This research aims to find the information concerning nutritional status and food intake in Korean dirt betic men. Thus, the survey was made on 202 NIDDM patients over 35 age at University Hospital. The data were analysed using F-test and mutiple comparison in SAS package program. Main results were as follows : Incidence of diabetes is high in their forties and fifties. Most of them are salary men, administrators, and professionals in middle class, who reside in metropolitan area including Seoul. They used to take light exercise and were founded NIDDM by subjective symptoms. 36.6% of them have other diseases simultaneously such as hypertension, cancer, etc. Food intake pattern prior to incidence was that intake frequency of grains, sugars, protein foods, and liking foods was higher than of processed foods. Amounts of calorie intake were shown to be lower than normal persons, so that it seemed to be controlled by doctors. In addition, the calorie ratio derived from fat was lower than RDA. Thus protein and carbohydrate ratio was relatively higher than RDA. Total moan fatty acid intake was 32.15g and it is no significance among weight groups in various fatty acid intakes. With respect to the physical standards of the diabetic men, weight, PIBW BMI, BMM, 757, arm circumference, and waist /hip ratio were higher than in normal. Therefore it seemed that these factors would be related to the diabetics. From now on, it is required to research the correlations of fatty acid intakes on the diabetes and their influence to serum lipid profiles.

This study investigated elementary school students' perception and recognition of soybean foods and assessed their intake levels of isoflavones. A survey was administered to 300 sixth grade students in Daegu. The amount of isoflavones consumed by students was estimated by food intake frequency and the 24-hour recall method based on their general dietary habits and perception of soybean foods. Subjects' mean height was 152.2 cm, mean weight was 45.2 kg, and body mass index was $19.4kg/m^2$. All subjects had knowledge of soybeans and most preferred bean-paste pot stew of all soybean-based foods. Students typically ingested isoflavones two or three times per week in the forms of tofu, bean-paste pot stew, and bean sprouts. The average amount of isoflavones consumed from soy foods was 26.43 mg/day (daidzein 9.27 mg/day and genistein 17.16 mg/day) as assessed by food frequency questionnaire and 30.83 mg/day (daidzein 13.63 mg/day and genistein 16.40 mg/day) by the 24-hour recall method, showing that the 24-hour recall method assessment amount was 4.4 mg higher than that of the food frequency questionnaire. The major food sources of isoflavones were soybean paste and soybeans. Those who were especially knowledgeable about soybean foods expressed the view that these sources were a good or affordable enriched source of isoflavones.

The purpose of this study was to obtain baseline data on dietary management of women's constipation. We estimated the prevalence of self reported constipation, bowel habits and foods & nutrients intake. The subjects were 169 female college students (normal = 92, constipation group = 77) aged 19 to 23 years. We conducted anthropometric measurements, an evacuation habits survey, and a dietary intake assessment for three days by a 24 hour recall method. The prevalence of self reported constipation was 46% (n = 77). Results showed that bowel habits (the difficulty of evacuation, the duration of evacuation and the feeling after evacuation) were significantly different between the two groups. Over 65% of constipation group used laxatives for constipation relief. Frequency of stress and deep sleeping were related with constipation. In daily food consumption and nutrients intake, there was not a significant difference between the groups. However in relation to bowel habits which factors influence constipation, the study showed that the intake of water, potatoes, kimchi, and fruits correlated with evacuation facility. Further, there were no findings in the difference of foods consumption and nutrients intake between the two groups. But some life style changes and food intakes (potato and kimchi) may be useful to improve constipation symptoms in young women.

This study was performed to evaluate the congeners of polychlorinated dibenzo-p-dioxins(PCDDS) and polychlorinated dibenzofurans(PCDFs) in Korean foods among children in Korea, in comparison with the findings in their mothers. The PCDDs and PCDFs intakes of 24-h diet duplicates were estimated from the previous Korean reports. In Korean children and their mothers of this study, major sources of lipid intake were plant-based foods(62% for children, 66% for their mothers). The women took 34% of lipid from animal sources, among which meats were leading sources of animal lipids(30%). Fish and shellfish were accounted for 4% in total lipid intake. Daily intake of PCDDs and PCDFs in the children md their mothers were 0.002-3.188 and 0.002-2.717 pg WHO-TEQ/day in animal sources and ND-0.283 and ND-0.296 pg WHO-TEQ/day in plant sources, respectively. PCDDs/PCDFs intake from animal origin was the major exposure source for both children and their mothers in Korea. Among the 17 PCDD/Fs congeners, 2,3,4,7,8-pentachlorodibenzofuran was assumed to be the effective exposure marker for diet intake.

