Objectives: This study examined the effects of nutrition education on the nutritional status, including eating habits and quality of life in gastric cancer patients undergoing a gastrectomy. Methods: Thirty one out-gastric resection patients at C University Hospital in Gwangju, Korea were enrolled in this study. The patients received an individualized nutritional counseling session, and the effects were assessed before and after a 3-month nutrition education intervention. Nutrition education for gastric cancer outpatients included the dietary guidelines (e.g., food intake), the level of nutrient intake, and nutrition support. Results: The patients had significantly improved serum albumin and hematocrit levels after nutrition education. Of the dietary habits, the meal time and amount of food compared to the first education were increased significantly. Of the changes in the food intake frequency, fish and meat, and vegetables and fruits intake were increased, but not at a statistically significant level. The score of eating habits related to the gastrectomy was improved significantly after nutrition education from 31.7 to 34.5. The composite scores for the quality of life were also improved significantly after the nutrition education program. Conclusions: The nutrition education for gastric cancer outpatients may be crucial and efficient for improving their lifestyle.

Our final goal was to manufacture low-calorie healthy seafood spreads using high pressure processing. Prior to developing the spread products, we performed a nationwide survey of consumers aged in their teens and twenties (n=585). The questionnaire was designed to gain insights from consumers on spread products, including Importance-Performance Analysis (IPA), recipes, market prospects, etc. Consumers responded that 'price, calorie, fat content, sanitary, nutrition, and food additive' should be improved, in that order. They also thought that fruits and vegetables are highly acceptable in recipes of seafood spreads. In addition, consumers pointed that we should concentrate on 'taste, sanitary, flavor, nutrition, and price' to make spreads more successful. Regarding market prospects, consumers rated spreads with scores over 2.96/5.00, which means the market for seafood spreads is sufficient. The consumers' response provided guidelines for developing and manufacturing low-calorie healthy seafood spreads.

This study was conducted to evaluate menu pattern and nutritional contents of snack menus provided by child care information centers in Seoul. Snack menus during March 2013 (morning snack : 125 cases, afternoon snack : 100 cases), including information on portion size, were collected from five child care information centers, after which the number of menu items, menu patterns, and nutritional contents were analyzed. About two-thirds of total snack menus included two menu items. There were significant differences in service time (morning & afternoon snacks). 'Beverage+Food' pattern (66.7%) was the most commonly used; 'Beverage' pattern was significantly higher in morning snacks (10.4%) than in afternoon snacks (1.0%). Morning and afternoon snacks provided 124.5 and 170.6 kcal of energy and 116.4 and 90.9 mg of calcium, respectively, which are 8.9% and 12.2% as well as 19.4%, and 15.2% of children's daily energy and calcium requirements. To improve the quality of food and nutrition offered to children through snacks at child carre centers, a more detailed snack menu plan as well as nutritional guidelines for institutions should be developed.

This study was intended to investigate the sodium-related perception, dietary behavior, and practicability of methods for reducing sodium intake(RSI) according to the stage of change in consumers. The survey was conducted to 770 housewives, among them 553 subjects who answered the key questions for the stage of change were categorized into 'Maintenance (M)' stage (maintaining reduced salt intake for more than 6 months; n = 287, 51.90%), 'Action (A)' stage (maintaining reduced salt intake for less than 6 months; n=139, 25.14%), and 'Pre-Action (P)' stage (not starting reduced salt intake; n = 127, 22.97%). The subjects in M and A were significantly older than those in P (p < 0.01). The scores of desirable dietary habit and dietary balance were the highest in M followed by A and P. When eating out, the subjects in P considered 'price' more and 'healthiness of food' less than those in M and A did. Among the guidelines for RSI, 'Avoid Processed Foods', 'Eat enough vegetables and fruits' and 'Add little amount of dipping sauce for fried food' were selected as the three easiest items to perform. With regard to the sodium-related perception, the subjects in M considered eating-out food to be more salty than homemade dishes, read nutrition labels more, avoided table salt or dipping sauce for fried food more, and had 'own low-sodium recipe' than those in P (p < 0.001). It is suggested that practicability of actions for RSI and the stage of change should be considered to develop effective personalized education program and nutrition guidance.

