Korea used to be a country where individuals ate diets high in vegetables and rice, but in recent years, it has become a country where western-style diets are increasingly popular. Consequently, the age for chronicle disease, including obesity and diabetes, has become lower. The purpose of this study was to compare the dietary habits of kindergarten children between lacto-ovo vegetarian and non-vegetarian families. The data were collected from the children(n=300) at Sahmyook University Kindergarten. The results showed that non-vegetarians had higher intakes of cookies, cakes, processed foods, ice cream, and fast foods, while vegetarian children consumed high amounts of vegetables, fruits, and kimchi. The non-vegetarian children tended to have irregular meals, and ate high-fat meats such as kalbi and samgyupsal. However, the results show it is important that many children among both vegetarian and non-vegetarian families should be encouraged to have appropriate essential nutrients, because a high percentage of children in both groups appeared to have low intakes of energy, vitamin $B_2$, vitamin C, calcium, zinc, iron, etc.

The purpose of the study was to examine the changes of food and nutrient intakes of college students between 1999 and 2009. Dietary survey of 169 college students was conducted by a 24-hour recall method for three days in 2009. Food and nutrient intakes in 2009 were compared with the data from 106 students collected by the same methods in 1999. The intakes of cereals & grain products and vegetables in 2009 were lower than those of 1999, but the intakes of meats, eggs, milk & milk products, and manufactured food were higher. The intake of rice per person decreased greatly from 452.2 g in 1999 to 351.4 g in 2009 in males, and from 306.9 g to 237.2 g in females. While the intakes of protein, fat, thiamin, niacin, vitamin $B_6$, phosphorus, potassium, zinc, and cholesterol were significantly higher, the intakes of dietary fiber were significantly lower in 2009 compared to 1999 both in males and females. The nutrients consumed less than the Recommended Intakes were vitamin A, riboflavin, vitamin C, and calcium in males and additionally folate, iron, and zinc in females in both 1999 and 2009. The ratio of carbohydrate, protein and fat as energy was 61 : 15 : 24 and 60 : 14 : 26 in 1999, and 54 : 16 : 30 and 56 : 15 : 29 in 2009 in males and females respectively, showing that carbohydrate intake decreased and fat intake increased greatly. Our data suggest that nutrition education is necessary for college students to help them consume more vegetables and fruits and less fat and cholesterol.

The Korean diet, including breakfast, is becoming more Western, which could increase the risk of metabolic syndrome. Our aim was to assess whether breakfast patterns are associated with risk for metabolic syndrome in Korean adults. The study subjects (n=371; 103 men, 268 women) were employees of Jaesang Hospital in Korea and their acquaintances, and all subjects were between 30 and 50 years old. The data collected from each subject included anthropometric measurements, three-day food intake, blood pressure (BP) and blood analyses. The three breakfast patterns identified by factor analysis were "Rice, Kimchi and Vegetables", "Potatoes, Fruits and Nuts" and "Eggs, Breads and Processed meat". The "Rice, Kimchi and Vegetables" pattern scores were positively correlated with systolic (SBP) and diastolic blood pressure (DBP) measurements in men (P<0.05) and with serum triglyceride (TG) levels in women (P<0.05). The "Eggs, Breads and Processed meat" pattern scores correlated positively with weight, body mass index (P<0.05) and serum TGs (P<0.01) in men. The "Potatoes, Fruits and Nuts" pattern was associated with lower risk of elevated BP (OR 0.49, 95% CI 0.28-0.88) and fasting glucose levels (OR 0.51, 95% CI 0.26-1.00). In contrast, the "Eggs, Breads and Processed meat" pattern was associated with increased risk of elevated TGs (OR 2.06, 95% CI 1.06-3.98). Our results indicate that reducing the consumption of eggs, western grains and processed meat while increasing fruit, nut and vegetable intake for breakfast could have beneficial effects on decreasing metabolic syndrome risk in Korean adults.

