The theory-the doctrine of Confucius and Mencius was an objective existance in Chinese dietary culture history, but it was ignored in the last two thousand years. In addition, some people misunderstood Confucius' and Mencius' thoughts and statements. This paper believes that the doctrine of Confucius and Mencius is Confucius' and Mencius' diet opinions, thoughts, theories and basic style in their diet experiences. Confucius' diet experience and Mencius' diet experience were alike, and Mencius' experience carried on Confuius' and theirs were the same in some sections. They all stay their diet standard to their stomach and don't persue good meal. They all thought resolving people's diet was important for a country and for the politic problems. Mencius succeeded Confucius' diet thoughts and put them to the theories-diet principle, diet standard, and diet morality. This paper deeply discusses theory, developing history condition and the affection and position in Chinese diet history of the doctrine of Confucius and Mencius.

The present study conducted to examine the effects of proteins from different sources on Ca excretion in 6 healthy young adult Korean women. The subjects were given meat protein diet for 5 days and soy protein diet for subsequent 5 days. the two diets were similar in protein and Ca contents. Urinary and fecal samples were collected for the last 2 days of each diet period and were analyzed for Ca and P. The results were as following ; 1) Mean daily urinary calcium excretion was 126.5$\pm$22.70mg for meat protein diet and 83.7$\pm$17.19mg for soy protein diet and the difference was significant (P<0.025). 2) Fecal Ca excretion did not show significant difference between two experimental preiod ; 466.9$\pm$73.68 mg of meat portein diet 284.4$\pm$54.96mg for soy protein diet. 3) Three out of six subjects showed negative balance on meat protein diet, but only one showed negative balance on soy protein diet. The averageof the balances on meat protein diet was -65.4 $\pm$68.19 and that of soy protein diet was 155.3$\pm$52.28 ; the difference was significant(P<0.025). 4) Urinary P excretion tended to be higher on meat protein diet but was not significant compared to soy protein diet . Fecal P excretion was significantly higher (P<0.001) on soy protein diet. Overall P balances for meat protein diet and soy protein diet were 219.94 mg and 229.46mg respectively (P<0.05). The above results show that urinary Ca excretion was significantly higher on meat protein diet but fecal excretion did not show significant difference between meat protein diet and soy protein diet. The overall Ca balance was significantly higher on Soy protein diet compared to meat protein diet.

The study aims to examine college students' practice characteristics related to diet and to identify factors determining their diet practice. The subjects were college students (N=387) in Youngnam region; a questionnaire survey was conducted in May, 2007. The data were analyzed by SPSS Windows. The results are as follows: first, the ratio of female students going on a diet is higher than that of male students. Second, according to the BMI, female students more regard themselves as being overweight than male students do, although they are underweight or normal weight. Third, in the interest in diet, almost half the students think of themselves as being "somewhat" or "much" concerned about diet. Fourth, the binary logistic regression analysis shows that the significant factors affecting female students' diet practice are the variables of "grade", "interest in diet", "body image evaluation in the individuals", "information/education requirement on dietary guidelines", and "necessity to go on a diet". On the other hand, the significant variables affecting male students' diet practice are the variables of "to take diet- or health-related courses", "interest in diet", "diet knowledge", and "diet practice".

