This study was designed to investigate the effect of nutrient intake on bone mineral density (BMD) of the lumbar spine(L2longrightarrowL4) in 41 postmenopausal women. The BMD of the lumbar spine was positively correlated with caiorie protein animal protein fat animal fat calcium animal calcium milk ad dairy calcium phosphorus iron animal iron vitamin A thiamin animal calcium milk and dairy calcium phosphorus iron animal iron vitamin A thiamin riboflavin niacin and ascorbic acid intake. Postmenopausal wmen of BMD$\geq$100% showed enhanced calorie protein fat calcium phosphrous niacin intake compared women of BMD<100% In the group of calorie protein riboflavin intake$\geq$recommended dietary allowances(RDA) BMD was significantly higher than BMD in the group of these nutrient intakes$\geq$700 mg/d is significantly higher than BMD that of examined using stepwise multiple regression analysis. From this analysis in subjects aged 50~59 years fat intake only in subjects aged 60~69 years niacin intake Ca/P in total subjects fat riboflavin intake were signifiant independent predictors of BMD In the group of menopausal significant independent predictor of BMD This study suggests that dietary calcium is a major constituent affecting lumbar spin BMD in postmenopausal women whose menopausal period is over than 5 years.

The objectives of the present study were to measure the content of iron, copper and zinc in human milk and to estimate the intake of iron, copper and zinc of breast-fed infants during the early period of lactation. Twenty-five lactating women who delivered in a hospital in Seoul volunteered for the study. Milk samples were collected at day 2, 3, 4, 5, 6, 7, 15 and 30 postpartum. The contents of iron, copper and zinc were determined using the atomic absorption spectrophotometer after wet digestion. The intakes of iron, copper and zinc of infants were estimated by multiplization with the infant milk intake reported in our laboratory. The content of iron was 0.58 $\mu\textrm{g}$/g in colostrum, 0.48 $\mu\textrm{g}$/g in transitional milk and 0.39 $\mu\textrm{g}$/g in mature milk while the estimated iron intake of infants was 271, 255 and 259 $\mu\textrm{g}$/day, respectively. The content of copper in the milk was 0.45 $\mu\textrm{g}$/g in colostrum, 0.43 $\mu\textrm{g}$/g in transitional milk and 0.33 $\mu\textrm{g}$/g in mature milk while the estimated copper intake of infants was 210, 229 and 220 $\mu\textrm{g}$/day, respectively. The content of zinc in the milk was 5.24 $\mu\textrm{g}$/g in colostrum, 3.70 $\mu\textrm{g}$/g in transitional milk, 2.93 $\mu\textrm{g}$/g in mature milk while the estimated zinc intake of infants was 2452, 1968, and 1949 $\mu\textrm{g}$/day, respectively. These results suggest that copper and zinc intake of infants are met to RDA but iron is not.

The purpose of this study was to evaluate nutritional value of traditional fermented foods by dietary intake of university students living in Chungnam. 210 students were asked for their daily food intake using 24-hour recall method for 3 days. And daily nutrient intakes from total foods and fermented foods were analyzed and compared. The mean weight, height, and BMI of the subjects were 67.36㎏, 174.39㎝, 22.15㎏/$m^2$ in men and 53.45㎏, 161.86㎝, 20.40㎏/$m^2$ in women, respectively. The daily intakes of protein, phosphorus, and vitamin B1 were 106.82%, 137.88%, and 108.99% of the Korean RDA. However, the energy, calcium, iron, vitamin A, vitamin B2, niacin, vitamin C intakes did not reached the RDA for Koreans. The fermented food intake was 9.09% of total food intake. And the percentages of fermented food intakes were 81.53% for Kimchi and 14.75% for Chang. The vegetable protein, vegetable oil, dietary fiber, calcium, phosphorus, iron, sodium, potassium, vitamin A, vitamin B1, vitamin B2, niacin and vitamin C intakes per 1000㎉ consumption from fermented foods were significantly higher than those from total foods. The fermented food intake showed positive correlation with iron, and plant iron intakes. In conclusion, the percentage of fermented food intake was about 9% and the major items were Kimchi and alcoholi beverages in university students. Fermented food intake may be important to improve the intakes of calcium, iron and vitamin.

This research involved a survey on the dietary patterns of children and adolescents living in group homes, to find out their wrong eating habits and to devise measures for correcting their problems. The BMIs of the subject children and adolescents in group homes were measured, and the result showed that although many of them appeared to have normal weights, about 42.2% were actually underweight. Most of them had meals regularly, three times a day at fixed times. However, half of them frequently skipped breakfast because of the lack of time in the morning. In addition, more than half of them had the habit of having imbalanced diets, especially with low vegetable intake. The score for their satisfaction toward meals at group homes were highest (3.97) with the taste of food, while it was relatively lower (3.61) with the variety of food than with the other items. The average score for their snack intake was 3.47, showing that the majority of them had the habit of eating snacks, while the largest portion (26.0%) of them preferred bread and cookies. According to the result of the analysis on their food intake, overall calorie intake was about 82~96% of estimated energy requirements, while that of the male subjects aged 12 or older was about 82% of the standard energy requirements. Their overall intake of calcium and potassium was lower than recommended nutrition intake, but sodium intake was higher than 3 times recommended intake. Especially, in addition to calcium and potassium, the male subjects aged 15 or older showed low intake of dietary fiber, iron, zinc, riboflavin, niacin, vitamin C and folate also; whereas the female subjects aged 15 or older showed low intake of iron, zinc, riboflavin and folate also. Taken together, it was concluded that government level of dietary life-related support and management would be necessary for the healthy growth and development of children and adolescents in group homes.

