BACKGROUND/OBJECTIVES: Recently, there has been an increased interest in the importance of family meals on children's health and nutrition. This study aims to examine if the eating habits and eating behaviors of children are different according to the frequency of family dinners. SUBJECTS/METHODS: The subjects were third-grade students from 70 elementary schools in 17 cities nationwide. A two-stage stratified cluster sampling was employed. The survey questionnaire was composed of items that examined the general characteristics, family meals, eating habits, eating behaviors, and environmental influence on children's eating. The subjects responded to a self-reported questionnaire. Excluding the incomplete responses, the data (n = 3,435) were analyzed using ${\chi}^2$-test or t-test. RESULTS: The group that had more frequent family dinners (${\geq}$ 5 days/week, 63.4%), compared to those that had less (${\leq}$ 4 days/week, 36.6%), showed better eating habits, such as eating meals regularly, performing desirable behaviors during meals, having breakfast frequently, having breakfast with family members (P < 0.001), and not eating only what he or she likes (P < 0.05). Those who had more frequent family dinners also consumed healthy foods with more frequency, including protein foods, dairy products, grains, vegetables, seaweeds (P < 0.001), and fruits (P < 0.01). However, unhealthy eating behaviors (e.g., eating fatty foods, salty foods, sweets, etc.) were not significantly different by the frequency of family dinners. CONCLUSIONS: Having dinner frequently with family members was associated with more desirable eating habits and with healthy eating behaviors in young children. Thus nutrition education might be planned to promote family dinners, by emphasizing the benefits of having family meals on children's health and nutrition and making more opportunities for family meals.

Purpose: This study investigated the salt and sodium content of lunch meals served at foodservice center for children in Gyeongsan-si, Gyeongsangbuk-do. Methods: Five foodservice centers for children registered at Center for Children's Foodservice Management were investigated for salt and sodium content and salt content contributing rate per meal. Results: Average salt content of every meal was $1.78{\pm}0.54g$, and average sodium content was $680.99{\pm}175.97mg$. The 98 of 100 meals served in 5 foodservice centers for children exceeded the dietary reference intakes for Koreans' recommendation for adequate intake of sodium per meal of 333 mg. The highest sodium content was 1,369.85 mg. Samples from lunch meals were classified into 14 food items and investigated for one serving size, salinity, salt and sodium content. Total average salinity was 0.31%, kimchi (0.49%), followed by soup (0.45%), hard-boiled foods (0.39%), stir-fried foods (0.39%), and fresh-vegetables (0.32%). Total average salt content was 0.39 g, the most salty dishes were one-dish rice noodles, followed by soup (0.65 g), hard-boiled foods (0.49 g), stir-fried foods (0.48 g), and broth stew (0.43 g). Samples from lunch meals were classified into 6 menu groups, including cooked rice, one-dish rice noodles, soup stew, main dish, side dish, and kimchi. Contributing rate for total average salt content was high in one-dish rice noodles (48.97%), soup stew (38.47%), main dish (27.28%), side dish (21.02%), kimchi (18.56%), and cooked rice (3.95%). Conclusion: These results can be useful for reducing total dietary sodium content to less than 333 mg in children who are provided lunch meals at foodservice centers. To achieve this goal, development of low-sodium recipes, and nutrition education for foodservice employees is required.

This study was performed to compare the anthropometric and the food and nutrient intake of the adolescents between urban areas and islands in south Kyungnam and to identify their nutritional problems. A questionnaire survey was distributed among 383 middle school students for the food and nutrient consumption and other nutritional attitudes including socioecomonic status. The height and weight of the students were measured as well. Socioeconomic status, such as income, educational level, and jobs of the urban students parents was better than that of the island students. There was no significant difference in height between the students of both areas, but the body weight of the urban male students was far heavier than that of the other group. It is very interesting to note that the energy intake of the urban male students was much lower than that of the island male students. The students of the two areas consumed more protein, Vit B$_1$, Vit B$_2$, niacin and Vit C than the recommended daily allowances(RDA) but the intake of Ca, Fe, Vit A was less. As to the sources of animal fat, the urban males consumed much more. Regarding the taste preference, the study shows that urban male students are more likely to choose sweet, salty and soft tastes than island male students. In the case of female students, although island students prefer a rather hot taste, urban students are more likely to prefer sweet and soft tastes. The favorite foods of urban students are meat products, fastfoods, chocolate, cheese and milkshakes, while foods like cooked rice with assorted vegetable are the favorite of the island students. In general, the preference degree for meat products and fruits rates higher than for vegetables. Conclusively the urban students had a tendency of being obese and the intake of all nutrients by the urban adolescents was much lower than that of the islanders. In this study, the cause can be found in significant differences in consuming animal fat, of taste preference and of choosing favorite food. Accordingly a nutritional intervention or educational program is required to adjust the imbalanced intake of some nutrients for the adolescents in this province.

