Fructose-sweetened beverages are more important for the deposition of lipids in the wall of the arteries in obese people than those containing glucose.
Kimber Stanhope and colleagues at the University of California, Davis, compared the effect of 10 weeks of consumption of the two drinks by overweight people against a diet of 30% fat and 55% complex carbohydrates. Triglycerides and LDL-cholesterol were found to be elevated in participants consuming fructose, in contrast to others in whom a decrease in the first type and a stabilization of the second type of serum lipids were observed.
These data were also presented at the annual meeting of the American Diabetes Association in Chicago. According to the study authors, patients at risk for metabolic syndrome and cardiovascular disease should limit fructose-sweetened products.
