Penciling in a tea time may help keep your waistline in check. When Penn State scientists fed mice a high-glycemic meal along with an antioxidant extract from green tea, the resulting spike in blood sugar was only half as high as what was observed in the mice who were not given the extract. What does this mean for you? “[Green tea] should, in essence, lower the glycemic index of starchy foods,” said Josh Lambert, Ph.D., the study’s head researcher. High-glycemic foods, like simple carbs, disrupt your ability to burn fat, so by lowering the glycemic index of food you eat, your body is able to burn fat for longer. Downing 1.5 cups of green tea will do the trick—try it with your morning bagel or a Chinese dinner.
