Abstract

Tea and herb beverages are popular refreshing and healthy beverages. Sugar and high-fructose corn syrup (HFCS) are usually added as a sweetener. Previous studies showed that high dietary fructose intake can lead to obesity and metabolic syndrome, which is associated with insulin resistance, fatty liver, hyperuricemia, and cardiovascular disease. The aim of this study is to measure glucose and fructose contents in tea and herbal commercial beverages. Twenty-four beverages were collected, consisting of 15 tea beverages (green, black, and white tea) and 9 herbal beverages (Chrysanthemum, Luo Han Gao tea, and Jublieng). Nutrition facts were recorded, and glucose and fructose were analyzed by using the enzymatic method. The results showed that glucose and fructose in tea beverages were 39.5 ± 23.6 and 23.7 ± 15.5 mg/mL (mean ± SD), respectively, while those in herbal beverages were 38.5 ± 21.3 and 24.9 ± 12.4 mg/mL (mean ± SD), respectively. The lowest and highest glucose and fructose levels in tea beverages were 7.6 and 91.6 mg/mL, while those in herbal beverages were 11.6 and 78.3 mg/mL, respectively. In conclusion, tea and herbal beverages may contain high glucose and fructose contents, which can affect health when consumed at high amounts.
