Purpose: This study was conducted to conduct dietary assessment of Korean adults according to intake of Korean soup and stew. Methods: To accomplish this study, 20,926 adults aged 19 yr or higher who participated in the dietary intake survey (24 h recall method) were analyzed from the data of the 2011~2014 Korea National Health and Nutrition Examination Survey (KNHANES). The items included in the soup and stew were guk, tang, jjigae, jijimi, and jeongol. Results: Intakes of soup and stew of subjects were divided into quartiles; intake range by quartile was Q1: < 22.96 g, Q2: 22.96~98.75 g, Q3: 98.75~212.23 g, and Q4: $${\geq_-}212.24g$$. In the case of the Q4 group, male, married, employed, higher educated, and high income subjects showed increased intakes of soup and stew. In addition, sodium intake among nutrient intakes increased from 3,849.04 mg in Q1 group to 5,363.57 mg in Q4 group. Intakes of cereals/grains, potatoes/starches, legumes, seeds/nuts, vegetables, mushrooms, fruits, meat, fishes/shell fishes, milks/dairy products, oils/fats, and seasonings among all foods significantly increased from Q1 group to Q4 group. Lastly, in the multivariable regression analysis, male, higher age, married, eating breakfast, consumption of snacks, prepared meals from home/institution, average eating-out frequency per week, energy consumption, and sodium intake related parameters increased intake of Korean soup and stew. Conclusion: Excessive intake of sodium was related to high blood pressure and metabolic syndrome. Thus, there are needs to improve dietary guidelines and nutrition education for balanced intake of soup and stew.

This study examined the nutrient content of HMR products and recipes by television chefs. Twelve menu items from the soup, stew, and broth category were chosen from HMR products and TV chef's recipes. The data on the nutrition labeling from the HMR products and TV chef's recipes were calculated using Can-Pro 5.0. The results of the analysis were the differences between the HMR products and TV recipes per serving size. The energy content of TV recipes 236.1 kcal was significantly higher than the HMR products. On the other hand, HMR products contained significantly higher sodium (926.9 mg) levels than the TV recipes (565.8 mg). In general, HMR products contained more sodium and less energy and protein than TV recipes. The highest sodium content containing products among the 12 menu items was the Spicy soft tofu stew (1,421.4 mg) from HMR products. The results revealed the significant differences in the macronutrient and sodium content between HMR products and the TV chef's recipe. This study provides supportive data for the need to reduce the sodium content in HMR products. TV cooking programs should focus on the importance of balanced nutrition, how to reduce sodium intake, and how to achieve this without disrupting well-balanced nutrition.

Purpose: The purpose of this study was to investigate the differences in portion size of 11 types of foods that Korean adults frequently consume, based on the parameters of eating place, gender, and age using the Korea National Health and Nutrition Examination Survey (KNHANES) data. Methods: The dietary survey data from 2012-2016 KNHANES was used. A total of 19,779 subjects (8,034 male [40.6%], 11,745 female [59.4%]) were classified based on gender, three age groups (19-29 years old [15.7%], 30-49 years old [46.9%], 50-64 years old [37.4%]) and three eating places (home, institution, and restaurants/convenient stores etc.). Results: The portion sizes according to the eating places were calculated as per the median intake of Korean adults. Foods that showed the highest median intake in restaurants/convenience stores were boiled rice and kimchi stew. The median intake quantity of kimchi stew was the highest in restaurants/convenience stores in men across most age groups. Women in 30-49 years age group also consumed a lot of kimchi stew in restaurants/convenience stores. Men in the age groups 30-49 and 50-64 years consumed soybean paste stew the most in institutions compared to home and restaurants/convenient stores. Stir-fried pork was consumed the most at institutional meal places across all age groups. Conclusion: The portion sizes of kimchi stew and boiled rice were the highest in restaurants/convenience stores. As kimchi stew and soybean paste stew is high in sodium, the intake should be reduced in institutions and restaurants/convenience stores. Furthermore, it is necessary to reduce sodium intake through consumer nutrition education and the development of low-salt standard recipes for restaurants.

