The purpose of this study was to develop the dietary enhancement program for rural elderly. The subjects consisted of 71 normal healthy elderly aged over 60 living in rural and senior citizen center. Daily supplementation of 20g soybean powder of 3 months revealed no statistically significant elevation in serum parameters of the elderly, but resulted in the increment in the number of the subject with normal range of serum parameters and the improvement in perceptions of health status by CMI score, even though the nutrients intake had constantly lowered. The nutrients intake of rural elderly was very low: energy intake was 59-68% of RDA, that of protein 47~59%, and clacium 21~60% only. Supplementation of 20 g soybean powder per day for 3 months, did not enhance nutrients intake of rural elderly. We can recommended that constant nutrients supplementation program as well as dietary enhancement program are needed to improve the quality of life of rural elderly.

In this study, we investigated the effects of sweeteners on the quality of Kakdugi through the addition of 1.8% sugar, 0.006% sodium saccharin or 0.006% stevioside using a physicochemical test and sensory evaluation during fermentation at $20^{\circ}C$. The addition of sugar to Kakdugi resulted in the lowest pH and the highest total acidity relative to the control and experimental groups during the fermentation period. The number of lactic acid microorganism gradually increased and then decreased. The sensory evaluation revealed that the addition of sodium saccharin to Kakdugi resulted in the highest sweet smell and taste followed by the addition of stevioside. The addition of sodium saccharin to Kakdugi showed the highest sweet taste and the best texture, and the sweetness compensated for the sour smell and taste.

This nutritional survey was conducted from September 17 to October 6, 1984, in order to investigate the state of the nutritional intakes of perple living Gapoe-Dong, coastal area of Korea. This survey covered a total of forty houses. The method of this research was based on the interiview-survey with questinaires. All of the food taken daily by the people are all weighed before cooking ; the rest of food after mealing are also weighed. Thus the amount of food taken by people can be come out. The results were summarized as follows; 1) The average intake of all nutrients were below the RDA, especially calorie, vitamin B2, calcium and iron were insufficient. The protein intake was only 55.2g but the contribution of animal protein to total protein was adequate(38%). It was provided mostly by fish and shell-fish. 2) Chief food sources were rice, vegetables, fish and shell-fish, and milk, eggs, oil, potato, and fruits were insufficient. 3) The level of education and the number of family were significantly correlated to the nutrientintake, especially correlation between family-size and colorie, calcium intake were significant.

The incidence of total molds, Fusarium species, and the estrogenic mycotoxin,zearalenone, in Korean grain samples were investigated . The majority of molds infecting grain were identified as belonging to the genus Alternaria , with an average infection rate of kernels of 43% and 32% in rice and baley, respectively. Fusarium speciens were less common, with average infection rates of 13% and 19% in reice and barley, respectively. A number of field fungi including Curvularia and Dactylaria were also observed. Among the Fusarium speices, 71 of 94 Fusarium isolates were identified as F.semitectum. A few F. moniliforme and F. equiseti were observed linked immunosorbent assay (ELISA) or high-performance liquid chromatography(HPLC). In addition, deoxynivalenol was not deteted by ELISA . However, thepresence of molds, including Fusarium species, may pose possbile health hazards to persons consuming those grains.

Tofu has been playing an important role in people's daily diet in most of Asia and recently in North America due to several health-promoting functions, preventing and treating a number of chronic diseases such as cancer, coronary heart disease and osteoporosis. The objective of this study was to investigate the effect of different levels of yakong incorporation (0, 5, 10, and 15%, w/w) in preparation of firm tofu. Quality parameters such as pH, titratable, moisture content, color, and consumer preference were determined, and their correlations were analysed. There were no significant differences in pH, titratable acidity, and moisture content due to different levels of yakong incorporation studied (p>0.05). A significant decrease in L$^{*}$ and b$^{*}$-values whereas significant increase in a$^{*}$-value was observed (p<0.05). Five percent yakong tofu received the most favorable mean scores with respect to color, texture, and overall acceptability. Correlation analysis revealed that yakong incorporation was well correlated with some of physicochemical properties as well as consumer preference.

