홍희옥(Hong Heeok),이정숙(Lee Jung Sug) 韓國營養學會 2010 Journal of Nutrition and Health Vol.43 No.5
The relationship between food and nutrient intake, glycemic index (GI), glycemic load (GL), and body weight was investigated with high school girls residing in Seoul. As subjects, 159 girls were divided into a normal weight (NW) group (18.5 ㎏/㎠ ≤ BMI < 23 ㎏/㎠, n = 110) and an overweight (OW) group (BMI ≥ 23 ㎏/㎠, n = 49) by body mass index (BMI). The food and nutrient intake data obtained by the 3-day food record were analyzed by Can pro 3.0 software. Anthropometric measurements were collected from each subject. Daily dietary GI (DGI) and dietary GL (DGL) were calculated from the 3-day food record. Body weights and BMI of NW were 52.4 ㎏ and 20.4 ㎏/㎠ and those of OW were 65.2 ㎏ and 25.4 ㎏/㎠, respectively. Total food, animal food, and other food intakes of NW were higher than those of OW, and vegetable food intakes of NW were lower than those of OW. Sugars intake of NW was significantly higher than OW. Nutrient intakes were not different between the two groups. Dietary fiber, calcium, and folate intakes of NW and OW were under 65% of the dietary reference intakes (DRIs). Major food sources of energy intake for both groups were rice, pizza, ice cream, pork, instant noodle, and chicken. Mean adequacy ratio (MAR), an index of overall dietary quality, was higher in NW (0.82) than in OW (0.80). Mean daily DGI of NW and OW was 66.5 and 66.4, respectively. Mean daily DGL of NW and OW was higher in NW (162.0) than in OW (155.9). DGI and DGL adjusted to energy intake were not significantly correlated with anthropometric data.

This study investigated the therapeutic effects of Inonotus obliqua extract on blood glucose, insulin, and other biochemical parameters in genetically diabetic mice (C57BL/KsJ?m<SUP>+/+</SUP> Lepr<SUP>db</SUP>): The mice were divided into four groups - control, Chaga 1 (dose of 0.09 ㎎/㎏ of body weight) , Chaga 5 (5 times of Chaga 1), and Chaga 10 (10 times of Chaga 1) - according to supplemented dose. Inonotus obliqua extract was orally administered to the animals for 6 weeks. The body and organ (liver and kidney) weights were not different among groups. Fasting blood glucose level was significantly lower in the Chaga S group compared with the control (p < 0.05). Hemoglobin Alc content was significantly lower in the Chaga 5 group compared with either the control and Chaga 1 group (p < 0.05). There was no significant difference in serum insulin level among groups. The glucose-6-phosphatase activity in liver was significantly the lowest in Chaga 10 group and was significantly lower in Chaga 5 group as compared with those of control and Chaga 1 groups. Therefore, the results of this study demonstrate that Inonotus obliqua extract alleviates many of the symptoms of diabetes in genetically obese mice and may offer a possibility as a therapeutic supplement for the normalization of blood glucose levels in human with hyperglycemia and have beneficial effects in patients with noninsulin-dependent diabetes mellitus.

This study was conducted to examine food and nutrient intakes of weekday and weekend with 329 high school boys residing in Seoul using the 3-day food record. Frequency for breakfast skipping was the highest as compared with lunch and dinner skipping. Frequencies for breakfast and lunch skipping were significantly higher in weekend than weekday (p < 0.05). The daily average food, vegetable food and animal food intakes were 1,327.6 g, 800.5 g, and 425.8 g, respectively. Total food and vegetable food intakes of weekday were significantly higher than weekend (p < 0.05). The dietary variety score (DVS) was 20.5 in daily average, 23.3 in weekday and 15.1 in weekend, which showed significantly higher in weekday than weekend (p < 0.05). The daily averages of energy, protein, fat and carbohydrate intake were 2244.9 kcal, 89 g, 72.6 g, and 311.2 g, respectively. Fat intake was significantly lower and carbohydrate, fiber, phosphate, iron, sodium, potassium, vitamin A, niacin, folate, and vitamin C intakes were significantly higher in weekday than weekend (p < 0.05). The percentages of energy intake from carbohydrate, protein, and fat were 55.4%, 15.8%, 28.8% in daily average, 56.8%, 15.8%, 27.4% in weekday and 53.6%, 15.8%, 30.7% in weekend, respectively. The percentages of energy intake from carbohydrate in weekday and weekend were below 60%, and that from fat was above 27% in weekday and weekend. Carbohydrate intake was significantly higher and fat intake was significantly lower in weekday than weekend (p < 0.05). Energy intakes of daily average, weekday and weekend were above 83% as compared with estimated energy requirement (EER). Intakes of dietary fiber, calcium, potassium, vitamin C, riboflavin and folate were below 75% as compared with adequate intake (AI) or recommended intake (RI). Mean adequacy ratios (MAR), an index of overall dietary quality were 0.78 in daily average, 0.80 in weekday and 0.75 in weekend. MAR of weekend showed significantly lower than weekday (p < 0.05). This study revealed that the overall nutrient intake status was worse in weekend than weekday among high school boys. (Korean J Nutr 2008; 41(6): 539 ~ 549)

