The objective of this study is to provide direction in the improvement of sodium labeling in an effort to reduce consumption. We surveyed confirmation and importance of food labeling and nutrition information and we also analyzed the willingness to pay on new nutrients labeling. Consumers checked the sell-by-date, product name, method of intake, but not nutritional information. They also checked for calories and carbohydrates but they were not interested in sodium, sugar, and trans fat which are health hazard nutrients. It is necessary to improve nutrition labeling, because consumers are experiencing difficulties in obtaining sodium information under the nutrition labeling system. Consumers will pay about 0.66% more if new sodium labeling is introduced. In conclusion, food labeling system can be improved by smooth and efficient access of information. for health-hazard nutritional components, such as sodium, it is important to introduce policies that reduce their intake. This can be done by providing consumers with clear and concise information. The social costs of high sodium intake could be reduced, hence improving the national health.

BACKGROUND/OBJECTIVES: The aims of the present study are: 1) to quantify sodium consumption of patients with unstable or uncontrolled hypertension, 2) to investigate if reduced sodium intake can lower BP in these patients, and 3), to assess the acceptability and feasibility of this approach. SUBJECTS/METHODS: This study included 25 adults (age: 50+ years) with frequently elevated BP or patients with uncontrolled, uncomplicated hypertension despite drug treatment in a general practice setting. BP and salt intake (24h urinary excretion and food records) were measured at baseline and after a sodium reduced diet. RESULTS: Mean (${\pm}SD$) systolic (SBP) over diastolic (DBP) blood pressure (mmHg) at baseline was $150.7({\pm}9.5)$/$84.149({\pm}5.6)$. Mean urinary sodium excretion was 146 mmol/24h. A reduction of 28 mmol sodium excretion decreased SBP/DBP to $135.5({\pm}13.0)$/$82.5({\pm}12.8)$ (P < 0.001). After one month of no dietary advice, only in 48%, SBP was still ${\leq}140mmHg$. CONCLUSION: Assessment of sodium intake using food records, 24h urine collections and probing questions to identify use of sodium containing supplements or drugs are essential for tailored advice targeted at sodium intake reduction. The results of the present study indicate that reduced sodium intake can lower BP after 4 weeks in unstable or uncontrolled hypertensive patients.
This study was conducted to investigate the effect of sodium reduction education program of a public health center on the blood pressure, blood biochemical profile and sodium intake of hypertensive adults. The program continued for 16 weeks with an 8-week nutrition education and an 8-week follow-up to forty two subjects, 6 males and 36 females aged 46 to 80 years. Subjects received nutrition education including lectures, activities, cooking classes and nutrition counseling. Physical fitness, management of stress, and nutrition counseling were provided during the follow-up. The program was evaluated three times, before and after the nutrition education, and after the follow-up. Systolic blood pressure (p < 0.0001) and diastolic blood pressure (p < 0.001) were decreased after completion of the program. Body weight (p < 0.005), percent body fat (p < 0.005) and body mass index (p < 0.001) were decreased, too. There were no significant differences in blood glucose, HDL-cholesterol and triglycerides, while elevated levels of total cholesterol (p < 0.001) and LDL-cholesterol (p < 0.001) appeared after the program completion. Decreased intakes of vitamin A (p < 0.05), ${\beta}$-carotene (p < 0.001) and sodium (p < 0.001) were observed. Consumption frequency of noodles, soups, stews, kimchi, fishes/shellfish, seasoned vegetables, and salted seafoods/pickles (p < 0.05~p < 0.001) were decreased, while that of all food groups were not changed during the follow-up. Total score of nutrition knowledge related to sodium intake and hypertension (p < 0.001), and that of dietary behavior associated with high sodium intakes were changed positively (p < 0.001) only during the nutrition education. This sodium reduction education program, including the follow-up study showed positive effects on the blood pressure, sodium intake, nutrition knowledge and dietary behavior of hypertensive adults.
