  • The purpose of this study was to investigate the eating patterns, nutrient intakes, blood levels, and health status of male college students in Seoul according to body mass index (BMI). In this study, we classified subjects into normal weight (n=240), under weight (n=11), and obese (n=46) groups according to BMI. The weight and BMI were significantly higher in the obese group compared to other groups (p<0.0001). The obesity was associated with overeating and frequent eating. The under weight group showed significantly higher consumption of fast food, snacks, and fried foods compared to the other groups (p<0.05). The intakes of milk, meat, fish, eggs, and fried food and preference ratios were higher in the obese group (p<0.05). The male college students in this study showed insufficient intakes of calories, vitamin C, folic acid, and calcium. The plasma LDL-cholesterol levels in the obese group were higher compared to the other groups. In conclusion, intake of nutrients among male college students is found to be insufficient and requires nutritional education. The under weight group showed regular eating habits and increased nutrient intake. The obese group was shown to need more exercise with higher intakes of vegetables and fruits.

  • The objective of this study is to provide direction in the improvement of sodium labeling in an effort to reduce consumption. We surveyed confirmation and importance of food labeling and nutrition information and we also analyzed the willingness to pay on new nutrients labeling. Consumers checked the sell-by-date, product name, method of intake, but not nutritional information. They also checked for calories and carbohydrates but they were not interested in sodium, sugar, and trans fat which are health hazard nutrients. It is necessary to improve nutrition labeling, because consumers are experiencing difficulties in obtaining sodium information under the nutrition labeling system. Consumers will pay about 0.66% more if new sodium labeling is introduced. In conclusion, food labeling system can be improved by smooth and efficient access of information. for health-hazard nutritional components, such as sodium, it is important to introduce policies that reduce their intake. This can be done by providing consumers with clear and concise information. The social costs of high sodium intake could be reduced, hence improving the national health.

  • Food hygiene and nutrition is a serious public health concern. It is the responsibility of providers and duty of consumers to ensure that hygienic and nutritious food is being served and consumed respectively. A cross-sectional study was conducted among 384 students to assess the perception of hygiene and nutrition of food in the restaurant of Pokhara Valley, Nepal. Data were collected by a self-administered questionnaire. Two-third of the respondents were female in this study. The taste was the most common reason for the consumption of food in the restaurant. In the same way, more than two-thirds of the respondents considered restaurants' food for not having a balanced diet. Around one-third of the respondents consumed food high in vitamins and minerals, protein, carbohydrate, and calories in restaurants. Around two-thirds of the respondents considered hygiene of food in restaurants as slightly hygienic. More than two-thirds of the respondents considered unhealthy to eat food in the restaurant. The study found the association between education status, family type with a taste of the food. Proper awareness, promotion activities for the healthy nutrition lifestyle & food safety education is highly recommended at the local level.

  • The present study was aimed to investigate the effect of dietary supplementation of $\beta$-carotene on vitamin A metabolism in ethanol-fed rats. Sprague-Dawley rats weighing 190~210g were fed a liquid diet containing 36% of total calories as ethanol for 6 weeks. The pair-fed control rats(1BP group, 2BP group) were given an isocaloric amount of diet containing sucrose instead of ethanol on the following day. Additionally, the liquid diet, contained different levels of $\beta$-carotene(1BE group: 2.1, 2BE group: 21mg/L liquid diet). Body weight gains and food efficiency ratios of ethanol groups were lower than those of pair-fed groups. This effect did not change with dietary supplementation of $\beta$-carotene. The levels of plasma and hepatic retionl were decreased after chronic ethanol feeding, but the values in 2BE group were higher than in 1BE group. The content of hepatic retinoic acid tended to increase in proportion to $\beta$-carotene supplementation. There results suggest that ethanol consumption may affect the vatamin A methabolism and reduce the conversion of $\beta$-carotene to retinol in rats.

  • This study was conducted to investigate the uses of Aster scaber. The survey methodology employed was a questionnaire, which was used to interview 272 (37.8%) males and 448(62.2%) females from the Seoul and Kyunggido areas. The main results are as follows: 40-50 years old like and eat Aster scaber more frequently than 10-30 years old. The most popular reason provided for the preferance of Aster scaber was good health benefits. People indicating a dislike for Aster scaber had generally fewer previous experiences of eating this plant. Respondents who regularly ate healthy foods preferred prepared Aster scaber to others foods(p < .001). The main purchasing place was traditional markets and supermarkets. The main cooking method was boiling with addition of seasoning. Aster scaber was purported as having the following characteristics "low calories and thus great as diet food'(4.03), 'ability to prevent adult disease'(3.95), 'high in vitamins and minerals'(3.89), and 'high fiber content which prevented constipation'(3.85). However, it was not associated with 'astringent taste'(3.51) and was regarded as 'fat accumulation restrainer and remover of heavy metal'(3.53). Recognition and eating experience was low for Aster scaber kimchi and rice bread, bread, sauce and Aster scaber added health drinks. However opinion of its taste was regarded highly.

  • This study was carried on the analysis of nutritional value and preference between the plain gruel (Hyun Jook) and the experimental gruel (Tarak Jook, Jangkook Jook & Chajohonhab Jook) in order to improve the quality and variety of menu patterns of gruels for the patients requiring soft diet. The results obtained are as follows: 1. In comparing the calorie coutent of each gruel, Tarak Jook, Jangkook Jook, and Chajohonhab Jook had more calories-82.7%), 39.3% and 12.4% respectively-than Hyun Jook. Additionally, in the case of protein content, Tarak Jook, Jangkook Jook and Chajohonhab Jook showed higher values than Hyun Jook by 270%, 137% and 28.3% respectively. 2. The preference for each experimental gruel compared with Hyun Jook, as a function of taste, color and concentration of the gruels was shown to be insignificant. But the color and concentration did effect the preference level for each gruel. Hoverer, patients did have a preference for particular gruels: Jankook Jook, Tarak Jook, Chajohorhab Jook in descending order. 3. Overall, 65.6% of the patients requiring soft diet thought gruel was only for the sick 57.1%) thought the reason for gruel as a soft diet was that it could be digested easily 75.8% of the patients disliked gruel and their frequency of intake was very low 78.8% did not know more than 5 types of gruel. Hoverer patients did prefer a loose gluel(48.4%). In couclusion, awareness of gruel as a soft diet for patients and its intake as one not to meution as a normal diet was low.
