This is Dr. Oz's recipe for a powerful metabolism-boosting drink. According to Dr. Oz, green tea is shown to boost metabolism 12% by drinking just one cup; tangerine contains a chemical composition that increases sensitivity to insulin and stimulates genes that help to burn fat, and mint is a calorie-free flavor enhancer. Drink 1 pitcher daily for maximum metabolism-boosting results. I believe this can't hurt and can only promote good health. 5/2/13 Again, the recipe is meant to be a metabolism booster and because it's not loaded with sugar or sugar substitutes it will not be a sweetened drink. It's aim is health benefits and hoped it will judged as such.
