  • Bakery nutrition labeling has been implemented in the company, but most consumers have no idea about it due to lack of promotion of the product nutrition labeling information or do not have a big interest in it. As a result, various studies based on the forecast about changes in consumption patterns of the bakery market due to nutrition labeling information are needed. Especially nowadays, when buying bakery products the involvement of consumers in health and nutrition is growing. So, we need to understand that nutrition labeling information makes any causal relationship between consumer attitude and confidence, purchasing behavior in bakery products. It can be said to be a very important research. For that reason, I think this research will help to settle and activate the nutrition labeling information system for the rational purchasing decisions of consumers in the bakery market. In addition, this research could be a base material for various marketing strategies.

  • This study was performed to investigate the relationship between diet quality and food cost and identify the effects of food cost on healthy diet among Korean adult. Among the subjects of 2001 National Health and Nutrition Survey 1,641 men and 1,765 women aged from 30 to 49 years were selected and their information of dietary intakes, socio-demo-graphic information, and anthropometric data were analyzed. For the analysis, subjects were classified to quartile based on their daily food cost. Food guidelines provided by Korean Nutrition Society was regarded as a model of healthy diet. Subjects in the lowest quartile of food cost consumed inadequate amount of food from all food categories of the guidelines. Many subjects in the highest quartile not only satisfied the recommended amount of the Food Guide but also seemed to overeat high energy density foods. Even in the highest quartile, about 90% of subjects did not satisfied recommended amount of dairy products. According to the calculated cost of healthy diet, the average cost did not seem to be more expensive than the current mean food cost of the subjects, and most cost-sensitive food intake was observed in the meat fish beans eggs category. The implications of study results were: 1) all the high cost diets did not indicate the high quality of diet, 2) most practical matter of healthy diet in low income group seemed whether they could afford the expense of meat and fish, 3) nutrition education was required to most subjects for healthy diet.

  • This study investigated micro-mineral content in human milk along with nutritional intake of lactating women. Milk samples were collected from 33 healthy lactating women and mineral levels were analyzed. Copper, zinc, manganese and selenium were analyzed. The factors that affect the mineral levels in human milk were also investigated longitudinally from 2-5 days to 12 weeks postpartum. Concentrations of manganese and selenium didn't differ significantly within the lactation period. the levels of copper and zinc declined linearly over the first 12 weeks of lactation. Statistically significant quadratic trends were observed in zinc concentrations. There was no significant correlation between maternal age and mineral concentrations throughout the lactation period. In addition, no significant differences were found between the primipara and the multipara for mineral concentrations in human milk.

  • The productivity and 13 influencing variables in 14 conventional hospital foodservice systems the total direct and non-direct labor hours required to produce and serve the total number of patient meals plus the number of cafeteria meals. Human resource variable significantly influencing the productivity level was the labor cost. As this index decreased, the meals served per human hour worked increased. System resource variables correlating significantly with productivity were the length of cycle menu, the ratio of staff meals, and modified patient meal ratio. As the length of cycle menu and the ratio of modified patient meal decreased, more meals were produced per human hour. However, as staff meal ratio increased, the meals served per human hour worked increased. The stepwise regression analysis suggests that around 53% of the variance in productivity is explained by labor cost.

  • Objectives: This study was undertaken to compare dietary life of the elderly living alone and in a family, and to compare differences based on gender, for the 2013-2016 Korea National Health and Nutrition Examination Survey (KNHANES). Methods: The subjects included 2,612 elderly people aged over 65 years who participated in the health survey, health examination and nutrition survey. Subjects on a diet therapy were excluded. This study analyzed the general characteristics, dietary habits, daily energy and nutrient intakes, CPF ratio, estimated average requirement (EAR), nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR), index of nutrient quality (INQ), and food consumption of the elderly living alone and in a family. We also compared the differences based on gender. Results: Daily intake of food, water, dietary fiber, potassium, retinol, and riboflavin were low in the male elderly subjects living alone. The elderly living with family revealed higher NAR and MAR as compared to the elderly living alone. Although all MAR values were <1, the elderly living alone had lower values. Considering the intake of food, the consumption of seaweed, fish and shellfish, and oils (animal) was higher in elderly men living with families, whereas women living with families consumed more vegetables, fruits, seaweeds and seafood, as compared to their counterparts living alone. Furthermore, analyzing the foods consumed by the elderly people living alone, female subjects consumed more seaweed, milk and animal oil as compared to male subjects. Conclusions: The results of this study indicate that the elderly living alone have poor nutrient intake as compared to the elderly living with families. Based on this research data, we recommend that it is necessary to improve the health and nutritional status of the elderly living alone.

