American adults consume on average about 15% of their calories from sugars added to foods during processing, with a whopping 37% of the added sugar consumed in sugar�sweetened beverages, suggests an analysis of data extending back about 25 years.Regularly drinking as little as one 12�ounce sugary soda a day may increase the risk of cardiovascular disease by about 30%�independent of total calories, obesity, or other risk factors, as per a study in JAMA Internal Medicine.Epidemiologic studies have linked high consumption of added sugar with an increased risk of type 2 diabetes, obesity, and hypertension.The American Heart Association recommends less than 100 calories a day (about 5% of total daily calories) for women and 150 calories a day (about 7.5% of total daily calories) for men from added sugars.The risk of CVD mortality becomes elevated once added sugar intake surpasses 15% of daily calories�equivalent to drinking one 20�ounce Mountain Dew soda in a 2000-calorie daily diet.The risk rises exponentially as sugar intake increases, peaking with a fourfold increased risk of CVD death for individuals who consume one�third or more of their daily calories in added sugar.
