We wanted to classify the food constitutionally. That was used to make the constitutional diet plan. And we checked through the clinical test. So the food was classified constitutionally by Sasang Constitutional Medicine(SCM). Constitutional diet plan was considered to Nutrition and Constitution. The clinical trial(use Taeumin diet plan) had performed during 8 weeks. We checked the Health and Nutrition condition. As the result, the Taeumin diet plan didn't change the health and nutrition condition of each constitution in good health. That could be presumed that constitution diet plan do not harm to healthy person.

This study was conducted to investigate the dietary pattern of children with unbalanced diet in school feeding. Children who eat only what they like among elementary school students were selected for this survey. The general characteristics, nutrition knowledge, eating behavior, food intake frequencies and food preferences of the subjects were investigated compared with control group. The subjects were consisted of a total of 160 children : 92 male students(unbalanced-diet group, 46; control group, 46), and 68 female students(unbalanced-diet group, 34; control group, 34). There was no significant difference in nutrition knowledge between the unbalanced-diet group and the control group. Dietary behavior of control group turned out to be more desirable than that of the unbalanced-diet group. In addition, 68.7% of the unbalanced-diet group and 13.8% of the control group hated to eat vegetables. The result of food intake frequency indicates that the control group turned out to be higher in their intake of fish, cereals, vegetables, seaweeds, fats & oils and Kimchi compared with unbalanced-diet group. Intake frequency of minerals and vitamins of the control group was higher than that of the unbalanced-diet group. On the other hand, the unbalanced-diet group turned out to be higher in sugar intake. Children showed the greatest preference of fruits. The unbalanced group turned out to prefer sugar and beverages more than the control group. These results suggest that the desirable dietary habits of children should be formed with the help of nutrition education designed for behavior modification.

The purpose of this study was to find the effect of dietary polyunsaturated fat on of vitamin levels E, total cholesterol and HDL-cholesterol in serum of Spraque-Dawley male rats. Experimental rats were fed for 4 weeks with corn oil, perilla oil, lard at a level of 10% and 20% respectively. The results obtained are as follows; 1. Body weight gains were similar to all groups and food intake was significantly lower in all experimental diet groups than control diet group, especially 20% corn oil diet group was the lowest among the experimental diet groups. 2. Vitamin E levels in serum were significantly lower in 20% corn oil and 10%, 20% perilla oil diets groups than control diet group. 3. Serum total cholesterol levels were significantly higher in 20% perilla oil diet group which was significantly lower in vitamin E level than control diet group, and serum total cholesterol levels of 10%, 20% lard diets groups were significantly higher than control diet group. 4. Serum HDL-cholesterol levels were significantly lower in 20% perilla oil diet group which was significantly lower in vitamin E level than control diet group, and serum HDL-cholesterol levels of 10%, 20% lard diets groups also were significantly lower than control diet group.

An extract obtained from germinated brown rice was evaluated for protective effects against the adverse effects of a chronic high fat diet. C57BL6/J mice were divided into three groups; normal diet + water group (ND), high fat diet + water group (HD), high fat diet + brown rice water extract group (HD + BE) and fed for 8 weeks (6 day/week). The ND group diet was 11 kcal fat $\%$. The HD group and HD + BE group diet were 42 kcal fat $\%$. Weight gains were not significantly different between groups. However, abdominal fat $\%$ was 1.6-fold higher in the HD group than HD + BE group. Feed consumption was significantly higher in the ND group than HD group. Serum triglyceride, total cholesterol and LDL-cholesterol increased with a high fat diet, but decreased by brown rice water extract administration to the high fat diet group. Serum HDL-cholesterol decreased by the high fat diet, but increased by the brown rice wate extract administration. Also, serum HDL-cholesterol/total cholesterol ratio was 2.3-fold higher in the HD + BE than the HD. Liver triglyceride and total cholesterol were not significantly different among groups. These data suggest that brown rice water extract administration improves the serum lipid profiles of C57BL/6J mice.

This study investigated the effect of porphyran drink extracted from Porphyra yezoensis on serum and liver cholesterol contents in hypercholesterolemic rats. We divided rats into 5 diet groups; normal diet, control diet fed high cholesterol diet, $1\%$ porphyran drink diet with control diet $(1\%\;PD),\;2\%$ porphyran drink diet with control diet $(2\%\;PD),\;3\%$ porphyran drink diet with control diet ($3\%$ PD). Food intake was not significantly different among groups, but weight gain was significantly lower in porphyran drink group $(1\%,\;3\%)$ than control group. Liter weight was significantly lower in $3\%$ porphyran drink group than control group. Serum triglyceride and total cholesterol contents were significantly lower in porphyran drink group than control group. Serum HDL-cholesterol contents was elevated as porphyran drink intake level increased. Hepatic triglyceride and total cholesterol concentrations were significantly decreased in porphyran drink group compared to control diet. These results suggested that addition of porphyran drink in hypercholesterolemic rats has an effect on the improvement of serum and liver cholesterol.