Purpose: This study aimed to analyze the trends in kimchi, vegetable, and fruit consumption among the Korean population and identify the factors associated with this consumption. The goal was to provide fundamental data for developing appropriate guidelines to increase kimchi consumption by understanding its characteristics. Methods: The analysis utilized data from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted between 1998 and 2020. A total of 81,680 adults, aged 30 years or older, were included in the trend analysis. For the analysis of factors associated with kimchi, vegetable, and fruit intake, a subgroup of 22,122 adults aged 30 years or older from the KNHANES (2016-2020) was divided into two groups: 30-64 years old and 65 years old or older. Since the KNHANES data employed a complex sampling design, the statistical analysis was conducted using the appropriate complex sampling design method. Results: The overall consumption of kimchi exhibited a declining trend among both men and women. Specifically, there was a significant decline in the intake of baechu kimchi among both genders. The decline in kimchi consumption above the standard was associated with a decrease in meal frequency and an increase in the frequency of eating alone. However, the patterns for unsalted vegetables and fruits differed compared to kimchi. Conclusion: In this study, there was a decline in kimchi consumption among both men and women, and the potential factors associated with this trend included Westernized dietary habits, the presence of a spouse who influenced dietary habits, and an increased frequency of solitary dining due to the rise in single-person households. Therefore, it is necessary to develop dietary guidelines that consider these factors.

This survey was carried out to obtain the information concerning nutritional status, including factors of food habits and nutrient intake of the long-lived elderly men and women living in Ganghwa-gun. In order to assess the quality of dietary intake among the elderly, a survey was conducted during December 2003 of 103 subjects who were over 85 years of age. Dietary nutrient intake data were obtained through the 24 hr recall method. Chi-square test and t-test were the main data analysis method. Their dietary habits such as three meals a day and a regular meal time have shown that they have generally good eating habits. Average daily calorie intake ($\%$ RDA) was 1233.2 kcal ($68.8\%$) for male and 1215.8 kcal ($75.8\%$) for female which were lower than the Recommended Dietary Allowances (RDA) for Koreans. Energy intake of females got closer to RDA than that of male. Protein intake was 49.3 g for male and 46.9 g for female (which was $82.3\%$ RDA for male and $85.1\%$ RDA for female) for elderly person, the proportion of animal protein to total protein intake were $45.2\%$ for male and $39.0\%$ for female. Average CPF ratio of energy intake for both male and female were 68.7 : 16.1 : 15.2 and 69.6 : 15.4 : 15.0. SFA : MUFA : PUFA ratio of the subject was 0.78 : 1.03 : 1.00 for male and 0.64 : 0.92 : 1.00 for female. Calcium intakes for both males and females were 321.3 mg and 377.2 mg. Vitamin A was the nutrient found to be least sufficient. Mean daily intakes of most of the vitamins and minerals for both males and females were lower than RDA except vitamin C and Zn for female, especially $\%$ RDAs of vitamin A, Ca for male and vitamin A for females were less than $50\%$ of RDA. In conclusion, long-lived elderly in Ganghwa areas did not consume enough nutrients quantitatively as well as qualitatively, especially Ca, Fe, vitamin A, vitamin $B_2$ and vitamin E. These results suggest that nutritional guidelines for older Koreans should focus on the maintenance of adequate energy intake. In addition, selection of foods with high protein and calcium, such as dairy food, should be emphasized, particularly in the long-lived elderly.

BACKGROUND/OBJECTIVES: This study was conducted to examine relationships between dietary habits and intakes of antioxidants and B vitamins and the risk of ischemic stroke, and to compare dietary factors according to the presence of cerebral artery atherosclerosis and stroke subtypes. SUBJECTS/METHODS: A total of 147 patients and 144 control subjects were recruited consecutively in the metropolitan area of Seoul, Korea. Sixty participants each in the case and control groups were included in analyses after 1:1 frequency matching. In addition, 117 acute ischemic stroke patients were classified into subtypes according to the Trial of Org 10172 in Acute Stroke Treatment (TOAST) guidelines. Dietary intake was measured using a semi-quantitative food frequency questionnaire composed of 111 food items and plasma lipid and homocysteine levels were analyzed. RESULTS: When compared with control subjects, stroke patients had unfavorable dietary behaviors and lower intakes of fruits ($73.1{\pm}83.2g$ vs. $230.9{\pm}202.1g$, P < 0.001), vegetables ($221.1{\pm}209.0g$ vs. $561.7{\pm}306.6g$, P < 0.001), and antioxidants, including vitamins C, E, $B_6$, ${\beta}$-carotene, and folate. The intakes of fruits, vegetables, vitamin C, and folate were inversely associated with the risk of ischemic stroke after adjusting for confounding factors. Intakes of vegetables, vitamins C, $B_6$, $B_{12}$, and folate per 1,000 kcal were lower in ischemic stroke with cerebral atherosclerosis than in those without. Overall vitamin $B_{12}$ intake per 1,000 kcal differed according to the TOAST classification (P = 0.004), but no differences among groups existed based on the post-hoc test. CONCLUSIONS: When compared with control subjects, ischemic stroke patients, particularly those with cerebral atherosclerosis, had unfavorable dietary intake, which may have contributed to the development of ischemic stroke. These results indicate that proper dietary recommendations are important for the prevention of ischemic stroke.

