This study investigated the status of mixed grain diet by 68 people with diabetes living in Jeollabuk-do and performed sensory evaluation of different composition of mixed grains to improve the sensory characteristics based on the investigation. BMI of all subjects were measured and found that 61.7% were overweight. 94.1% of them ate mixed grains and females ate more mixed grains than males (p<0.05). Most males and females answered that they ate mixed grains for their health. Females added more mixed grains than males (p<0.01). More females (47.1%) than males said they would continue to eat mixed grains (p<0.05). 59% of them said they had eaten mixed grains for more than 3 years. 46.0% of them said they purchased mixed grains at a small mart near their houses. The mostly added grain to rice was black soybean (76.5%). RMGD-50 is composed of six mixed grains excluding nonglutinous rice and has the mixing rate of 50%. RMGD-40 has the mixing rate of 40%. Sensory evaluation was performed and RMGD-50 got lower score ($3.33{\pm}0.68$, $3.50{\pm}0.81$) than RMGD-40 in the appearances and color. RMGD-40 with Control 1 that includes more glutinous grains and Control 2 that is polished rice were compared. RMGD-40 got lower score than Control 1 in its appearances, smell and color, although there wasn't a meaningful difference. For the people with diabetes who are accustomed to mixed grains, the polished rice got the lowest score in moisture amount, gumminess and overall taste ($3.26{\pm}0.82$, $3.48{\pm}0.85$, $3.19{\pm}0.70$). It showed meaningful difference from RMGD-40 and Control 1 (p<0.01). Consequently people with diabetes preferred mixed grains that include more glutinous grains that have lower mixed ratio. So it is necessary to educate the people with diabetes about eating grains for better blood sugar management. Continual study and development of mixed grains that can help people with diabetes to control their blood sugar are necessary.

Purpose: This study was conducted to examine the relationship among cognitive function, nutrition screening initiative (NSI) score, and food intake status. Methods: A total of 409 subjects aged over 60 years were recruited from the Yongin dementia prevention and control center. Mini Mental State Examination Dementia Screening (MMSE-DS) method was used to assess the cognitive function of the subjects. Information on health related behaviors and food intake was collected by face to face interview using a structured questionnaire. The questionnaires included the NSI DETERMINE checklist, food intake sheets by 24 hr recall method and by semi-quantified food frequency questionnaire. Results: Subjects were divided into low cognitive or normal groups according to the MMSE-DS result. The prevalence of low cognitive function in the subjects was 25.7%. The low cognitive group exercised less and had higher nutritional health risk than the normal group. The low cognitive group had lower consumption of polyunsaturated fatty acid and higher tendency of thiamin, riboflavin, and iron deficiency. The low cognitive group had less frequency of eating mackerel, pepper, tangerine, and watermelon and higher frequency of eating white rice and cookies than the normal group. Conclusion: The results of this study imply that the cognitive function of elderly is related to exercise behavior, nutritional health risk, and food and nutrient intake status.

This study was carried out to compare the differences in dietary habits, food consumption patterns, nutrient intakes, and serum lipid levels according to kimchi consumption in college students. The anthropometric and biochemical parameters of blood samples from the subjects were investigated, as well as a kimchi frequency questionnaire, 24-hour food recall and dietary habits. The subjects were divided into two groups according to their kimchi consumption level based on the quantitative kimchi frequency questionnaire-kimchi consumption under 50 g group and kimchi consumption over 50 g group. As kimchi consumption increased, consumption of white rice (p<0.05) and noodles increased, whereas the consumption of confections decreased. The kimchi consumption over 50 g group was more likely to eat balance meals (p<0.05), and consume fruits and vegetables (p<0.05) than the other group. On the other hand, the kimchi consumption under 50 g group was more likely to consume milk than the kimchi consumption over 50 g group. The energy and sodium (p<0.05) intakes in the kimchi consumption over 50 g group were higher compared to the kimchi consumption under 50 g group. Kimchi consumption was positively correlated with HDL-cholesterol and negatively correlated with body fat, BMI, and blood glucose level. In addition, kimchi consumption was positively correlated with cereals, meats, and vegetables intakes, and negatively correlated with milk and dairy product intakes. However, there was no significant difference between the two groups.

