Purpose: This study examined whether there was a difference in the nutrients and food intake of young children depending on their lunch places. Methods: The dietary survey data of the fifth Korea National Health and Nutrition Examination Survey (2010 ~ 2012) were used. The children were grouped into either a child care center lunch group (n = 728) or home lunch group (n = 592) and their nutrients and food intakes were compared. Results: No differences in the 24-hr energy intake and energy intakes from lunch and dinner according to the lunch places were observed. The percentage of breakfast energy was lower in the child care center lunch group, whereas the percentage of snack energy was higher. In children aged 3 ~ 5 years, the sodium, potassium, and vitamin C intakes were high in the child care center lunch group. The 1 ~ 2 years and 3 ~ 5 year old children's vegetable intake from lunch was significantly higher in the child care center lunch group than in the home lunch group. Children aged 3 ~ 5 years in the child care center lunch group consumed more beans and fish at lunch. The adequacy of nutrients and food diversity of child care center lunch appear better than home lunch. Conclusion: Parents and care providers need to make efforts to use diverse foods, such as vegetables and fish, in children's meals to provide balanced diets and promote healthy eating behaviors to their children.

Objectives: This study investigated the improvement of food habits and eating behavior of cancer patients during treatment through the continuous nutrition counseling and monitoring. Methods: Thirty cancer patients during treatment were participated in this study, and the first nutrition counseling and the first and second monitoring were conducted after 2-3 week intervals. Results: As a result of the nutrition counseling and monitoring, all patients improved to a great extent to consume 3 meals a day. The frequency of having breakfast was significantly increased with the nutrition counseling and continuous monitoring as well. The meal fixed quantity was stabilized and the eating speed slowed down as more nutrition counseling were done. The snack intakes of patients did not show any significant difference after the nutrition counseling but showed a slight decline after the monitoring. The frequencies of eating out and a late-night meal significantly decreased after the monitoring. The intakes of fish, meat, vegetables, milk and fruits needed for a well-balanced diet significantly increased as more nutrition counseling were done. The intakes of processed food were significantly decreased after the nutrition counseling and the intakes of fast food were significantly decreased as more nutrition counseling were done. The water intake of patients also significantly increased. In the eating behavior related to health, the frequency of drinking alcohol significantly decreased after nutrition counseling consultation and no patients had dietary supplements after the first monitoring. Conclusions: These results suggested that continuous nutrition counseling is effective in improving eating habits of cancer patients.

This study was conducted to investigate the difference of perception about nutritional problems and food intakes and nutrition knowledge score and realities of nutrition education between parents and preschool teachers. This research can be summarized as follows: there was the statistical difference of perception (${\chi}^2$= 52.451, p = 0.000) about nutritional problem of preschoolers between parents and preschool teachers. Parents (56.4%) and teachers (58.5%) identified eating only what they want as the most common nutritional problem of children, but they had different perception about the other problems. To parents, "No nutritional problem" (16.3%) is the second and "Overindulgence of processed food" (11.1%) is the third problem of preschoolers. To teachers, "Overindulgence of processed food" (23.8%) is the second and "Obesity" (14.3%) is the third problem. The perception on food intakes of preschoolers was statistically different in meats (${\chi}^2$= 8.892, p = 0.030), fish (${\chi}^2$= 32.241, p = 0.000), beans (${\chi}^2$= 14.770, p = 0.005), vegetables (${\chi}^2$= 12.706, p = 0.013), fruits (${\chi}^2$= 14.438, p = 0.006) and milk & dairy products (${\chi}^2$= 28.591, p = 0.000) between parents and preschool teachers. However, nutritional knowledge was not different between parents and preschool teachers. While 96.6% of preschool teachers felt that it was necessary to educate preschoolers, only 41.5% of them said that they fulfilled nutrition education, showing that nutrition education was not adequately carried out on the spot. Therefore providing basic materials through which nutritional management guidance and proper nutrition education for preschoolers can be carried out by investigating and analyzing knowledge on their nutrition and meal guidance activities for preschooler teachers and parents.

