A literature analysis supported links between  sugar  intake and both total energy intake and body weight gain , and between sugar intake and blood triglycerides independently of total energy intake .
The effects of sugar on blood triglycerides were shown to be mediated by the fructose component of sucrose and were observed with an intake of fructose > 50 g/day .
In addition , prospect i ve cohort studies showed associations between sugar intake and the risk of diabetes/insulin resistance , cardiovascular diseases , NAFLD , and hyperuricemia .
Effect of Eucaloric High- and Low-Sucrose Diets With Identical Macronutrient Profile on Insulin Resistance and Vascular Risk
The long-term impact of dietary carbohydrate type , in particular sucrose , on insulin resistance and the development of diabetes and atherosclerosis is not established . Current guidelines for the healthy population advise restriction of sucrose intake . We investigated the effect of high- versus low-sucrose diet ( 25 vs. 10 % , respectively , of total energy intake ) in 13 healthy subjects aged 33 ± 3 years ( mean ± SE ) , BMI 26.6 ± 0.9 kg/m2 , in a r and omized crossover design with sequential 6-week dietary interventions separated by a 4-week washout . Weight maintenance , eucaloric diets with identical macronutrient profiles and fiber content were design ed . All food was weighed and distributed . Insulin action was assessed using a two-step euglycemic clamp ;  glycemic profiles were assessed by the continuous glucose monitoring system and vascular compliance by pulse-wave analysis . There was no change in weight across the study . Peripheral glucose uptake and suppression of endogenous glucose production were similar after each diet . Glycemic profiles and measures of vascular compliance did not change . A rise in total and LDL cholesterol was observed . In this study , a high-sucrose intake as part of an eucaloric , weight-maintaining diet had no detrimental effect on insulin sensitivity , glycemic profiles , or measures of vascular compliance in healthy nondiabetic subjects
