Abstract
AbstractBackgroundThe adverse health effects of sugar-sweetened beverage consumption have been studied worldwide. There are several reports on actual sugar contents in sugar-sweetened beverages. However, there is no recent report on actual sugar contents in Japanese sugar-sweetened beverages. Therefore, we attempted to analyze glucose, fructose, and sucrose contents in Japanese common beverages.MethodsGlucose, fructose, and sucrose contents in 49 beverages including 8 energy drinks, 11 sodas, 4 fruit juices, 7 probiotic drinks, 4 sports drinks, 5 coffee drinks, 6 green tea drinks, and 4 tea drinks were determined using the enzymatic methods.ResultsTow 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 categorized 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 rate of total fructose content in total sugar content in 38 sugar-containing beverages was approximately 40-60%. The total sugar content analyzed was not always equivalent to carbohydrate content indicated on the nutrition label.ConclusionsThese results indicate that actual sugar content in Japanese common beverages is necessary for the exact assessment of beverage-derived sugar intake.