Food is crucial for the nutrition and survival of humans. Taste system is one of the fundamental senses. Taste cells detect and respond to five basic taste modalities (sweet, bitter, salty, sour, and umami). However, the cortical processing of taste sensation is much less understood. Recently, there were many efforts to observe the brain activation in response to taste stimulation using functional magnetic resonance imaging (fMRI), magnetoencephalography (MEG), and optical imaging. These different techniques do not provide directly comparable data each other, but the complementary investigations with those techniques allowed the description and understanding of the sequence of events with the dynamics of the spatiotemporal pattern of activation in the brain in response to taste stimulation. The purpose of this study is the understanding of the brain activities to taste stimuli in sensory and affective aspects and the reviewing of the recent research of the gustotopic map by functional brain mapping.

This study aimed to examine the health-related lifestyle habits and eating behaviors according to gender, ethnicity, and residence type of university students in Yanbian, China. Self-administered questionnaires were collected from 302 university students. Of the male students, 12.1% and 42.0% were in the underweight and overweight groups, respectively, and of the female subjects, 21.3% and 16.3%, were in those respective groups. More male than female students preferred the overweight body somatotype. In contrast, about 49.4% of female students were hoping to be underweight, and female students had more obvious difficulties with body somatotype perception, whereas their exercise frequency and time spent exercising per day were much less than those of male students. More Chinese than Korean-Chinese subjects exhibited regular eating habits, which included eating at the same time everyday and at the same frequency per day; these habits were, accompanied by generally healthier lifestyle habits regarding regularity of activity and exercise time. Self-boarding students had a significantly higher BMI ($23.7{\pm}5.1kg/m^2$) and were more likely to be overweight (43.5%) as compared to students who lived in a dormitory or with family. Salty taste was preferred by Chinese students more than Korean-Chinese students, and greasy taste was preferred by Korean-Chinese students as compared with Chinese students. This study found that inherent and environmental factors are related with the dietary behaviors of university students in Yanbian, China. Further studies are required to elucidate the structural elements of family life and the sociocultural factors associated with dietary behaviors in Yanbian.

In this study, we compared diet related attributes such as food taste preference, food consumption frequency and nutrition intake between elderly residents in their 80's of areas in Jeollanam-do that are well known for longevity and those of a part of Seoul. Structured in-depth interviews were conducted by trained interviewers on 125 consented subjects (67 Jeonnam and 58 Seoul). Differences of groups were tested using Chi-square tests for nominal or ordinal data and t-tests and ANOVA tests for ratio data. The elderly from Jeonnam tended to sleep longer, express emotion more freely, and interact with others more often than those from Seoul. The elderly tended to prefer sweet or salty tastes, which might be highly related to serious health problems. The most frequently consumed foods were napa cabbage kimchi (2.19 times/day) and multigrain rice (1.99 times/day). Elderly from Jeonnam tended to consume garlic, milk, beans and roasted barley/corn teas less often; whereas, they consumed porridge, dried radish greens, potato, fermented fish, dried fish, pork rib, pork belly, soybean paste soup, soybean paste/Ssamjang, other kimchis, pickled vegetables, snacks, cookies, and green/black teas more often than elderly residents from Seoul. Differences in nutrition intake between the regions were greater than differences between the perceived levels of household economic status. NAR and INQ for folate were lower among elderly from Jeonnam than those from Seoul, while those for protein, vitamin C, niacin, vitamin $B_6$ were higher. The study results indicated that elderly from Jeonnam engaged in a more diverse diet than the elderly from Seoul.