The relationship between mortality and the Korean Healthy Eating Index ("KHEI") is well established. This study was to investigate the associations between health habits, mental health, and nutritional status and KHEI in older Koreans (aged≥65 years). A total of 4,247 subjects (1,842 men and 2,405 women) that participated in the 2016~2018 Korean National Health and Nutrition Examination Survey were included in the analysis. The lowest scoring KHEI item was milk and milk products. KHEI tertile groups were classified by total KHEI score. Tertile group percentages were related to general characteristics such as gender, residential area, educational level, income level, number of family members, and age. Logistic regression analysis adjusted for general characteristics, showed that ex-smokers (OR: male 1.53 female 2.29), smokers (OR: male 2.90), low hand grip strength (OR: male 1.42 female 1.90), poor self-rated health status (OR: female 1.83), stressful mental status (OR: female 1.51), poor health-related quality of life (OR: female 1.64), poor nutritional status (OR: male 2.88~37.20 female 1.98~16.12), and food insecurity (OR: male 6.87 female 2.03) were significantly related to a lower KHEI. This study suggests that gender-specific associations exist between mental health status and KHEI.

A study was performed to develop as a screening tool, the Simple Evaluation Questionnaire for screening Overweight Dietary Patterns in people in their 20's. We used the data from the 20 to 29 year old subjects who participated in the three surveys: the health behavior survey, the dietary habit survey and the food intake survey - as part of the National Health and Nutrition Survey of 1998. The 1,493 adults were classified into two body fatness groups, that of normal (including the underweight) , and the overweight (including the obese) on the basis of their relative body weight (RBW). When comparing general variables between the two groups, significant differences (11 variables) were found in gender, sadness/depression state, stress level, age, number of diseases, age when overweightedness started, maximum body weight, sleep length, presently a smoker, everyday smoking habits, number of alcoholic drinks in the past month, and the number of alcoholic drinks when dunk, as well as snacking frequency and fatty food consumption. There were significant differences between the two groups in the three variables of daily soup/kuk, pan fried fish/meat/poultry and cooked fish paste/ham/dried squid in terms of cooked food intake, and 11 variables of food size, cooked rice, stews, vegetables and kimchi at breakfast, panfried foods and beverage/teas at lunch, cooked rice and stews (liquid) at dinner, cooked fish paste/ham/dried squid at snacks and cooked fishpaste/ham/dried squid at snack between lunch and dinner. In terms of raw food intake, we observed significant differences (8 variables) in daily food intake and grains, grains/vegetables/fishes (shellfish) at breakfast, meat at lunch and milt at snack after dinner. After developing questions with indicators and analyzing the indicators by logistic regression analysis using 34 variables, including these 33, plus eating-out frequency, we chose 10 questions for the simple evaluation of dietary patterns for the overweight category, in order to give each one point each. Among them we assigned an additional point to one question and two points to another question. The average scores of the overweight and normal groups, as shown by the questionnaire developed, were 5.97 $\pm$ 2.36 and 7.36 $\pm$ 2.21, respectively. A score of seven points was selected as the cut-off point. We examined the sensitivity, specificity and positive predictive value of the questionnaire to the results of 49.3%,75.4% and 68.8%, respectively. The total score categorized as an overweight dietary pattern was 30.2%.

Contributions of specific foods to absolute intake and between-person variance in 13 nutrients were examined to develop a short food frequency questionnaire (FFQ) for the Korean elderly using dietary data collected by a semiquantitative FFQ with 96 food items. The contributions of specific foods to 90% absolute nutrient intake were measured by assessing their percentage to the total consumption of a nutrient by our samples(n=98). To assess the contribution of the foods to the between-person variance in intake of each specific nutrient, stepwise multiple regression was performed. Cumulative R2 served as the measure of contribution to variation in intake. The most important food source of absolute intake was rice for energy and protein. Important foods of between person variance contribution include bread for energy and pork for protein. Important foods of absolute and variance contribution of nutrient intake were similar for fat(noodles including jajangmyun and kalguksu), calcium(anchovy and milk) and vitamin A (carrot). The number of foods necessary to account for the variation in nutrient intake among older people in Korea differ considerably by nutrient: 18 - 43 and 8-26 foods were accounted for the respective 90 and 80% of absolute intake depending on nutrients. Carbohydrates and vitamin A and C had relatively a few major sources, thus may be assessed well by a small number of foods. Conversely, iron, potassium and B vitamins appear to need longer lists of foods. Fewer numbeer (6 - 12 and 4 - 9) of foods were required for the corresponding percentages of between-person variation for all nutrients. Depending on nutrients, 0.980-0.995 and 0.924-0.987 were respective correlation coefficients of nutrient intakes measured by 96 food items with those by lists of foods for 90% and 80% of absolute intake contribution. These findings suggest that an incomplete food list on the basis of its contribution to absolute and between person variation intakes may still be effective in discriminating among individuals. The results of this study may be useful in the design and use of dietary questionnaire.
