Subgroup analyses showed the most marked relation between sugar intakes and lipids in studies in which efforts were made to ensure an energy balance and when no difference in weight change was reported .
CONCLUSIONS Dietary sugars  influence blood pressure and serum lipids .
The relation is independent of effects of  sugars on body weight .
BACKGROUND Dietary sugars have been suggested as a cause of obesity , several chronic diseases , and a range of cardiometabolic risk factors , but there is no convincing evidence of a causal relation between sugars and risk factors other than body weight .
OBJECTIVE We conducted a systematic review and meta- analysis of r and omized controlled trials that examined effects of the modification of dietary free sugars on blood pressure and lipids .
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
