1.A Study on the Fat and Fatty Acid Intake of College Women Evaluated through Internet Nutritional Assessment System.
The Korean Journal of Nutrition 2007;40(1):78-88
The purpose of this study was to investigate dietary fat and individual fatty acids intake pattern of 174 college women living in Seoul and Gyong-gi province through internet nutritional assessment system. Each of the subjects was required to input their own food intake for three days, which included two days during the week and one day of the weekend, on the web program directly and all of the data collected were used for statistical analysis. The mean daily caloric intake of the subjects was 1,500.9 kcal which was at 71.5% of Estimated Energy Requirement (EER ). Dietary fat contributed 27.6% of the total caloric intake which was slightly higher than the recommended limit of 25%. Daily cholesterol intake was 310.0 mg, which was also high to some degree. Mean daily N6 and N3 fatty acid intake was 6.1 g and 0.9 g, respectively, and calory % calculated from each were 3.63% and 0.53%. This result showed the intake of N3 fatty acid fell in Acceptable Macronutrient Distribution Ranges (AMDR )0.5 ~1.0% but that of N6 fatty acid was somewhat lower than the AMDR 4 ~8%. N6/N3 ratio 8.5/1, however, was within the desirable range 4 ~10/1. Considering overall dietary fatty acids intake, oleic acid was the most abundant, followed by linoleic and palmitic acid. And among polyunsaturated fatty acids intake, linoleic acid was exclusively high, accounting for 97.4% of total N6 fatty acid intake. On the contrary, three fatty acids, linolenic (67.3%), DHA (21.1%)and EPA (10.0%), together supplied 98.4% of total N3 fatty acid intake. Mean P/M/S was 0.9/1.1/1.0. The subjects' intake of fat, many fatty acids and cholesterol came from diverse food groups including meats, fats and oils, milk and milk products, eggs, fish, and soybean products. Nevertheless, the subjects tended to show unfavorable fat and fatty acids intake pattern in terms of quantity and quality. Based on these results, it is important to monitor dietary fat intake pattern of the general population continuously and an internet program such as the one used for this study would be valuable, especially for assessing dietary patterns in the younger generation.

2.A Study on the Nutritional Status according to Body Mass Index in Korean College Women.
The Korean Journal of Nutrition 2004;37(10):899-907
This study was performed to investigate dietary habits and nutritional intake according to body mass index (BMI) of female college students. The subjects were 1361 students with a mean age of 20.4 years residing in Seoul and Kyonggui area. BMI (kg/m2) between > or = 18.5 to < or = 23 was considered as normal, < 18.5 as underweight and > 23 as overweight. The subjects had a mean BMI of 20.0 kg/m2 and 25% of them were classified as underweight group, 67% as normal group and 8% as overweight group. Dietary intake was assessed by food frequency method and consumption of foods and nutrients was analyzed. Frequency of meal skipping was higher in the overweight group, 16.1% of the overweight group skipped dinner. Also, the frequency of snack intake was lowest in the overweight group. The overweight group consumed less meat and fish than the normal and underweight groups. The total number of foods consumed in a day was also significantly lower than that of the underweight and normal group. The overweight group consumed less energy, protein, fat, phosphorus and niacin than the underweight and normal groups. The overweight group took iron and sodium intake lower than the normal group. Mean intakes of nutrients except clacium and iron in all three groups were over Korea RDA. The NAR (nutrient adequacy ratio) value of all nutrients, except calcium, was lower in the overweight group when compared to the normal and underweight groups, and the MAR (mean adequacy ratio) of the overweight group was 0.89, which was lower than 0.92 of the underweight and 0.93 of the normal group. The above results indicated that the deficiency of major nutrients such as calcium and iron could be inducde by less kinds of consumed foods and frequent meal skipping including dinner in the overweighted group. Therefore, balanced nutrient intake is required to maintain skeletal health and prevent anemia in overweighted female college students aged twenties.

