Rhinitis and sinusitis are among the most common medical conditions in Korea, as well as Western societies. Environmental factors may influence both rhinitis and sinusitis; however, the role of dietary factors in rhinitis and sinusitis is not clear. The present study aims to compare the dietary habit, food consumption frequency, and food preference of elementary school students with or without rhinitis and sinusitis. The demand of their parents for an education program for the dietary prevention against rhinitis and sinusitis was also examined. The survey was conducted with a total of 200 subjects recruited from two elementary schools located in Gyeonggi area of Korea. The subjects consisted of 101 students with rhinitis and/or sinusitis (RS group) and 99 without rhinitis and sinusitis (control group). The students of the RS group were more likely to have habits of eating-out and street food use, to consume bean, peanut, walnut, almond, yogurt, egg, snack, and French fries frequently, and to prefer the types of foods prepared by stir-frying and deep-frying than the control group. The parents who recognized 'school nutrition teachers or food/nutrition-majored specialists' as the most appropriate educator for the dietary education program in the RS group (48.5% of their parents) were less than those in the control group (67.7% of their parents). The present study suggest that students with rhinitis and/or sinusitis may be different from those without the disease(s) in their dietary habit, frequently consumed foods, and preferred type of foods. More epidemiological, intervention, and laboratory studies are needed in order to elucidate the role of dietary factors in the development and prevention of rhinitis and sinusitis, which will have a significant implication to public health.

Kimchi is the most well-known Korean traditional food, but it is also the main leftover of school lunch and dinner menus. This study aimed to familiarize teenagers with kimchi through school meals and to increase their daily kimchi intake, ultimately by appealing to the young generation's taste. A questionnaire survey was conducted in the Ansan area to examine student's acceptability of kimchi and their attitudes toward kimchi. Approximately 65% of males and 67% of female students liked the moderately fermented and pungent taste of kimchi. Kimchi served in school meals was regarded as nutritional but cheap. Approximately 72% of male and 82% of female students responded that they liked menu items using kimchi. Approximately 48% of students responded that menu items using kimchi in schools are not diverse. Students preferred meat as an ingredient in kimchi. The preferred cooking methods were stir-frying and frying, whereas boiling was the least favorite. Based on the survey results, ten kimchi menu items had been developed. The suitability of the menu was evaluated by students and cooks. Six kimchi items, including Kimchi mixed with rice, chicken, soybean sprouts, Kimchi cheese rice, stewed beef ribs with kimchi, rice topped with kimchi curry, kimchi cheese meat roast, and kimchi udong were considered appropriate for school meals, whereas kimchi kangchong, kimchi topokki, kimchi stew with surimi, and frozen Pollack kimchi soup were not suitable as menu items. Kimchi topokki was not accepted by students, while kimchi kangchong was not accepted by cooks. Cooks judged the suitability of a menu item by the cooking process and cooking times, whereas students judged an item by its sensory preference. Approximately 63% of students responded that kimchi intake has increased by participating in the development of kimchi dishes.

Food is essential for sustenance and reflects a country's identity, making it crucial to identify the cultural needs for effectively localizing Korean food. This study surveyed 825 adults from four continents (eight countries) to examine their preferences, familiarity, and attitudes toward Korean food. Significant correlations(p< .001) were found between the familiarity and preference for Korean food, with variations observed across continents. Among the representative Korean food items, the average preference score was 4.67, and the purchase/recommendation intention score was 4.88. Seven items received above-average ratings (e.g., gogi-deopbap and kimchi-bokkeumbap), while some items showed high liking but low purchase/recommendation intention (e.g. dak-jjim and galbi-jjim). In addition, items such as gimbap and tteokbokki had high purchase/recommendation intention but low liking, and kimchi and vegetable foods etc. received low liking and purchase/recommendation intentions. In terms of the preferred meat according to the cooking method and seasoning, beef respondents preferred grilled·stir-fried and soup·stew·hot pot cooking methods, while pork or chicken respondents preferred grilled·stir-fried and frying methods. Soy sauce was the most preferred seasoning for all meat responses, followed by red pepper paste. These research findings provide fundamental data for developing Korean food products, segmented by continent.

Objectives : Atractylodes rhizomes, which have been widely used to treat gastrointestinal disorders, consist of numerous chemical compounds. Polyacetylenes are the parts of characteristic compounds of importance required to understand the therapeutic properties of Atractylodes rhizomes. It is necessary to understand the physicochemical and pharmacological properties of polyacetylenes in the Atractylodes rhizomes.Methods : The literatures from 1970 to January 2016 were searched using Korean and international electronic databases. The chemical structures of polyacetylenes were drawn by structure-drawing software.Results : The reported polyacetylenes were classified by their chemical skeletons and original resources, and their physicochemical and pharmacological features were discussed. Polyacetylenes with skeletal moieties were reported, such as diene-diyne types (two double and two triple carbon-bonds), triene-diyne types (three double carbon bonds and two triple carbon bonds), and monoene-diyne types (one double carbon bonds and two double carbon bonds), with various functional groups. Atractylodin was most frequently reported from many Atractylodes species. Atractylodin-related polyacetylenes showed chemical instability in both high and freezing temperatures. Processing of the Atractylodes rhizomes by stir-frying with bran could affect the contents of polyacetylenes and their bioavailability in vivo. Several polyacetylenes showed structure-related anti-inflammatory activities and gastrointestinal activities.Conclusion : Polyacetylene compounds in Atractylodes rhizomes were based on three chemical backbones and showed diverse physicochemical and pharmacological features. The present study provides structural, physicochemical, and pharmacological information of polyacetylene from Atractylodes rhizomes. This information provides fundamental data for further research.

With changing socio-economic environments, there have been some changes in the Korean diet. One of major changes is the increasing fat intake. Based on the current trend of increase, it is important to understand factors related to fat intake levels. Objective of this study was to find out the differences in food consumption patterns, demographic characteristics, and other socio-economic factors among three groups of households. The households were devided into three groups by percentage of fat energy intake to total energy intake such as less than 15%(Group 1), from 15% to 25%(Group 2), and more than 25% (Group 3). Among 1, 987 households, the numbers in Group 1, Group 2 and Group 3 were 792(39.6%), 902(45.4%), and 293(15.1%), respectively. The mean size of family was 3.44 person per households for total survey household, 3.42 for Group 1, 3.54 for Group 2, and 3.21 for Group 3. More than 60% of families living in the rural area belonged to Group 1(p<0.05). Group 3 had most educated food preparers and more income than other groups(p<0.05). Group 3 showed higher intake of all nutrient analyzed except carbohydrate (p<0.05). Other than calcium and vitamin A for Group 1, and vitamin A for Group 1, and vitamin A for Group 2, all nutrient intake analyzed for three groups were more than 75% of Korean recommended dietary alowances. Mean fat intakes for Group 1, Group 2, and group 3 had highest amount of intake for all food groups. According to food group analysis, Group 3 had highest amount of intake for all food groups except vegetables. Group 3 consumed more than 10 times of meats compared to Group 1. Group 3 had more dishes prepared by baking, deep-fryng, stir-frying, and pan-frying other two groups. Processed foods were used most frequently in Group 3. Other diet and related factors were analyzed also. These results showed that the amount of fat consumed by Korean households varies widely. Households with high fat energy intake had tendency to reside in the largy city, and to have heigher education level and more income than other groups. They eat less vegetables, use more cooking methods using oils, and use more processed foods. To ensure a proper intake of fat, there should be two separate ways of approach for high fat energy group and low fat energy group, since they are different in many ways.
