BACKGROUND/OBJECTIVES: The effects of fish consumption by subjects with prediabetes on the metabolic risk factors were examined based on the data from the $6^{th}$ Korea National Health and Nutrition Examination Surveys in 2015. SUBJECTS/METHODS: A total of 1,520 subjects who agreed to participate in a blood test and dietary intake survey were divided into a prediabetes group and normal blood glucose group, and the level of the subjects' fish consumption was divided into ${\leq}17.0g/day$, 18.0-93.0 g/day, and ${\geq}94g/day$. The correlation between the level of fish intake and the metabolic risk factors was evaluated by multinomial logistic regression analysis. RESULTS: A significant difference in the gender distribution was observed in the prediabetes group, which is a group with a high risk of non-communicable diseases, according to the fish intake, and there were significant differences in the total energy intake, protein intake, n-3 fatty acids intake, and the intakes of sodium and micro-nutrients according to the intake group (P < 0.05). In addition, the blood total cholesterol (TC) decreased 0.422 fold in model 1 (unadjusted) [95% confidence interval (CI): 0.211-0.845] and 0.422 fold in model 2 (adjusted for sex) (95% CI: 0.210-0.846) in those with a fish intake of 18.0-93.0 g/day (P < 0.05) compared to those with a fish intake of ${\leq}17.0g/day$. The blood TC decreased 0.555 fold (95% CI: 0.311-0.989) in model 1 and 0.549 fold (95% CI: 0.302-0.997) in model 2 in those with a fish intake of ${\geq}94g/day$ compared to those with a fish intake of ${\leq}17.0g/day$ (P < 0.05). CONCLUSION: Subjects with prediabetes or the metabolic risk factors can maintain their blood low density lipoprotein cholesterol (LDL-C) and blood TC concentrations at the optimal level by consuming fish (18.0-93.0 g/day).

This study analyzed the intake of calories and nutrients based on the consumption of black beans. The survey was conducted on 124 college students (male: 42, female: 82), of whom 63.7% (79 students) were consumers of black beans. The calorie intake of the black bean intake group (1599.81±555.48 kcal) was significantly higher than that of the non-black bean intake group (1259.99±507.58 kcal) (P<0.01). The black bean intake group also showed a significantly higher intake of crude protein (P<0.05), plant protein (P<0.01), animal protein (P<0.05), crude fiber (P<0.001), plant calcium (P<0.001), plant iron (P<0.001), zinc (P<0.01), vitamin B2 (P<0.01), vitamin C (P<0.01), vitamin E (P<0.01) and folic acid (P<0.001) compared to the non-black bean intake group. There was a positive correlation between the frequency of black bean intake and crude fiber (P<0.05), plant calcium (P<0.05), plant iron (P<0.05), and folic acid (P<0.05). Overall, the black bean intake group was more likely to eat black sesame 13.82 times (95% CI=5.37, 35.55), white beans 10.79 times (95% CI=3.53, 33.02), mung beans 7.22 times (95% CI=2.58, 20.23), and brown rice 4.72 times (95% CI=1.88, 11.84), than the non-black bean intake group. In conclusion, we believe that black beans constitute a vital food ingredient that is necessary to provide Korean college students with a well-balanced diet.

BACKGROUND/OBJECTIVES: Diet plays an important role in growth and development of children. However, dietary intakes of children living in either rural or urban areas can be influenced by household income. This cross-sectional study examined energy, nutrient and food group intakes of 749 urban children (1-10 years old) by household income status. SUBJECTS/METHODS: Children's dietary intakes were obtained using food recall and record for two days. Diet adequacy was assessed based on recommended intakes of energy and nutrients and food group servings. RESULTS: For toddlers, all nutrients except dietary fiber (5.5 g) exceeded recommended intakes. Among older children (preschoolers and school children), calcium (548 mg, 435 mg) and dietary fiber (7.4 g, 9.4 g) did not meet recommendations while percentage of energy from total fat and saturated fats exceeded 30% and 10%, respectively. The mean sodium intakes of preschoolers (1,684 mg) and school children (2,000 mg) were relatively high. Toddlers in all income groups had similar energy and nutrient intakes and percentages meeting the recommended intakes. However, low income older children had lowest intakes of energy (P < 0.05) and most nutrients (P < 0.05) and highest proportions that did not meet recommended energy and nutrient intakes. For all food groups, except milk and dairy products, all age groups had mean intakes below the recommended servings. Compared to middle and high income groups, low income preschoolers had the lowest mean intake of fruits (0.07 serving), meat/poultry (0.78 serving) and milk/dairy products (1.14 serving) while low income toddlers and school children had the least mean intake of fruits (0.09 serving) and milk/dairy products (0.54 serving), respectively. CONCLUSION: Low socioeconomic status, as indicated by low household income, could limit access to adequate diets, particularly for older children. Parents and caregivers may need dietary guidance to ensure adequate quantity and quality of home food supply and foster healthy eating habits in children.

