국내에서 사용되고 있는 주요 유기인계농약 11종에 대한 한국인의 식이섭취량을 농산물중 잔류량과 식품계수로 부터 산정한 결과 1인당 1일 $31\;{\mu}g$ 으로 나타났다. 식품군별 섭취량 비율은 곡류 56%, 채소 23%, 과일 14%, 두류 기타 7%이었다. ADI 값에 대한 식이섭취량 비율을 보면 diazinon 6.1%, fenthion 5.8%, fenitrothion 3.3%, EPN 1.5%로 나타났고 11종 농약의 성분별 평균은 1.7%에 불과하였으나 모든 성분에 대한 합계치는 18.7%에 이르렀다. 따라서 현재와 같은 유기인계의 농약의 사용실태 하에서는 농산물중의 농약잔류가 한국인의 국민건강에 손상을 줄 수 있는 수준은 아니지만 체계적인 섭취량 평가에 착수해야 될 것으로 판단되었다.

The study surveyed the dietary behavior, food intake, and food preference for breakfast of elementary, middle, or high school students, a total of 354 boys and 305 girls. The students skipped breakfast due to no appetite, followed by no time. Elementary school students ate grains and potatoes more often than middle or high school students(p<0.05), and bap was the most frequently consumed cereals, with juk and tteok as the least. High school students ate meat, ham, sausage and boiled fish cake (eomuk) more often than the elementary or middle school students(p<0.05). Middle school students ate milk and dairy products as well as vegetables and fruits more often(p<0.05) than other foods. Preference for fish and fresh vegetables and salad was significantly high in middle school students. The score of dietary behavior was the highest in elementary school students, followed by middle and high school students(p<0.001). As the students advanced to the upper grade schools, breakfast skipping increased, with lowered dietary behavior scores. The results suggest that a variety of breakfast menus and recipes should be developed at home and schools by considering the preference of students in order to reduce breakfast skipping and to improve their satisfaction with breakfast.

The object of this study was done to assert the dietary habits, food intake, and dietary attitudes of 332 middle school students in a small city. The subject were divided into doe groups based on weight length index (WLI). Anthropometric data showed that the mean height and weight were 169.5 $\pm 8.2 cm and 55.1 $\pm 11.5 kg in the male students and 158.9 $\pm 5.9 cm and 48.1 $\pm 7.6 kg in the female students. The mean WLIs for male and female students were 103.0 $\pm 19.7 and 96.3 $\pm 12.8, respectively. Of the male students 27.9% and of the female students 32.1% were underweight, and of the male students 28.9% and of the female students 13.0% were overweight based on WLI index. Lack of good dietary habits in the overweight group tended to be the highest, the normal group was the second highest, and the underweight group was the lowest. The regularity of eating breakfast and flood prejudice scores in the overweight group were significantly higher than those in the normal and underweight group. With respect to flood intake, the normal group tended to consume grains, yellow or green vegetables, vegetables with light color, fruits, milk, yogurt, cheese, seaweeds, fat-floods, instant floods, sweet floods, carbonated drinks, and spicy and salty floods more frequently. The underweight group tended to consume meat-ham, eggs, fish and fried, stir-fried flood more frequently In dietary attitudes, the overweight group tended to have more favorable dietary attitudes, and the normal group tended to have negative dietary attitudes. The underweight group showed more negative responses to trying to eat/drink milk, yogurt, or cheese everyday than the overweight groups. It might be suggested that more effective nutritional programs should be developed and implemented to ensure good dietary habits in middle school students, including the overweight, as well as the underweight group. Further research on the comparison of dietary characteristics is needed, with consideration of the subjects WLI.

The purpose of this study was to examine the characteristics of the dietary intake of Korean elderly according to chew-ing ability using data from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted during 2007-2010. Among subjects aged 65 years and over, more than half, 54.3% of elderly people, were classified as the difficulty in chewing group (DC). The DC group had lower nutrients and food intakes than those of in the no difficulty in chewing group (NDC). Findings showed that subjects in the DC group consumed fewer foods, especially fruits and vegetables. In addition, the DC group had significantly lower intakes of pan-fried food, stir-fried food, braised food, and seasoned-cooked vegetables, which could not be easily cooked or chewed. On the other hand, the number of soups and stews included in the top 30 largely consumed dishes were higher in the DC group than in the NDC group. No difference in numbers of daily meal/snack intake was observed between the two groups, however, the DC group had lower numbers of side-dishes compared to the NDC group. Fewer side-dishes per meal could be related to lower intakes of nutrients in dietary quality. Findings of this study demonstrated that dietary intake was influenced by chewing ability of elderly Korean people. Therefore, study of factors affecting dietary intake such as convenient cooking methods to decrease cooking time and skills to extend preservation and storage time of foods will necessary. In addition, development of food products and new techniques of cooking considering health status, chewing, and swallowing ability is required for the elderly, followed by establishment of standards for senior-friendly food products.

The purpose of this study was to investigate the eating patterns, nutrient intakes, blood levels, and health status of male college students in Seoul according to body mass index (BMI). In this study, we classified subjects into normal weight (n=240), under weight (n=11), and obese (n=46) groups according to BMI. The weight and BMI were significantly higher in the obese group compared to other groups (p<0.0001). The obesity was associated with overeating and frequent eating. The under weight group showed significantly higher consumption of fast food, snacks, and fried foods compared to the other groups (p<0.05). The intakes of milk, meat, fish, eggs, and fried food and preference ratios were higher in the obese group (p<0.05). The male college students in this study showed insufficient intakes of calories, vitamin C, folic acid, and calcium. The plasma LDL-cholesterol levels in the obese group were higher compared to the other groups. In conclusion, intake of nutrients among male college students is found to be insufficient and requires nutritional education. The under weight group showed regular eating habits and increased nutrient intake. The obese group was shown to need more exercise with higher intakes of vegetables and fruits.

BACKGROUND/OBJECTIVES: Food literacy (FL) is a crucial skill for selecting sustainable and healthy food options, necessitating the identification of vulnerable groups in the community using valid measurement tools. Identifying weak domains in FL is essential for enhancing the overall FL. This study examined the FL levels of Seoul citizens based on their sociodemographic characteristics and assessed the relationship between FL, food intake, and weight status. SUBJECTS/METHODS: This study utilized the data from the Seoul Food Survey, a cross-sectional study employing representative samples of Seoul citizens. Data collection occurred from September to October 2021, with 4,039 citizens aged 18 yrs and above participating in face-to-face surveys. Thirty-three FL items were assessed, comprising 14 items in the nutrition and safety (NS) domain, eight items in the cultural and relational (CR) domain, and 11 items in the socio-ecological (SE) domain. In addition, data on food intake sufficiency and obesity status were collected. The descriptive statistics, t-tests, analysis of variance, and logistic regression analysis were used for analysis. RESULTS: Men, students, young adults, older citizens, and people experiencing food insecurity had the lowest scores for all the FL domains. The highest quartile group of NS scores had a higher probability of consuming adequate servings of vegetables and fruits, with significant linear trends observed (P for trend < 0.05). In all three FL domains, the odds ratio for obesity was significantly lower in the groups with high FL scores (P < 0.05). CONCLUSIONS: A close relationship was observed between low FL, obesity, and food intake, even after controlling for other covariates. Vulnerable groups with low FL were also identified. Therefore, it is essential to develop programs to improve FL and the health and well-being of these groups.
