A very interesting study on the effects of black tea on blood glucose levels was just published in the Journal of the American College of Nutrition.

In said study, British researchers revealed that drinking 12 ounces of the beverage after eating a high-carbohydrate meal can reduce blood sugar levels. Test subjects that consumed food that contained high-glycemic indexed carbs and then drank black tea witnessed 40 percent greater decrease in their blood sugar levels than test subjects that who didn't drink the tea after the meal.

Amazingly, this blood sugar stabilization extended over a two-hour period after the meal was finished. Researchers posit that active ingredients in the tea cause the secretion of more insulin, a hormone that naturally lowers blood sugar levels.