This study was conducted to study the relationship between food intakes, glycemic index (GI), glycemic load (GL), and body weight with high school boys residing in Seoul. The subjects of 329 boys were divided into normal weight group (BMI < 23 ㎏/㎡, n = 212) and overweight group (BMI ≥ 23 ㎏/㎡, n = 117) by body mass index (BMI). The food intakes data obtained by the 3-day food record were analyzed by Can pro 3.0 software. Anthropometric measurements and physical activities were collected from each subject. Daily dietary glycemic index (DGI) and dietary glycemic load (DGL) were calculated from the 3-day food record. Body weights and BMI of normal weight group were 58.8 ㎏ and 19.9 ㎏/㎡ and those of overweight group were 79.2 ㎏ and 26.8 ㎏/㎡, which were significantly different between two groups (p < 0.05). Total food and animal food intakes of normal weight group were significantly higher than overweight group (p < 0.05), and vegetable food and other food intakes of normal weight group showed higher than overweight group. All nutrient intakes of normal weight group were higher than overweight group. Dietary fiber, calcium, potassium and folate intakes of normal weight group and overweight group were under 65% of the dietary reference intakes (DRIs). Major food sources of energy intake for both groups were rice, pork and instant noodle in order. Mean adequacy ratio (MAR), an index of overall dietary quality were 0.83 in normal weight group and 0.79 in overweight group, which showed significantly higher in normal weight group than overweight group (p < 0.05). Mean daily dietary GI of normal weight group and overweight group were 67.7 and 68.2, respectively. Mean daily dietary GL of normal weight group and overweight group were 214.6 and 202.7, respectively, and which was significantly different between the two groups (p < 0.05). Major food sources contributed to DGI and DGL were rice (≥ 55%) in both groups. DGI and DGL were not significantly correlated with anthropometric data. Activity adjusted to energy intake was negatively correlated with percentage of body fat (r =-0.1308, p < 0.01) and that was positively correlated with height (r = 0.1227, p < 0.05) and lean body mass (r = 0.1351, p < 0.05).

This study was conducted to examine nutrient intake status and iron food sources by dietary iron density of high school girls in Seoul. The subjects of 226 girls were divided into High group (≥ 6 ㎎/1,000 ㎉, N = 115) and Low group (< 6 ㎎/1,000 ㎉, N = 111) by dietary iron density. The nutrient intake data obtained by 24-hour recall method were analyzed by Can pro 3,0 software. Mean age of all subjects was 16.4 years old, heights and weights of High group and Low group were 164.5 ㎝, 53.4 ㎏ and 161.7 ㎝, 51.7 ㎏, respectively. The body mass index (BMI) of High group and Low group was 20.5 ㎏/㎡ and 19.8 ㎏/㎡, respectively. Most nutrient intakes except energy and lipid intakes of High group were higher than those of Low group. High group showed significantly higher intakes of total iron, vegetable iron and animal iron than Low group. Ca and folate intakes of High group were under 75% of the recommended intake (RI) and Ca, iron, folate and vitamin C intakes of Low group were under 65% of RI. The percentage of subjects who consumed iron less than estimated average requirements (EAR) were 40.0% in High group and 77.5% in Low group. Total food intakes of High group showed higher than that of Low group. Total animal food intakes were significantly higher and total vegetable food intakes were significantly lower in Low group than those of High group. Iron intake from meats, fishes, shell fishes and seasonings were significantly higher in High group than Low group. Iron intake from milk and dairy products were significantly lower in High group than Low group. Major food sources of iron were rice, bean curd, pork, and egg in order among both groups.