To increase both iron and enhancers for iron absorption through diets should be a basic strategy to sufficiently provide increased iron for pregnancy. Previous studies reported that iron intakes of Korean pregnant women were short and their iron status deteriorated as pregnancy progressed. However, there is little data about the bioavailability of dietary iron during pregnancy. Therefore, this study was conducted to determine the changes of dietary iron intakes, its bioavailability and iron status during pregnancy longitudinally in Korean women. A total of 151 pregnant women in their first trimester of pregnancy voluntarily participated. Among them, 72 women finished the research protocol during the second trimester and 55 did it during the third trimester. Dietary intakes of total iron, both non-heme and heme iron, as well as enhancers, both MPF (meat, poulty, and fish) and vitamin C, increased significantly as pregnancy progressed. As the results, bioavailability of dietary iron and iron absorbed increased significantly as pregnancy progressed. However, the amount of iron absorbed at each trimester did not meet considerably the iron needed during pregnancy. All five indices examined in the study, Hb level, Hct, serum concentrations of ferritin and sTfR (soluble transferrin receptor), and sTfR: ferritin ratio, showed that iron status of the subjects deteriorated as pregnancy progressed. The rate of anemia of the subjects increased as pregnancy progressed although more than 80% of the subjects took iron supplements after the 20th week of pregnancy. These results imply that it is needed to provide more iron especially, heme iron and dietary enhancers to prevent the deterioration of iron status during pregnancy. Future research on bioavailability of supplemental iron should be performed to determine the iron balance precisely.

This study aimed to examine nutritional status and similarities of diets between Vietnamese female immigrants and Korean spouses and dietary changes of Vietnamese females after immigration. Subjects were 608 couples visiting 13 medical centers for the Cohort of Intermarried Women in Korea from November 2006 to November 2007. Anthropometric and biochemical measurements were obtained and dietary intakes were assessed using one-day 24-hour recall. Sixty-eight percent of wives answered there have been changes in their diets and consumptions of meats, fish, dairy products, vegetables, and fruits increased after immigration. Energy intakes of wives and spouses were 1491.7 kcal and 1788.8 kcal, respectively, showing most couples (80.1%) consumed less than the Korean estimated energy requirements. More than half of the couples were below the Korean estimated average requirements of zinc, vitamin $B_2$, and folate. The correlation coefficients between couples ranged 0.15-0.38 for unadjusted, 0.22-0.35 for per 1000 kcal, and 0.21-0.40 for energy-adjusted, respectively. The proportions of couples in the same quartiles of each nutrient intake and in the same answers of each question of Mini Dietary Assessment were about 30% across nutrients and around 50% across questions. The length of residence is related to similarities of nutrient intakes between couples: similarities decreased after 3 years of residence in Korea. In conclusion, nutritional intakes of inter-married couples were inadequate although wives reported that their dietary intakes increased after immigration. Inadequate nutrient intakes of wives were partly explained by similar diets between couples because these wives without enough adjustment to Korean culture were more likely to follow what their spouses ate. Findings from this study may be helpful to improve the nutritional status of inter-married couples and make policies and programs for them. A follow-up study should identify factors affecting inadequate nutritional status of intermarried couples and similarities of their diets.

BACKGROUND/OBJECTIVES: Women's bone health status is closely related with environmental factors and lifestyle factors. The purpose of this study is to evaluate the dietary risks of osteoporosis and osteopenia for Korean postmenopausal women. SUBJECTS/METHODS: The data from 1,433 subjects from the 2010 KNHANES were used and divided into three groups: normal, osteopenia, and osteoporosis group using bone mineral density (BMD). Nutrient intakes and food intake frequency were evaluated. Logistic regression analysis was applied to determine the odds ratios for osteoporosis and osteopenia. RESULTS: The RNI percentage of each nutrient and food intake frequency from 12 food groups decreased as bone mineral density status deteriorated. Risk for osteoporosis of low calcium (Ca) intake, under the EAR, showed an odds ratio of 2.13(95% CI; 1.26-3.61, P < 0.05). Higher intake frequency showed preventive effect from osteoporosis compared to lower intake frequency in such food group as dairy products (ORs 0.40, CI 0.21-0.75), beans (ORs 0.49, CI 0.29-0.83), seaweeds (ORs 0.55, CI 0.32-0.94), fish (ORs 0.56, CI 0.32-0.98), and fruits (ORs 0.42, CI 0.23-0.79) after adjusting for age. CONCLUSION: To prevent osteoporosis in later life, sufficient Ca intake and more frequent intakes of foods containing Ca such as dairy products, beans, fish, seaweeds, and fruits, which help in Ca absorption, should be stressed for Korean postmenopausal women.

This study examined the nutritional information using the nutrition labels of gimbap sold at convenience stores and evaluated nutritional adequacy compared to dietary reference intakes for Korean adolescents. Thirty gimbaps (triangular gimbaps and regular gimbaps according to the main ingredients of vegetables, fish, and meat) were purchased at five convenience stores of different brands with many stores in Korea. The food and nutrition labels of the gimbaps were investigated, and nine minerals were analyzed using inductively coupled plasma-mass spectrometry (ICP-MS). The average price of gimbap was 1,906.7 won, and average energy was 292.0 kcal, and the protein content was 15.5% of the recommended intake for Korean male adolescents aged 15~18 years. The mineral content ranged from 6.9% for zinc to 39.0% for selenium. Except for sodium and selenium, the energy, protein, and mineral content did not meet 1/3 of dietary reference intakes for adolescents. For the index of nutritional quality (INQ), calcium and zinc were the lowest in the triangular and regular gimbap, respectively. The INQ of potassium was significantly higher in triangular gimbap with vegetables. The content and INQ of selenium were in regular gimbap with fish, and the zinc INQ was in regular gimbap with meat. Overall, gimbap sold in convenience stores has a high sodium content, and the contents of energy, protein, and minerals, except selenium, are insufficient for a single meal.

