Between 1970 and 2005, our intaKe of added sugars—cane and beet sugar, high-fructose corn syrup, dextrose, and other sweeteners—jumped 20 percent. We now consume 22 to 30 teaspoons a day. That's 350 to 475 empty calories that most people can't afford. A growing body of research suggests that added sugars or su gar-sweetened beverages boost the risk of disease. "We know that sugars contribute to obesity, which in turn increases the risk of cardiovascular disease and type 2 diabetes," says Linda Van Horn, who chairs the American Heart Association's Nutrition Committee. A new report from the heart association urges Americans to slash their sugar intake. The new targets: only 100 calories a day of added sugars for women and 150 calories a day for men. That's not much. Continued on p. 3. -*::> -^.