BACKGROUND/OBJECTIVES: The association between dietary patterns and depression has been reported but the results have been inconsistent. This study was conducted to investigate the association between dietary patterns and depression in middle-aged Korean adults. SUBJECTS/METHODS: The participants were selected from a community-based cohort, a subset of the Korean Genome and Epidemiology Study. Depression was assessed using the Korean version of the Beck Depression Inventory (BDI) and those with a BDI score ${\geq}16$ were defined as having depression. The subjects' food intakes over the year preceding the survey were estimated by using a validated semi-quantitative food frequency questionnaire. Dietary patterns were identified by using factor analysis. Multiple logistic regression was used to assess the association of dietary pattern with depression. RESULTS: Among 3,388 participants, 448 (13.2%) were identified as having depression. We identified two major dietary patterns: 'Healthy' dietary pattern was characterized by high intakes of vegetables, soybeans, mushroom, seaweeds, white fish, shellfish and fruits and a low intake of white rice. 'Unhealthy' dietary pattern was characterized by high intakes of white rice, meats, ramen, noodles, bread and coffee and a low intake of rice with other grains. Compared with subjects in the lowest quartiles, those in the highest quartiles of the healthy dietary pattern had a significantly lower odds ratio (OR = 0.59, 95% CI: 0.42-0.82, P for trend = 0.0037) after adjusting for potential confounders. In contrast, the unhealthy dietary pattern was negatively associated with depression (OR = 1.65, 95% CI: 1.19-2.28, P for trend = 0.0021). CONCLUSION: This results suggest that a healthy dietary pattern (rich in vegetables, soybeans, mushroom, seaweeds, white fish, shellfish, and fruits) is associated with low risk of depression. Whereas an unhealthy dietary pattern (rich in white rice, meats, ramen, noodles, bread, and coffee) is associated with a high risk of depression in middle-aged Korean adults.

The ascorbic acid contents of 101 food items were analyzed by HPLC to provide database to estimate dietary intakes of ascorbic acid of Korean. Foods with high contents of ascorbic acid were green vegetables, citrus fruits, strawberry, kiwi, and fruit juices. This analysis data of ascorbic acid contents in some food items showed significant deviations compared with other Food Composition Table. Ascorbic acid content in soups were lower than those of raw foods by about 57%. The ascorbic acid contents in blanched or seasoned after blanching vegetables and boiled or steamed meals turned out to be decreased by about 52.3% and 47.5%, respectively, but the degrees were varied with the kind of foods as well as cooking methods. The ascorbic acid intakes from 18 most frequently consumed meals in Korea were determined to be about 1/2 of Food Composition Table according to this analysis data. The results showed the importance of accurate food database in assessing nutrient intake levels of population.

This study was conducted to investigate the dietary pattern of children with unbalanced diet in school feeding. Children who eat only what they like among elementary school students were selected for this survey. The general characteristics, nutrition knowledge, eating behavior, food intake frequencies and food preferences of the subjects were investigated compared with control group. The subjects were consisted of a total of 160 children : 92 male students(unbalanced-diet group, 46; control group, 46), and 68 female students(unbalanced-diet group, 34; control group, 34). There was no significant difference in nutrition knowledge between the unbalanced-diet group and the control group. Dietary behavior of control group turned out to be more desirable than that of the unbalanced-diet group. In addition, 68.7% of the unbalanced-diet group and 13.8% of the control group hated to eat vegetables. The result of food intake frequency indicates that the control group turned out to be higher in their intake of fish, cereals, vegetables, seaweeds, fats & oils and Kimchi compared with unbalanced-diet group. Intake frequency of minerals and vitamins of the control group was higher than that of the unbalanced-diet group. On the other hand, the unbalanced-diet group turned out to be higher in sugar intake. Children showed the greatest preference of fruits. The unbalanced group turned out to prefer sugar and beverages more than the control group. These results suggest that the desirable dietary habits of children should be formed with the help of nutrition education designed for behavior modification.

Objectives: This study examined the effects of nutrition education on the nutritional status, including eating habits and quality of life in gastric cancer patients undergoing a gastrectomy. Methods: Thirty one out-gastric resection patients at C University Hospital in Gwangju, Korea were enrolled in this study. The patients received an individualized nutritional counseling session, and the effects were assessed before and after a 3-month nutrition education intervention. Nutrition education for gastric cancer outpatients included the dietary guidelines (e.g., food intake), the level of nutrient intake, and nutrition support. Results: The patients had significantly improved serum albumin and hematocrit levels after nutrition education. Of the dietary habits, the meal time and amount of food compared to the first education were increased significantly. Of the changes in the food intake frequency, fish and meat, and vegetables and fruits intake were increased, but not at a statistically significant level. The score of eating habits related to the gastrectomy was improved significantly after nutrition education from 31.7 to 34.5. The composite scores for the quality of life were also improved significantly after the nutrition education program. Conclusions: The nutrition education for gastric cancer outpatients may be crucial and efficient for improving their lifestyle.