  • Metabolic syndrome (MetS), which is heavily dependent on dietary and lifestyle practices, is prevalent in Korean adults. Because dietary practices are unique for each race, nationality, and culture, it is important to identify Korean adult dietary practices that are associated with MetS. Macronutrient intake patterns were analyzed and compared across health status using the 2007-2008 Korean National Health and Nutrition Examination Survey data (8,143 adults who had dietary data and biomarkers related to MetS). Although intake levels were different by age, gender, and health status, carbohydrate intake was high and fat intake was low among Korean adults. The carbohydrate energy ratio was higher and the fat energy ratio was lower for subjects > 60 years old who were diagnosed with diabetes, hypertension, or MetS than those in other age groups. The main source of fat from food differed depending on the group. These results demonstrated that macronutrient intake patterns were different between age, gender, and health status subgroups. Hence, it is recommended that nutritional policy and practices aimed at controlling MetS should be based on the dietary characteristics of the target group.

  • This survey was conducted to compare food habit and food service satisfaction of high school students in urban and rural areas. The questionnaires were collected from 130 students in Daejeon and 140 in Geumsan. 19.8% of students skipped breakfast because of no time(48.7%), just habit(28.2%), no appetite(20.5%), for weight control(2.6%). The dietary behavior of rural students was better than city in taking snacks and light meal(p<0.05). For health they concerned highly about nutrition label expiration date of processed foods(72.3%) and least in considering nutrition than taste & price(37.9%). The satisfaction of food served was highest in nutrition(3.31), and taste(3.28), smell (3.23), color(3.03), temperature(3.02). The food service satisfaction of rural students was higher than city in proper temperature(p<0.001), nutrition(p<0.01), color(p<0.001). The satisfaction of rural students was higher than city in quantity of bap & side dishes, quality of food materials(p<0.001). The satisfaction of rural students was higher than city in convenience of dining hall, rapidity of food distribution, offer of nutrition information, sanitation of utensils & meals(p<0.001). It is suggested that school dietitian in city should be more concerned about sanitary food service based on students' dietary life & preference.

  • Chronic liver diseases, including cancer, are characterized by inflammation and elevated serum ferritin (SF). However, the causal-relationship remains unclear. This study used primary rat hepatic stellate cells (HSC) as a model to investigate effects of physiological SF concentrations (10, 100 and 1000 pM) because HSCs play a central role in the development and progression of liver fibrosis. Physiological concentrations of SF, either horse SF or human serum, induced pro-inflammatory cytokine $IL1{\beta}$, IL6 and $TNF{\alpha}$ secretion in rat activated HSCs (all p<0.05). By contrast, treatment did not alter activation marker ${\alpha}SMA$ expression. The presence of SF markedly enhanced expression of Grp78 mRNA (p<0.01). Furthermore, transient knock down of Grp78 by endotoxin EGF-SubA abolished SF-induced $IL1{\beta}$ and $TNF{\alpha}$ secretion in activated HSCs (all p<0.05). In conclusion, our results showed that at physiological concentrations SF functions as a pro-inflammatory mediator in primary rat HSCs. We also provide a molecular basis for the action of SF and identified Grp78-associated ER stress pathways as a novel potential therapeutic target for resolution of fibrosis and possible prevention of liver cancer.
