Many health problems, like diabetes and cancer, are linked to what you drink. Not surprisingly, water is best drink bet. But Americans have increased their consumption of sweetened drinks like soda and juices a lot in the past thirty years. "About 21 percent of calories consumed by Americans over the age of 2 come from beverages, predominantly soft drinks and fruit drinks with added sugars." And even diet sodas don't get you off the hook, because of the lack of long-term safety data for artificial sweeteners. Wine, coffee, and milk are all recommended over sweet drinks.
