Can green tea help with diabetes?

Gary Scheiner

There is no scientific proof that green tea is useful in treating or preventing diabetes. However, consuming green tea (which is virtually calorie-free) in place of sugar-sweetened beverages can help with weight loss and glucose tolerance.

Some research suggests green tea may be helpful in reducing blood glucose and the risk of type 2 diabetes. It has been studied in mice and humans, showing some antihyperglycemic effects. It is thought to act on blood glucose levels throughout the body, but specifically by promoting the action of insulin in the uptake of glucose in muscles and fat cells.

Some research suggests that green tea also helps oral health by improving the health of gums. The antioxidant catechin present in green tea is thought to be the active promoter of healthy gums. Catechin is a mild anti-inflammatory. Much more research is needed to establish the benefits in vivo.
