Objectives: Increasing salt preferences with age are said to increase preferences of salty foods, thereby leading to greater sodium consumption, which has further implication for hypertension. This study examined the link between preference of salty taste and dietary factors and health-related risk factors in Korean elderly people. Methods: We studied 312 elderly individuals aged > 65 years (male, 100 and female, 212). With each subject, pleasant concentration of NaCl was estimated using the sip-and-spit method. Dietary habits, food preferences, consumption frequencies, anthropometric and biochemical assessment were assessed. Results: The pleasant salt concentration was significantly increased in individuals older than 75 years (p < 0.05). Subjects who liked high concentration of salt showed significantly higher preferences for salty foods (p < 0.001). Results showed significant effects (p < 0.01) of fruit & fruit juice consumption frequencies, MNA (mini-nutritional assessment), cognition score, BMI, body fat %, waist circumference, arm circumference, calf circumference, vitamin D level that subjects who likes low salty taste were higher than subjects who likes high salty taste. Conclusions: The preference for salty taste in the elderly was not correlated with hypertension. But, increased preference for salty taste with age and increased salty food preferences may result in higher sodium consumption. Therefore, nutritional education regarding lowering salt preference and favorable behaviors of low-salt diet is needed to improve the quality of life in the rural elderly.

This was a clinical trial study to aid the recovery of elderly female alcoholic liver disease patients by providing a balanced nutritional supplement comprising soymilk. All patients gave their consent before enrolling. The average demographics of the subjects were age 81.57 years, height 150.43 cm, weight 52.67 kg, and body mass index 24.15 kg/m². An increase in the daily consumption of fruits and fruit juice was observed after the patients had started taking the balanced meal as compared to before. Intakes of vitamin A, vitamin C, vitamin E, and cholesterol decreased after consuming soymilk, whereas vitamin B₁₂, niacin, folic acid, and dietary fiber significantly increased (P<0.05). Blood cholesterol and BUN levels showed a decreasing tendency. Our results indicate that consuming soymilk in a balanced diet for female patients afflicted with alcoholic liver disease helps improve their nutritional status by increasing the nutrients lacking in the body.

Objectives : To satisfy the demand of good treatment of constipation Methods : we investigated the literatures of Oriental Medicine about Constipation. Results: 1. There are three categories of etimological factors of constipation, that is, endogenous, exogenous and non-exo-endogenous factor. The endogenous factor is caused by seven emotions, called depression of Ki and stagnation of Ki. The exogenous factor is six excessive atmospheric influences, for example, wind, cold, dampness, heat and dryness. And the non-exo-endogenous factors are overfatigue, improper diet, stagnated blood and deficiency of Ki and blood that comes from old age, long disease and after delivery. 2. Classification: According to cause of disease it is classified by constipation due to cold, heat, wind, dryness, retention of undigested and phlegm. According to Internal Organs there are constipation due to deficiency syndrome of the stomach, excess syndrome of the stomach, deficiency syndrome of kidney and splenic constipation. And Differentiation of syndromes according to Ki and blood, there are constipation of deficiency type and excess type. There are constipation due to stagnation and deficiency of Ki, deficiency of blood and stagnated blood. 3. Principles and Methods of treatment 1) Herbal Medicine (1) Excess type [1] Constipation due to heat : Seunggitang(承氣湯) and Majainwhan(麻子仁丸) [2] Constipation due to stagnation of Ki : Samatang(四磨湯) and Yukmatang(六磨湯) (2) Deficiency type [1] Constipation due to deficiency of Ki : Whanggitang(黃?湯) [2] Constipation due to deficiency of blood: Yunjangwhan(潤腸丸) [3] Constipation due to cold : Jechunjun(濟川煎) and Banyuwhan(半硫丸) 2) Enema therapy: It is a method to induce defecation by honey or pig's bile juice for weak people. 3) Acupuncture and Moxibustion: Acupoints used to treat constipation are BL25, ST25 and TE6. Moxibustion at CV8, CV6 is good for constipation due to cold. (4) Diet therapy: It is very important that we eat meals regularly and defecate on the same time even if you don't. And we have to eat food like fruits, vegetables and beans. (5) finger pressure: Finger pressing around these points like ST25, SP25, BL25, BL31, BL32, BL33 and BL34 is good for it. (6) Kigong therapy: Abdominal breathing (7) Old man' s constipation: Hip bath or diet therapy is commended. Laxation with lubricant like Supungyunjangwhan(搜風潤腸丸) is used. (8) Women' s constipation: After delivery, we have to administer tonifying prescription Sipjundaebotang(十全大補湯) and enema can be used. Conclusion : We have to examine the cause of disease and bowl movement carefully. After comprehensive analysis of the data gained by the four methods of diagnosis, we diagnose and treat patients on the base of overall of symptoms and signs.