This study was conducted to investigate whether the parental sodium intake and the sodium intake of adolescents are consistent with each other, to identify factors affecting sodium intake of adolescent children, and to measure sodium intake at home. For this study, 405 subjects in the National Health and Nutrition Survey of 2015 whose sodium intake was measured among nutritional intake were selected, excluding elementary school students, middle school students and high school students aged 7 to 18 years. The data were then matched with the father ID and the mother ID in the youth ID. The results of this study were as follows: ${\beta}=-0.187$ for male adolescents, ${\beta}=0.192$ for older adolescents, ${\beta}=0.153$ for higher adolescents, and sodium intake for adolescents. This is because the mother usually prepares meals in Korea. On the other hand, it is predicted that parents will not be able to consider the quality of their children due to the increased number of dual-income couples.

Purpose: This study was conducted to investigate dietary habits related to weight reduction and snack intake habits of $4^{th}$ to $5^{th}$ grade elementary students located in Jeju-si, Jeju, South Korea. Methods: The $4^{th}$ and $5^{th}$ grade elementary school students (total n = 234, equally matched numbers of normal weight children and overweight/obese children (n = 117/group)) were surveyed using a questionnaire and a 24-hour dietary recall method in Oct 2015. Results: The percentage of students who experienced reduced food intake to control weight was 26.3% in the normal weight group (NG) and 77.6% in the obese group (OG). Most frequently answered meal for reduced intake was snacks in the NG and dinner in the OG. Percentages of daily calorie intake among subjects were 17.2% for breakfast, 33.8% for lunch, 29.7% for dinner, and 19.3% for snacks. Frequency of snack intake was 2.1 times a week in NG and 1.6 times a week in OG, which showed a statistical difference between body weight groups. Types of snack foods were distinctly different depending on where children consumed them, although no difference was observed between NG and OG. In addition, snack intake level of low energy and nutrient-dense foods was significantly lower in the OG compared to the NG, whereas snack intake level of energy dense and low-nutritive foods was not different between the OG and NG. Conclusion: Taken together, snack intake level with consideration of frequency and amount of snack intake showed that children in the OG consumed significantly less low energy and nutrient-dense foods compared to the NG. Therefore, nutritional education for choosing healthy snack foods for children regardless of body weight status is crucial based on family-school links.

Purpose: The aim of this study was to investigate the feeding patterns, use of dietary supplements, and nutrient intake of Korean toddlers. Methods: We used data for 930 toddlers who participated in the 4th Korean National Health and Nutrition Examination Survey (KNHANES) from 2007 to 2009. Feeding patterns and use of dietary supplements were assessed using standardized questionnaires, and nutrition intake was assessed using the 24 hr recall method. Results: In 2007~2009, 48.7% of toddlers used dietary supplements. Most parents (95.4%) initiated a regime of dietary supplements for their children following the advice of friends or relatives. Only 0.4% of parents followed the advice given by their doctors for dietary supplements use. In the survey of nutrient intake for toddlers, the prevalence of inadequate calcium intake was 53.9% for subjects aged 1 year, 55.2% for 2 years and 65.6% for subjects aged 3 years. The prevalence of inadequate iron intake was 52.0% for subjects aged 1 year, 48.7% for 2 years and 48.4% for subjects aged 3 years. In the survey performed on feeding patterns of toddlers during the infant period, mixed feeding accounted for 57.4%, breast feeding for 32.2%,and formula feeding for 10.4%. Sixty-five percent of toddlers began weaning between 4 and 6 months. Conclusions: This study indicated that a number of toddlers were at risk of inadequate calcium and iron intake. The role of professionals in counseling for qualified dietary intake and dietary supplement use is therefore necessary for Korean toddlers.

