Too Much Sugar is Bad for Your Heart

The Dietary Guidelines for Americans 2010 recommends an upper limit of 25 percent or less of daily calories consumed as added sugar. Researchers at the Davis-based University of California examined what happened when young, overweight and normal weight adults consumed fructose, high fructose corn syrup or glucose at the 25 percent upper limit. Results showed that, within two weeks, participants who had consumed fructose or high fructose corn syrup exhibited high levels of LDL cholesterol, triglycerides and apolipoprotein-B (a plaque-forming protein that  causes vascular disease.), but not those consuming glucose.  Kimber Stanhope, head of the research team, said: “Our findings demonstrate that several factors associated with an elevated risk for cardiovascular disease were increased in individuals consuming 25 percent of their calories as fructose or high fructose corn syrup, but consumption of glucose did not have this effect.” He concluded that the findings suggest that sugar consumption may promote heart disease.
