Excessive sodium intake leading to hypertension, stroke, and stomach cancer is mainly caused by excess use of salt in cooking. This study was performed to estimate the salt content in school meals and to compare differences in perceptions related to sodium intake between students and staffs working for school meal service. We collected 382 dishes for food from 24 schools (9 elementary, 7 middle, 8 high schools) in Gyeonggi-do and salt content was calculated from salinity and weight of individual food. The average salt content from elementary, middle, and high school meals were 2.44 g, 3.96 g, and 5.87 g, respectively. The amount of salt provided from the school lunch alone was over 80% of the recommended daily salt intake by WHO. Noodles, stews, sauces, and soups were major sources of salt intake at dish group level, while the most salty dishes were sauces, kimchies, and stir-fried foods. Dietary knowledge and attitude related to sodium intake and consumption frequency of the salty dishes were surveyed with questionnaire in 798 students and 256 staffs working for school meal service. Compared with the staffs, the students perceived school meals salty and the proportions of students who thought school meals were salty increased with going up from elementary to high schools (P < 0.001). Among the students, middle and high school students showed significant propensity for the preference to one-dish meal, processed foods, eating much broth and dipping sauce or seasoning compared with the elementary students, although they had higher nutrition knowledge scores. These results proposed that monitoring salt content of school meals and consideration on the contents and education methods in school are needed to lower sodium intake.

본 연구에서는 20대 초반 한국 여성의 짠맛 역치 및 선호도를 측정하여 음식섭취빈도법을 통해 추정한 나트륨 섭취량과의 연관성을 분석하고, 자기 평가 짠맛 선호도와 관련되어 있는 나트륨 섭취 관련 식행동과 나트륨 섭취 기여 음식을 조사하였다. 자기 평가 짠맛 선호도는 음식섭취빈도법을 이용하여 추정한 나트륨 섭취량과 유의한 양의 상관관계에 있었으며, 나트륨 증가 식행동과 양의 상관관계에 있었고, 나트륨 감소 식행동과 음의 상관관계에 있었다. 나트륨 섭취와 관련된 식행동 중에는 식탁에서 소금과 양념간장의 사용, 외식과 배달음식의 빈도, 국, 찌개, 국수류의 국물 섭취, 레토르트나 가공 식품의 이용, 생채소의 섭취, 싱거운 맛에 대한 수용태도 등의 항목이 자기 평가 짠맛 선호도와 유의한 관련성이 있었으며 나트륨 섭취 기여음식 중에는 라면, 순두부찌개, 총각김치 및 김치를 이용한 음식 등이 자기 평가 짠맛 선호도와 유의하게 관련되어 있어, 짠맛 선호도가 이들 식행동 및 음식을 통해 높은 나트륨 섭취와 관련되어 있는 것으로 생각된다. 예상과는 달리 짠맛 검출 및 인식 역치는 자기 평가 짠맛 선호도, 나트륨 섭취량, 나트륨 증가 및 감소 식행동과 유의한 상관관계를 보이지 않아 식품체계가 아닌 염화나트륨 수용액을 이용한 짠맛 역치보다는 자기 평가된 짠맛 선호도가 개인의 평상시 나트륨 섭취량을 간접적으로 평가할 수 있는 더 좋은 지표로서 생각된다. 결론적으로, 자기 평가 짠맛 선호도는 나트륨 섭취와 관련된 식행동과의 연관성으로 인하여 평상시 나트륨 섭취 정도를 잘 반영하는 것으로 나타났으며, 개인의 나트륨 섭취 수준을 평가하는 간단하고 효과적인 도구로서 활용될 수 있을 것이다.

This study was to develop and evaluate a nutrition education program to reduce dietary sodium. The school children (218 boys, 226 girls), from 8 elementary schools in the city of Daegu, Korea, were involved in this study. This research was based on the data from two groups of elementary school children, the "education" group (n = 240), and "no-education" group (n = 204). Educational media and programs were developed to educate the education group for four weeks and were presented on the web (www.saltdown.com). After education, the preference for a non-salty taste in the education group increased 10%, compared with those who preferred a non-salty taste before education. There was a significant change away from a preference for a salty taste and a rise in the mean score for nutrition knowledge and dietary attitude in the education group compared to the no-education group (p < 0.05). This study indicates that school children can reduce their dependency on preference for a salty taste and change their high-salt dietary behavior after the education.

