우리나라 다빈도 섭취 과일의 당 함량 및 혈당지수에 관한 연구 = Sugar composition and glycemic indices of frequently consumed fruits in Korea

다국어 초록 (Multilingual Abstract)

Fruits are generally recommended for a balanced meal, as they are good sources of vitamins, minerals, and fiber, which may improve blood glucose control. However, fruits have simple sugars with a wide glycemic index (GI) range. The purpose of this study was to analyze the sugar content and composition and to determine the glycemic indices of the most frequently consumed fruits in Korea, including apple, tangerine, pear, water melon, persimmon, grape, oriental melon, and peach. The sugar content and composition of the fruits were analyzed by high performance anion-exchange chromatography (Dinonex model DX-600). The GI of the fruits was measured in 13 healthy subjects (seven females and six males) after permission was received from the University Hospital institutional review board (KHU-IRB 1114-06). The subjects consumed 50 g of glucose as a reference and carbohydrate portions of eight fruits. Blood samples were collected at 0, 30, 60, 90, and 120 min after consuming the fruits. The GI values for the fruits were calculated by expressing the increase in the area under the blood glucose response curve for each subject. As a result, the total sugar contents of 100 g fruits were: grape (13.9 g), apple (12.3 g), persimmon (11.9 g), oriental melon (11.2 g), watermelon (9.3 g), tangerine (8.9 g), peach (8.6 g), and pear (8.3 g). The GI values of the fruits were as follows: GI value of peach (56.5 ± 14.17), watermelon (53.5 ± 18.07), oriental melon (51.2 ± 18.14), tangerine (50.4 ± 15.16), grape (48.1 ± 14.05), persimmon (42.9 ± 18.92), pear (35.7 ± 14.38), and apple (33.5 ± 11.92). These findings will help individuals choose fruit for controlling blood sugar. (Korean J Nutr 2012; 45(2): 192 ~ 200)
