The consumption of fruits and vegetables that have high polyphenol content has been previously associated with a reduced risk for cardiovascular disease. We investigated the effects of onion peel extract on plasma total antioxidant capacity, lipid peroxidation, and leukocyte DNA damage. This study was a randomized, double-blind, placebo-controlled, crossover trial. Healthy female subjects received either onion peel extract or placebo (dextrin) for two weeks, underwent a 1-week washout period, and then received the other treatment for an additional two weeks. After two weeks of onion peel extract supplementation, the total cholesterol level, low-density lipoprotein cholesterol level, and atherogenic index significantly decreased (P < 0.05). No changes were observed in activities of erythrocyte antioxidant enzymes or levels of lipid peroxidation markers following onion peel extract supplementation. Additionally, no significant difference was found in plasma antioxidant vitamin (retinol, tocopherols, carotenoids, and coenzyme Q10) levels or ex vivo $H_2O_2$-provoked oxidative DNA damage after onion peel extract supplementation. The present interventional study provides evidence of the health benefits of onion peel extract and demonstrates its effects in modulating lipid profiles in healthy young Korean women.

Objective : Recently many kinds of food therapies have sprung up to prevent or manage disease and to promote health. Seeing Korean history, the Korean medical doctors have been applying food therapy based on the thought that the dietary sources were as important as the medicine. Therefore, in this study, we designed a mobile edutainment game prototype with the goal of providing education about healthy food knowledge for users who belongs to different constitutional types. Materials and Method : We adopted the Sasang Constitutional Medicine as the medical background knowledge for our edutainment game design. Based on the user study, we developed the process of edutainment system which is composed of 'My game', 'My constitution', and 'My food'. Among the whole process, we developed a prototype for the core module - the 'My game' part. This prototype used a jumping game for mobile devices that is composed of training, level 1 and level 2 stages. Results : From the target user evaluation, it was proved that 1) in terms of the learning effect of healthy diet, the edutainment game we developed has a significant advantage over the conventional learning media. 2) after playing the edutainment game, the good and bad food identification accuracy based on picture and text format were increased by 44% and 42% respectively, and 3) target users perceived enjoyment while using this prototype, as well as showed positive intention to use this game as edutainment tool in the future. Conclusion : We designed and developed mobile edutainment game prototype to educate healthy food knowledge based on Sasang Constitutional Medicine. Through user evaluation, we proved that our prototype enhanced healthy food knowledge and that user accepted the prototype as a beneficial edutainment tool.

This study was designed to provide the basic data of an effective nutrition education for desirable lifestyle and dietary habits to improve the nutritional status for the elderly by investigating health-related lifestyle, dietary habits, nutritional knowledge, and food intake of the elderly. The subjects included 58 elderly men and 146 elderly women. 35.8% had no more than an elementary school education. Most subjects (54.4%) were widows/widowers. Most subjects (71.0%) made over 150,000 won. 52.5% of subjects lived in houses. Smoking, drinking, exercise, the average sleeping time were significantly difference between the gender (p<0.05). In terms of dietary habits, our results showed that 80.9% of respondent eat regularly meals, including breakfast (83.5%). Both sexes prefer soft and salty food. Women enjoys more spicy and salty food compared with men and then shows meaningful difference (p<0.05). Their favorite meals are soup, stew, salad and boiled vegetables. Compared to women, men have a higher rate of correct answers about questions related to nutrition knowledge as showing significantly difference (p<0.05). In a study of dietary habits, they take in carbohydrates with the highest percentage and following by vegetables and fruits. The amount of meat, first and egg they eat is more than the previously. Eating meat is higher men as showing significant difference (p<0.05). In summary, nutritional status for the elderly shows healthy lifestyle and diet about half of those and most them try to live healthy life in future. It is hope that the elderly may need to learn proper nutrition knowledge for healthy lifestyle and nutrition education and counseling for building up healthy lifestyle and desirable dietary habits. Furthermore, it is necessary to start work to establish a baseline nutritious evaluation for the elderly and at a time to study the development of standard eating tool proven reliability and validity, consequently to provide a basic framework for the evaluation of nutritional status.

