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 .
Effect of the addition of simple sugars to mixed meals on the glycemic control of insulin treated diabetic patients.
In order to evaluate the long term effects of a daily intake of simple sugars upon the glycemic control , 10 insulin treated diabetic out patients received , according to a r and omized cross over design , a conventional or a sucrose-enriched isocaloric , isoglucidic diet ( about 20 g sucrose per day , given as desserts and /or soft drinks during or after mixed meals ) for 3 months each . The daily insulin doses remained identical during both diets : 0.58 + /- 0.07 vs 0.58 + /- 0.06 U/kg body weight ( mean + /- SEM ) after conventional and sugar-enriched diet , respectively . The percentages of short acting insulin were also similar : 50 + /- 4 vs 49 + /- 4 % . The mean glycemic profiles after lunch and dinner were comparable with both regimens . Moreover , glycosylated hemoglobin levels were 10.0 + /- 0.3 vs 9.9 + /- 0.4 % after conventional and sucrose enriched diet , respectively . Plasma cholesterol and triglycerides remained unchanged . In conclusion , a relatively small daily intake of sucrose for 3 months has no clinical and /or metabolic side effects . Therefore , it seems no longer justified to completely ban sucrose from the diet of diabetic patients