The purpose of this study was to analyze the relationship of nutritional status measured by the body composition and dietary nutrients intakes with calcaneal broadband ultrasound attenuation in college students. Total of 886 (462 male and 424 female) students who received health examination in May 2007 participated in this research. Participants bone status was measured by a quantitative ultrasound method and t-score was calculated via WHO guideline. For body composition measurements, body fat, height and weight were measured and BMI was calculated. Dietary data were collected by a 24-hour recall method. Based on Asia-Pacific standard of WHO, BMI was divided into 3 groups; UW (BMI < 18.5), NW + OW (18.5 $\leqq$ BMI < 25) and Obese group (25 $\leqq$ BMI). Among male students, 2.4% belong to the UW group, 45.0% to the NW+OW group and 52.6% belong to the obese group, bwhile 10.4% of female students belong to the UW group, 71.9% to the NW + OW group and 17.7% of female students belong to the Obese group. Differences among male and female students were statistically significant (p < 0.001). Students with higher BMI showed significantly higher bone health status. Male students did not show any significant differences in nutrients intakes by BMI groups while female students showed the higher intakes of energy, protein, pyridoxin, phosphorus, iron and zinc among NW + OW group than other groups (p < 0.05). The qualitative and quantitative evaluation of diet by BMI groups did not show any significant differences in both male and female students. The result of the multiple regression analyses showed that the body fat and bone status was negatively related while energy intake was positively related with the bone status. These results revealed that bone health status was positively affected by BMI but not by body fat. In conclusion, among those who are at their twenties, the period when the bone density becomes maximized, body fat may negatively affect bone health unlike during other life cycle stages.

The study was carried out to investigate the dietary attitude and hematological status of the middle school football players in Busan. The survey was conducted from September 15 to October 15, 2006 by questionnaires and data analyzed by the SPSS program. The results are summarized as follows: The weights and body mass indices of the football players were significantly lower than those of the control. Dietary attitude scores showed no significant differences between the groups. Nutrition knowledge scores of the football players were lower than those of the control. Both football players and the control preferred the sweet taste rather than others. The football players preferred the hot taste, meats, and fish rather than the control did. Serum triglyceride level of the football players was significantly lower than that of the control. Blood iron level was significantly lower in the football players than in the control. Blood urea nitrogen concentration was higher in the football players than in the control. Therefore proper nutritional education programs are required for middle school football players to improve their nutritional status and physical strength.

Sasang Constitutional Medicine (SCM) is based on the theory of Sasang (Taeyang, Soyang, Taeum, Soeum) in Traditional Korean Medicine (TKM). It is hypothesized that all of the things in the material world can be divided into the four categories of SCM. We made a new attempt to combine nutritive components, and patterns in physical activities with SCM. At first, we hypothetically divided the nutrients into 4 compartments according to SCM theory, and human body composition as well. These factors could be basically related to Sasangin Exercise Treatment (SET). Therefore, we applied sasangin theory to exercise prescription. As a research method, we hypothesized that human beings' types can be distinguished by mind and body. Mind was focused on exercise psychological aspects, and body also handled by nutrients, body compositions, body shapes, and exercise physiological aspects. For application of sasang theory to the exercise prescriptions, Taeumin as a sample sasangin was selected in this study. We concluded that in perspective of general traits, Taeumin have to reduce their carbohydrate intake volume, but greatly increase their intake of vitamins, minerals, and water in daily diet. They are also recommended exercises that can increase cardiorespiratory function and make them sweat, like endurance running, hiking, swimming, cycling, etc.

