 4 weeks, three groups of mice were fed high-fat, high-sugar diets and compared to a group was given a low-fat, high-sugar diet. Two of the high-fat, high-sugar groups' diets were supplemented with black and green tea." <br /> <br />After the 4 weeks scientists found that weight among the mice who consumed tea had lowered to the same level as those on a low-fat, high-sugar diet. <br /> <br />Analysis of intestinal samples revealed both black and green tea lessened bacteria associated with obesity and increased bacteria associated with lean muscle mass. <br /> <br />Green tea was also shown to be easily absorbed by the liver, while black tea was found to stay in the intestine and help build bacteria that help with metabolism.
