Objectives: The aim of this study was to investigate the effects of DASH diet and law salt diet health education program on the blood pressure and the diet habit in the prehypertension group in Korea. Methods: The participants in this study were 141 people with prehypertension who were seen at a public health center. Data collection was done from March 11 to November 11, 2005 using interview with questionnaires. The participants took part in the diet health education program for 8 weeks. In order to evaluate the effectiveness of health education program, the variables of the diet such as hypertension, law salt diet and DASH diet were measured before and after the health education. The blood pressure was measured three times during the education. The collected data were analyzed with paired t-test and repeated ANOVA using SPSS 12.0 for Windows. Results: The diet habit variables after the education showed that their diet habit tend to the low salt diet and the DASH diet. The participants improved in their knowledge of hypertension and law salt diet, and they improved in the behavioral level of law salt diet and DASH diet after the health education for 8 weeks. Systolic and diastolic pressure were significantly decreased in prehypertension group after 8 weeks [10mmHg/6mmHg(p<0.001)]. Conclusion: These result suggest that the improvement in the level of behavior might be related with the change in blood pressure among the people having prehypertension in Korea.

We compared three nations' diets on Year 2000 Korean, American and Mediterranean in the aspect of contribution of each to the development of cardiovascular diseases. We searched all the available evidences published. Korea has a very low incidence of cardiovascular diseses compared to the other countries even though they are increasing recently. In addition to many risk factors to these defenerative diseases such as diabetes millitus, hypertension, smoking, hyperlipidemia, sedentary lifestyle, etc., dietary factors are also contributing a lot to their development. High calorie, trans fatty acids, cholesterol, saturated fatty acids, alcohol, salt intakes are examples. Korean diet has superiority of low calorie, low fat, good fat proportion, high omega-3 fatty acids, vegetables, beans, and garlic and onions These are believed to contribute to low incidence of cardiovascular diseases in Korea. Korean diets was also found to have some issues for improvement such as high salt, low calcium, and higher use of barbequed meats. We concluded Korean people stay better off with Korean diet with some modifications.

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.

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 is to find out how the 4 types of calcium salt such as calcium carbonate, calcium phosphate, calcium lactate and calcium citrate in soy protein diet, the vegetable protein source, affect the calcium utilization in the body. To do so, calcium, phosphate and creatinine concentration and ALP activity in blood as well as the content of calcium and ash, the length, weight strength, and the calcium utilization in the bone were measured. Four groups of Sprague-Dawley male rats with the weight of around 180g were fed for 3 weeks with the experimental diet. Each group was fed with the isolated soy protein containing 14% of the diet and the above mentioned 4 types of calcium salt as the calcium source. The results are as follows; 1. There were no differences of the feed intake, weight gain, and feed efficiency among groups. 2. ALP activity in blood was sinificantly high in calcium lactate group(P<0.05), but there were no differences of concentration of calcium, phosphates, and creatinine in blood among groups. 3. The weight, calcium content, calcium ratio in ash and the strength of bone were low when calcium lactate was provided(P<0.05). 4. The content of calcium in the liver was high in calcium lactate group and calcium citrate group(P<.0.05). 5. The exceretion of feces was low in calcium lactate group(P<0.05) and the excretion of urine was also relatively low. In addition, the ratio of absorption and the retention of calcium were high(P<0.05). In summary, out of four types of calcium salt such as calcium carbontate, calcium phosphate, calcium lactate and calcium citrate when calcium lactate was provided the ALP activity in blood was high and the weight, calcium content, calcium ratio in ash and the strength of bone were low. In calcium utilization, the ratio of absorption and retention of calcium were high, however it has lower effect than 3 other calcium types in improving weight, the content of calcium and the strength of bone.

Sodium chloride plays an important role as the main condiment at daily meal. It is well known that humans require sodium chloride as an essential nutrient to keep the homeostasis of electrolytes. The amounts of salt intake may be a reflection of geography, culture and food habit rather than necessity. Lee has reported (1962) that Koreans ingest high amounts of sodium chloride in their meals, with an intake of excess carbohydrate (80-90% of total Calories) and low protein in their diet. This includes large amounts of rice, Kimchi and other fermented soybean products common in the Korean diet. This investigation was designed to study the dietary relations of sodium chloride to other nutrients in the Korean diet. Twenty four albino male rats, weighing from 290-300g, were divided into four dietary groups according to the amounts of carbohydrate, protein and fat in the basal diet. Each diet contained a rice powder as a carbohydrate source. Diet I was a control diet, Diet II, low protein, Diet III, low protein and low fat diet and Diet IV, low fat diet. All rats were provided with 3% sodium chloride solution. Diet and salt solution were given ad libitum. The experiment was carried out for 9 weeks during which time the body weight, the food intake, and 3% sodium chloride solution consumption were determined. At the 9th week, the urine was collected the blood sample from the artery of each rat for the analysis of sodium and potassium and other chemical studies. The rats were sacrificed and the kidney, adrenal, liver and spleen were measured, and observed changes of the pathological tissue in the kidney and adrenal. The results were summarized as follows: 1) The growth rate was higher in Diet I than in the other experimental diets (II, III and IV) after 4 weeks. There was no significant difference found between the experimental Diets II, III and IV. 2) The daily food intake was greater in the experimental diets II, III and IV than in the control diet. However, there was no difference among the high carbohydrate diets Diet II, III and IV. 3) The daily water (3% sodium chloride solution) intake was also greater in the Diets II, III and IV, than in the control diet. However, there was no difference between Diets II, III and IV. 4) The concentration of sodium and potassium in the blood were within the normal range in all diets. 5) The amount of sodium chloride in the urine was significantly greater in Diets II, III and IV than in the control diet. Diets II, III, IV had a larger amount of sodium solution consumption. 6) Observation of pathological tissue in the experimental diets found a cell proliferation in the glomerlulus of the kidney, while such change was not found in the control diet.

