This study was conducted as a comparative analysis, using the SPSS 17.0 program for a survey conducted from March to July 2013, on the level of perception and preference factors of Koreans and Americans residing in Virginia, USA(89 male and female adults of 20 years of age or above). For the information on the degree of obesity, a survey was used and the subjects provided with their heights and weights. The researcher used this data to calculated their BMI and distinguished the degrees of obesity. For the BMI, the obesity diagnosis of Korean Society for the Study of Obesity was used for Koreans, and the WHO's obesity diagnosis on adults were employed for Americans. First, regarding the Korean participants, the level of obesity appeared in the order of normal (79.6%), overweight (14.3%), and underweight (6.1%). Also, the level of perceptions of their health conditions appeared in the order of average (51.7%) and good (34.7%). No one perceived their health to be in poor condition. Meanwhile, for the American participants, the order was as follows: overweight at about 45%, normal weight at about 35%, obesity at about 12.5%, and underweight at about 7.5%. In terms of the level of perception of health during ordinary times, about 55% of the American participants answered that they are in good health. Therefore, the Americans were found to perceive their health to be in relatively better condition than the Koreans residing in the USA. Also, concerning the level of interest in health while eating food at ordinary times, the American participants were discovered to be more interested (about 62.5%) than the Korean participants. The research on their preference for salty taste was conducted as a survey, and the subjects were asked to choose an item according to their subjective feeling. Regarding the preference for salty taste, both Koreans and Americans residing in the USA responded as moderate. However, a higher proportion of Americans than Koreans responded to favor salty taste. Concerning the reason for their preference for salty taste, Koreans responded with various reasons whereas Americans mostly responded that it is because they eat salty food frequently. For any changes in dietary behavior related to eating salty food, both Korean and American respondents thought that the amount of their daily intake of salt is appropriate and that they consider taste as most important in selecting a snack. Based on the above data, the results of this research indicate a need for actual improvement in the diet with regard to salty food along with diverse policies for promoting life with a low salt diet in future.

This study investigated the effect of taste preference(sweet, sour, salty, hot) on anthropometric measurements and nutrient intakes of 256 primary school children in Kwangju. There was no significant difference in the anthropometric measurements according to the sweet taste preference. Height, weight, triceps, abdomen, and chest circumferences of the group preferring a sour taste, however, were significantly lower than those of the other groups. The height of the group preferring a salty taste was significantly shorter than that of the other groups and there was a tendency toward high systolic blood pressure and diastolic blood pressure. The waist circumference of the group not preferring the hot taste was larger than those of the other groups. There was no significant difference in the energy intake according to the sweet taste preference. The protein intake of the group preferring a sweet taste as significantly lower than that of the other groups. The fiber intake of the group preferring a sour taste was significantly higher than that of the other groups. There were no significant differences in the nutrient intakes according to the salty taste preference. The energy intake of the group preferring a hot taste was lower than that of the other groups. The results show that children's taste preferences influence anthropometric measurements and nutrient intakes. These results suggest that children's eating behaviors are in needs of correction. The findings of this study should be applied to nutrition education to ensure better physical fitness of children.

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.

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 was conducted to verify the relation between relation between vegetarian diet and the serum lipid levels, blood sugar and blood pressure from October 1996 to February 1997. The vegetarians subjects were 245 Buddhist nuns (age:23～79 yrs) and control subjects consisted of 235 healthy female adults (age: 23～70 yrs) selected from the teachers, the nurses and the housekeepers living in Chinju Gyeongsang Nam-do. The contents included anthropometric measurement, questionnaires about eating behavior score and preference for taste and biochemical characteristics of the blood. The results were summarized as follows. The average duration of vegetarian diet of the vegetarians was 13.1 years. Vegetarians prefer to a pepper, a sweet and a acidic in the right order but that non-vegetarians prefer to a sweet, a acidic and pepper in the right order. Both groups of less than a decade and more than two decade of vegetarian diet prefer to a pepper, sweet, a acidic, a bitter, a salty and a lily, and a 10～20 yr group with vegetarian diet was fond of a pepper, a bitter, a acidic, a sweet, and a oily, in the right order. This seems to be ascribable to a difference in the health knowledge and interest. Vegetarians and non-vegetarians who said that they were fond of salty were 38.8% and 52.8%, medium was 33.9% and 33.6%, and not salty was 27.3% and 13.6%. Eating behavior score of vegetarians and non-vegetarians were 25.1 and 23.1 respectively. Eating behavior scores of vegetarians were significantly higher than those of non-vegetarians (p<0.05). Eating behavior scores of the group with more than a decade of vegetarian diet were significantly higher than those of the group with less than a decade of vegetarian diet. Levels of serum total-cholesterol, LDL-cholesterol, and AI of the salty group were significantly higher (p<0.05) than those of not salty group. Levels of serum triglyceride, HDL-cholesterol, blood sugar had no significant relation with preference of salty. Blood pressure was not related with preference of salty, but that of those who prefer a salty tended to be high. This study also reveals that the preference of a salty was significant influence on serum total-cholesterol, LDL-cholesterol, and AI, but the vegetarians did not prefer salty and have a good eating behavior. Consequently, vegetarian diet can be considerably effective in reducing the level of the risk factors of cardiovascular disease.

