This study examined the relationship between dietary supplements and nutritional status, as well as the risk of metabolic syndrome among elderly (aged 65 and older) household types, using data from the 7th Korea National Health and Nutrition Examination Survey. Across all household types, dietary supplement users had a higher intake of vitamins and minerals, compared to non-users. As a result, a significant decrease was observed in the prevalence of individuals with nutrient intakes below the stimated average requirement (EAR), particularly in single-person and multi-generation households. In single-generation households, non-users had higher HDL cholesterol levels than the other groups, while users had significantly lower cholesterol levels. Adjusting for gender and age, supplement consumption among the elderly decreased the risk of low HDL cholesterol levels, indicating a potential association with lower metabolic syndrome risk (OR=0.798, P=0.006). In conclusion, the use of dietary supplements among the elderly may improve their nutritional status, particularly in single-person and multi-generation households facing higher risks of nutritional deficiencies. In addition, the utilization of dietary supplements can reduce the risk of low HDL cholesterol in single-generation households.

This study aimed to analyze the factors influencing the adaptation of novice nutrition teachers through big data analysis and to propose strategies for enhancing this process. Data were collected from internet portals using the keywords 'novice nutrition teacher' and 'nutrition teacher' from May 25, 2021, to May 25, 2024. Text mining techniques, including frequency analysis, semantic network analysis, and CONvergence of iterated CORrelations (CONCOR) analysis, were employed. Key terms such as 'teacher', 'nutrition', 'career', 'school', and 'school meals' exhibited high frequency and centrality, indicating the multifaceted roles of novice nutrition teachers and the need for increased support. Excessive workload and stress related to school meal management negatively impacted adaptation, highlighting the need for systematic management and capacity-building training programs. Mentoring and consulting systems played a crucial role in enhancing professional development, leading to better adaptation and higher job satisfaction. Additionally, stress and anxiety during the appointment preparation process were significant factors influencing adaptation, suggesting the need for improvements in the training curriculum at teacher education institutions. These findings provide valuable insights for developing policies to support the adaptation of novice nutrition teachers.

This study examined the antioxidant compounds and functional properties of superior potato (SP) after various cooking methods (sun drying: SD, roasting after sun drying: SR, hot-air drying: HD, roasting after hot-air drying: HR, boiling: B, roasting: R, and air-frying: AF) and compared with uncooked SP. As a result, the total phenolic contents (TPC) in the hot water extract (HWE) were the highest in SR. B showed the highest TPC in the ethanol extract (EE). In the α-glucosidase inhibitory activity, S was the highest in the HWE, whereas R was the highest in the EE. At 50 ㎍/mL concentration, AF showed the highest oxygen radical absorbance capacity in both HWE and EE compared to others. SP protected HepG2 cells against H₂O₂-induced DNA damage. Based on the results, the antioxidant compounds and antioxidant activity differed by the cooking method. Thus, the findings from the current study may provide suitable SP cooking methods for attaining their maximum biological activity.

This study examined the sociodemographic and anthropometric data, health-related habits, physical activity, and scores of the Korean Healthy Eating Index according to the obesity of youths aged 19~39 years. Among the subjects of the 2020~2021 Korean National Health and Examination Survey, 2,954 were analyzed. Statistical analyses were used for complex samples using the SPSS software package. The marital status (P<0.001) and economic activity status (P<0.01) of male youth (MY) and the household income level (P<0.01), education level (P<0.01), and economic activity status (P<0.05) of female youth (FY) showed significant differences according to obesity. In MY and FY, age (P<0.001), perceived health status (P<0.001), self-recognized body image (P<0.001), weight change (P<0.001), and weight control (P<0.001) showed significant differences according to the obesity. The prevalence of hypertension (P<0.001), diabetes (P<0.001), hypertriglyceridemia (P<0.001), and hypercholesterolemia (MY P<0.05, FY P<0.001) in MY and FY showed significant differences according to obesity. In MY, the obese group performed higher leisure-related medium-intensity physical activity (P<0.05) than the control group. In FY, the obese group had more stress (P<0.01), lower scores of total fruit intake (P<0.01), fresh fruit intake (P<0.01), and milk and milk products intake (P<0.05) and higher scores of percentages of energy from saturated fatty acid (P<0.05) and total sugar (P<0.05) than the control group. Therefore, the factors associated with obesity in youth differ according to sex, and health promotion programs specified by sex are needed to prevent youth obesity effectively.