Objectives: In this study, we suggest a Korean NOVA food classification that can be applied to food consumption among Korean. Based on this suggestion, the nutritional intake of Korean adults from ultra-processed foods (UPFs) was estimated. Methods: Korean commercial food was categorized based on the NOVA food classification criteria through the Korea Food Code and expert meetings. Then, the nutrient intake status of 6,991 participants in the 2018 National Health and Nutrition Examination Survey was analyzed according to the food processing level. Then, 4,152 adult participants (age 19-65) were divided into quartiles on the basis of their intake of UPFs, and the nutrient intakes from UPFs were compared. Results: Korean NOVA Food Classification defines with priority Group I (Unprocessed/ Minimally processed foods) and Group II (Processed culinary ingredients) foods based on the food cooking or consumption. Then, Group III (Processed foods) and Group IV (UPFs) are classified according to whether the characteristics of the raw materials used are maintained or whether the food was consumed before the 1970s. Our analysis results showed that most of the calories in the diet were consumed by Group I (52.7%), followed by Group IV (29.3%). After categorization of the adult participants into four groups according to their energy consumption from UPFs, we found that the highest consumption group (Q4) was younger and had higher percentage of men than women. The comparative analysis of the consumption of ultra-processed foods by Korean adults revealed that participants of a younger age and men consumed higher energy from UPFs than older participants and women, respectively (P < 0.01). Furthermore, the larger intake of UPFs was associated with an increasing trend for a higher intake of energy, sugar, saturated fat (P for trend < 0.001), total fat (P for trend = 0.021), and sodium (P for trend = 0.005), whereas the intake of carbohydrate, protein, and dietary fiber had a decreasing trend (P for trend < 0.001). Conclusions: With the current increase in the consumption of processed and ultra-processed foods, it is important to carefully consider not only nutrient intake but also the level of food processing.

Purpose: Although excessive intake sugar may increase the overall energy intake, it leads to a reduction in the intake of foods containing other nutritionally adequate calories. Excessive sugar intake can also lead to an unhealthy diet, weight gain, and risk of metabolic disorders. The purpose of this study was to assess the recognition by college students, their frequency of eating sugar containing foods, and suggesting sugar reduction in the menus of institutional foodservices. Methods: A questionnaire was used to survey 145 college students to evaluate their recognition and eating frequency of consuming sugar containing foods. Subsequently, sugar reduction menus for institutional foodservice were suggested. Results: Most of the subjects (80.0%) were aware of the meaning of sugar reduction. The necessity of reducing sugar in their meals was recognized by 57.8%. These participants tended to check nutrition labeling more. Eating frequencies of sugar containing foods were not significantly different by the subjects' BMI, but they were significantly different by gender, when evaluating cooked foods. We suggested 20% sugar reduction recipes of Korean style barbequed pork, and sweet and sour chicken for institutional foodservices. Conclusion: The awareness of college students and the knowledge regarding sugar reduction were low. Sensory acceptabilities of Korean style barbequed pork and sweet and sour chicken were not significantly different, until the benefit of 20% sugar reduction was mentioned. Thus, continuous education for reduction of sugar intake are required, and also efforts are needed to develop menus containing less sugar.

The purpose of this study was to provide the basic information for developing sugar related nutrition education programs for children in child-care facilities and their parents. The results showed that the total score of parent's dietary attitudes towards sugar-rich foods was 17.94 and the total score of parent's nutritional knowledge was 3.67. A positive relationship was observed among items of parent's dietary attitudes (p<0.01), and some correlations were also observed between the total score of parent's nutritional knowledge and the total score of parent's dietary attitudes (p<0.05 or p<0.01). The total average score of children's eating behaviors for sugar-rich foods was 23.98, and the item with the highest score was 'I often eat candy, chocolate and jelly'. For children, food that received the highest preference was chocolate, and soft drinks received the lowest preference. The most frequently consumed food item was candy or caramel, and the least frequently consumed food item was soft drinks. There were positive correlation among the total score of children's eating behaviors, food preferences, and food intake frequency (p<0.01). When parent's tried to reduce the sugar intake, children's total score of eating behaviors (p<0.001) and food intake frequency (p<0.001) for sugar-rich food was lower. We conclude that parent's dietary attitudes may influence children's eating behaviors, food preferences, and food intake frequency for sugar-rich foods.

