Objectives: Vegetables are the most left over side dishes in school lunch programs. This study intended to analyze the differences in preference for vegetables among the students of different age groups in order to determine potential ways of increasing vegetable consumption in this study group. Methods: A total of 308 primary to university students in Gyeongbuk area were recruited and a questionnaire-based survey was conducted. The preference score (7-Likert scale: very much dislike (1)~so-so (4)~like very much (7)) and intake frequency (5-Likert scale) of 48 kinds of vegetables in 4 vegetable groups, such as vegetable (fruit-, root-, leaf-, and stalk-vegetable), seaweeds, mushrooms, and kimchi were investigated, and data were analyzed by SPSS WIN (ver 12.0). Results: The preference scores of vegetables except for seaweeds were significantly different among school groups, university was the highest, followed by high school. Primary and middle school students showed the lowest preference score, especially for leaf- and stalk- vegetables. The preference score for seaweeds was the highest of 5.28, followed by kimchi of 4.99. With regard to kimchis, the preference score was the highest in university', followed by high school, middle school, and primary school' was the lowest. The number of vegetables with < 4.0 preference score was the highest in primary school of 16, 15 in middle school, 11 in high school, and 7, the lowest in university. The vegetable with preference score of < 4.0 in all 4 school groups were mallow, chard, bud, radish leaf, mugwort, butterbur and sweet potato stalk. With regard to the intake frequency of vegetables, kimchis, an indispensable part of the Korean diet, was the highest of 2 times/day, followed by cooked vegetables of 1.5 times/day. The correlation coefficients between preference scores and intake frequencies were statistically significant in all groups of vegetables. As for the coefficient of variation (CV) of preference score, primary school' was the highest and university' was the lowest. The number of vegetables with high CV and high inexperience were highest in primary school students. Conclusions: Providing more opportunities for consuming a variety of vegetables, such as leaf- and stalk-vegetable, it may be possible to increase vegetable consumption, especially for the primary school students.

Objectives: The objective of the study was to examine the clustering patterns and correlates of multiple health behaviors (MHBs) in middle-aged Koreans with metabolic syndrome (MetS). Methods: Data on sociodemographics, clinical characteristics, health behaviors (vegetable intake, physical activity, cigarette smoking, and alcohol consumption), and psychological characteristics were collected by a self-reported survey and medical examination from 331 individuals with MetS. Clustering of MHBs was examined by measuring 1) the ratios of observed and expected prevalence of MHBs, and 2) the prevalence odds ratios. A binomial logistic regression were conducted. Results: Men were more likely than women to engage in multiple unhealthy behaviors. Clustering of smoking and heavy drinking was exhibited in the participants. Women with high vegetable intake were more likely to be physically inactive, and those with inadequate vegetable intake were more likely to be physically active. Those with lower self-regulation were more likely to engage in unhealthy behaviors. Conclusions: The findings support the multiple health behavior approach as opposed to the individual health behavior approach. Emphasis of self-regulation is necessary in developing multiple behavior intervention for individuals with MetS.

The purpose of this study was to develop and apply the dietary education program for prescehoolers to improve their vegetable intakes. In this study, 134 mothers of preschoolers were surveyed about the problem of unbalanced food habits in children. A nutrition education program was developed based on the survey results, and then applied in the field to evaluate the effects of nutrition education. Most preschoolers (79.9%) had a relatively low intake of vegetables. The main reason for their unbalanced eating of vegetables was due to texture (34.6%) and taste (30.8%). The activity-based nutrition education program to increase vegetable intake consisted of four lessons. After the nutrition education program was administered for 43 preschoolers, their nutrition knowledge score significantly increased (P<0.001). Preschoolers found the lessons fun (90.9%) and interesting (81.4%), and said they would eat more vegetables in the future (88.4%). This study demonstrates that the unbalanced diet of preschoolers could be modified through the proper introduction of an education program.

Ascorbic acid has a strong power to reduce other materials, so by using this reducing power we can analise many materials quantitatively. Dihydro-ascorbic acid is quantitatively changed into ascorbic acid under a certain condition, if reduced by hydrogen-sulfide. Dihydro-ascorbic acid also has physiolosical effect, but less effect than ascorbic acid. The effect of dihydro-ascorbic acid is regarded as a half of that of ascorbic acid. Among the analytical methods applying this theory the method using 2.6 dichlorophenol indophenol what called the method of Indophenol is used most widely; so does Hydrazine-method. But comparing these two methods the former shows a little higher rate in analytical value. Vegetable are vital sources for vitamin C. According to the report of the commitee of FAO Korean branch the amount of daily per head average intake of vitamin C is about 70mg in raw materials. Since vitamin C is easily affected by heating or oxidation in Cooking the loss is not a little. Consequntly it is regarded that the actual amount of intake will be much less than basic amount. It is therefore very important to find out that how much percent of the loss there will be in case of cooking, in order to dicide the actual amount of in take as proper nutrition for a person. Therefore this paper intended to give some help in setting a standard amount of V.C intake, by measuring the change of the V.C amount using the general cooking method and by measuring amount of V.C contained in the part of vegetable, used in Korea abundantly.