We investigated the association between dietary habits/food group consumption patterns and early risk of metabolic syndrome (MetS), a main cause for metabolic disease. Study participants were recruited from the health promotion center in Dong-A University Hospital and public advertisement. Study subjects (n = 243, 21-80 years) were categorized into three groups: Super-healthy (MetS risk factor [MetS RF] = 0, n = 111), MetS-risk carriers (MetS RF = 1-2, n = 96), and MetS (MetS $RF{\geq}3$, n = 27). Higher regularity in dietary habits (breakfast-everyday, regular eating time, non-frequent overeating, and non-frequent eating-out) was observed in the Super-healthy group than in the MetS-risk carriers, and particularly in the MetS subjects. The relationship between food group consumption patterns and MetS-risk related parameters were investigated with adjustment for confounding factors. Fruit consumption was positively associated with HDL-cholesterol, and tended to be negatively associated with waist circumference, triglyceride, LDL-cholesterol, and insulin resistance (IR). The consumption of low-fat meats and fish, and vegetables was negatively associated with hs-CRP. Specifically, the consumption of seafoods belonging to the low-fat fish was negatively associated with fasting glucose, hs-CRP, and interleukin (IL)-6. Anchovy/dried white baits consumption was negatively associated with fasting insulin and IR. Green-yellow vegetables consumption was negatively associated with fasting insulin, IR, and hs-CRP. On the other hand, sugars and fast-foods were positively associated with LDL-cholesterol. Additionally, fast-foods consumption was positively associated with hs-CRP and IL-6 levels. In conclusion, dietary habits/food group consumption patterns are closely associated with MetS-risk related parameters in Koreans. It may suggest useful information to educate people to properly select healthy foods for early prevention of MetS.

The principal objective of this study was to analyze Swede's perceptions of Asian food using a means-end chain method, which may contribute to our understanding of new markets for a food industry interested in globalizing Korean food. With the Means-end chain method, one can determine the cognitive structures built in consumer's minds, which are developed by connecting attributes of product, consequences, and values. The attributes of Asian food that are most positively perceived by Swedes are 'fresh vegetables', 'low-fat', 'light meat and seafood', 'exotic ingredients', 'not expensive' and 'unknown food'. The consequences of eating Asian food connected to these attributes are 'healthy', 'tasty', 'good way to save money' and 'curious'. Finally, Swedes expect to enjoy a value of 'achievement' at the end. Based on the result that 'unknown food' attribute is connected to 'achievement' value, Swedes are assumed to be attracted by the fact that Korean food is 'unknown food'. However, the effect of the 'unknown food' attribute will fade away with time; therefore, stressing Korean food's status as a 'healthy' food, which can be attributed to its use of 'fresh vegetable' and 'light meat and seafood' ingredients and 'low fat' cooking method may be effective as a long-term strategy for making Korean food attractive. The 'healthy' consequence is connected to Swedes' perception of the value 'achievement' and simultaneously to their perception of the value 'belonging and love/sense of belonging'.

This study examined the effects of eating alone, meal type, and dietary lifestyles on healthy eating capability of one-person households. We analyzed the mediation effects of weekly frequencies of each meal type taken by one-person households between eating habits such as eating alone and dietary lifestyles of one-person households and healthy eating capability. We also analyzed data from the 2019 Food Consumption Behavior Survey using a sample of 688 one-person households. Factor analysis, latent profile analysis, structural equation model analysis was conducted; direct and indirect effects of independent variables were tested using bootstrap method. The major results were as follows. Frequency of eating alone was about 10 times a week on average; one-person households had home-made meals about 12 times a week, for restaurant meals, 4 times, for delivered/take-out food, 0.39 times, and for other types, 0.44 times. Weekly frequencies of eating alone and meal types taken by one-person households were significantly different among the different socio-demographic groups. Dietary lifestyle was classified into four classes: traditional, health ignorant, food lifestyle ignorant, and balanced. Eating alone and dietary lifestyle had a significant effect on weekly frequency of each meal type. Frequencies of eating alone, balanced dietary lifestyle, and taking home-made meals had a positive direct effect on healthy eating capability, and frequency of taking delivered or take-out food and food consumption ignorant lifestyle had a negative direct effect. Eating alone, balanced and traditional dietary lifestyles had a positive indirect effect through the meal type; however, watching Mug-bang had a negative indirect effect.