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.

He purpose of this study was to provide basic data for improvement commercial kimchi quality. To examine the consciousness of commercial kimchi, college students residing in the Jeonnam area were selected and asked to questionnaires. Commercial kimchi samples used included a total of 7 kinds which were fermented for 2 week at $4^{\circ}C$. A sensory characteristics included 10 items with a 5-score scale: color, savory taste, carbonated taste, sour taste, hot taste, salty taste, bitter taste, off-flavor, texture, and overall preference. 76% of the whole student liked kimchi, especially well-fermented kimchi(43.2%) and kimchi with fermented fish(48.6%). Participants liked savory(21.6%), hot(17.1%), and crispy(14.4%) taste. Their most favorite kimchi was the whole cabbage kimchi(26.1%), wild lettuce kimchi(0.9%) and watery kimchi made of sliced radishes(1.8%) were low in preference. 56.8% of participants had no experience in making kimchi. They mainly bought commercial kimchi in grocery stores(37.8%) or shopping malls(29.7%). They pointed out the addition of artificial sweeter(35.1%), insanitation, and discredit of kimchi materials(21.6%) as problems of commercial kimchi. The sensory characteristics of commercial fresh kimchi was significantly different in color($2.6{\sim}4.1$), and hot($2.3{\sim}3.8$), and salty($2.6{\sim}3.5$) with p<0.001. The sensory characteristics of $4^{\circ}C$-fermented commercial kimchi for 2 week was significantly different in color($2.7{\sim}3.9$), and salty($2.1{\sim}4.0$) with p<0.001. It was found that color, and hot, and salty taste had the greatest effect on the overall preference in non-fermented kimchi, and color and salty taste, in 2 week fermented kimchi

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 this study was to compare regional differences in salty taste assessments, nutrition knowledge, dietary attitudes and dietary behaviors associated with high-salt diets in four national regions in Korea (Region 1: Seoul, Sokcho, Region 2: Buyeo, Jecheon, Gong Ju, Region 3: Daegu, Gyeongsan, Region 4: Jeon Ju). Subjects were 860 persons who participated in sodium reduction campaign. The result of the salty taste assessment by region was not significantly different. The nutrition knowledge score of subjects in Region 1 was the highest. Dietary attitude scores that showed preference for high-salt diets of Region 2 and Region 4 subjects were higher than those of Regions 1 and 3 subjects (p < 0.001). Dietary behavior scores were not significantly different among regions. The correlation between sodium intake and salty taste assessment was significant (p < 0.01). Older subjects who had high blood pressure levels and lower nutrition knowledge were more likely to have high sodium intakes. Even though the salty taste assessment and dietary behavior scores by region were not significantly different, the salty taste assessment scores had a significant negative correlation with nutrition knowledge and had a significant positive correlation with dietary attitude and dietary behavior in terms of preference for high-salt diets. Therefore, nationwide education regarding salt intake reduction and health and a campaign to encourage favorable attitudes and behavioral changes regarding consumption of a no-salt / low-salt diet is needed.

College women of 136 in Kyoung-Buk province were studied in order to investigate the quantity of Na intake and preference for salty taste in diet. Also the relation of family's history on hypertention and their Na intake and preference for salty taste were studied. Three type of meal with 9g NaCl, 12g NaCl, 15g NaCl and four type of beef soup with 0.2% NaCl, 0.4% NaCl, 0.6% NaCl, 0.8% NaCl were prepared. The computating value of Na according to the food composition table and the amount of Na by chemical analysis were almost equal. The meal with 12g NaCl was favored 58.8% of the subjects, hence the amount of Na intake per day was thought 13g roughly.50.7% of subjects prefered of beef soup with 0.6% NaCl and those who thought that they eat salty had tendency to like food with high amount of salt. 73 subjects(53.7%) had family's history on hypertention, then 38 subjects (52.9%) among them liked beef soup with 0.4% NaCl 63 subjects(46.3%) didn't have family's history on hypertention, then 44 subjects among thorn liked beef soup with 0.6% NaCl. The subjects with family's history on hypertention liked more salty taste than the subjects with no family.s history on hypertention.
