This study was peformed to assess the nutritional status of female nursing home residents by dietary intake. The subjects were 60 nursing home residents aged over 60 from 3 different nursing homes in Seoul, Cheonan and Chunchon. Dietary intake was assessed by 24-hr recall and nutrient intake was calculated using CAN-Pro and database for vitamin E established by authors. To establish vitamin E database, we analyzed vitamin E concentration using HPLC in several foods consumed frequently by nursing home residents. The results of nutrient intake were as follows; 1) Average daily intakes of energy, protein, phosphorous, iron, vitamin $B_1$ and niacin were higher than RDA, but calcium, vitamin $B_2$ and niacin of Chunchon were lower than RDA. 2) Intakes of protein, sodium and niacin of Cheonan residents were significantly higher than those of Seoul. 3) Intakes of phosphorous, potassium, vitamin $B_1$ and dietary fiber of Cheonan residents were significantly higher than Seoul and Chunchon. 4) Intakes of sodium and cholesterol of Seoul residents were higher than Cheonan and Chunchon. 5) Average daily intake of vitamin E was lower than RDA. Especially vitamin A intake of Cheonan residents was significantly lower than other two cities.

The purpose of the study was to find out the rich sources of vitamin B-complexes in Korea. Thirty kinds of vitamin B-complex (thiamin, riboflavin, and niacin) rich foods were selected based on vitamin content in 100g edible portion, single serving size, 100kcal energy content, and 1999 national annual food supply data. The results were summarized as follows: \circled1 Most of the thiamin rich foods selected were fishes: half of the foods selected was fishes when based on the contents in single serving size. On the other hand, about half of the foods selected were vegetables when based on the thiamin contents in 100kcal energy content. A relatively large number of food groups were included such as fishes, vegetables, beans, grains, meats, etc. when based on the contents in 100g edible portion, and national food supply data. \circled2 Most of the riboflavin rich foods selected were fishes and shellfishes, and vegetables: half of the foods selected were fishes and shellfishes when based on the content in 100g edible portion; two-thirds of the foods selected were vegetables when based on the content in single serving size; half of the foods selected were vegetables when based on the content in 100kcal. \circled3 The most important niacin sources are fishes: Most than 60% of the foods selected were fishes when based o the 100g edible portion, single serving size, and 100kcal energy content. Laver is very important source of all 3 vitamin B-complexes in Korea when based on the content in 100g edible portion, 100kcal energy content, and national annual food supply but not in single serving size. On the other hand, rice is rice is sources of all 3 vitamin B-complexes when based on the national annual food supply, but not in single serving size. On the other hand, rice sources of all 3 vitamin B-complexes when based on the national annual food supply, but is not included in 30 rich foods selected based on the content in 100g edible portion, single serving size, and 100kcal energy content. Mushrooms are also very important food sources of thiamin, riboflavin, and niacin when based on the vitamin content in 100g edible portion, single serving size, and 100kcal energy content but not included in 10 rich food selected based on the national food supply data.

In this study, the contents of soluble vitamins B₁ (thiamin), B₂ (riboflavin), and B₃ (niacin) in 13 kinds of rice, 11 kinds of noodles, and 15 kinds of sauces were identified. The limit of detection (LOD) and limit of quantification (LOQ) were checked to determine the reliability of the experimental results, and the accuracy of the results through the standard reference material (SRM 1849a) was verified to show excellent indicators. As for thiamin, japchaebab (stir-fried glass noodles with rice) was found to contain the highest content among rice dishes, makguksu (buckwheat noodles) among noodle dishes, and tomato spaghetti sauce among sauces. Riboflavin was identified as having the highest content in slightly spicy jajangbab (black-bean sauce with rice), bibimguksu (spicy noodles) for noodles, and spicy curry with turmeric for sauces. Niacin was highest in content in the deep and rich flavors of spicy chicken-fried rice, janchiguksu (banquet noodles), and black-bean sauce, respectively. As a result of checking the amount of recommended daily intake of water-soluble vitamins for Korean adult men and women, the highest content of riboflavin was 217.40% for men and 271.75% for women. Through this study, we are going to establish a database of nutrients for the water-soluble vitamins contained in rice, noodles, and sauces to provide the necessary dietary data concerning the content of the water-soluble vitamins contained in foods for daily recommended intake.

