The hypoglycemic effects of Korean wild vegetables : Capsella bursa-pastoris Medicus(CBM) Commelina communis L. (CCL) Calystegics japonica Choisy(CJC) Discorea japonica Thunb(DJT) and Persicaria perfolidata Gross(PPG) in diabetic rats were determined. Sixty male Sprague-Dawley diabetic rats(130~180g) induced by the streptozotocin (45mg/kg) injection into the tail vein were fed either a control or experimental diets for four weeks. The plasma levels of glucose and cholesterol were measured. The urinary glucose levels were monitored. Crude fiber mineral(Ca, Fe, Zn and Cr) and ascorbic acid contents of the wild vegetables were analyzed. The extents of blood glucose decrement in CCL. DJT or PPG fed rats were greater than that in the control group. This extents of decrement in CBM or CJC fed rats were not significan-tly different from that in the control group. The urinary glucose was shown to be negative to Band reagent strip in CCL or DJT group at the 4th week. The plasma cholesterol levels of all the groups including control group were not essentially different. It is suggested that the intakes of CCL or DJT could be useful for prevetive and therapeutic approches to alleviate the hyperglycemic status in diabetes mellitus.

The purpose of this study was to obtain baseline data on nutritional management of women's bone health. We examined the bone mineral density (BMD) by ultrasound bone densitometer, anthropometric measurement and dietary intake to assess the nutrient intakes. The subjects were 102 Korean female college students (normal=59, bone disease group [osteopenia+osteoporosis]=43) and the mean age was 21.4 yr. Mean T-score (BMD) were -0.42 and -1.52 in normal and bone disease groups, respectively. Anthropometric measurement showed that 59% of the subjects were normal weight and bone disease group had lower value than normal group in majority of anthropometric index. The average energy intake was 1539.7 kcal, which was 73% of Korean EER. The subjects had lower vitamin C, folic acid, Ca and K intake than Korean RI independent of BMD. Bone disease group (1:2.05) showed significantly lower Ca:P ratio than normal group (1:1.86). Normal group had more intake frequency of milk and milk product than bone disease group. In relation to anthropometric index with T-score, significant correlations have been found in weight, PM, BFM, MM, TBW, SLM, FFM WHR, BMI and SMM. In relation to dietary factors with T-score, significant correlations have been found relating to intake frequency of milk and milk product. Our results indicate that for nutrients, ratio and balance may be more influential than intake for bone health in young women.

Purpose: This study was performed to examine associations of intakes of milk and dairy products, pulses, and soy foods with bone health in Koreans aged 50 yr and older. Methods: A total of 3,201 men and 3,581 women aged 50 yr and older who participated in the 2008~2011 Korea National Health and Nutrition Examination Survey were grouped by sex and age groups of 50~64 yr and 65 yr and older. Subjects within each sex and age group were divided into three bone health groups: normal, osteopenia, and osteoporosis groups based on bone mineral density. Intakes of nutrients and foods derived from 24-hour recall data were compared among three bone health groups. Associations between intake frequencies of foods, including milk, yogurt, tofu, or soy milk, and osteoporosis risk were evaluated based on confounding risk factor-adjusted logistic regression. Results: Calcium intake was in the order of normal, osteopenia, and osteoporosis in men (p < 0.01) and women (p < 0.05) aged 50~64 yr as well as in men aged 65 yr and older (p < 0.001). In women aged 50~64 yr, intake of milk and dairy products was lower in the osteoporosis group (p < 0.01) as compared with the osteopenia group. Intake of pulses or tofu was not significantly different among bone health groups. Odds ratio (OR) for milk intake frequency (${\geq}2$ times/week) compared to intake frequency less than 1 time/month was 0.45 (95% CI 0.24~0.85, p for trend = 0.022) in men aged 65 yr and older. The OR for yogurt intake frequency (1 time/month~1 time/week) was 0.47 (95% CI 0.30~0.73, p for trend = 0.019) in women aged 50~64 yr. Intake frequency of tofu or soy milk was not associated with reduced risk of osteoporosis in all groups. Conclusion: Dairy food intake was significantly associated with bone health, and its effect was sex- and age group-specific, whereas soy food intake was not. Dietary intervention to prevent osteoporosis would be effective for women aged 50~64 yr old and for men aged 65 yr and older.