This study was done to determine the effect of antioxidants added perilla oil diet on the content of cholesterol, vitamin E, and lipid peroxide in serum and tissue of rats. Four groups of experimental diets, such none added perilla oil diet, ascorbic acid added perilla oil diet, vitamin E added perilla oil diet, EDTA added perilla oil diet were fed ad libitum to the 4 weeks white male rats of Sprague-Dawley strain. The results obtained are summarized as follow: 1) The body weight gain in all experimental diet groups was higher than the control gorup and EDTA added diet group was lower than the other experimental diet group, while food intake in vitamin E added diet group was the highest and vitamin C added diet group was the lowest in the control group. 2) Total cholesterol levels in serum of all experimental diet groups were lower than that of the control group and especially the level of total cholesterol in none added diet group and vitamin C added diet group were significantly lower than that of control group. 3) HDL-cholesterol levels of all experimental diet groups were lower than that of the control group and especially none added diet group was significantly lower than that of control group. 4) The activities of glutamic oxaloacetic transaminase (GOT) in serum of all experimental diet group except EDTA added diet group were higher than that of the control group and especially none added diet group was significanly higher than that of the control group. The activites of glutamic pyruvic transaminase (GPT) in serum of all experimental diet groups except vitamin C added group were higher than that of control group. 5) Vitamin E levels in serum of none added diet group and vitamin C added diet group were lower than that of the control group and vitamin E added diet group and EDTA added diet group were higher than that of the control group. 6) Vitamin E levels in liver of all experimental diet groups were higher than that of control group and especially none added diet group and vitamin E added diet group were significantly higher than that of the control group. 7) Lipid peroxide in serum of all experimental diet group were lower than that of control group and especially EDTA added diet group. 8) Lipid peroxide in liver and spleen of all experimental diet groups were higher than that of the control group and lipid peroxide in kidney of all experimental diet groups except EDTA added diet group were higher than that of the control group. Four these results, as vitamin C, vitamin E and EDTA added diets have an effect to lipid peroxide by antioxidants, it could be suggested that perilla oil diet has required to add antioxidant because it has not sufficient vitamin E for antioxidant and intake and overtake level of perilla oil diet should be studied to go ahead.

The purpose of this study was to investigate the anti-obesity effects of crude saponin (CS) in Korean red ginseng (KRG) on rats fed a high fat (HF) diet. Methods: Male Sprague-Dawley (SD) rats were divided into a normal diet group and a high-fat (HF) diet group. The HF diet group became obese from being fed a HF diet over five weeks. The normal diet group were fed a normal diet. Each CS group of the normal diet group and HF diet group was administered CS (200 mg/kg, i.p.) for three weeks, the control group of both types was administered normal saline (1ml/kg, i.p.) instead of CS. Each group had 5 rats. Results: After administration of CS, the body weight, food consumption, adipose tissues, and expression of appetite peptides such as leptin and neuropeptide-Y (NPY) were investigated in the HF diet group as well as the normal diet group. Administration of CS reduced body weight, food intake, and fat content in the HF and normal diet groups. After CS administration, NPY expression and leptin were lower in the HF diet group. Conclusions: Our results suggest that CS may be useful in the treatment of obesity, especially of type qixu (氣虛).

This study was performed to investigate the effect of sodium intake on blood pressure and blood parameters. 20 young adult women were fed the diets containing 290.5 mEq (high-Na diet) and 51.3 mEq (low-Na diet) Na for 6 days, respectively. BMI, DBP, and MBP were significantly lower in low-Na diet than those in high-Na diet. 20 subjects were divided into 3 groups according to the salt-sensitivity. In salt-sensitive group, decreases in SBP, DBP, and MBP by low-Na diet were shown. And there were not significant difference in blood pressure of salt-resistant group between high- and low-Na diet. In count-reactive group, MBP in low-Na diet was significantly higher than that in high-Na diet. Hemoglobin, creatinine, uric acid, and haptoglobin levels in serum were significantly higher in low-Na diet than those in high-Na diet. Among groups with different salt-sensitivity, increments of haptoglobin by low-Na diet were shown in salt-sensitive and counter-reactive groups. Actually, low sodium diet affects not only the blood pressure, but other biochemical parameters which in turn affect an individual overall health. Also salt-sensitivity should be considered as an important determinant. Therefore, for the patients who need restricted Na diet, it would be suggested that various biochemical changes and individual salt-sensitivity should be carefully considered along with dietary Na manipulation.

During last few decades dietary guidelines for the weight management mainly have focused on a low-fat, high carbohydrate diet. Carbohydrate was supposed to be low-dense, highly satiating as well as it affects little on the lipogenesis. Although low-fat diet has significant weight-reducing effect, the loss was modest and usually regained after cessation of the diet. Furthermore, low-fat, modest-carbohydrate diet did not impact on the ever increasing rates of overweight and obesity. Alternative approaches include low-carbohydrate diet, high-carbohydrate diet and low-glycemic index diet. Although none of above mentioned diet have sufficient evidence for standard weight management diet, short-term efficacy and safety are being approved continuously. Low-carbohydrate diet contains less than 45% of carbohydrate in daily energy consumption, it is claimed to have more satiating effect and to improve metabolism. However, low compliance due to the limitation of food choice should be considered on prescribing the diet. High-carbohydrate which contains 90% of carbohydrate in total daily energy consumption, is effective in providing satiety and lowering total calorie intake and cholesterol. On the other hand, nutritional unbalance should be took into account. Low-glycemic index diet is based on the theory that contemporary diet contains significantly less fiber and unrefined carbohydrate, therefore insulin secretion is disturbed. Because low glycemic index food slowly increase blood glucose and insulin level, it induces much satiating effect and may decrease calorie ultimate intake. However, poor standardization of glycemic index is one of the main obstacle for the diet to be applied in the clinic. Meanwhile, high fructose food and beverage should be discouraged because it has little satiating effect and may cause insulin resistance. High fiber food is another recommendation for healthy, lean diet.