This study aims to provide basic data for developing home meal replacement (HMR) products and establishing marketing strategies in Thailand. A survey was conducted targeting Thai consumers who have experience using HMR regularly. The food consumption values were used to segment the Thai consumer market, and the differences in HMR purchase behavior were analyzed according to segment. Thai consumers were divided into three types: high, medium, and low interest in food habits. The main reasons for using HMR among Thai consumers were time-saving, convenience, and cost-effectiveness, with a strong preference for products with high convenience. Among the HMR selection attributes, items such as quality, expiration date, hygiene, safety, taste, nutrition, and freshness are generally important factors for consumers. Among the HMR selection attributes, the items that require improvement first were identified most frequently in the high-interest food lifestyle group and include quality, quantity, additives, ingredients, expiration date, and nutrients. This study is significant because it was conducted targeting the Thai HMR market, where research has been limited, and it revealed the characteristics of segmented markets by reflecting the food consumption value characteristics of Thai consumers. The characteristics of each market segment can be used to develop HMR and marketing strategies that fit the market.

A total of 535 4th~6th grade students in the Gyeonggi area were surveyed in an effort to increase vegetable preference and intake. They were divided into 3 groups according to the frequency of salad consumption (High-frequency group, HF, more than once a week G; Intermediate-frequency, IFG, 1~3 times/month; Low-frequency group, LFG, less than once a month). The proportion of subjects who preferred salad over other vegetable dishes was much lower in the LFG than in the other groups. Compared to the HFG, more students in the LFG gave 'dressing' as the main reason for their preferring salads, and 'because of vegetables in salad' and 'not knowing the necessity of eating salad' as the main reasons. Compared to the HFG and MFG, the proportion of students responding 'less than twice a week' for vegetable and fruit consumption and 'more than 2 hours/day on the internet/games' was higher, while the preferences for namul, salads, saengchae, baechukimchi, chonggakkimchi, nabakkimchi, and fruits were lower in the LFG. The numbers of unfamiliar vegetables and dressings were lower in the HFG than in the other groups and were negatively correlated with the frequency of fruit and vegetable consumption and the preferences for aengchaes, bokkeum, salad, and namul. Also, this study compared the preferences for 14 vegetables and 9 dressings as ingredients of salads by gender, grade, and frequency of eating salads.

This study analyzed the annual changes in the health behavior of obese people and compared the differences according to region. The community health survey data from 2008 to 2019 was used, and statistical analysis was performed using SPSS ver. 25.0. An analysis of obesity for 12 years revealed a decreasing trend for underweight and overweight, while obesity showed an increasing trend and a high rate. From 2010 to 2019, the prevalence of diabetes and hypertension in obese people was 13.0% and 33.5%, respectively, both of which increased. The subjective health level perceived by obese people as very good to good decreased significantly from 40.2% in 2008 to 32.6% in 2019, and the percentage of people who said they were not anxious or depressed increased from 85.3% to 90.2%. The self-awareness of body type of obese people was slightly obese (60.4~65.3%) and very obese (12.2~16.1%), and the weight loss efforts showed an increasing trend from 50.0% in 2008 to 62.3% in 2019. The prevalence of diabetes and hypertension, subjective health status, and weight loss efforts of obese people were higher in the capital region and metropolitan cities, but depression and anxiety tended to be more negative in the capital region than in the non-capital regions. Therefore, it is necessary for the government and local governments to establish policies to reduce the regional gap in the health behavior of obese people.
