Quitting Sugar Cuts Heart Disease Risk in Obese Children

A new study by Dr Robert Lustig shows obese children significantly reduced their risk of heart disease after cutting out fructose.

Atherosclerosis: Short-term isocaloric fructose restriction lowers apoC-III levels and yields less atherogenic lipoprotein profiles in children with obesity and metabolic syndrome

The conditions were tightly controlled so that only fructose consumption was affected. The children were given the same amounts of calories, fat, protein and carbohydrates as their typical diets.

Obese children with MetS (n = 37) consumed a diet that matched self-reported macronutrient composition for nine days, with the exception that dietary fructose was reduced from 11.7 ± 4.0% to 3.8 ± 0.5% of daily calories and substituted with glucose (in starch). Participants underwent fasting biochemical analyses on Days 0 and 10. HDL and LDL subclasses were analyzed using the Lipoprint HDL and LDL subfraction analysis systems from Quantimetrix.

Isocaloric fructose restriction for 9 days improved lipoprotein markers of CVD risk in children with obesity and MetS. The most dramatic reduction was seen for apoC-III, which has been associated with atherogenic hypertriglyceridemia.
