The results obtained by survey on 599 respondents of different age groups for preference of 84 prepared foods were subjected to statistical principal component analysis, factor analysis, analysis of variance, scheffe verification, and discriminant analysis so as to find a structure of preference for foods. The results may be summarized as follows: 1. The results of the factor analysis indicate that 84 prepared food items may be classified into 3 groups and that by knowing an indvidual's preference to one prepared food, one can presume his preference to the others in the same group without carrying out actual test. 2. The results from an analysis of variance showed that most of primary school children extremely liked snacks, seniors liked Korean cooking, primary school children and collegians had weaknesses for western cookings while kindergarden children and adults over 50 years old disliked them.

Korean vegetable dishes-Na mul are indigenous and popular foods for a long time, and have been eaten by not only the common people but also the royale people in the ordinary meal and customary affairs. Grains are principal item of diet for Koreans and additions of Na mul in diet provide the nutritional minerals and vitamins. Especially vegetable oils in seasoning played the important role in nutrition balance. This manuscript historically investigate the Korean vegetable dishes-especially Na mul, Seng chae, Ssam, and the vegetables, additional ingredients and seasonings. 1. Foreign vegetable were introduced very actively. As the result of it, the more variety of vegetables are available. 2. Vegetable oils such as sesame oil, perilla oil, roasted sesame seed and pine nuts, etc were widely used for seasonings. 3. Seng chae dishes had been prepared with more than two different kinds of vegetables. Seasonings are used from the various sources, and combination of ingredients and development of condiments are expected to research further. 4. Ssam foods basically used uncooked vegetables, but steaming and boiling are also common methods.

BACKGROUND/OBJECTIVES: Most consumers are able to recognize allergenic foods. However, the frequency of checking such foods is reportedly low, resulting in higher prevalence of food-related allergic reactions in Korea compared to other countries. Thus, this study was performed to investigate the overall perception of allergenic food labeling and its practice level in food manufacturing company employees. SUBJECTS/METHODS: The survey was administered to food safety employees and food development teams at food companies located in metropolitan areas. A total of 399 (93.8%) valid samples were used in the final analysis. Statistical analyses, including Frequency Analysis, t-test, Anova, PCA (Principal Component Analysis), and Pearson Correlation Analysis using SPSS ver. 21.0, were performed. RESULTS: The correct answer rate in the analysis of allergy-related knowledge level ranged from 15.0% to 89.7%. Analysis of differences in allergy-related perception by knowledge level showed significant differences in introduction of a food recall system, strengthening of relevant laws and regulations, content labeling, description of substitutional food, and differentiated package by age. CONCLUSIONS: It can be concluded that labeling of allergenic foods should be made easier and more convenient for checking by employees, developers, and consumers, and it is necessary to provide contents through the development of publicity, guidelines, or APP along with labeling.

The purpose of this study was to find out the taste adjectives of Korean cooked rice, noodles, porridges and rice cakes as well as to analyze the relation between the taste adjectives of foods. We gathered and chose 36 related Korean adjectives for expressing not only the taste but also the smell of foods. Subsequently, we performed a sensory evaluation for 18 Korean foods with 20 trained panelists in order to check the proper adjectives when they tasted the foods. The often selected taste adjectives were 'sweet', 'tasty', 'sticky' and 'soft' among 36 taste adjectives. The PCA was performed to summarize the taste adjectives for each of the 18 foods. The principal components explained 50.94 % of the total variance. The adjectives 'spicy' and 'refresh' were closely related to one another in the positive direction of PC1. In contrast, 'weak', 'hard' and 'sticky' were closely related to one another in the negative direction of PC1. PC2 was marked by 'hard' and 'spicy', which were located in the positive direction. In contrast, 'weak' and 'soft' were located in the negative direction. PC3 was marked by 'nutness', 'bitter' and 'spicy', which are associated with bibimbab, conveying a high degree of correlation among them in a positive direction. In contrast, 'cool', 'sour' and 'refresh' were located in the negative direction.

