Gatorade was first developed to prevent dehydration among elite athletes during intense and prolonged training sessions in severe heat. Few of us ever require that level of hydration. Yet, sports drinks have been marketed so well, many of us reach for them instead of water for refreshment more often than rehydration. These drinks are loaded with sugar and are extremely acidic. This is an ideal combination for promoting tooth decay, as the bacteria in our mouths turn those sugars into even more acid that eat away at healthy tooth structure. This is how cavities are born. When you get thirsty this summer, drink natural water. It will refresh, rehydrate, and reduce plastic bottle waste.