Purpose: This study investigated the salt and sodium content of lunch meals served at foodservice center for children in Gyeongsan-si, Gyeongsangbuk-do. Methods: Five foodservice centers for children registered at Center for Children's Foodservice Management were investigated for salt and sodium content and salt content contributing rate per meal. Results: Average salt content of every meal was $1.78{\pm}0.54g$, and average sodium content was $680.99{\pm}175.97mg$. The 98 of 100 meals served in 5 foodservice centers for children exceeded the dietary reference intakes for Koreans' recommendation for adequate intake of sodium per meal of 333 mg. The highest sodium content was 1,369.85 mg. Samples from lunch meals were classified into 14 food items and investigated for one serving size, salinity, salt and sodium content. Total average salinity was 0.31%, kimchi (0.49%), followed by soup (0.45%), hard-boiled foods (0.39%), stir-fried foods (0.39%), and fresh-vegetables (0.32%). Total average salt content was 0.39 g, the most salty dishes were one-dish rice noodles, followed by soup (0.65 g), hard-boiled foods (0.49 g), stir-fried foods (0.48 g), and broth stew (0.43 g). Samples from lunch meals were classified into 6 menu groups, including cooked rice, one-dish rice noodles, soup stew, main dish, side dish, and kimchi. Contributing rate for total average salt content was high in one-dish rice noodles (48.97%), soup stew (38.47%), main dish (27.28%), side dish (21.02%), kimchi (18.56%), and cooked rice (3.95%). Conclusion: These results can be useful for reducing total dietary sodium content to less than 333 mg in children who are provided lunch meals at foodservice centers. To achieve this goal, development of low-sodium recipes, and nutrition education for foodservice employees is required.

This study was conducted to investigate the menu patterns consumed frequently in 5 Korean rural areas for all seasons, using 24-hour recall method with 1,185 subjects. The purpose of this study was to suggest the menu pattern in rural areas for the basis data of the nutrition education program and nutrition intervention project. The result were following : most frequently used menu patterns by the number of side dish were rice + soup + kimchi + 1 side dish> rice + soup + kimchi + 2 side dish> rice + soup + kimchi > rice + stew + kimchi + 1 side dish in the order. Most frequently used menu patterns by the kind of side dish were rice + soup + kimchi > rice + stew + kimch > rice + kimchi> noodle + kimchi in the order. In menu patterns showed higher frequency, Nutrient Adequacy Ratio(NAR) of all nutrients except Ca and Vit A was over 0.7. The Mean Adequacy Ratio (MAR) of rice + soup(or stew) + kimchi + 2(or 3) side dish was 0.76∼0.82. The number of dishes consumed in winter was the highest. The menu had traditional menu pattern based on cooked rice, Korean soup and kimchi in Korean rural areas. With these results, we can conclude that nutrient balances from the menu pattern can be improved, if the composition of main dish and side dish are adequate . For the nutrition program in the community menu patterns should be examined carefully. The result from this study can be used as basic data for nutrition education programs in Korean rural areas.

This study was done to explore the effect of Korean women's salt usage behavior on their sodium intake and excretion according to aging. Dietary sodium intake and salt usage behavior were analyzed to compare the difference between young and middle-aged women. One hundred fifty six young women and 77 middle-aged women without hypertension or any current medication were recruited. Body mass index, waist hip ratio, blood pressure were measured from each subject. Salt usage behaviors were surveyed with questionnaire, sodium intake with 24-hr recall method, and sodium excretion with spot urine. Middle-aged women were more obese than young women according to body mass index and waist hip ratio. Blood pressure was significantly higher for the middle-aged. Young women consumed more fats and middle-aged women more carbohydrates. Middle-aged women consumed more sodium and potassium, and excreted more sodium. Among questionnaire items, kimchi, soup or pot stew, or salted vegetables were found to be related with high sodium diet. Salted vegetables and salted nuts and potato chips were significantly correlated with young women's high sodium diet, while soy sauce on fried food, kimchi, salted vegetables accounted for middle-aged women's high sodium diet. With these results, we concluded that middle-aged women consumed more carbohydrates, less fat, and more sodium and potassium than young women. Middle-aged women frequently choose kimchi, soup or pot stew, or salted vegetables, and they contribute to high sodium intake. We recommend to choose low-salt kimchi, less soup or pot stew, and more fresh vegetables for lower sodium diet.