The purpose of the study was to investigate the influence of salt (NaCl) recognition threshold and pleasant salt concentrations of Korean rural elderly subjects on preference of salty food as well as food group consumption patterns. The subjects were 213 elderly people (male 71 and female 142) over 65 and under 90 yr of age from Sunchang area. The higher values were found with male subjects in the areas of basic taste recognition threshold and pleasant concentration level of salt. The taste sensitivity scores of male subjects did not decrease with the increasing age, but female subjects exhibited a significant decrease with the age. The major determinant factor of salt preference of the elderly subjects in this study appeared to be personal pleasant concentration of salt rather than salt recognition threshold level and this trend was more evident in males than in females. The subject group of lower salt pleasant concentration i.e. consuming less salt showed the higher number of fruit and fruit juice intakes per week, and higher MNA (define this) scores were implying that they display more desirable nutritional status. Therefore, nutritional education focused on not only a variety of food consumption but also lowering pleasant salt concentration levels is advised to improve the quality of nutrition in the elderly.

This study was performed to investigate the effects of taste preference on dietary behavior and nutrient intake. The subjects were 191 female collegians in the Gyeonggi and Gangwon areas. Data were collected using anthropometric measurements, 24-hour recall, and self-administered questionnaires. The respondents were classified into sub-groups according to taste preference: sweet taste (liked and disliked group), salty taste (liked and disliked group), sour taste (liked and disliked group), hot taste (liked and disliked group), and bitter taste (liked and disliked group). The results of this study are as follows: subjects liked, in order of taste preference, hot>sweet>sour>salty>bitter tastes. There were no significant differences in height, weight, and BMI among the groups. The sweet-taste-liked group, tended to prefer Chinese food and fast foods for eating out over the sweet-taste-disliked group (p<0.05). Subjects in the salty-taste-liked group ate faster (p<0.05) and more than those in the salty-taste-disliked group (p<0.05). They also consumed more animal fat and meat (p<0.05) than their counterparts. Compared with the sour-taste-disliked group, subjects in the sour-taste-liked group tended to select Korean food or Japanese-style food for eating out, and fruits for a snack (p<0.05). The meal size of the hot-taste-liked group tended to be more regular (p<0.05) than that in the hottaste-disliked group. Overall, there were distinct differences in dietary behavior and food choices according to taste preference. Taste preference should be considered for dietary consulting and nutritional education.

소금의 과량 섭취가 건강에 유해한 영향을 미칠 수 있어 이를 해결하기 위한 다양한 연구가 진행되고 있다. 최근 우리나라의 전통 발효 식품인 간장, 액젓 등이 짠맛을 증진한다는 보고가 있어 이에 대한 연구가 활발히 이루어지고 있다. 본 연구에서는 어간장과 액젓의 주요 재료로 사용되는 멸치를 효소 가수분해한 eHAP의 짠맛 증진 효과에 대해 살펴보았다. 동일한 소금농도의 용액에 eHAP의 첨가량을 달리하였을 때 첨가량이 증가할수록 짠맛 증진효과도 증가하여, 50 mmol/L의 용액에 2%의 eHAP를 첨가하였을 경우 $67.79{\pm}6.35%$의 짠맛 강도를 인지하였으며, 용액의 소금농도가 높을수록 eHAP의 첨가에 따른 짠맛 증진효과가 더 크게 나타났다. 이러한 짠맛 증진 효과는 멸치 단백질 가수분해물에 다량 함유하고 있는 $\small{L}$-lysine과 $\small{L}$-arginine과 감칠맛을 나타내는 glutamic acid와 aspartic acid에 상호작용에 의한 것으로 보인다. 0.1%에서 2%까지 eHAP의 첨가량을 달리하였을 경우 최소 0.37%에서 최대 35.58%의 짠맛 증진 효과를 나타내어 멸치단백질 효소가수분해물이 염미 증진제로서 향후 활용 가능성이 있는 것으로 판단된다.

