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 lipid distribution of hyperinsulinemic men consuming three levels of fructose.
Twelve carbohydrate-sensitive men selected due to their abnormally high insulin responses to a sucrose load and 12 men with normal insulin responses were fed diets containing 0 , 7.5 , and 15 % fructose for 5 wk each in a cross-over design . The diets contained 43 % total carbohydrate , 42 % fat , and 15 % protein . Initial fasting total cholesterol and low-density lipoprotein cholesterol were higher in the hyperinsulinemic men than in the controls . Diastolic blood pressure was not affected by diet , but systolic blood pressure was slightly higher after the men consumed the 0 % fructose diet . Free fatty acids were not different . Total plasma cholesterol and low-density lipoprotein cholesterol were higher after the men consumed 7.5 and 15 % fructose than when they consumed the 0 % fructose diet . Plasma triglyceride increased significantly as fructose in the diets of the hyperinsulinemics increased , but was not affected in the controls . These changes in blood lipids are associated with heart disease