This research was conducted to study the effect of milk consumption on blood lipid levels of Korean college women. According to milk intake from food frequency questionnaire (FFQ), top 20% of subjects were classified as high group(HG) and bottom 20% as low group (LG). Body weight, height and blood pressure were measured and BMI was calculated from the anthropometric data, but there was no significant difference between the groups. Blood samples were collected and analyzed for total cholesterol (TC), triglycerides (TG) and lipoprotein fractions. There was no significant difference in the blood level of albumin, total protein and hemoglobin between two groups, and all blood parameters were in the normal range. Blood lipid levels of two groups were not significantly different, but HDLcholesterol level were higher in HG (p < 0.05). Therefore, according to the result of the research, it is considered that drinking a pack of milk (200 ml) everyday, the average intake of dairy products of HG, is advisable to promote good health without increasing of cardiovascular disease (CVD) risk.

To study the level of change in food and nutrient intake among different age groups, a dietary survey using the 24-hour recall method was conducted among 80 female elementary school children, 84 high school students, 100 adults from 25 to 35 years old and 120 elderly people over 60 years of age. The results of the study showed that plant food and total food intake were higher in adults and animal food intake was significantly higher in children. The percentage of plant food to total food intake was highest in the elderly and that of animal food to total food intake was highest in the children. The elderly consumed significantly less meat and poultry and more fish than the other groups. However, the children consumed significantly higher amounts of milk and dairy products. The elderly had the lowest Ca intake. Carbohydrate energy intake in the elderly was 70.3%, significantly higher than that for the other age groups. All of the age groups consumed a quantity of Ca below the Korean RDA and 77.5% of the elderly consumed an amount below 75% of the RDA. Nutrient adequacy ratio (NAR) of most nutrients was lowest in the elderly. Mean adequacy ratio (MAR), an index of overall dietary quality, was 0.88 for the children, 0.84 for the adolescents, 0.80 for the adults, and 0.70 for the elderly. Therefore, the results show that food and nutrient intake changes with advancing age, and the overall quality of the diet of elderly people is lower than that for the other age groups.

The objective of this study is to develop a nutrition policy on food and nutrition labeling and education systems for fast food and carbonated soft drinks in Korea by identifying the fast food and soft drink use and by examining nutrition policies and labeling in Korea and other countries. Fast food is defined as food dispensed quickly at a restaurant generally offering a limited menu of inexpensive items, which may be mostly not nutritious. It is a growing component of the Korean diet, especially on children and adolescent population. Low nutrient dense beverages such as carbonated drinks are also increasing in the children and adolescent's diet in Korea and concern has been raised that these beverages may replace more nutritious beverage and provide empty calories. According to 2001 Korean national health and nutrition survey, fast food and carbonated soft drinks were most popular among 13 - 19 years old adolescents. Thirty six and 72 percent of adolescents consumed hamburger and carbonated beverage equal to or more than once a week, respectively. In United States, all processed food including soft drinks should disclose full nutrition information by nutrition labeling requirement. Restaurant foods are not required to provide nutrition information currently, but legislation on mandatory nutrition labeling of fast foods with other restaurant foods has been proposed currently in US. The sales of foods of minimal nutritional value, such as soft drinks, in the nation's schools is regulated by the United States Department of Agriculture. Nutrition information about fast food in US has been provided by fast food companies, non-profit organizations, hospitals and government through internet, booklet and brochure, etc, but the information is available from only a few resources in Korea. This study suggests a nutrition policy on fast food and soft drink use which includes establishing mandatory nutrition labeling and developing nutrition education materials and programs by web-site, booklet and government and school programs in Korea.

