In this study, we investigated protection motivation and behavioral intention to prevent serious illnesses related to excessive sodium intake among the university students in Gyeongnam and Busan. Within the protection motivation theory (PMT) framework, a survey questionnaire was developed to measure participants' perceptions on the severity of and the vulnerability to the threat of serious diseases due to the high sodium intake as well as the effectiveness of preventive measures (response efficacy), and the ability to perform them (self-efficacy) along with their willingness to follow recommendations (behavioral intention). Data was collected in June 2015. Study participants were divided into either low (n=117) or high (n=177) sodium intake behavior groups based on their current behaviors. Exploratory factor analysis was performed to measure construct validity and Cronbach's alpha was calculated to check reliability of measurement items. The high sodium intake behavior group perceived higher vulnerability than the low sodium intake behavior group among four PMT factors. Differences of the other three factors were not significant between the two groups. The results of hierarchical regression analysis indicated that self-efficacy and response efficacy affected behavioral intention of high sodium intake behavior among students. Hence, development of strategies to increase self-efficacy and response efficacy are strongly recommended.

This study was conducted to determine the salt-intake from meals that were served by an institutional foodservice establishment for a month. Meals (176) were classified into 12 food groups by CAN Pro 3.0. These consisted of bap 6, mandu 5, guk 29, jjigae 9, jjim 4, gui 8, jeon 5, bokeum 25, jorim 16, fried 7, namul 49, pickled 12. The average salt content of 100 g of each menu item was significantly higher in the order of pickled>jorim>bokeum>gui>namul>jeon>jjigae>jjim>fried. The average salt and sodium contents of 1 potion of menu item was significantly higher in the order of jjigae>mandu>guk>bap>jorim>pickled>bokeum>gui>fried>jjim>gimchi>namul>jeon. The average salt contents of kim-chijjigae (6.05 g), eggjorim (7.01 g), cooked namul (2.78 g) and salted pepperleaves (4.67 g) was higher than that of the other menu items served frequently in the establishment. The average intake of salt and sodium was 23.48 g (sodium 9,310 mg) a day, 7.35 g (sodium 2,960 mg) with breakfast, 7.55 g (sodium 2,990 mg) with lunch and 8.33 g (sodium 3,300 mg) with dinner. The daily salt intake was slightly higher than that of DRIs (Dietary Reference Intakes).

This study was conducted as a nationwide project in order to obtain data on the content and intake of sodium in school meals. For this purpose, we selected two elementary and two middle schools in Daejeon as well as four elementary schools in the Chungcheong area. We measured the sodium and potassium contents of 842 dishes as well as their intake levels over 154 days. Sodium content was analyzed using an AAS (Atomic Absorption Spectrometer). The average meal intakes of second and fifth grade elementary school students were 244 g/meal and 304 g/meal, respectively. The meal intake of middle school students was 401 g/meal. Boys tended to eat slightly more than did girls, and students tended to eat more in the spring than in the summer. The average sodium intake per meal was 642 mg (570 mg by elementary school students, 1068 mg by middle school students), which was 32.1% of the UL (Tolerable Upper Intake Level, 2,000 mg per day) according to the KDRIs (Dietary Reference Intakes for Koreans). The sodium intake per meal was not significantly differ between boys and girls or between spring and summer (p>0.05). This study provides fundamental data that can be used to establishment a nutrition policy concerning the adequate content of sodium in school meals.

Purpose: This study aimed to examine the compliance to a low-salt diet, sodium intake, and preferred salty taste in elderly patients with hypertension. Methods: A cross-sectional descriptive design was used. Participants were 105 elderly patients with hypertension living in a rural area. The compliance with a low-salt diet, sodium intake, and preferred salty taste, blood pressure, body mass index, and waist circumference were measured, and compared according to the general characteristics and the levels of blood pressure. Descriptive statistics, $X^2$-test, t-test, and ANOVA were used for data analysis. Results: compliance with a low-salt diet was marginally elevated. Sodium intake was relatively high and the main sources were seasonings and vegetables. The participants tended to prefer high levels of salt. Sodium intake was significantly higher the hypertensive individuals (stage I and II) compared to prehypertensive subjects on a normal maintenance diet. Sodium intake from vegetables was also significantly different between the two groups. Conclusion: Nursing intervention for hypertensive elderly patients should include strategies to decrease sodium intake.

The aim of this study was to investigate the effects of dietary sodium nitrite and meat on human health. Sodium nitrite in processed meat is known to be one of the main precursors of carcinogens, such as N-nitroso compounds. However, we previously found that processed meat is not the primary source of sodium nitrite; nitrate or the conversion of nitrate in vegetables are contribute to generate more than 70% Sodium nitrite or nitrate containing compounds in body. Although the heavy consumption of meat is likely to cause various diseases, meat intake is not the only cause of colorectal cancer. Our review indicates that sodium nitrite derived from foods and endogenous nitric oxide may exhibit positive effects on human health, such as preventing cardiovascular disease or improving reproductive function. Therefore, further epidemiological studies considering various factors, such as cigarette consumption, alcohol consumption, stress index, salt intake, and genetic factors, are required to reliably elucidate the effects of dietary sodium nitrite and meat on the incidence of diseases, such as colorectal cancer.