We attempted to define the sources of sodium intake for the Korean population at prepared dish level to provide a basis for developing sustainable nutrition policies and feasible programs for sodium intake reduction. Dietary intake data from 2008 and 2009 Korea National Health and Nutrition Examination Survey was used in the analysis for sodium intake sources. Sodium intake from individual dish consumed by each subject was calculated and used in delineating major sodium sources at dish and dish group level for sub-populations of different sex and age. Also, sodium intake was compared between eaters and non-eaters of some specific dish groups with considerable contribution to total sodium intake. The number of subjects included in the analysis was 18,022 and mean sodium intake was 4,600 mg/capita/day. Major sources of sodium intake at dish group level were in the following order: kimchi (1125 mg, 24.5%), noodles (572 mg, 12.4%), soups (488 mg, 10.6%), stews (399 mg, 8.7%), and cooked rice (284 mg, 6.2%). The magnitude of contribution to total sodium intake by soups and stews was different by age group. Sodium intake difference between eaters and non-eaters was much larger for kimchi group (2,343 mg for male, 1,452 mg for female) than for soups or stews. Interaction between consumption of aforementioned specific dish groups and age was highly significant (p < 0.0005) for both sexes. This study revealed an importance of having not only the control over sodium content of foods/dishes, but also the customized approach for different groups of population to accomplish an appreciable reduction in sodium intake.
This study assesses the sodium intake of adults by 24-hour urine analysis, dietary records review and a food intake questionnaire. Subjects were 236 adult female in Daegu. The results are summarized as follows: Sodium intake as indicated by the 24-hour urine analysis was $5,805.4\;{\pm}\;3836.8\;mg$. This was significantly higher than intake indicated by dietary records ($4415.4\;{\pm}\;1935.1\;mg$) and the dish frequency questionnaire (DFQ 55) ($4293.5\;{\pm}\;1526.5\;mg$). The results of the 24-hour urine analysis and DFQ 55 showed that sodium intake was higher for the 65-to-74-year-old age group than for other age groups (p < 0.05, p < 0.05). Review of dietary records to examine typical sodium intake by food groups showed that 53.7% of the sodium consumed by subjects in all age groups came from seasonings and spices ($2399.0\;{\pm}\;1526.5\;mg$). The analysis of sodium intake by food groups using DFQ 55 showed 34.2% of their sodium came from consumption of kimchi (p < 0.001) and kimch, soup, stew and fish jorim accounted for 57.8% of total sodium intake. The results indicate positive correlation between age and sodium intake, as shown by the 24-hour urine analysis and food intake questionnaire (p < 0.05). Therefore, these results would be valuable as basic data for planning nutrition education for sodium intake reduction.
This study was conducted to provide guideline data for future instructional materials and practice guidelines on reforming the dietary life of military personnel in terms of lowering sodium intake. A total of 264 persons were surveyed to obtain basic data on sodium intake and understanding of sodium. The study also examined the practice that is carried forward in this endeavor. The subjects liked 'kimchi' and 'rice with topping', and these could be the reason for higher salt intake. Career soldiers scored higher in terms of nutrition knowledge than enlisted soldiers (p<0.01). Nutrition education concerning sodium intake was statistically insignificant between the two, whereas career soldiers showed a higher experience rate at these nutrition educational events. Career soldiers also had with higher sodium intake than enlisted soldiers, and this difference was statistically significant (p<0.01). In terms of practice, officers were more likely to experience difficulty in putting the theory of less sodium into practice than their enlisted soldiers counterparts (p<0.05), and the main reason behind this difficulty was that they did not feel the need to lower their sodium intake. Soldiers should be well educated about sodium and healthy diet during their service. Education should focus on lowering sodium intake and changing their attitudes and awareness of this issue in order to elicit behavioral changes.

