Objectives: The adverse health effects of consuming sugar-sweetened beverages have been studied worldwide. However, no recent report on the actual sugar contents of Japanese sugar-sweetened beverages is available. Therefore, we analyzed the glucose, fructose, and sucrose contents of common Japanese beverages.
Methods: The glucose, fructose, and sucrose contents of 49 beverages (8 energy drinks, 11 sodas, 4 fruit juices, 7 probiotic drinks, 4 sports drinks, 5 coffee drinks, 6 green tea drinks, and 4 black tea drinks) were determined using enzymatic methods.
Results: Three zero calorie drinks, 2 sugarless coffee drinks, and 6 green tea drinks contained no sugar. Three coffee drinks contained only sucrose. The orders of median glucose, fructose, and sucrose contents in the categories of beverages containing sugars were as follows: for glucose, fruit juice > energy drink ≥ soda ≫ probiotic drink > black tea drink > sports drink; for fructose, probiotic drink ≥ energy drink > fruit juice > soda ≫ sports drink > black tea drink; and for sucrose, black tea drink > energy drink ≥ probiotic drink > fruit juice > soda > coffee drink ≫ sports drink. The total fructose as a percentage of the total sugar content in the 38 sugar-containing beverages was between 40% and 60%. The total sugar content analyzed was not always equivalent to the carbohydrate content indicated on the nutrition label.
Conclusions: These results indicate that information on the actual sugar content of common Japanese beverages is necessary for the exact assessment of beverage-derived sugar intake.