The Korean Journal of Nutrition 2006;39(5):460-466
To investigate the effects of dietary patterns on bone mineral density and its biochemical markers among Korean healthy college women for 2 years, 34 female college students were recruited through convenience sampling. Bone mineral density was measured using Dual Energy X-ray Absorptiometry (DEXA) twice at baseline and two years later. Osteocalcin and parathyroid hormone were measured in fasting serum and N-teleopeptides of type collagen (NTx) in urine. Dietary intake was assessed by 24-hour recall method 8 times with average 4-month interval. Dietary patterns with percent energy of each food group using cluster analysis were classified into two groups. The first cluster (n = 16) was characterized with high consumption of bread, snack, fast foods, beverage and considerable of rice so it was determined as "Modified dietary pattern group". The second cluster was characterized with high consumption of rice and kimchi so determined as "Traditional dietary pattern group". There were no significant difference of age, menarcheal age, body mass index but percent of body fat by pattern groups. The traditional group showed higher value of bone mineral density among lumber spine and all femur sites at baseline and 2 years later but it was not significant after adjusted for percent of body fat. Serum osteocalcin and urine NTx was higher among the traditional group at baseline than the modified group. There were similar proportions of carbohydrate:fat:protein between groups but significantly higher intake of protein, iron, vitamin A among the traditional group. In conclusion, there were two distinctive dietary patterns among Korean college women. There was difference of bone mineral density and its biochemical markers between two patterns. Further research would be necessary to explore the relationship between dietary patterns and health risks for larger-sized and various populations.

The Korean Journal of Nutrition 2006;39(5):451-459
The purpose of our study was to evaluate an association between milk consumption and bone mineral density (BMD) of female college students in Korea. The dietary data of 1,410 Korean college students living in the vicinity of Seoul area were collected through the Food Frequency Questionnaire. The mean age, height, weight and BMI of the subjects were 20.4 years, 162.1 cm, 52.7 kg, and 20.0 kg/m2 respectively. The mean intakes of energy, protein, and phosphorus were 2,398.7 kcal, 95.2 g, and 1,302.9 mg respectively, which were above their EER or Recommended Intake (RI), but the mean intake of calcium was 657.8 mg which was below its RI, and 44.0% of the subjects did not meet Estimated Average Requirement (EAR) of calcium. The daily milk consumption was 131.1 g, and the total consumption of milk and dairy product was 228.7 g. Forty five percent of the subjects consumed 50 ~200 g of milk or dairy products. After the analysis of their dietary intakes, the subjects were divided into quintiles of total consumption of milk and dairy product, which were considered as major source of dietary calcium. Ninety two subjects from the upper quintile (UQ) and 85 subjects from the lower quintile (LQ) were selected and their bone mineral densities (BMD) of lumbar spine (L1-L4) and the femur were examined by the dual energy X-ray absorptiometry. The BMD (g/cm2) of L1, L2, L3, and average of femur were 1.065, 1.150, 1.187, and 0.988 for the UQ subjects, which were significantly higher than those of the LQ subjects, 1.010, 1.090, 1.146, and 0.942 respectively. Moreover, the T-scores of the UQ were significantly higher than those of the LQ. The prevalence rates of osteopenia classified according to WHO's criterion were 12.0% in the UQ, and 20.0% in the LQ group which showed non significant. Blood levels of calcium, and phosphorus of UQ and LQ group were both within the normal range, and were not significantly different. Our results showed that UQ group presented the better status of bone mineral density and bone health. Therfore our results suggest that continuous consumption of more than one and a half cups of milk per day, which corresponds to the least amount of UQ group's consumption, would affect positively on the bone health of Korean adults.

The Korean Journal of Nutrition 2004;37(2):143-152
A dietary survey was conducted using 24-hour recall method in 80 male elementary school children, 83 high school students, 87 adults and 98 elderly people over 65 years of age to discuss food and nutrient intakes among different age groups. In observing food intake by age groups, the percentage of plant foods to total food intake was significantly higher in the elderly than other groups and that of animal foods was the highest in the children. The children consumed significantly higher amounts of milk and dairy products. Carbohydrate energy percent in the elderly people was 68.0%, significantly higher than other age groups. All age groups consumed Ca below Korean RDA and especially, 65.1% of the adolescents and 68.4% of the elderly consumed below 75% of RDA. Nutrient adequacy ratio (NAR) of most nutrients was lowest in the elderly. Mean adequacy ratio (MAR), an index of overall dietary quality, was 0.94 for the children, 0.84 for the adolescents, 0.84 for the adults, and 0.73 for the elderly. The above results suggest that food and nutrient intakes have been differently affected with advancing age, and overall dietary quality of the elderly people is lower than that of other age groups.
