Sugary drinks - like soda, sports drinks, energy drinks, and sweetened coffees and teas - are the largest source of added sugar in the diet. Drinks with added sugar provide extra calories, but often no nutritional value, leading to unwanted weight gain. In addition, sugary drinks often replace healthy choices like low-fat milk, which is high in calcium and vitamin D. Children who drink sugary beverages almost double their risk of dental cavities and the average California teen drinks almost 39 pounds of sugar from sugary drinks each year.