The purpose of this research was to evaluate the correlation between obesity, threshold of salty taste, optimal saltiness and blood pressure in middle school students in a fishing village. The subjects were 115 boys and 103 girls in middle school in a fishing village. The BMI index and systolic and diastolic blood pressures of subjects were measured, and the subjects were divided into a normal and obese group according to their BMI. The threshold of salty taste and salt preference for a semisolid dish (steamed egg dish), liquid dish (bean sprout soup), and a solid dish (raw radish salad), were estimated by sensory evaluation. Calorie intake was measured using the weighing plate method. The boys in the obese group showed significantly higher systolic and diastolic blood pressures than those in the normal, but girls did not. Furthermore, calorie intakes of the boys in the obese group were significantly higher than those in the normal group, but this was not shown in girls. On the threshold of salty taste, both boys and girls in the obese group needed higher concentration of salt than those in the normal group. The threshold of salty taste were significantly positively correlated with systolic pressure and diastolic pressure in boys. Regarding the salt preference in the steamed egg dish, bean-sprout soup, and raw radish salad, both boys and girls in the obese group preferred higher concentrations. The higher concentration they preferred, the higher the systolic and diastolic pressures were in boys, but only systolic blood pressure was higher in girls. From these results, it is evident that a nutritional education program is needed in school to help restricting middle school students salt consumption and decreasing obesity to prevent hypertension.

The purpose of this study was to evaluate the effectiveness of nutrition education and counseling on the salty taste assessment, nutrition knowledge and dietary attitude of 21 hemodialysis patients. Five times of the nutrition education and three times of nutrition counseling were performed for a period of 5 months. Biochemical analysis revealed that creatinine was significantly high (p < 0.001), blood urea nitrogen and serum albumin were significantly low (p < 0.05, p < 0.01) and Na, K, Cl, K, P and uric acid were not significantly different. The distribution rate of unsalty taste preference were significantly high and the distribution rate of salty taste preference were significantly low after nutrition education and counseling (p < 0.001). Nutrition knowledge significantly improved following 5th month of education and counseling (p < 0.01). Particularly, the scores for questions related to sodium were improved. The dietary attitude was significantly improved during the counseling period (p < 0.05). There were improvements in responses to 'use food exchange list on diet' and 'habitually add salt or soy sauce before the meal'. According to these results, salty taste assessment, nutrition knowledge and dietary attitude were significantly improved by the hemodialysis diet therapy practices of hemodialysis patients. Therefore, we conclude that there was a need for low-salt diet education and nutrition counseling to help them recognize the taste of low-salt foods and strive towards a preference for less salty tasting foods and the consumption of a low-salt diet.

This study investigated the preference and intake frequency of a list of 15 commonly available high sodium Malaysian foods/dishes, dis cretionary salt use, and their possible association with demographics, blood pressures and anthropometric measurements among 300 Malaysian university students (114 males, 186 females; 259 ethnic Chinese, 41 Indians; 220 lean, 80 overweight). French fries and instant soup noodle were found to be the most preferred and most frequently consumed salty food, respectively, while salted fish was least preferred and least frequently consumed. Males had a significantly higher intake frequency of at least 6 of the salty foods, but the preference of most salty foods was not significantly different between genders. Ethnic Chinese significantly preferred more and took more frequently traditional and conventional Malaysian foods like asam laksa (a Malaysian salty-sour-spicy noodle in fish stock), salted biscuits and salted vegetable, while Indians have more affinity and frequency towards eating salty Western foods. Body Mass Index was significantly negatively correlated with the intake frequency of canned/packet soup and salted fish while waist circumference was significantly positively correlated with the preference of instant noodle. Also, an increased preference of potato chips and intake frequency of salted biscuits seemed to lead to a decreased WHR. Other than these, all the other overweight/obesity indicators did not seem to fully correlate with the salty food preference and intake frequency. Nevertheless, the preference and intake frequency of asam laksa seemed to be significant negative predictors for blood pressures. Finally, increased preference and intake frequency of high sodium shrimp paste (belacan)-based foods like asam laksa and belacan fried rice seemed to discourage discretionary salt use. In conclusion, the preference and intake frequency of the high sodium belacan-based dish asam laksa seems to be a good predictor for ethnic difference, discretionary salt use and blood pressures.