Water accounts for the largest proportion of body weight and is an essential element for the physiological functioning of the human body. According to 2013-2017 Korea National Health and Nutrition Examination Survey (KNHANES) data, the average water intake of Koreans was 2,167.3 mL/day and 62% of them did not meet the Dietary Reference Intakes for Koreans (KDRIs) for water. However, the consumption of beverages is continuously increasing. KDRIs sets the adequate intake (AI) for water, but tolerable upper intake level (UL) and chronic disease risk reduction intake (CDRR) are not provided. Compared to 2015, the AI of total water from both food and fluids in the 2020 KDRIs slightly increased or decreased according to age. The AI for children 1-2 years old, boys 6-8 years and 9-11 years old, and girls 6-8 years old decreased by 100 mL/day, while that of boys 12-14 years old increased by 100 mL/day. The AI of total water was the sum of the water intake from food and fluids reported by the KNHANES, with an extra milk intake of 200 mL/day. Therefore, it is not appropriate to use the AI of total water intakes for the reference of beverage intakes. It is preferable to consume water or milk rather than beverages containing sugar and others including caffeine, sodium, etc. when drinking fluid water. We suggest the following improvements in the future KDRIs for water: improving the adequacy of the water content ratio of Korean conventional foods, supplementing the fluid water intake survey, reflecting the current water intake status by life cycle, setting KDRIs for water for the elderly considering the physiological changes, health status and dietary habits, and promotion of research on the relationship between water intake and health for Koreans.

The purposes of this study were to investigate consumption of home-delivered meals among children from low-income families and to assess their perception of the home-delivered meal service. A survey was conducted on 392 children who had received home-delivered meals, and 208 questionnaires (response rate: 53.1%) were analyzed using SPSS (ver 18.0). The respondents consisted of elementary school students (36.1%), middle school students (33.7%), and high school students (30.2%). Approximately half of children received home-delivered meals during their semester and vacation periods, and 52.2% of respondents shared the delivered meals with their brothers or sisters. Eighty-six point one percent of respondents consumed delivered meals within 4 hours after the meals were received at home, and approximately a fifth of respondents left the delivered meal boxes on a sink counter or table until eating. Leftover foods were kept in the refrigerator (52.2%) or on the sink counter/table (2.5%). The quality of the home-delivered meal service was assessed as 3.3 points based on a 5-point scale. 'Food safety is good' received the highest score (3.62) and 'Food taste is good' received the lowest score (3.07). The results showed that children receiving the home-delivered meal service should be provided information on proper handling and consumption of the delivered meals at home.

The purpose of this study was to investigate the regional differences in anthropometric measurement, dietary behavior and nutrient intake among the nation-wide college students participating in a nutritional education program via internet. The subjects were 1614 college students (male: 752, female: 862) and divided into 4 regional groups. A cross-sectional survey was conducted using a self administered questionnaire, and the data were collected via internet or by mail. The nutrient intake data collected from food record were analyzed by the Computer Aided Nutritional Analysis Program. Data were analyzed by SPSS 10.0 program. Average age of male and female college students were 23.6 years and 21.0 years, respectively. Most of the male and female college students had poor eating habits, such as unbalanced meals and skipping meals. In particular, more than 60% of the male college students in Chungcheong and Gyeongsang areas had irregularity of meal time. Female students in Seoul and Incheon areas showed significantly higher consumption frequency of yellow and green leafy vegetables compared to Chungcheong and Gyeongsang areas. Female students in Seoul, Incheon and Chungcheong areas showed significantly higher consumption frequency of milk and milk products compared to Gyeongsang area. Calorie, vitamin A, calcium and iron intakes of the male students and calorie, vitamin A, vitamin $B_2$, niacin and calcium intakes of female students were lower than the Korean RDA. Female students in Incheon area showed significantly higher vitamin C and iron intakes compared to the other areas. These results provide a nation-wide information on dietary behavior and nutrient intake among Korean college students.