The chemical components of barley (Jinmichapssal, Seodunchal, and Dusan No.8) and wheat (Alchanmil, Tapdongmil, and Olgeurumil) varieties were determined in terms of proximate compositions, minerals, fatty acids, amino acids and vitamin. There are significant differences in protein and lipid (p<0.00l, respectively), fiber (p<0.05) of barleys. There are significant differences in lipid contents (p<0.00l) of wheats. The major minerals of barley were Ca 24∼31 mg%, P 117∼129 mg%, Fe 1.7∼2.9 mg%, Na 13∼18 mg%, K 227∼73 mg%, Zn 1.1∼1.2 mg%, and Mg 38∼45 mg%. The content of Ca in Jinmichapssal was significantly higher than those in the other varieties (p<0.00l). The mineral contents of wheat were Ca 39∼67 mg%, P 172∼270 mg%, Fe 3.7∼5.6 mg%, Na 15∼17 mg%, K 537∼558 mg%, Zn 2.1∼2.3 mg% and Mg 106∼127 mg%. There are significant differences in Ca, P, Fe and Mg of 3 kinds of wheat. The barleys contain vitamin B$_1$ 0.27∼0.36 mg%, vitamin B$_2$ 0.07∼0.11 mg% and niacin 1.21∼1.44 mg%. The content of vitamin B$_1$ in Jinmichapssal and Seodunchal was significantly higher than that in Dusan No.8 (p<0.0l). The content of vitamin B$_2$ in Seodunchal (0.11 mg%) was significantly higher than those in the other varieties (p<0.0l). The content of niacin in barleys was no significant differences. The wheats contain vitamin B$_1$ 0.41∼0.52 mg%, vitamin B$_2$ 0.29∼0.39 mg% and niacin 1.86∼2.81 mg%. The contents of vitamin B$_2$ in Olgeurumil (0.39 mg%) and niacin in Tapdongmil (2.81 mg%) were considerably higher than those in the other varieties. The contents of vitamin B$_1$, B$_2$, niacin in wheats were higher than those of barleys. Major fatty acids in barley and wheat varieties were linoleic acid, palmitic acid and oleic acid, which comprised of about 90%∼92% of total fatty acid. The contents of lysine, valine, and tryptophan in Dusan No.8 were significantly higher than those in the other varieties. The contents of lysine, isoleucine in Tapdongmil were significantly lower than those in the other varieties. The content of amino acid in wheat was higher than those of barleys.

We have studied the major food sources of minerals and vitamin based on the data from the National Nutrition Survey in 1993. The most important food sources was anchovy for calcium, spinach for vitamin A, and kimchi for vitamin C. The primary source of iron, thiamin, riboflavin and niacin was rice. Number of foods providing 90% of individual nutrient intake were 54 items for calcium, 40 items for iron, 20 items for vitamin A, 25 items for thiamin, 29 items for riboflavin, 39 items for niacin and 18 items for vitamin C. Among regions, amount of nutrients from same foods(10 more important food source) didn't show any significant differences (p>0.05) in minerals and vitamins studied. Over all rice was found to be the most important sources of minerals and vitamins.

The anthropometric measurements, nutrient intake, concentrations of minerals in scalp hair and urine and urinary 5-hydroxyindoleacetic acid(5-HIAA) of 30 autistic children not taking psychoactive drugs and 30 nonautistic control children were determined. The autistic children were taking significantly lower amounts of vitamin A, niacin, ascorbic acid and iron. The intake of vitamin A, niacin, and iron in autistic children were found to be 22$\%$, 75$\%$ and 58 of RDA, respectively. The decreased anthropometric measurements in height and weight of autistic children seems partly due to lower intake of these micronutrients. The food intake in vitamin and mineral group of autistic children was significantly lower. It is probably related to decreased intake of fruit in autistic children. There was no toxicity of cadmium and aluminum in both groups according to their contents in scalp hair. Autistic children showed elevated levels of hair calcium and zinc but lowered levels of copper and iron. The urinary excretion urinary excretion of 5-HIAA.

To elucidate the relationship among body mass index, nutrient intake and blood antioxidant capacity in the postmenopausal period, 60 women residing in Iksan area were recruited. Body mass index (BMI) was calculated base on height and weight, and food and nutrient intakes were estimated by 24-hour recalls of 3 non-consecutive days. Parameters of antioxidant capacity including the activities of superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) and total antioxidant capacity (TA) were measured in fasting blood samples from the subjects. The average age, height, weight and BMI of the subjects were 65 years, 151.1cm, 59.5 kg and 26.0 m/kg$^2$, respectively. The macronutrient intake rate of carbohydrate : protein : fat were 65:17.5:17.5; the mean intakes of energy and protein were 1532.7 kcal (86.3% of RDA) and 67.1 g (122.0% of RDA) respectively. The mean intakes of phosphorus, vitamin A, niacin and vitamin C were higher than Recommended Daily Allowance (RDA) for Koreans. On the other hand, calcium and riboflavin intakes were only 84.6% and 70.4% of RDA. Among the parameters of antioxidant capacity, SOD activity was significantly lower in lean subjects (BMI<20) than in the normal or overweight subjects (BMI${\geq}$20) (p<0.05). TAs of the subjects with the highest intakes of vegetables and fruits were significantly higher than those of subjects with lower intakes (p<0.05). Antioxidant capacity was compared among subjects according to 3 different nutrient intake levels according percentage of RDA for Koreans for selected nutrients with the following results: The high protein and niacin groups exhibited significantly lower TA status than those of the other intake groups (p<0.05). In conclusion, the low BMI was associated with lower SOD activity in postmenopausal women. Higher consumption of fruits and vegetables was associated with higher TA. When protein and niacin intakes were excessive, SOD activity and TA tended to be low. SOD and TA, among antioxidant indexes, seemed to be mostly influenced by other factors. Therefore, more studies on the effects of nutritional intake and the activity of antioxidant enzyme should be conducted.
