  • A nutrition survey of 128 perschool children, 4 to 6 years old, in the Saemaul Youlgok day care center, located in one uplane, overpolulated, poor area of the city of Seoul, sponsered by the Korean Red Cross Society, was undertaken between August 21 and 31, 1984, to investigate dietary and nutritional status. RESULTS: Mean values of height, weight, arm circumference, girth of chest, and head circumference ranged from 95 to 100% of KIST mean. However, 4.8~14.2% of the subjects were assessed as undernourished in terms of 'weight for height'. Mean hemoglobin vcalue was 12.1±0.7gm%, and mean hematocrit value was 38.5±2.2%; 4.1% of the subjects were proven to be anemic according to the criterion of hemoglobin established by the ICNND. Mean urinary urea nitrogen/creatinine ratio was 11.4±3.8. Regarding mean energy and nutrient intake, the following percentages had intakes below two-thirds of the 1985 RDAs: 28.8% of children, for protein; 48.8% of children, for iron; and 28.8% of children, for calcium. About 25% of children had vitamin A intake below one-third of the recommended allowance. Carbohydrate provided 71% of total energy intake; protein accounted for 13%; fat provided 16%. Energy intake was divided among breakfast, lunch, dinner and snacks in a percentage ration of 19:26:21:34. The lunch, and snacks which were served at the day care center provided 36.5~79.1% of daily energy and nutrient intake. The survey clarified that the day care feding largely supplemented the inadequate dietary intakes of these young children at home. According to factor analysis of energy and nutrient intake, there were two factor groups : the first factor group, for energy, protein, carbohydrate, iron and niacin, mainly provided by grains; and the second factor group, for calcium, vitamin A, thamin, riboflavin and ascorbic acid, provided by vegetables, fruits, milk and milk products. The survey also revealed significant correlation coefficients between family factors such as family income, educational level of parents, and number of children; and dietary or nutritional status of the subjects.

  • We conducted this study to examine the effects of safflower seed granular tea containing physiologically active polyphenols on antioxidative activities and bone metabolism. Forty postmenopausal women ages 49 to 64-years were recruited from Daegu and Gyeongbuk and were randomly assigned to either a safflower tea supplement (Saf-tea) group (n=27) or a placebo group (n=13). The Saf-tea group received 20 g of safflower seed granule tea per day containing a 13% ethanol extract of defatted safflower seeds, whereas the placebo group received a similar type of tea that lacked the ethanol extract. No significant changes in nutrient intake for either the placebo or Saf-tea groups were observed before or after the study period, except vitamin A intake increased after 6 months in the Saf-tea group. Dietary phytoestrogen intakes were similar in the Saf-tea group (60.3 mg) and placebo group (52.5 mg). Significant increases in plasma genistein and enterolactone were observed in the Saf-tea group. After 6 months of supplementation, serum levels of antioxidant vitamins such as a-tocopherol and ascorbic acid increased significantly, and TBARS levels decreased in the Saf-tea group compared to the placebo group. Serum osteocalcin levels were reduced (P<0.05) in the Saf-tea group after 6 months, whereas serum osteocalcin did not change in the placebo group. Urinary deoxypyridinoline/creatinine excretion was not different between the two groups at baseline, and did not change in either group after 6 months. Bone mineral density decreased significantly in the placebo group (P<0.01) but not in the supplemented group. It was concluded that polyphenols (72 mg/day), including serotonin derivatives, in the Saf-tea had both antioxidant and potential bone protecting effects in postmenopausal women without liver toxicity.

  • 한국산 야생식용식물의 형당강화 효과를 보기위해서 일차적으로 5가지 식물(냉이, 닭의장풀, 메꽃, 며느리배꼽 및 참마)을 채집하였다. Strcpotozotocin(45mg/kg)을 미정맥으로 주사하여 당뇨병을 유발시킨 130~180g Sprague-Dawley계 흰쥐를 대조군과 실험군으로 나누어 이를 5가지 식물을 adlibitum으로 공급하였다. 식용식물섭취에 따른 각군의 체중변화는 제 3주까지는 점차 증가하다가 냉이군과 메꽃군을 제외하고는 제4주째에 증가추세가 둔화되었다. 식이이용효율은 닭의장풀군이 대조군에 비해 유의적으로 높게 나타났으며(p<0.05) 냉이군, 메꽃군, 참마군과 며느리배꼽군에서는 식이이용효율에 차이가 없었다. 닭의장풀군, 참마군과 며느리배꼽군은 대조군에 비해 혈당 감소 경향이 지속적으로 나타났고, 뇨당의 경우에서도 닭의장풀군과 참마군에서는 검출되지 않았으며 며느리배꼽군에서도 한마리를 제외하고는 뇨당이 검출되지 않아 당뇨유발쥐에서 혈당강하에 효과가 있는것으로 추정된다. 혈장 중의 cholesterol수준은 대조군에 비해 며느리배꼽군에서 약간 높은 경향을 보였으나 유의적인 차이는 없었다. 야생식용물의 건조시료 중 조섬유의 함량은 며느리배꼽이 24.4%로 가장 높았고, 가장 낮은 것은 참마로 2.5%였다. 생시료중 Vitamin C의 함량은 냉이가 193.73mg으로 가장 높았고 닭의장풀, 며느리배꼽, 메꽃슨이었고 참마가 24.6mg으로 가장 낮았다. Fe의 함량도 냉이가 14.86mg으로 높았고 참마가 가장 낮았다. Cr과 Zn의 함량도 냉이에서 높았고 참마에서 낮았다. 앞으로 야생식용산채류에 대한 성인병 예방 및 치료에 대하여 영양학적 연구가 더 많이 이루어져야 할 것이다.