This study was performed to investigate the nutritional status associated with alcohol consumption in Korean adults men and women. The data was derived from the 2001 Korean National Health and Nutrition Survey. The number of subjects included were 6090 (Men: 2789, Women: 3031) aged 20 (equation omitted) < 65y. Men consuming moderate alcohol ((equation omitted) 24 g/day but < 48g/day) had higher intakes of energy and vitamin B groups than the ones consuming less than 24g/day. Heavy drinking men reporting more than 48g alcohol/day were observed as having 3207.2kcal of energy intake (130% of Korean RDA) and significantly elevated levels in most of the nutrients. For women drinkers, when the alcohol consumption was moderate ((equation omitted) 12g/day but 24g/day) or heavy((equation omitted) 36g/day) the energy intake was 2188.9kcal(100% of RDA) or 2627.5kcal (130% of RDA). The other nutrients protein, fat, calcium, iron and vitamin B group were also higher in women with heavy alcohol consumption. Heavy drinking women showed significantly higher weight, BMI and HDL-C. In contrast, heavy drinking men did not show any significant difference in BMI but showed significantly elevated blood pressure, HDL-C and lower serum cholesterol.

This study was conducted to figure out the differences of the BMI, blood lipids, blood pressure and nutrient intakes by serum insulin concentration among adults in Korea. Ninety-three subjects(male : n=37, female : n=56) participated in this study. The subjects were grouped by serum insulin concentrations into two groups-hyperinsulinemia group(n=17) and normoinsulinemia group(n=76). Anthropometric measurements, blood lipid profiles, blood pressure, oral glucose tolerance test, and daily nutrient intakes were analyzed. And serum glucose and insulin secretion pattern as shown through and oral glucose tolerance test were performed. BMI (p<0.05) and WHR(p<0.01) were significantly higher in hyperinsulinemic group than in normoinsulinemia group. There was no differences in fasting blood glucose level between groups, but total glucose area (p<0.001) and insulin glucose resistance(p<0.001) were significantly higher in hyperinsulinemia group than in normoinsulinemia higher in hyperinsulinemia group, but HDL-cholesterol(p<0.05), and systolic blood pressure(p<0.05) were significantly higher in hyperinsulinemia group, but HDL-cholesterol(p<0.001) was significantly lower in hyperinsulinemia group. They showed significant differences in energy, carbohydrate, potassium, riboflavin, niacin and dietary fiber intakes(p<0.05), the intake of those nutrients were low in normoinsulinemia group. Further investigation is necessary to determine the effects of amounts and types of carbohydrate and dietary fiber on serum insulin concentrations.

The purpose of this study was to investigate food habits, nutrients intakes and nutritional quality of the preschool children living in Seoul. The study was performed by analyzing a questionnaire answered by the mothers of 233 subjects aged 2 to 6 years old. A three-day dietary intakes survey, using a 24 hour recall method was used by both the mothers and teachers of the children in day care centers. Twenty eight, 65.9 and $21.8\%$ of preschool children were underweight, normal and overweight or obese, respectively. It was found that $19.8\%$ of preschool children replied that they skipped breakfast sometimes. The major reasons for skipping breakfast were 'snacks' ($38.3\%$) and 'no appetite' ($32.6\%$). The proportion of subjects having unbalanced meals was $61.6\%$. From the 24-recall survey, it was found that all nutrients intakes were higher than those of the Korean RDA except zinc. The proportions of carbohydrate, protein and fat from total calories were 56,1, 17.2 and $30.7\%$. The P/M/S ratio was 0.62 : 0.86 : 1. Nutrient adquacy (NAR), mean of nu-trient adequacy ratio (MAR) and index of nutritional quality (INQ) were considered adequate. In conclusion, the dietary intakes of children aged 2 to 6 were assumed adequate judging from nutrient intakes, although some attention should be paid to fat intake in this age group.

We examined the association between eating frequency of rice vs. bread at breakfast and nutrient and food-group intake among 1771 female college students aged 18-20 years. The frequency of main staples at breakfast and the nutrient and food group intake for the previous month were assessed with a validated self-administered diet history questionnaire. We divided main staples into rice, bread, and noodles. As the eating frequency for noodles was almost negligible, we computed the difference of eating frequency of rice minus that of bread(mean = 0.7 times/week). Among 16 nutrients examined, the difference of eating frequency correlated significantly and negatively only with fat intake, especially saturated fatty acid (SFA) (r=-0.31, p<0.001), and significantly and positively with the intake of n-3 poly-unsaturated fatty acid, iron, sodium, protein, carotene, potassium, dietary fiber, and vitamin C (r=0.08-0.15, p<0.001) after adjusting for the energy intake, the residential area, the population size, and the living status with their families. In conclusion, the more frequent intake of rice compared to bread at breakfast correlated with the higher intake of the several vitamins and minerals, and the lower intake of fat, especially SFA. The only unfavorable aspect of the rice group was the higher sodium intake.