Objectives: The study aimed to examine whether healthy diet score was associated with stress and social support among 472 Chinese college students in Korea. Methods: The study participants were 472 (187 male, 285 female) Chinese college students in Gyeong-gi area. From April 2013 to Oct 2013, participants were asked to fill out questionnaires on healthy diet score (20 questions), stress (20 questions), and social support (20 questions). Each question was scored by a 5-point Likert scale (total scores of each questionnaire were ranged from 20 to 100). Questions on healthy diet were sub-categorized as 'Healthy food eating (HFE)', 'Healthy eating habits (HEH)', and 'Avoidance of unhealthy food (AUF)'. Reliability test was conducted with Cronbach's ${\alpha}lpha$ (${\alpha}=0.79$). Results: Healthy diet score was higher in participants who stayed longer in Korea, who spoke Korean language fluently, and who assessed his or her own health status as very good. Adjusted means of healthy diet scores were estimated after adjusting for age, gender, body mass index, duration of staying, and Korean language fluency. According to tertile categories, participants with low tertile stress but high tertile social support showed the highest score of healthy diet ($72.59{\pm}1.45$), whereas participants with high tertile of stress but low tertile of social support had the lowest score of healthy diet ($59.22{\pm}1.54$). As for the three sub-categories of healthy diet score, the score of HFE increased as the score of social support increased. Conclusions: Our findings suggested that social support system is beneficial to alleviate stress and to improve healthy diet score.

This study was performed to investigate effects of Chiarella vulgaris on lipid metabolism in rats fed high fat diet. Sixty 6-week-old male Wistar rats were divided into two groups; normal diet group and high fat diet group, then the rats in each group were further divided into three subgroups and fed 0%, 5% and 10% (w/w) chlorella-containing diets, respectively, and raised for 9 weeks, Serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activity and total protein and albumin concentration were not different among groups. Serum total lipids and liver TG concentration were significantly lower in 5% and 10% chlorella groups than 0% chlorella group in high fat diet groups (p<0.05). Serum TG, serum total cholesterol, liver total lipid and liver total cholesterol concentrations were significantly lower in 10% chlorella groups than 0% chlorella group in high fat diet groups (p<0.05). Fecal total lipid, TG and total cholesterol excretions were significantly higher in 5% and 10% chlorella groups than 0% chlorella groups in normal diet and high fat diet groups, respectively (p<0.05). These results suggest that Chlorella vulgaris is effective for prevention of dyslipidemia which may be due to the modulation of lipid metabolism and increased fecal excretion of lipid.

BACKGROUND/OBJECTIVE: The incidence of colorectal cancer (CRC) has been attributed to higher intake of fat and protein. However, reports on the relationship between protein intake and CRC are inconsistent, possibly due to the complexity of diet composition. In this study, we addressed a question whether alteration of protein intake is independently associated with colonic inflammation and colon carcinogenesis. MATERIALS/METHODS: Balb/c mice were randomly divided into 4 experimental groups: 20% protein (control, 20P, 20% casein/kg diet), 10% protein (10P, 10% casein/kg diet), 30% protein (30P, 30% casein/kg diet), and 50% protein (50P, 50% casein/kg diet) diet groups and were subjected to azoxymethane-dextran sodium sulfate induced colon carcinogenesis. RESULTS: As the protein content of the diet increased, clinical signs of colitis including loss of body weight, rectal bleeding, change in stool consistency, and shortening of the colon were worsened. This was associated with a significant decrease in the survival rate of the mice, an increase in proinflammatory protein expression in the colon, and an increase in mucosal cell proliferation. Further, colon tumor multiplicity was dramatically increased in the 30P (318%) and 50P (438%) groups compared with the control (20P) group. CONCLUSIONS: These results suggest that a high protein diet stimulates colon tumor formation by increasing colonic inflammation and proliferation.

The purpose of this study was to examine the impact of isoflavones on lipid concentrations and hepatic LDL receptor mRNA level in growing female rats. Twenty four rats (body weight $75\pm5g$) were randomly assigned to one of two groups, consuming control diet or isoflavones supplemented diet (57mg isoflavones/100g diet). All rats has been fed on experimental diet and deionized water ad libitum for 9 weeks. The concentration of triglyceride and total cholesterol were measured in serum and liver. Serum HDL cholesterol was measured. Hepatic LDL receptor mRNA level was tested by RT-PCR. Supplementation of isoflavones did not affect weight gain, mean food intake and food efficiency ratio. Serum total cholesterol and non-HDL cholesterol of isoflavones supplemented rats were significantly lower than those of control rats (p<0.05). But hepatic cholseterol was not influenced by supplementation of isoflavones. Hepatic LDL receptor mRNA level not significantly different between control group and isoflavones supplemented group. Therefore, isoflavones may be beneficial on serum cholesterol and non-HDL cholesterol lowering in growing female rats.

The purpose of this study was to identify dietary patterns among children and adolescents in Korea and to examine their associations with obesity and some blood profiles. One day food consumption data measured by 24-hour recalls on 2704 subjects aged 1 to 19 were used from 2001 Korea National Health and Nutrition Survey. The data of blood profiles available in the ages of 10 or older was also used. After categorizing each food consumed into 29 food or food groups, five dietary patterns were derived through a factor analysis and subjects were classified into three major dietary patterns via a cluster analysis using the factor scores. Three dietary patterns were identified as 'traditional diet' (25.6%), 'westernized-fast food' (6.2%), and 'mixed diet' (68.2%). The 'traditional diet' pattern had a higher percentage in boys. Both the 'traditional diet' and the 'westernized-fast food' had higher proportions of adolescents (12-19 y) than younger children, while the 'mixed diet' had a higher percentage of preschool children (1-5 y). Obesity rate analyzed within each age group showed no differences among 3 dietary pattern clusters. Blood pressure and all plasma profiles were not different among dietary patterns when adjusted with age and gender. Conclusively, children and adolescents in Korea had three distinct dietary patterns, which were associated with gender and age. These patterns could be useful to plan nutrition interventions for teenager health promotion.