This study was performed to find natural foods with high anti-dementia effects from natural plant resources which have been used for mental health. We screened inhibitors of prolyl endopeptidase which could be implicated in the processing of Alzheimer's disease, the principal part of dementia. One hundred natural foods were examined for prolyl endopeptidase inhibitors. Out of them, methanol extract of Acorns and Raspberry inhibited more than 90% of prolyl endopeptidase activity at 40 ppm. Also, methanol extract of Walnut inhibited 73% of prolyl endopeptidase activity at the same concentration. Therefore, the result suggests that these natural foods may have the potential to be used for preventing and treating dementia like Alzheimer disease.

BACKGROUND/OBJECTIVES: Little is known about the dietary patterns (DPs) of women during pregnancy. The present study aimed to identify the DPs of pregnant Malaysian women and their associations with socio-demographic, obstetric, and anthropometric characteristics. SUBJECTS AND METHODS: This prospective cohort study included 737 participants enrolled in Seremban Cohort Study between 2013 and 2015. Food consumption was assessed using a validated 126-food item semi-quantitative food frequency questionnaire (SFFQ) at four time-points, namely, pre-pregnancy and at each trimester (first, second, and third). Principal component analysis (PCA) was used to identify DPs. RESULTS: Three DPs were identified at each time point and designated DP 1-3 (pre-pregnancy), DP 4-6 (first trimester), DP 7-9 (second trimester) and DP 10-12 (third trimester). DP 1, 4, and 7 appeared to be more prudent diets, characterized by higher intakes of nuts, seeds & legumes, green leafy vegetables, other vegetables, eggs, fruits, and milk & dairy products. DP 2, 5, 8, and 11 had greater loadings of condiments & spices, sugar, spreads & creamer, though DP 2 had additional sweet foods, DP 5 and 8 had additional oils & fats, and DP 11 had additional tea & coffee, respectively. DP 3 and 6 were characterized by high protein (poultry, meat, processed, dairy, eggs, and fish), sugars (mainly as beverages and sweet foods), and energy (bread, cereal & cereal products, rice, noodles & pasta) intakes. DP 9 had additional fruits. However, DP 12 had greater loadings of energy foods (bread, cereal & cereal products, rice, noodles & pasta), sugars (mainly as beverages, and sweet foods), and good protein sources (eggs, nuts, seeds & legumes). Malays were more likely to have lower adherence (LA) for DP 1 and 10 than non-Malays. DP 2, 8, and 11 were more prevalent among Malays than non-Malays. Women with a higher education were more likely to have LA for DP 10, and women with a greater waist circumference at first prenatal visit were more likely to show LA for DP 11. CONCLUSIONS: DPs observed in the present study were substantially different from those reported in Western populations. Information concerning associations between ethnicity, waist circumference and education with specific DPs before and throughout pregnancy could facilitate efforts to promote healthy dietary behavior and the overall health and well-being of pregnant women.

Sea-divers(woman) are living in coastal villages and their principal daily work is to dive into sea water in order to get sea-weeds, pearls etc. They are able to be stayed inside the water for a relatively long period and at the same time have a hard physical work during the period. Besides these works, they work also on farms and in homes in their rest time. Hwa-Jeon-Min('fire-field' farmers) are living in higher mountainous areas (plateau areas) and they burn off the ground for cultivation and obtain the crops on which they are living. Usually, they are far apart from cities and markets. The above mentioned two groups are special social groups in this country, consequently are interested in their food and nutritional habbits. The summarized surveyed results are as follows (See the Tables 1, 2, and 3). 1. In case of Sea-divers(woman): a. Staple foods are cereals, vegetables, and fishes and shell-fishes. These foods occupy 40%, 15%, and 24% respectively of all the foods intaken. b. Relatively large amount of protein and fat are intaken. Especially animal protein shows 64% of total protein intaken. c. Intake of vitamin $B_2$ is low but all other nutrients are intaken in relatively good amount. 2. In case of Hwa-Jeon-Min ('fire-field' farmers): a. Staple foods are cereals, potatoes, and vegetables. These foods occupy 61%, 19%, and 14% respectively of all the foods intaken. b. Intaken amount of animal foods is only 7 grams and this figure is only 0.1% of total foods intaken. c. Intake of animal protein is 0.4 to 0.6 grams per day and that of fats is 8 to 10 grams only. d. Intake of carbohydrate is very high. The calorie derived from the carbohydrate is 86% of total calorie intaken. e. Intakes of calcium, vitamin A, Vitamin $B_1$, Vitamin $B_2$, and niacin are low. Especially, calcium, vitamin A, and vitamin $B_2$ are deficient from their food habbits.

