Not just a little tea, though. You need to drink four cups a day or more, at least according to a new German study.
'Tea consumption may lower the risk of type 2 diabetes by influencing glucose digestion, glucose uptake, and by protecting beta-cells from free-radical damage. This beneficial effect may be due to the polyphenols present in tea.’More research is needed, and it is important to distinguish between causation and correlation. The fact that heavy tea drinkers develop diabetes less often may not be due to the tea drinking. It could be that crumpets, a British tea time snack, is a great undiscovered cure for diabetes!
Or it could simply be that heavy tea drinkers don't consume as much sugar as folks who drink soda pop or sugary lattés.