This study was conducted to identify the major dietary patterns of Korean adult men and to examine the relationship between subjective stress perception and these dietary patterns using data from the 2014~2016 Korean National Health and Nutrition Examination Survey (KNHANES). Of the 23,080 total subjects, adult men between the ages of 19 and 64 who did not take the questionnaire or answer the questions relating to depression, and cases where the daily energy intake was less than 500 kcal or more than 5,000 kcal in the Food Frequency Questionnaire were excluded. This left a total of 3,464 subjects who were included in the final analysis. We performed a factor analysis based on the yearly mean intake frequency of 41 food groups to identify the major dietary patterns. Three major dietary patterns were identified (factor loading >0.3), including the 'Healthy pattern', 'Processed meat pattern', and the 'Alcohol pattern'. The 'Healthy pattern' was characterized by higher intake of beans, tofu, vegetable, fish, and fruits. The 'Processed meat pattern' was characterized by high consumption of processed meats and instant foods. The 'Alcohol pattern' was characterized by a higher intake of alcohol. As a response to the subject's subjective perception of stress, the most answered 'a little' according to age, marital status, occupation, income, residential area, smoking status, drinking status, and exercise status. People whose diets followed the 'Processed meat' and 'Alcohol' patterns had significantly higher scores on subjective stress perception compared to people following the 'Healthy pattern'. To manage subjective stress, it is more effective to maintain health by relieving stress through a healthy method that combines healthy eating and exercise rather than following an unhealthy diet as characterized by the 'processed meat' and 'alcohol' dietary patterns.

The purpose of this study was to determine the recognition of body image and food behavior factors according to the BMI. The subjects of this study were 242 7th grade students resided in San Francisco area. The degree of recognition for self-estimated physique of subjects by gender and by race showed no significant differences by gender but significant differences by race, showing that 20.0% was considered as underweight in Asian and 7.5% was considered as underweight in White students. This showed the same tendency as actual physique status (BMI). Also, the ratio of being recognized as more than overweight was 17.3% in Asian, 23.3% in Hispanic, and 13.4% in White students. In case of female students, the ratio of dieting experience was 63.3%, and 49.3% of White students and 63.3% of Hispanic students experienced dieting. In case of students answered not healthy, their body weight were significantly higher than those answered as healthy, and the BMI was also over 19, showing significant differences. Thus cases that answered as not healthy had greater body weight and BMI. Also it showed that frequent dieting experience is related to higher height and weight. The analysis of food behavior factors perceived by body shape showed that the group perceived itself as overweight consumed more 'fast food' but had low scores in 'vegetables' intake, with frequent intake of 'soda' and tendency to 'overeat'. Also, the tendency for 'balanced life' was significantly lower and for skipping breakfast was significantly higher, suggesting problematic food behavior.

This study was performed to compare nutrients intake and levels of three elements (iron, copper and zinc) in the plasma of breast cancer patients to those in healthy controls. Patients (n = 97) and their age-matched healthy control groups (n = 97) participated in the study. A semi-quantitative food frequency questionnaire specifically formulated to evaluate the consumption of nutrients was used to estimate dietary intake. Only plasma was taken from the 20 patients and their age-matched healthy control group. Plasma concentrations of iron, copper, zinc, ratio of Cu/Zn were measured in both groups. Results showed that patients consumed significantly lower protein, fat, iron. Plasma level of copper and ratio of Cu/Zn were significantly higher in patients compared to those of controls. In conclusion, change of trace elements in plasma might be useful and significant as biomakers involving the initial process. And these results imply that trace elements status is a factor related to breast cancer risk and suggest that proper intake of those nutrients is required for cancer prevention.