Objectives: This study was designed to investigate the relationship between metabolic risk factors, Index of Nutrition Quality, and the dietary quality index score of Korean adults. Methods: The subjects were 18,652 Korean adults aged 19 years or older (7,899 males, 10,753 females) who participated in the 2016-2019 Korea National Health and Nutrition Examination Survey. Subjects were divided into normal, pre-metabolic syndrome, and metabolic syndrome (MetS) groups according to the number of their metabolic risk factors. Data were analyzed using the SPSS program. Results: About 44.7% of men in the MetS group were at least college graduates (P < 0.001), whereas 52.0% of women in the MetS group were middle school graduates or lower (P < 0.001). The frequency of fruit and dairy products intake tended to decrease as the number of metabolic risk factors increased in both men and women (P for trend < 0.001). As the number of metabolic risk factors decreased, the frequency of grain intake tended to decrease in men (P for trend < 0.001) while the frequency of intake of red meat (P for trend = 0.001), poultry (P for trend < 0.001), and eggs (P for trend < 0.001) decreased in women. The total scores of Diet Quality Index-International (DQI-I) (men P < 0.001, women P < 0.01) and Korean Healthy Eating Index (KHEI) (men and women P < 0.001) were significantly lower in the MetS group compared to the other groups, and the total score of DQI-I and KHEI tended to decrease as the number of metabolic risk factors increased. Conclusions: Dietary quality evaluation using various indices can provide more information on the dietary problems related to metabolic risk factors. Nutrients and foods that have been confirmed to be related to metabolic risk factors can be used to develop dietary guidelines for the nutritional management of metabolic diseases.

This study evaluated the dietary habits and dietary quality of the Korean elderly according to muscle strength status. This study was conducted on the elderly aged over 65 years who participated in the 2014-2018 Korea National Health and Nutrition Examination Survey. Subjects were classified into the normal muscle strength group(n=2,000) and the low muscle strength group(n=1,273) according to the handgrip strength. There was a significant difference in general characteristics, diet habits, and health behavior according to the muscle strength status. The normal muscle strength group had a higher total score of KHEI and a subtotal score of 「adequacy」 items. But there was not significant difference in the 「moderation」 items. For the 「balance of energy intake」 items, the normal muscle strength group had a higher subtotal score than the low muscle strength group only in among women. The prevalence of low muscle strength decreased in the highest quartile of the adjusted KHEI total score(p for trend=0.08). As a result of this study, it was found that KHEI was significantly associated with muscle strength. This study result can be used to provide dietary guidelines for the improvement of muscle strength in the elderly based on each item of KHEI and sex.

BACKGROUND/OBJECTIVES: Accumulating evidence has shown the beneficial effects of isoflavone on health. There is limited information on the usual isoflavone intake for Koreans. This study examined the usual intake of total isoflavone and its major food sources in Koreans according to age and gender. SUBJECTS/METHODS: The dietary intake data of 21,271 participants aged 1 yrs and older from the Korea National Health and Nutrition Examination Survey (KNHANES) VII 2016-2018 were analyzed. The average isoflavone intake was estimated based on the 24-h dietary recall data in KNHANES and the isoflavone database from the Korea Rural Development Administration (RDA) and literatures. The usual isoflavone intake was estimated by applying the ratio of within- and between-participant variance estimated from the 2009 KNHANES data to the 7th KNHANES (2016-2018) data. The variance of the isoflavone intake was calculated using MIXTRAN macro with intake data for two days in the 2009 KNHANES. Complex sample analysis with stratified variables and integrated weights was conducted. RESULTS: The mean total isoflavone intake in the Korean population aged 1 yrs and older (n = 21,271) was 139.27 mg/d, which was higher than the usual intake of 47.44mg/d. Legumes were a major contributing food group (91%), with arrowroot being a major individual contributor to the isoflavone intake (67.2%), followed by 21.3% of soybean, 5.4% of bean sprouts, and 2.1% of tofu. The usual isoflavone intake was highest in the participants aged 50 to 64 yrs old and increased with age until 50 to 64 yrs and then decreased with further increases in age. The usual isoflavone intake of participants aged 65 yrs and older was higher for men than for women, showing gender differences. CONCLUSIONS: The usual dietary intake of isoflavone varied according to age and gender in the Korean population. This study showed that the usual isoflavone intake was lower than the average isoflavone intake. The difference between percentiles of the usual isoflavone intake was similarly smaller than the average intake. An estimation of average intake can be hindered by the occasional consumption of foods high in isoflavones, suggesting that the usual intake estimation method can be more appropriate. Further research will be needed to establish isoflavone dietary guidelines regarding the effects of isoflavone intake on health outcomes.
