Regular black tea is turning out to be just as healthful as green tea. The evidence for tea's health effects comes mainly from lab studies, though some human studies point to possible benefits in preventing heart disease and cancer.

Green and black tea fight diabetes
Black tea is as good as green tea in reducing sugar levels and inhibiting cataracts in diabetic mice, researchers said Tuesday. The study by the University of Scranton in Pennsylvania found both teas reduced glucose levels and other diabetic complications, such as cataracts, during the three-month test on rats. "Most people, scientists included, believe that green tea has more health benefits than black tea," said lead author Joe Vinson. of the research to be published in the American Chemical Society's Journal of Agricultural and Food Chemistry. The finding that green and black teas are beneficial suggests the drinks could be simple and inexpensive ways for humans to fight diabetes, he said. Vinson's earlier work showed both teas equally inhibited atherosclerosis, a major risk for people suffering from heart disease as plaque builds up on arterial walls.
