We Eat Four Times As Much Sugar As We Should! According to a 2009 study in Circulation, annual sugar intake has increased 19% from 1970 to 2005. In 2009, the American Heart Association (AHA) reported Americans were ingesting an average of 111 grams of sugar per day which is the equivalent of about 450 calories per day! The AHA set a limit of suggested sugar intake of 30 grams per day max, which is equivalent to only 120 calories per day or about one quarter of average current consumption.