Food intake patterns and iron nutritional status of male and female college students were studied based on dietary iron density. Dietary data were collected using the method of 24-hour recalls for 3 consecutive days from 106 students, and fasting blood were drawn to measure iron nutritional status indicators such as total iron binding capacity, serum iron, hematocrit, hemoglobin, and red blood cell count. Mean daily iron intakes of male and female students were 13.3㎎ and 10.0㎎, which were 107% and 63% of the RDA, respectively. However, dietary iron density were similar between male and female students as 5.9㎎/1,000㎉ and 5.7㎎/1,000㎉, respectively. The diets were divided into two groups according to iron density; high iron density group (6㎎/1,000㎉ or more) and low iron density group (less than 6㎎/1,000㎉). The students in high density group had lower intakes of energy, especially fat, than those in low density group. Female students in high density group showed significantly higher intakes of iron, and non-heme iron and folate than those of low density group. The students in high density group consumed more rice, hamburger, and eggs, while those in low density group consumed more Ra-myon and alcoholic beverages. The students in high density group consumed greater proportions of iron from plant-origin foods. Vegetables, legumes and seasonings were the food groups that female students in high density group consumed significantly more than those in low density group. Also the percentages of female students with iron deficiency were higher in low density group. These results suggest that diet with high iron density is important to improve iron nutritional status of women, and further research about the effective way to increase iron density in our diet is needed.

It is necessary to compare the dietary characteristics among different age groups because different nutritional problems require different dietary applications. This study was performed to identify the nutritional characteristics of Korean diet among different age groups. The study subjects consisted of preschool children(PC), elementary school children(EC), high school students(HS), college students(CS), and adults over 30 years old living in Seoul and the surrounding areas. The subjects over 30 years old were classified to 30-49 years, 50-69 years, and over 70 years. A dietary survey was conducted using 24-hour recall method and data were collected from 2392 subjects. Energy intake was as much as 1771kcal for PC, 2139kcal for EC, 2475kcal for HS, 2276kcal for CS, 1860kcal for 30-49 years, 1715kcal for 50-69 years, 1326kcal for over 70 years. The subjects of PC, EC, HS, and CS groups got about 25% of energy from fat, but the subjects in 30-49 years, 16%, those in 50-69 years, 15%, and those over 70 years, 13%. The energy consumption from protein was about 15% in each age group. Percent of energy intake as Korean RDA was greater than 100% for PC, EC, HS, and male CS groups. The percent intake for RDA of calcium, iron, vitamin A, and vitamin B$_2$was low in most age group. Iron intake was inadequate in female of PC and CS groups, and subjects in 30-49 years and over 70 years. Mean adequacy ratio(MAR) was 0.9 in PC, and decreased with increase of age. Therefore MAR did not reach to 0.7 among subjects over 70 years. Index of nutritional quality(INQ) for calcium, iron, vitamin A, and vitamin B was below 1 in most age groups. From these results, major nutritional problems of each age group were overall inadequate intakes of calcium and iron, excess consumption of protein and fat for PC, EC, HS, and CS groups, and inadequate nutrients intake of subjects over 70 years old. According to these results, each age group seems to need specific nutritional intervention. (Korean J Nutrition 34(5) : 554~567, 2001)

This study examined the effects of excess intake of calcium(Ca) and iron(Fe) supplements on iron bioavailability, liver and kidney functions in anemic model rats. Seven-week-old female rats were first fed and Fe-deficient diet for ten weeks, and then fed one of nine experimental diets for an additional eight weeks, containing three levels of Ca, normal (0.5%) or high(1.5%) or excess (2.5%) and three levels of Fe, normal(35ppm) or high(210 ppm) or excess(350ppm). In anemic model rats, serum Fe, total iron binding capacity(TIBC), hemogolin(Hb), hematocrit(Hct) and liver Fe contents were significantly decreased. Apparent Fe absorption significantly increased with increasing dietary Fe levels, and decreased with increasing dietary Ca levels. serum Fe concentration significantly increased in rats fed a high- and excess-Fe diet, and decreased in rats fed a excess-Ca diet. TIBC was decreawed in rats fed a excess-Ca diet, and transferrin saturation(%) increased in rats fed ahigh- and excess-Fe diet. Hb and Hct were decreased in rats fed an excess-Ca diet regardless of dietary Fe levels. Fe and thiobarbituric acid reactin gsubstance(TBARS) Contents of liver significantly increased in rats fed a high- and excess0-Fe diet, and decreased in rats fed a high- and excess-Ca diet. Fe content of the spleen showed similar results. Urinary creatinine and GFR increased in rats fed an excess-Ca diet regardless of dietary Fe levels. GOT, GPT and LDH were not significantly affected by dietary Ca and Fe levels. These results suggest that excess intake of Fe may increase liver Fe deposits and TBARS, and excess intake of Ca may decrease Fe bioavailability and kidney function leading to potential health problems in anemic model rats.