Background: Changes in dietary practices are known to be associated with changes in the health and disease pattern of a population. This study aimed to qualitatively explore the perception of colorectal cancer patients regarding causes of colorectal cancer and the influence of diet. Materials and Methods: Twelve respondents from three major ethnicities in Malaysia were selected from the quantitative study on dietary pattern and colorectal cancer carried out earlier in this study. In-depth interviews (IDI), conducted from April until June 2012, were mainly in the Malay language with additional use of English and continued until the saturation point was reached. All interviews were autorecorded so that verbatim transcriptions could be created. Results: Causes of colorectal cancer were categorized into internal and external factors. The majority of respondents agreed that there is an association between Western foods and colorectal cancer. Malaysian traditional diet was not related to colorectal cancer as less preservative agents were used. Malaysian diet preparation consisting of taste of cooking (spicy, salty and sour foods) plus type of cooking (fry, grilled and smoked) were considered causes of colorectal cancer. All respondents changed their dietary pattern to healthy food after being diagnosed with colorectal cancer. Advice from doctors regarding suitable food for colorectal cancer was useful in this regard. Conclusions: Eating outside, use of food flavoring ingredients and preservative agents were considered to be the main factors causing colorectal cancer. All respondents admitted that they changed to a healthy diet after being diagnosed with colorectal cancer.

The purpose of this study was to identify the eating habits and dietary consciousness of urban residents according to socioeconomic characteristics. The survey was administered by the nationwide 690 adults in February 2001. The survey was conducted by a questionnaire that was composed of 20 items. The results of this study show that 56.8% of the subjects had breakfast everyday and majority of them ate cooked rice (57.4%) or rice with mixed grain and bean (33.0%) as stable food for breakfast. 73.6% of the subjects ate out less than 5 times a month and, most of them preferred Korean dishes to Western dishes. The majority of the subjects had a meal regularly and they ate dinner abundantly with gusto compared to breakfast and lunch. Mean values of preference (5 point scales) for snack, salty and hot taste, and processed food were 3.07±0.89, 2.75±0.83, 3.28±0.90, 2.69±0.84 respectively. Interest (4 point scales) in eating safe and fresh food, balanced diet, and overeating calorieㆍsugarㆍsaltㆍfat were 3.26±0.66, 2.83±0.70, 2.89±0.75, respectively. As the purpose of eating, 44.8% of the subjects placed emphasis to supply nutrition but 16.6% put emphasis on physiologic desire. About half of the subjects needed to change their own eating habits. As improvement of their eating habits, the majority of them answered ‘balanced diet’. There were significant differences in eating habits and dietary consciousness of the subjects by socioeconomic characteristics. As the age goes down and education level goes up, they had wrong eating habits generally. For occupation, housewives had right eating habits but students were not. For interest in food and nutrition, male, 20' age-group, students and over college graduation group were worse than the other groups within each socioeconomic characteristic. Consequently, nutrition education for them is needed preferentially, also their socioeconomic characteristics must be considered in nutrition education.

A nutrition education program for teachers and caregivers of the preschool children can be most effective when it is based on a comprehensive needs assessment dealing with sociodemographic factors, dietary habits, and nutrition. The purpose of the present study was to investigate current dietary habits and nutrition knowledge of the teachers and caregivers of the day-care centers. Two hundred forty two teachers and caregivers were administered a questionnaire which was designed to ascertain informations on sociodemographic data, dietary habits and nutrition knowledge. Dietary habits of the teachers were found to be significantly different by sociodemographic variables; breakfast skipping/meal irregularities (age, p=0.011); frequency of snacking (education level p=0.031); preference for salty taste(age, p = 0.000, marital status p=0.038); preference for sweet tarte (age p=0.009); preference for vegetables (income level p=0.050); frequency of eating out (age p=0.028, marital status p=0.001); frequency of coffee drinking (age p=0.019). Daycare center teachers' nutrition knowledge level was found to be less than adequate expecially on nutrients that are liable to be deficient in young growing children and their food sources. Proportions of the teachers who answered correctly to the questions on foods rich in vitamin A, iron content of milk, bioavailability of calcium in plant foods were as low as 20.2%-54.5%. The most frequently used sources of nutrition information were mass media such as TV, radio, newspaper and magazines. Only 2.9% of the subjects reported that they obtain nutrition information from health professionals such as nutritionists/dietitians, physicians, and nurses. These findings are applicable at the planning and implementation stages of various nutrition programs for the improvement of dietary habits and nutrition knowledge of the teachers and caregivers of the daycare centers. Further studies are needed to investigate the effects of teachers' dietary of habits and nutrition knowledge on food habits of young growing children.