This study was designed to find out the effects of $\omega$-3 and $\omega$-6 polyunsaturated and saturated fatty acid from prenatal to growing period on the brain growth and behavioral development of rats. Rats(Sprague-Dawley strain) were fed experimental diets-fish oil, corn oil or beef tallow-with different contents of $\omega$-3 and $\omega$-6 fatty acids throughout the prenatal and lactational period and up to 10 weeks of age. DNA and RNA concentration of rat brain were determined at 0, 3, 6 weeks of age and choline and acetylcholine concentrations were analyzed at 10 weeks of age. When the rats were 7 weeks of age, position reversional test in a Y-shaped water maze for 4 weeks was measured. The experimental results obtained are summarized as follows. Food intakes were significantly lower in fish oil group and body weight gain was low in the group fed beef tallow and the groups fed fish oil and corn oil were somewhat good. Food efficiency ratio was not significantly different among the groups. Brain weight was not affected by the fatty acid composition of experimental diets and DNA and RNA concentration of the rat brain were consistently maintained at the same level. It was not different significantly among the dietary groups in the DNA and RNA concentrations of the rat brain during the experimental period. The acetylcholine concentration in the fish oil group was somewhat higher than the other groups. The position reversional test in a Y-shaped water maze showed a significant difference the score of test among the experimental groups. The score of the rats fed the fish oil diet was significantly higher than the other groups and the concentration of acetylcholine in brain were too. Therefore the correlatin between the Y-shaped water maze test score and the acetylcholine concentratin in the brain was found. Above finding support the content that dietary fatty acid composition does not affect to the brain cell number and cell size but the behavior development is influenced. Therefore, the improvement of behavior development is required the effective usage of finny tribe.

The digestibility of organic matter (OM), crude protein (CP), ether extract and amino acids of a cassava root meal and rice bran diet, without (Basal) and with inclusion of fish meal (FM) or fresh (FSB) or ensiled (ESB) shrimp by-product in growing pigs (Large White$\times$Mong Cai) fitted with post-valve T-caecum (PVTC) cannulas was studied in a $4{\times}4$ change-over experiment. Significantly higher ileal digestibility of OM in the basal and FM diets and lower ileal digestibility of CP in the basal and ESB diets were found (p<0.05). Total tract digestibilities of OM and CP of diet ESB were lower (p<0.05) than in the other diets. The apparent ileal digestibilities of most amino acids were higher (p<0.05) in diets FM, FSB and ESB than in the basal diet. There was no difference (p>0.05) in the ileal digestibility of individual amino acids between diets FM, FSB and ESB, except for threonine, alanine and glycine. The estimated apparent ileal digestibility of individual amino acids in ensiled shrimp by-product was lower (p<0.05) than in fresh shrimp by-product and fish meal. In conclusion, as a result of the reduced daily intake of the diets containing shrimp by-products and lower ileal and total tract digestibility of both fresh and ensiled shrimp by-products complete replacement of fish meal cannot be recommended. The ensiled shrimp by-product was inferior nutritionally compared with fresh shrimp by-product. However, lower daily feed intakes of both the FSB and ESB diets suggest that the replacement should only be made partially, in order not to reduce the overall performance.

The Purpose of this study was to investigate the eating habits, nutrition and dietary fiber intakes of middle school students from urban areas, Jinju city and rural areas, Hadong and Namhae Gun in Gyeongnam province. Data were collected by using a survey questionnaire. The result of this study are as follows: In the respects of eating habits, the eating habits of girl students ware worse than those of boy students Regardless of region and subjects, the intakes of energy, calcium, iron, riboflavin, dietary fiber were poor. In all the regions the intakes of dietary fiber was far less than $20\~25g$ of daily intakes level. Mental education should also be emphasized to form teenagers' self-identity and the sense of value. Also, the nutritionists of each school should try to focus on the composition of group meals containing fish, vegetables, Kimchi and boiled rice and cereals, not satisfying with the group meals centered on hygiene. Health and nutrition depends on the food people take, teenagers' health is the basis of their future health. The continuous study about teenagers' eating habits and dietary fiber needs to be emphasized.
