Fructose had no effect on LDL-C , non-HDL-C , apolipoprotein B , triglycerides , or HDL-C in isocaloric trials .
Conclusions Pooled analyses showed that fructose only had an adverse effect on established lipid targets when added to existing diets so as to provide excess calories ( + 21 % to 35 % energy ) .
When isocalorically exchanged for other carbohydrates , fructose had no adverse effects on blood lipids .
Background Debate over the role of fructose in mediating  cardiovascular  risk remains active .
To up date the evidence on the effect of fructose on established therapeutic lipid targets for cardiovascular disease ( low-density lipoprotein cholesterol [LDL]-C , apolipoprotein B , non-high-density lipoprotein cholesterol [ HDL-C ] ) , and metabolic syndrome ( triglycerides and HDL-C ) , we conducted a systematic review and meta- analysis of controlled feeding trials .
Blood lipids, lipoproteins, apoproteins, and uric acid in men fed diets containing fructose or high-amylose cornstarch.
Ten hyperinsulinemic and 11 nonhyperinsulinemic men consumed for 5 wk each in a cross-over design a diet , similar to one currently consumed in the United States , with 20 % of the kilocalories from either fructose or high-amylose cornstarch to determine the effects of the two diets on various blood metabolites considered to be risk factors associated with heart disease . In the hyperinsulinemic men the intake of fructose as compared with cornstarch significantly increased total triglycerides and their lipoprotein distribution ; total and very-low-density lipoprotein cholesterol ; apoproteins B-100 , C-II , C-III ; and uric acid . In the nonhyperinsulinemic men  total triglycerides , total and low-density lipoprotein cholesterol and uric acid were significantly greater after the consumption of fructose than after cornstarch . The results indicate that in a diet high in saturated fatty acids and cholesterol , fructose increases the levels of risk factors associated with heart disease , especially in hyperinsulinemic men