For the purpose of study on optimal gustation of salt 108 patients with hypertension(61 cases of male, 47 cases of female) were studied. And also 48 patients with non-hypertensive heart diseases and pulmonary diseases (20 cases of male, 28 cases of female ) and apparently healthy subjects (107 cases of male, 20 cases of female) were studied as control group. By adding salt into 3% rice boiled powder solution the 0.1%, 0.25% 0.5%, 0.75% and 1 % salt solutions were prepared respectively. Allowed subject to taste all above solution in landed and to point out the optimal salty taste of each subject. There were no significant difference in optimal gustation of salt among the hypertensive patients and control group. The optimal salt gustation of hypertensive patients with low salt diet was slightly lower than those with free diet The optimal salt gustation was higher in old aged persons regardless of diseases.

Although excessive intake of sodium is known to cause various diseases and threaten public health and policies for reducing overconsumption of sodium are being implemented, the theoretical research on sodium intake is incomplete. This study attempted to provide a policy basis by examining whether or not planned behavior theory, which is a typical health communication theory used to describe health-related behaviors, can be applied to explain sodium intake behavior. Especially, sodium ingestion behaviors were compared using the theory of actions planned for men and women as well as young people, middle-aged, and elderly persons, who are predicted to show differences in eating habits. In this study, questionnaires were prepared to measure the daily eating habits of subjects and subordinate factors of planned behavior theory: behavioral beliefs, outcome expectations, normative beliefs, compliance motivation, and control beliefs. Questionnaires were given to 93 college students and their families. As a result of the difference analysis and path analysis of the questionnaire responses, the following suggestions were obtained. First, age difference is more obvious than sex difference in terms of low salt intentions. For example, older people are healthier than younger people in terms of eating habits and health concerns. Second, the elderly are more likely to practice the low-salt formula when they are provided information on the benefits and effects of the low-salt formula compared to younger ones. Third, systematic efforts are needed to promote a culture that emphasizes the health benefits of a low salt diet rather than providing piecemeal information on the advantages and effects of a low salt diet.

The effect of dietary supplementation of sodium salt of isobutyric acid in low protein (10% CP) wheat straw based diet on nutrient utilization and rumen fermentation was studied in ruminally fistulated male crossbred cattle. The study included a 7 day metabolism and a 3 day rumen fermentation trials. The cattle were distributed into two equal groups of 4 each. The animals of control group were fed a basal diet consisting of wheat straw, concentrate mixture and green maize fodder in 40:40:20 proportion whereas branched chain volatile fatty acid (BCFA) supplemented group received a basal diet + isobutyric acid at 0.75 percent of basal diet. The duration of study was 36 days. The feed intake between experimental groups did not differ significantly and the average total DMI (% BW) was 2.01 and $2.28kg\;day^{-1}$ in control and BCFA supplemented diets. The dietary supplementation of BCFA improved (p<0.05) the DM, OM, NDF and cellulose digestibility by 4.46, 6.63, 10.57 and 11.31 per cent over those fed control diet. The total N retention on BCFA supplementation was improved (p<0.01) due to decreased (p<0.05) urinary N excretion. The concentrations of ruminal total N was 37.07 and $34.77mg\;100ml^{-1}$ in control and BCFA fed groups, respectively. Dietary supplementation BCFA significantly (p<0.01) reduced the ruminal ammonia N concentration as compared to control and the mean values ($mg\;100ml^{-1}$) were 13.18 and 9.42 in control and BCFA fed groups. The total VFA concentration was higher (p<0.01) in BCFA supplemented group (101.14 mM) than the control (93.05 mM). Among the VFAs, the molar proportion of acetate was higher (p<0.01) in BCFA supplemented group (71.07 mM) as compared to control (64.98 mM). However, the concentration of propionate and butyrate remained unchanged. Amino acids composition of bacterial hydrolysates was similar in both the groups. Ruminal outflow rate of liquid digesta was higher (p<0.01) in BCFA fed group ($67.56l\;day^{-1}$) than control ($52.73l\;day^{-1}$). It is concluded that the dietary supplementation of Na-salt of isobutyric acid in low protein diet improved the nutrient utilization and ruminal fermentation characteristics.