Objectives: The purpose of this study was to evaluate the main sources of dietary sodium and potassium intake in Koreans by gender, age and regions. Methods: We used the data from 2010-2012 KNHANES. A total of 20,387 subjects aged 8 years and older were included. Intakes were compared by gender, age (8-18, 19-49 and >50 years) and geographical regions in Korea. Dishes were classified into 28 dish groups based on cooking methods. Statistical analysis was performed by using the SAS 9.3 and SUDAAN 11.0.1 software. Results: The mean sodium intake of Koreans was $4866.5{\pm}35.9mg/day$, which was 2.4 times higher than the adequate intake (AI) of sodium for Koreans. We found that daily sodium intakes were significantly different by age, gender and regions. Men and aged over 50 years had significantly higher sodium intake than women and other age groups. The mean potassium intake in Koreans was $3002.2{\pm}19.4mg/day$ and daily potassium intakes were significantly different by age, gender and regions. Women and age 50 years and over had significantly higher potassium intakes than men and other age groups. The average Na/K ratio was $2.89{\pm}0.01$ and was highest in men and in the age group of 19-49 years. The major sources of dietary sodium were soup and stew, followed by Kimchi, noodles and dumpling, pickled vegetables and seasonings, which represented 63.1 % of total sodium intakes. Soup and stew or Kimchi were the primary sources of dietary sodium intake. The major sources of dietary potassium were cooked rice, followed by soup and stew, Kimchi, fruits and beverages. Conclusions: Sodium and potassium intakes and the major sources of those were significantly different by gender, age groups and regions. Therefore, different approaches based on gender, age and regions are needed to decrease sodium intake and increase potassium intake.

This study aims to find out the devices to minimize the amount of nitrate ingested from kimchi, the main way of vegetable intake for Koreans, and the basic data to deliver to calculate the total daily intake for Korean, investigating the year-round changes of nitrate content in vegetables for Kimche raw material, and changes of nitrate content by salting of chinese cabbage, and stewed kimchi through the use of different cooking methods. The results obtained were summarized as follow: over between 205-6655mg/kg f.w. in chinese cabbage, 480-3970mg/kg f.w. in chinese radish, 157-5820mg/kg f.w. in lettuce and 29-520mg/kg f.w. in cucumber respectively. Therefore it was strongly adviced to introduce the nitrate limit value of vegetables in Korea if the nitrate content in Kimchi should be reduced to meet the nitrate ADI(Acceptable Daily Intake, 219mg60kg b.w) of FAO.WHO, because the nitrate content in Kimchi reflects the nitrate content in vegetables. In order to keep the low nitrate content in Kimchi. it was adviced to remove the outer leaf which contains 2-3 times higher nitrate content compare to the inner leaf at the time of preparation, i.e. chinese cabbage, before the soaking treatment in salt solution for Kimchi making process. The dehydration by soaking treatment in salt solution occurred at 0.9%~4.7% in leaf midrib and more than 13%~24% in leaf blade. The nitrate content after soaking in salt solution was increased 107%~123% compared with before soaking, increasing rates of nitrate content in the outer and inner leaf midrib were higher than those in leaf blade. The increase of nitrate content in salt solution after soaking due to the dehydration of chinese cabbage by soaking treatment. The Kimchi stew(Kimchi JJige) was processed with and without animal oil, but the amount of nitrate in kimchi stew did not decrease both treatments, but it increased after the processing since the water in Kimchi stew has got low by boiling.

Dietary habit of excess sodium consumption is formed mainly by excessive salt intake from the younger age and this may lead to hypertension, stroke, and stomach cancer. This study was performed to estimate the salt content in kindergarten meals and provide basic data on meal providers' dietary attitude to sodium intake for nutrition education. We collected data on161 food items from 16 institutions in Gyeonggi-do and salt content was calculated from salinity and weight of individual food items. The average salt content from lunch meals was 2.2 g, which was about daily adequate intake of sodium for children aged 3 to 5 years old. Greatest contributor to the salt content in a meal was soup and stew (47.8%). The most salty dishes were sauces and kimchi followed by stir-fried food, deep-fried food, braised food, and grilled food. The salt content was higher in soup and stew despite of low salinity, due to the large quantity per serving. The salt contents of soups and kimchi were 40.6% and 14.3%, respectively of the total salt content in dish groups. Staff members and caregivers at home who prepared food for the child showed preference for one-dish rice meal, dried fish and salted mackerel, and broth when eating soup, stew, and noodles. Caregivers showed higher sodium index score and had higher preference for processed food such as Ramen, canned food, and ham compared with staff members (p < 0.05). These results suggested that monitoring salt content of kindergarten meals and nutrition education for those prepare meals for children are needed to lower sodium intake in childhood.