This study investigated the correlation between parents' nutrition quotient (NQ) and the nutrition quotient of Korean preschoolers (NQ-P) of picky eaters (PE) aged five years living in Dobong-gu, Seoul. The questionnaire was conducted online by parents of 187 preschoolers between May 25 and June 5, 2020. PE was defined as an average score of 3 or more on the picky eating questionnaires; non-picky eaters (NPE, n=120) and PE (n=67). The correlation between preschoolers and their parents was assessed using the NQ-P and NQ, respectively. Compared to the NPE, picky eating (p<0.001) was significantly higher, and vegetable preference (p<0.001), NQ-P (p<0.05), moderation dimension (p<0.05), frequency of vegetable intake (p<0.05) of balance dimension, and processed beverages (p<0.01) of moderation dimension were significantly lower in the PE. The correlation between the NQ and NQ-P was related to the diversity (p<0.05), moderation (p<0.05), and environment (p<0.01) of NQ in the NPE and not related to the PE. PEs should increase their frequency of vegetable intake and reduce their intake of processed beverages. To increase the NQ-P of PE, parents should eat a balanced diet. Future studies on the NQ-P of preschoolers aged 3 to 5 are needed.

The purpose of this study was to identify the influence of diet related factors, such as diet behaviors, food intake, and nutrient intakes, on self-rated health (SRH). Also, in order to determine fitness of classification for SRH reflecting diet related factors, this study surveyed older adults in Gyeongnam province. A total of 101 responses were collected using the interview survey method. The self- rated health of rural older adults was poor as reported by 49.5%. The level of self-rated health was found to be related to the frequencies of coffee and snack, use of sugar and vegetable in diet, the amount of total food intake, and cholesterol intake. The result of discriminant analysis, which was conducted to assess the adequacy of SRH classification and to determine the class of observation, showed frequency of coffee and use of vegetable in diet among 47 variables as predictive variables for explaining SRH. The fitness of self-rated health function was high to 47.7%. Therefore, diet-related factors were ascertained to be important variables to predict SRH.

Consumption of vegetables and fruits is associated with a reduced risk of stroke, but it is unclear whether their protective effects are due to antioxidant vitamins or folate and metabolically related B vitamins. The purpose of the study was to test the hypothesis that intake of fruits and vegetables, which are major sources of antioxidant and vitamin B complex vitamins, reduces the risk of stroke. Cases consisted of patients diagnosed with first event of stroke (n = 69). Controls (n = 69) were age-, sex-, and body mass index-matched to cases. Multivariable-adjusted regression analysis showed that subjects who ate four to six servings of vegetable per day had a 32% reduction in the risk of stroke, and those with more than six servings per day had a reduction of 69% after adjusting for age, sex, BMI, and family history of stroke. Intakes of total fat, plant fat, calcium, potassium, vitamin $B_1$, vitamin $B_2$, vitamin $B_6$, niacin, and folate were significantly and negatively associated with the risk of stroke. Although the trend was not significant, stroke risk was reduced in the second quartile (1.21-2.66 servings per week) of fish intake. However, intake of fruits (average daily intake of 1.0 serving) and antioxidant vitamins such as carotene, vitamin C, and vitamin E was not associated with the risk of stroke. In conclusion, our observational study suggests that intake of fat and vegetables, rich sources of vitamin B complex, calcium, and potassium may protect against stroke.

The purpose of the study was to compare the satisfaction level on hospital meal size and actual intake rate of hospital foods between elderly and middle aged patients. Sixty one middle aged and one hundered thirty two elderly patients were surveyed on the foods served in the hospital-rice, soup, meat/fish, vegetable, kimchi and daily products. Compared to the middle aged patients, the more elderly thought the serving size of rice was too big(p<0.05), and those of soup, meat/fish and kimchi tended to be too big. There was no difference in the satisfaction level on the serving size of vegetable dish between two age groups. In actual intake rates of hospital meal there were no significant differences between the elderly and middle aged patients. However, the elderly male ate significantly(p<0.05) less amount of rice than the middle aged male and the elderly female ate significantly(p<0.01) less amount of meat/fish then the middle aged female. Satisfaction levels and actual intake rates were significantly correlated in all food items.