The aim of this study was to determine the association between, smoking, exercise, sex, and dietary carotenoids ($\alpha$-carotene, $\beta$-carotene, $\beta$-cryptoxanthin, lutein + zeaxanthin, lycopne) intake in Korean middle-aged adults. Food-frequency questionnaire were analyzed from 304 healthy adults (115 men, 189 women) aged 20 - 59. The self-administered questionnaire contained subject s habitual diet and alcohol intake were the previous 3 months. Data on frequency of 102 foods, including vegetables, fruits, beverages and legumes were analyzed. Total dietary carotenoids intake were 27.13 $\pm$ 3.09 mg/d for men and 26.71$\pm$ 2.82 mg/d for women. It was found that smoking had no significant contribution to the dietary intake of carotenoids. Among other lifestyle factors that had significant correlation was the amount of exercise time. The increases in exercise time was associated with increase in carotenoids intake (r= 0.121, p : 0.04). The major contributors of $\alpha$-carotene and $\beta$-carotene were carrots consumed as single-food item or carrot juice. Lutein and Zeaxanthin intake mainly came from spinach and most lycopene intake was derived from tomato products not fresh tomatoes. Persimmon was the major contributor of $\beta$-cryptoxanthin. These findings provide valuable information on understanding the unique pattern of dietary intake of Korean, which might help identify the risks for developing various diseases.

The primary objective of this research was to investigate the recognition, preference and the present using status of yam for the data which will be useful to make consumers intake more yams and to develop more yam processed products. Almost all respondents who had eaten yams liked it, and Andong people eat more yams than Daegu people. About 60.3% respondents who like yams cited the reason was "it's good for health". Among the respondents who had eaten yams recognized it as nutritional, healthful, and diet food compared with the respondents who had not eaten yams. Recognition degree was higher when the preference for yams was higher. Among the types of yam processed cooking, according to intake ratio, yam juice formed 38%, followed by bleaching(17%) etc. Among the types of yam processed food, powdered tea formed 34%, followed by yam gruel(24%), yam drinks(19%) etc. It showed that respondents eat very few foods made from yams and yam processed food. As for purchasing yam processed food, the result showed that the main concerns of the respondents were the "ratio of yams"(24.9%), followed by "tastes"(21.3%) etc. The largest group (29.4%) of the respondents suggested that the improvements of yams were "diversification of the processed food" followed by "improved taste"(26.4%) while 62.5% of the respondents indicated that they would buy yams after its improvement, which showed a good prospect of yam processed food.

This study was performed to determine the sensory evaluation and mechanical characteristics of lemon red ginseng-pyun. Lemon red ginseng-pyun was made with lemon juice(21.4%), sweet potato starch(6.7%), water(53.3%), sugar(13.3%), honey(5.3%) and various concentrations of red ginseng powder(0, 2, 4, 6, 8, 10%). The quality characteristics of the sample were estimated in terms of pH, color difference, texture profile analysis and sensory evaluation. The pH of lemon red ginseng-pyun showed no significant difference among the different ratios of red ginseng. With increasing red ginseng powder addition, the lightness was significantly(p<0.05) lower, and a value and b values were significantly(p<0.05) higher. In sensory evaluation, with increasing red ginseng powder addition, the color and bitter taste of lemon red ginseng-pyun were stronger, while clarity of the 10% added red ginseng was significantly(p<0.05) lower than that of the 0% added red ginseng. Elasticity, hardness, chewiness, softness. sweet taste and overall acceptability were not significantly different in any group. In texture profile analysis, chewiness, cohesiveness, gumminess and hardness were significantly(p<0.05) increased in the 10% added red ginseng but springiness was not significantly different in any group. Overall acceptability was related to texture, appearance, overall taste and sweet taste of lemon red ginseng-pyun. Therefore, development of lemon red ginseng-pyun with no sugar or artificial sweeteners is encouraged as a healthy diet for diabetes and hypertension patients, because red ginseng is defined as a functional foods.

The characteristics of the exocrine pancreatic secretions in pigs and its hormonal regulation as influenced by dietary lipids are reviewed. There is clear evidence that the secretion of lipolytic enzymes is positively correlated with the amount of fat consumed by the pig. For example, there was an increase in the specific lipase activity by 83% after the dietary fat content was increased from 5% to 25%. Moreover, it was shown that also the quality of fat has an influence on exocrine pancreatic secretions. Peroxidized canola oil stimulated total lipase secretion much more than non-peroxidized oil. The influence of fatty acid composition on exocrine pancreatic secretions is discussed equivocally. Some authors showed that saturated fats stimulated the exocrine pancreatic secretions more than unsaturated. Others showed that the chain length of fatty acids had a strong influence on pancreatic secretions as well. Due to the different surgical methods used for sampling of pancreatic juice and wide variety of fats and oils used in these studies, direct comparisons between studies are extremely difficult to make. Plasma levels of hormones such as cholecystokinin (CCK), neurotensin (NT) and peptide YY (PYY) are influenced by the nutrient composition of the diet. With increasing amounts of fat present in the small intestine, the release of these hormones was stimulated. There is evidence that CCK release is dependent on the chain length of the fatty acids. Medium chain triglycerides stimulated the CCK release more than long chain triglycerides. Neurotensin was released more by unsaturated than by saturated fatty acids; similar results were observed for the PYY release. However, results are contradictory and further investigations are warranted that focus on the underlying mechanisms involved in the regulatory response of the exocrine pancreas to lipids of different origin.