High intakes of sodium may increase the risk of hypertension or cardiovascular diseases. According to the 2010 Korea National Health and Nutrition Survey, the average intake of sodium was 4,878 mg/day with salt, kimchi, soy sauce, fermented soybean paste and Ramyeon being the five main sources of sodium. In order to identify solutions to reduce the intake of sodium, we investigated the intake patterns and eating behaviors of Ramyeon among 347 college students (male 146, female 201) using survey questionnaires. The average age of study subjects was 23.7 years for males and 20.5 years for females. The average Body Mass Index ($kg/m^2$) was 21.9 for males and 20.1 for females. The average frequency of Ramyeon intake was 2.0 times/week. The main reason for eating Ramyeon was convenience (56%), followed by good taste (27%), low price (11%) and other reasons (9%). The criteria for choosing Ramyeon were taste (72%), convenience (14%), price (7%), nutrition (1%), and the other factors (2%). Males' average intake of Ramyeon soup (61%) was higher than that of the females (36%). The estimated intake of Ramyeon soup by survey showed a positive correlation with the measured intake of Ramyeon soup. Sodium contents of Ramyeon were measured separately for the noodles and the soup, which were 1,185 mg/serving and 1,148 mg/serving each. Therefore, the amount of sodium intake can be reduced if students eat less Ramyeon soup. Also, we observed that dietary behaviors and soup intakes of Ramyeon between the sexes were different. Appropriate nutritional education for proper eating habits may help decrease the intake of sodium.

This study surveyed the status of recognition, effort, and satisfaction of customers on a low-sodium diet in industry foodservice. For recognition related to sodium intake, 34.6% answered 'sure' for awareness of WHO's recommended daily sodium intake. Recognition of healthiness of low-sodium diet scored an average of $3.77{\pm}0.8$. The most frequent dietary effort related to low-sodium diet was 'I leave the broth of soup/stew (23.7%)', and the most common reason for not making an effort related to low-sodium diet was 'I often eat out (25.2%)'. Recognition of saltiness of foodservice meals was $2.84{\pm}0.69$, and the saltiest food was 'kimchi (30.4%)', followed by 'side dish (17.9%)', 'soup/stew (16.8%)', and 'sauce (8.3%)'. Satisfaction of low-sodium foodservice meal was $3.04{\pm}0.71$. Reasons for recognition of saltiness of foodservice meal were mostly 'appropriate' or 'prefer less salty (86%)'. In the analysis of satisfaction of low-sodium foodservice meal according to occupation, satisfaction of 'level of saltiness ($F=5.046^{**}$)' scored an average of $3.18{\pm}0.72$, with the highest satisfaction from 'professionals'. Satisfaction of 'dietary behaviors related to sodium ($F=3.534^{**}$)' scored an average of $3.95{\pm}0.59$, with the highest satisfaction from 'government employees (p<0.01)'. These study results show that despite recognition of the healthiness of a low-sodium diet, efforts toward practicing the diet were less than adequate. Further, 25% felt that foodservice meal was a blend, whereas satisfaction of low-sodium diet was only 19%. Therefore, continuous education and advertisements are necessary in order to raise awareness as well as developing more concrete methods during preparation of meals, such as using a salt meter.

The purpose of this study was to identify food sources for major minerals such as calcium (Ca), phosphorus (P), sodium (Na) and potassium (K), and to evaluate the relationship between dietary intake of these minerals and serum lipids in healthy Korean adults. A total of 132 healthy men and women completed a physical examination and dietary record and provided blood samples for lipid profile analysis. Results showed the following daily average mineral intakes: 373.4 mg of calcium, 806.0 mg of phosphorous, 3685.8 mg of sodium, and 1938.3 mg of potassium. The calcium-to-phosphorus and sodium-to-potassium ratio was about 0.5 and 2.0, respectively. The primary sources for each mineral were: vegetables (24.9%) and fishes (19.0%) for calcium, grains (31.4%) for phosphorus, seasonings (41.6%) and vegetables (27.0%) for sodium, and vegetables (30.6%) and grains (18.5%) for potassium. The correlation analysis, which has been adjusted for age, gender, total food consumption, and energy intake, showed significantly positive correlations between Ca/P and serum HDL cholesterol levels, between Na intake and the level of serum total cholesterol, and between Na/K and the level of serum cholesterol and LDL cholesterol. Our data indicates that the level of mineral consumption partially contributes to serum lipid profiles and that a diet consisting of a low Ca/P ratio and a high Na/K ratio may have negative impacts on lipid metabolism.

This study was performed to investigate factors affecting sensitivity and preference for salty tastes of Korean adult females. Sensitivity and preference for salty tastes were determined as detection threshold concentration of NaCl solution and the optimally-preferred NaCl concentration of the bean sprout soup, respectively. A self-administered questionnaire was used to obtain the information regarding general characteristics, self diagnosis of stress, health-related lifestyle practices, dietary habits and food preferences. Dietary intake using 24-hours recall and blood pressure were measured. Salty taste detection thresholds and optimally-preferred NaCl concentrations were 0.0197% and 0.357%, respectively. There was a significant positive correlation between the optimally-preferred salt concentration and age, despite no significant correlation between either sensitivity or preference for salty taste and sodium intake, which was 3,605mg/day. Those who had bread or cereal with milk as breakfast instead of a traditional Korean meal and those who preferred jjigae to soup had significantly higher NaCl preferences for bean sprout soup. Going to bed after midnight and skipping meals (${\geq}3/week$) decreased salty taste sensitivity without reaching statistical significance. Self awareness of one's own health, recent weight changes, family history of hypertension, sleep quality, getting-up time, rate of eating and other food preferences did not affect either perception. Stress level, TV watching, BMI and sodium intake did not have significant correlation to sensitivity or preference. Further research including a large number of well-controlled subjects and more accurate measurement of sodium intake should be directed to find other factors affecting salt preference and sensitivity in order to decrease Na intake and related diseases.
