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 .
Sucrose-sweetened beverages increase fat storage in the liver, muscle, and visceral fat depot: a 6-mo randomized intervention study.
BACKGROUND The consumption of sucrose-sweetened soft drinks ( SSSDs ) has been associated with obesity , the metabolic syndrome , and cardiovascular disorders in observational and short-term intervention studies . Too few long-term intervention studies in humans have examined the effects of soft drinks . OBJECTIVE We compared the effects of SSSDs with those of isocaloric milk and a noncaloric soft drink on changes in total fat mass and ectopic fat deposition ( in liver and muscle tissue ) . DESIGN Overweight subjects ( n = 47 ) were r and omly assigned to 4 different test drinks ( 1 L/d for 6 mo ) : SSSD ( regular cola ) , isocaloric semiskim milk , aspartame-sweetened diet cola , and water . The amount of intrahepatic fat and intramyocellular fat was measured with (1)H-magnetic resonance spectroscopy . Other endpoints were fat mass , fat distribution ( dual-energy X-ray absorptiometry and magnetic resonance imaging ) , and metabolic risk factors . RESULTS The relative changes between baseline and the end of 6-mo intervention were significantly higher in the regular cola group than in the 3 other groups for liver fat ( 132 - 143 % , sex-adjusted mean ; P < 0.01 ) , skeletal muscle fat ( 117 - 221 % ; P < 0.05 ) , visceral fat ( 24 - 31 % ; P < 0.05 ) , blood triglycerides ( 32 % ; P < 0.01 ) , and total cholesterol ( 11 % ; P < 0.01 ) . Total fat mass was not significantly different between the 4 beverage groups . Milk and diet cola reduced systolic blood pressure by 10 - 15 % compared with regular cola ( P < 0.05 ) . Otherwise , diet cola had effects similar to those of water . CONCLUSION Daily intake of SSSDs for 6 mo increases ectopic fat accumulation and lipids compared with milk , diet cola , and water . Thus , daily intake of SSSDs is likely to enhance the risk of cardiovascular and metabolic diseases . This trial is registered at clinical trials.gov as NCT00777647
