There was interaction by food source , with specific food sources showing beneficial effects ( fruit and fruit juice ) or harmful effects ( sweetened milk and mixed sources ) in substitution studies and harmful effects ( sugars‐sweetened beverages and fruit juice ) in addition studies on at least one outcome .
Conclusions Energy control and food source appear to mediate the effect of fructose‐containing sugars on glycaemic control .
Although most food sources of these sugars ( especially fruit ) do not have a harmful effect in energy matched substitutions with other macronutrients , several food sources of fructose‐containing sugars ( especially sugars‐sweetened beverages ) adding excess energy to diets have harmful effects .
Objective To assess the effect of different food sources of fructose‐containing sugars  on glycaemic control at different levels of energy control .
Energy compensation following consumption of sugar-reduced products: a randomized controlled trial
Purpose Consumption of sugar-reformulated products ( commercially available foods and beverages that have been reduced in sugar content through reformulation ) is a potential strategy for lowering sugar intake at a population level . The impact of sugar-reformulated products on body weight , energy balance ( EB ) dynamics and cardiovascular disease risk indicators has yet to be established . The REFORMulated foods ( REFORM ) study examined the impact of an 8-week sugar-reformulated product exchange on body weight , EB dynamics , blood pressure , arterial stiffness , glycemia and lipemia . Methods A r and omized , controlled , double-blind , crossover dietary intervention study was performed with fifty healthy normal to overweight men and women ( age 32.0 ± 9.8 year , BMI 23.5 ± 3.0 kg/m2 ) who were r and omly assigned to consume either regular sugar or sugar-reduced foods and beverages for 8 weeks , separated by 4-week washout period . Body weight , energy intake ( EI ) , energy expenditure and vascular markers were assessed at baseline and after both interventions . Results We found that carbohydrate ( P < 0.001 ) , total sugars ( P < 0.001 ) and non-milk extrinsic sugars ( P < 0.001 ) ( % EI ) were lower , whereas fat ( P = 0.001 ) and protein ( P = 0.038 ) intakes ( % EI ) were higher on the sugar-reduced than the regular diet . No effects on body weight , blood pressure , arterial stiffness , fasting glycemia or lipemia were observed . Conclusions Consumption of sugar-reduced products , as part of a blinded dietary exchange for an 8-week period , result ed in a significant reduction in sugar intake . Body weight did not change significantly , which we propose was due to energy compensation