The Ca and P balance studies were carried out with two different diets varying Ca levels : the current Korean RDA level(normal Ca diet) and the high level (High Ca diet) which was determined by adding 2SD to mean Ca intake of all subjects. The subjects were sever healthy adult woman, aged from 25 to 32 years old. The metabolic studies were conducted for two weeks with a days recess in between : during the fist week with normal Ca diet and during the second week with high Ca diet. The composition of nutrients excepting Ca of both diets was similar to subjects usual intake. The result were summarized as follows: Mean daily Ca intake was 728.8mg from norma Ca diet and 945.5mg from high Ca diet. Fecal excretion of Ca increased significantly(p<0.05) on high Ca diet, but urinary excretion of Ca did not show any differences between the two diet periods. There were also no significant differences in Ca retention between the two diet periods but it tended to be greater during high Ca diet period: 112.1mg/day during normal Ca diet period vs 208.2mg/day during high Ca diet period. Mean apparent Ca absorption was 41.2% on normal Ca diet and 42.1% on high Ca diet, indicating it was not affected by high Ca intake level used in this study. On the contrary, P retention was significantly increased up to 109.4mg/day with high Ca diet as compared to- 41mg/day with normal Ca diet. There were no significant differences in fecal and urinary excretion of P but those to be lower during high Ca diet period. The above results showed that higher Ca intake more than current RDA(700mg/day), in the level of 945.5mg/day, could increase Ca retention through Ca absorption comparable to the rate appeared on RDA level intake. P retention was also improved by high Ca intake. Therefore, higher Ca intake than the current RDA level seemed to produce favorable effects on bone health in adult women. However, the current RDA level seemed to be relatively appropriate, considering the results that all the subjects but one maintained positive Ca balance with normal Ca diet.

This study was carried out to study influence of antioxidants on serum and tissue of rats fed with thermally oxidized oil. The experimental animals used 30male rats of sprague-dawley weighting $150{\pm}25g$. They are divided into 5 groups and fed to experimental diets which are composed of 15％ thermally oxidized oil in addition to ascorbic acid, Vitamin E, Ethylendintrioteraaceticacid(EDTA) and none added oxidized oil by heat and fresh soybean oil group. Thermally oxidized oil was prepared from the soybean oil by heating at $180^{\circ}C$ for 30 hours. After feeding for 4 weeks, the result are as follows; 1. Body weight gain were lower B diet group than A diet group. 2. Total cholesterol levels in serum of all experimental diet groups except B diet group were higher than that of A diet group. 3. HDL-cholesterol levels of all experimental diet groups except E diet group were lower than that of A diet group. 4. The activities of GOT, GPT in serum of all experimental diet groups except B diet group and D diet group were higher than that of A diet group. 5. Vitamin E levels in serum of E diet group were highest than that of all experimental diet groups, and Vitamin E levels in liver of A diet group were highest than that of all experimental diet groups. 6. Lipid peroxide in Serum were highest B diet group than that of all experimental diet groups and the other experimental diet group significantly lower than that of the A diet group. 7. Lipid peroxide in liver of all experimental diet group except E diet group were significantly higher than that A diet group and lipid peroxide in kidney of all experimental diet group except B diet group were lower than that of A diet group. Four these results, as Vitamin C, Vitamin E, and EDTA added diets have effect of thermally oil by antioxidants, it could be suggested that thermally soybean oil diet has required to add antioxidant because it has not sufficient Vitamin E for antioxidant and intake and overtake level of thermally soybean oil diet should be studied to go ahead.
