Black Tea May Fight Diabetes

In a study of the polysaccharide levels of green, oolong and black teas, researchers found the polysaccharides in black tea had the most glucose-inhibiting properties. Polysaccharides, a type of carbohydrate that includes starch and cellulose, may benefit people with diabetes because they help retard absorption of glucose. The study, published in the Journal of Food Science, also showed black tea polysaccharides have the highest scavenging effect on free radicals.