The principal objective of this study was to identify the dietary and physical activity patterns of obese preschoolers, and to determine the association between child obesity and mother's' dietary habits or thoughts regarding dieting/weight. This is a cross-sectional, community based study, and 305 preschoolers who attended kindergarten in Seoul and its surrounding area were selected. The measurements of dietary habits both in preschoolers and their mothers, physical activities of preschoolers, and daily servings of foods were based on parents' self report. Weight and height were used to calculate WLI (weight length index) in preschoolers and BMI (body mass index) in their mothers. The subjects were divided into two groups 245 normal weight preschoolers (including underweight 15.1% and normal weight 65.6%) and 59 obese subjects (overweight 14.4% and obese 4.9%). With regard to dietary habits in normal and obese preschoolers, we noted significant differences in 5 questions, such as mostly eating heavy meals, one serving size, eating speed, overeating, and obsession about eating. No differences in daily servings of major foods and snacks, except fruits and potatoes, were noted between normal and obese children. Among 13 questions regarding mothers' dietary habits, only 3 questions-"preferred to instant foods", "finish meals within 15 minutes", "use nutritional information for selecting foods" were significantly different between normal and obese subjects. The total scores of mothers' dietary habits was significantly and negatively correlated with number of mother's dieting experiences or mother's BMI, but was not correlated with preschooler's obesity.

Food choice is influenced by many factors including physical, social, psychological and food technological developments. This research is based on the survey on Puchon housewives dietary culture according to season and special occasions and the current consumption pattern of traditional fermented foods. The objective is to find out the current consumption and to use this data as the principal element needed to explore changes in consumption patterns and to uphold and develop the consumption of traditional fermented food. Questionnaires were collected 282 housewives in Puchon city. Data were analysed with SAS software package for t-test, F-test and Duncan’s multiple range test. Results of relationship between dietary culture of Puchon housewives and consumption patterns of traditional fermented food items; 1. If we look at seasonal foods, Puchon housewives responded that they normally prepare traditional foods for such special occasions as Chusok(89%), New Year(84%) and January full moon Day(77%). For family celebrations, they cook on their in-laws birthdays(91%), their husbands birthday(84%), childrens birthdays(73%) and their own birthday(32%). They also responded that they eat out on their own birthday(41%), on Christmas Day(19%), on childrens birthdays(17%) and on their husbands birthday(11%). 2. If we look at the age of housewives and their dietary culture, more young housewives tend to eat out on their own, their husbands and their childrens birthdays. As for their educational background, less educated housewives tend to prepare flood at home on New Years Day, while more educated housewives would eat out on their own birthdays. As for the type of family, mere housewives in nucleus families eat out on Christmas Days compared to those in extended families. Also, those in extended families tend to make food at home rather than eating out on their own birthdays. In case of the husbands birthday, there was some difference according to family income (p<0.03).

Dyslipidemia, defined as elevated triglyceride (TG), total- and LDL-C, and/or decreased HDL-C levels, is considered a principal risk factor for cardiovascular disease. The low-density lipoprotein receptor (LDLR) family has been considered a key player in the prevention of dyslipidemia. The LDLR family consists of cytoplasmic membrane proteins and plays an important role not only in ligand-receptor binding and uptake, but also in various cell signaling pathways. Emerging reports state that various functional ingredients dynamically modulate the function of the LDLR family. For instance, oats stimulated the LDLR function in vivo, resulting in decreased body weight and improved serum lipid profiles. The stimulation of LRP6 by functional ingredients in vitro activated the Wnt/${\beta}-catenin$ pathway, subsequently suppressing the intracellular TG via inhibition of SREBP1, $PPAR{\gamma}$, and $C/EBP{\alpha}$. Furthermore, the extract of Cistanchetubulosa enhanced the expression of the mRNA of VLDLR, followed by a reduction in the serum cholesterol level. In addition, fermented soy milk diminished TG and total cholesterol levels while increasing HDL-C levels via activation of LRP1. To summarize, modulating the function of the LDLR family by diverse functional ingredients may be a potent therapeutic remedy for the treatment of dyslipidemia and cardiovascular diseases.