BACKGROUND/OBJECTIVES: This study was conducted to evaluate the feasibility of a sodium reduction program at local restaurants through nutrition education and examination of the health of restaurant owners and cooks.SUBJECTS/METHODS: The study was a single-arm pilot intervention using a pre-post design in one business district with densely populated restaurants in Seoul, South Korea. The intervention focused on improving nutrition behaviors and psychosocial factors through education, health examination, and counseling of restaurant personnel. Forty-eight restaurant owners and cooks completed the baseline survey and participated in the intervention. Forty participants completed the post-intervention survey. RESULTS: The overweight and obesity prevalences were 25.6% and 39.5%, respectively, and 74.4% of participants had elevated blood pressure. After health examination, counseling, and nutrition education, several nutrition behaviors related to sodium intake showed improvement. In addition, those who consumed less salt in their baseline diet (measured with urine dipsticks) were more likely to agree that providing healthy foods to their customers is necessary. This study demonstrated the potential to reduce the sodium contents of restaurant foods by improving restaurant owners' and cooks' psychological factors and their own health behaviors. CONCLUSIONS: This small pilot study demonstrated that working with restaurant owners and cooks to improve their own health and sodium intake may have an effect on participation in restaurant-based sodium reduction initiatives. Future intervention studies with a larger sample size and comparison group can focus on improving the health and perceptions of restaurant personnel in order to increase the feasibility and efficacy of restaurant-based sodium reduction programs and policies.

Given that fermented foods, such as kimchi and doenjang, are main food sources for high sodium intake in Korea, there have been needs to develop sodium-reduced kimchi and doenjang with the proper quality. However, small and medium sized business could not actively develop the sodium-reduced products due to lack of techniques and information as well as economical reasons. The most important aspects is to address food safety issues including microbial contaminations in sodium-reduced foods. Hurdle Technology, physical, biological, chemical control technique, would have to be preferentially considered to increase the hygiene safety standards in entire processing steps including raw materials, process water, manufacturing environments, and so on. Once the food hygiene level is stable, the next challenges are to improve the taste of the sodium reduced-products as well as to packaging and storage technologies. The development of a variety of sodium-reduced fermented foods would result in significant mitigation of sodium intake by Korean. This report provides the directions to develop sodium-reduced kimchi, doenjang or pickled food products for small and medium sized business, based on the technical consulting results of sodium reduction project supported by Ministry of Food and Drug Safety in 2015.
BACKGROUND/OBJECTIVES: Targeting consumers who consume lunches at their worksite cafeterias would be a valuable approach to reduce sodium intake in South Korea. To assess the relationships between socio-demographic factors, consumer satisfaction, attitudes, barriers and the frequency of sodium-reduced meal intake. SUBJECTS/METHODS: We implemented a cross-sectional research, analyzing data from 738 consumers aged 18 years or older (327 males and 411 females) at 17 worksite cafeterias in South Korea. We used the ordinary least squares regression analysis to determine the factors related to overall satisfaction with sodium-reduced meal. General linear models with LSD tests were employed to examine the variables that differed by the frequency of sodium-reduced meal intake. RESULTS: Most subjects always or usually consumed the sodium-reduced meal (49%), followed by sometimes (34%) and rarely or never (18%). Diverse menus, taste and belief in the helpfulness of the sodium-reduced meal significantly increased overall satisfaction with the sodium-reduced diet (P < 0.05). We found importance of needs in the following order: 1) 'menu diversity' (4.01 points), 2) 'active promotion' (3.97 points), 3) 'display of nutrition labels in a visible location' (3.96 points), 4) 'improvement of taste' (3.88 points), and 5) 'education of sodium-reduction self-care behaviors' (3.82 points). CONCLUSION: Dietitians could lead consumers to choose sodium-reduced meals by improving their taste and providing diverse menus for the sodium-reduced meals at worksite cafeterias.
Sodium chloride (NaCl) is a very important as one of major food ingredients in food industries. Recently, as the potential risk of adult diseases such as hypertension by overingestion of sodium, health authorities of many countries are executing policies for the reduction of sodium to suppress the overingestion of sodium by intake of NaCl. As general ways, the replacement of NaCl with either alternative salts, such as solar salts and minerals, for examples calcium, magnesium, potassium, lactic acid, and so on, and the addition of flavor enhancers were used to reduce the contents of sodium in foods. Recently, controls of particle size of sodium chloride or release point are emerging as new salt-manufacturing technologies for the sodium reduction. Upon reducing NaCl in foods it is important to develop practically adaptable technologies on the basis of the consideration of the unique functions of NaCl in foods, in particular effects on rheological characters, function as a humectant, shorten shelf life time, and so on.
