Chances are you already know that eating too much sugar isn’t good for you. Yet you’re probably still overdoing it: Americans average about 20 teaspoons of added sugars per day, compared to the recommended 6 teaspoons for women and 9 teaspoons for men. (That doesn't include sugar found naturally in foods like fruits and milk.) An abundance of added sugar may cause your liver to become resistant to insulin, an important hormone that helps turn sugar in your bloodstream into energy. This means your body isn’t able to control your blood sugar levels as well, which can lead to type Ⅱ diabetes.