BACKGROUND/OBJECTIVES: Turmeric and its active component curcumin have received considerable attention due to their many recognized biological activities. Turmeric has been commonly used in food preparation and herbal remedies in South Asia, leading to a high consumption rate of curcumin in this region. However, the amount of curcumin in the Korean diet has not yet been estimated, where turmeric is not a common ingredient. SUBJECTS/METHODS: This study utilized the combined data sets obtained from the Korea National Health and Nutrition Examination Survey conducted from 2008 to 2012 in order to estimate the curcumin intake in the Korean diet. The mean intake of curcumin was estimated from the amount of curcumin-containing foods (curry powder and ready-made curry) consumed using reported curcumin content in commercial turmeric and curry powders. RESULTS: Only 0.06% of Koreans responded that they consumed foods containing curcumin in a given day, and 40% of them were younger than 20 years of age. Curcumin-containing foods were largely prepared at home (72.9%) and a significant proportion (20.4%, nearly twice that of all other foods) was consumed as school and workplace meals. The estimated mean turmeric intake was about 0.47 g/day corresponding to 2.7-14.8 mg curcumin, while the average curry powder consumption was about 16.4 g, which gave rise to curcumin intake in the range of 8.2-95.0 mg among individuals who consumed curcumin. The difference in estimated curcumin intake by using the curcumin content in curry powder and turmeric may reflect that curry powder manufactured in Korea might contain higher amounts of other ingredients such as flour, and an estimation based on the curcumin content in the turmeric might be more acceptable. CONCLUSIONS: Thus, the amount of curcumin that can be obtained from the Korean diet in a day is 2.7-14.8 mg, corresponding to nearly one fourth of the daily curcumin intake in South Asia, although curcumin is rarely consumed in Korea.

Younghung-myun is located on a small island under the jurisdiction of Gyunggi province. The island occupying a total of approximately 40sq km is populated by 5,850 people. Two areas within the island were selected for this survey; 1) Nae 4-ri in Younghung-myun (mainly engaged in farming) 2) Nae 5-ri in Younghung-myun (mainly engaged in fishery) The survey was conducted for the period of 5-12 august 1978. Intake of foods and nutrients of all members in the households surveyed by means of questionnaire was computed based on number of meals a day. On the other hand, daily intake of nutrients by an individual was calculated by sex, age and type of work based on the conversion rate of RDA (Korean Recommended Dietary Allowances for Adult). The results obtained are summarized; 1. Status of food intake Average daily food intake of an individual in the surveyed areas was 1,018gm. Out of 1,018gm above, 490gm which represent 48% of the total intake were from cereals, grains or other vegetative products. Ratio of animal-origin foods was determined as only 16% of the total intake. These findings led us to the conclusion that people in the surveyed areas live heavily on vegetative foods. 2. Status of nutrients intake 1) Overall average intake of calorie by an individual in the surveyed areas was 2026.3Kcal per day. On the other hand, average calorie intake by adult persons was 2,491.3 Kcal per day, which is lower than 2,700 Kcal recommended by RDA by approximately 7.7%. Furthermore, it was observed that most of 2,491.3 Kcal obtained by adult persons was from such vegetative foods as cereals, grains, ect. 2) Overall average intake of protein by an individual in the areas surveyed was 52.2gm per dar. On the other hand, average protein intake among adult persons was 67.7gm a day, which indicates lower intake of protein than 80gm of RDA. It was also found that 84.3% of the protein intake by an adult person was of plant origin. 3) Overall average of fat intake by an individual in the areas surveyed was 18.9gm per day, whereas average fat intake among adult persons was 23. 2gm a day. It was brought to our attention that the average fat intake by adult persons is much lower than 36gm recom mended by RDA. 4) Average calcium intake among adult persons in the areas surveyed was 457.1mg per day, that is somewhat lower than 500mg in RDA. However, average iron intake among adult persons in the areas was slightly higher with 10.5mg a day than 10mg of RDA. 5) With exception with vitamin C, intake of all other vitamin groups, such as vit. A, vit. $B_1$, vit. $B_2$ and niacin, were lower among the inhabitants than recommended by RDA. 3. Economic status Average schooling years of food handlers was 6.5 years with average monthly income of \89,000 in the areas surveyed. Petroleum was used by majority of the households for fuel.