The purpose of this study was to compare the nutrient intake and diet quality of postmenopausal osteoporotic women to those of control subjects, and to investigate the relationship among diet quality and bone mineral density in postmenopausal women. In this study, we classified the subjects into the postmenopausal osteoporotic women (n =38) and control (n = 43) according to their lumbar spine bone mineral density and age. Dietary intakes, anthropometric measurements and dietary quality indices were measured and evaluated. The average age of osteoporotic and control group were 60.4 yrs and 58.3 yrs, respectively and there was no significant difference. Body weight, body mass index of osteoporotic group were significantly lower than those of control group. The average energy intake of osteoporotic and control group were 1243.3 kcal and 1475.8 kcal, respectively and there was a significant difference. The osteoporotic group consumed significantly lower quantities of protein, plant protein, vitamin A, vitamin $B_1,\;vitamin\;B_2$, folate, vitamin C, calcium, animal calcium, plant calcium, iron and zinc compared to the control group. The osteoporotic group consumed significantly lower of food, vegetables, mushrooms, fruits intakes compared to the control group. In the diet quality, protein, vitamin A, vitamin $B_1,\;vitamin\;B_2$, folate, vitamin C, calcium, iron, Zinc nutrient adequacy ratio (NAR) of osteoporotic group were significantly lower than that of control group. Mean adequacy ratio (MAR) of osteoporotic and control group were 0.63 and 0.78, respectively and there was significant difference. To evaluate nutrient density, Index of nutritional quality (INQ) was calculated by dividing nutrient content per 1,000 kcal of diet with RDA per 1,000 kcal. The average dietary variety score (DVS) of osteoporotic and control group were 22.4 and 33.2, respectively and there was significant difference. DVSs of pulses (p<0.01), seeds (p<0.01) and vegetables (p<0.05) in osteoporotic group were significantly lower than those of the control. In conclusion, postmenopausal osteoporotic women had lower protein, vitamin A, folate, vitamin C, calcium, iron zinc intake quality and vegetables, mushrooms, fruits DVSs than those of the control. Therefore, to promote skeletal health enough energy and food should be consumed, and the maintenance of vitamin and mineral balance by increasing of vitamin A, folate, vitamin C, calcium, iron of intakes are very important.

As the elderly population has increased in the advanced countries, food intake, relationship of nutrient intake and disease has become major problem in the aged. To investigate the dietary behaviors and the preference of food of the elderly for developing meal planning, the study was conducted through survey questionnaires including 24-hr dietary recall, dietary behaviors, food preference and frequency of food intake to 352 elderly (104 male and 248 female) who were more than 60 years old and living in Seoul. Most of subjects ate three meals regulary and the most preferred taste was sweet and the less preferred taste was sour. Dietary behaviors according to educational level were shown that the skipping meal time and duration time of one meal were significant difference in educational level. Most of the elderly subjects like kimchi and soybean paste soup. The more educated elderly were preferred milk. The reason of dislike of milk was bad flavor and diarrhea. Most of them who graduated from university and high school selected fishes because of good for health primary, otherwise no educated, elementary school and middle school graduated elderly selected vegetables primary. Meats, fishes, seaweeds, mushrooms, fruits, milk and milk products, eggs and vegetables intakes of total elderly subjects were significantly positively related to educational level. With respect to milk and milk products intakes, cheese, yogurt (curd) and milk intake of elderly was significantly negatively related to age. Therefore education for developing desirable dietary behaviors and improving the meal patterns should be in forced to elderly, especially who had poor educational background in order to manage the meal planning and to care for their health in the later life.

BACKGROUND/OBJECTIVES: This study was conducted to examine disparities in food and nutrient intakes based on family types identified among 1,856 participants who were the Korean elderly people in the 6th Korea National Health and Nutrition Examination Survey (KNHNES) excluding those who were currently practicing the diet therapy. SUBJECTS/METHODS: We separated the subjects into two groups: living alone (LA, n = 638) and living with a spouse (LS, n = 1,218). We also examined the disparities of dietary quantity and quality of those two groups using complex sampling design general linear regression analyses (CS GLM). RESULTS: In the LA group, there was a higher percentage of females and average age in LA group was higher than the participants in the LS group. Household income and education level were significantly lower in LA compared to those of LS. The frequencies of skipping meals were higher in LA. LA's food and nutrient intakes showed lower consumption of vegetables, fruits, seaweeds, and of most nutrients. Even after adjusting for the confounding factors, the consumption of vegetables, seaweeds, carbohydrates, potassium, riboflavin, and vitamin C showed lower in LA than LS. Moreover, LA's nutrient intake ratios compared to the KDRIs were lower which turned out to be similar to their nutrient intakes. CONCLUSIONS: These results show that dietary behavior and food intake of the elderly are associated with family types. Frequently skipping meals and less dietary variety are more common with elderly persons who were living alone. Therefore, it is necessary to integrate the supplementary food programs and nutrition education programs for the elderly living alone.
