This study investigated the anti-obesity effects of Coriandrum sativum L. ethanol extracts in a high fat diet-induced obesity model (DIO). We confirmed the anti-obesity effects by analysing the expression of the related proteins, weight gain, dietary intake, dietary efficiency, blood biochemistry, histological analysis and western blot analysis. After oral administration of Coriandrum sativumL. ethanol extracts at concentrations of 250 and 500 mg/kg, a significant improvement in dietary efficiency, reduction in weight gain, triglycerides, total cholesterol and LDL-cholesterol in blood lipid was observed for 8 weeks. In addition, improvement in blood glucose and metabolism confirmed through glucose tolerance test was observed. Further, the concentration of alanine transaminase (ALT) in blood was significantly decreased, which improved the fatty liver caused by high-fat diet intake as confirmed by liver tissue analysis. This phenomenon was confirmed to decrease the expression of fat accumulation-related PPARγ and FAS protein in the liver tissue. Especially, it is believed that FAS, a liposynthetic enzyme, has a stronger inhibitory effect than PPARγ. Therefore, Coriandrum sativum L. ethanol extract is thought to improve obesity by reducing blood lipids levels, improving glucose metabolism and inhibiting synthesis of the fat that accumulates in the liver in high-fat diet-induced obesity animal models.

Good health and longevity is the goal of huamn beings. Recently, 'Dietary treatment' has become influential as one of the means for it in western medicine. Whereas in oriental medicine, 'Dietary treatment' was not recognized as therapeutic method but care of health. in this paper, the viewpoints of 'Dietary treatment' in oriental and western medicine was compared and searched for new possibilities in oriental medicine. And the results were as follows. 1. In oriental and western medicine, food was obviously recognized as a source of nourishment, and moreover oriental medicine took even a human soul into consideration. 2. Western medicine made much of nourishment and was analytical and therapeutic-centered. on the other hand, oriental medicine took a serious view of prevention and care of health. 3. Oriental medicine considered that intake of food was a adoption of Gi(氣) and then it helped a circulation of Gi and beneficial for the production of Jeong(精). 4. The principles of diet in oriental medicine was reasonable combination of food, balance of Oh-Mi(五味), temperance of food and intake by physical constitution.

BACKGROUND/OBJECTIVES: Non-alcoholic fatty liver disease (NAFLD) is a leading cause of chronic liver disease and is closely associated with metabolic syndrome. In the present study, we observed the effect of ethanol extract of Allium fistulosum (EAF) on NAFLD and have suggested the possibility of using EAF as a natural product for application in the development of a treatment for NAFLD. MATERIALS/METHODS: The preventive effect on hepatic lipid accumulation was estimated by using an oleic acid (OA)-induced NAFLD model in vitro and a Western diet (high-fat high-sucrose; WD)-induced obese mouse model. Animals were divided into three groups (n = 7): normal diet group (ND), WD group, and WD plus 1% EAF group. RESULTS: EAF reduced OA-stimulated lipid accumulation in HepG2 cells in the absence of cellular cytotoxicity and significantly blocked transcriptional activation of sterol regulatory element-binding protein 1 and fatty acid synthase genes. Subsequently, we investigated these effects in vivo in mice fed either ND or WD in the presence or absence of EAF supplementation. In comparison to the ND controls, the WD-fed mice exhibited increases in body weight, liver weight, epididymal fat weight, and accumulation of fat in hepatocytes, and these effects were significantly attenuated by EAF supplementation. CONCLUSIONS: Allium fistulosum attenuates the development of NAFLD, and EAF elicits anti-lipogenic activity in liver. Therefore, EAF represents a promising candidate for use in the development of novel therapeutic drugs or drug combinations for the prevention and treatment of NAFLD.

Data are limited on the association between dietary patterns and screen time among Korean adolescents. The present study identified dietary patterns of 691 adolescents, aged 13-18 years, who had participated in the Third Korean National Health and Nutrition Examination Survey (KNHANES III) and analyzed their associations with screen time. Screen time was defined as the time spent watching TV, using a computer, or playing video games was calculated as a sum of all these times. Dietary patterns and their factor scores were derived from a food frequency questionnaire using the factor analysis method. To analyze the association between dietary patterns and screen time, we conducted multiple linear regression analysis. We also performed multiple logistic regression analysis to estimate odds ratios (OR) of excessive screen time (2 hours or longer per day) and 95% confidence intervals (CI). We identified 2 dietary patterns labeled "the Korean healthy dietary pattern" and "the Western diet and fast foods pattern". The former included mixed grains, legumes, potatoes, red meat, eggs, fish, dairy products, fruits, vegetables, seaweeds, and mushrooms, whereas the latter included noodles, bread, red meat, poultry, fast foods, snack, and soft drinks. After controlling for potential confounding factors, factor scores for the Korean healthy dietary pattern were inversely associated (P-value for trend < 0.01) and those for the Western diet and fast foods pattern were positively associated with the screen time (P-value for trend < 0.01). Adolescents in the top tertile of the scores for the Korean healthy dietary pattern had a multivariable-adjusted OR [95% CI] of 0.44 (0.25-0.75) for excessive screen time compared with those in the lowest tertile. On the basis of these findings, adolescents who have excessive screen time may need to be encouraged to consume a more healthy diet.

Stomach contents of Hexagrammos otakii collected from mid-western coast of Korea were analysed to determine dietary composition, and ontogenetic and temporal dietary variations. Fish total length (TL) ranged between 5.6 and 32.4 cm. H. otakii primarily consumed amphipods, carid shrimps and teleosts, but also ate various benthic crustaceans and other invertebrates with small amounts. Carid shrimps and teleosts dominated the diet of both immature and mature fishes. Amphipods and polychaetes were secondary, and the former more frequently consumed by smaller specimens, while the latter was more abundant in the diets of larger fishes. DISTLM (distance-based linear modelling) showed diet composition of H. otakii varying significantly with TL, season and water temperature, but did not with maturity.

Objectives: This study was carried out to measure knowledge, attitude, and practice and related factors of low-salt diet among university students. Methods: Data from a convenience sample of 251 nursing and engineering students of two universities in south-western part of Korea were collected during March 16~20, 2015 using a self-reporting questionaire and urine test. The instruments developed by Lee and Song(1999) were used to measure knowledge and practice, and Ahn(2013) for attitude toward low-salt diet. A spot urine salt stick($SaltSinal^{(R)}$) was also used to evaluate practice of low-salt diet. Data were analyzed using SPSS 21.0, and t-tests, ANOVA, Pearson correlation, and Scheffe test were used. The study was IRB approved. Results: Knowledge, attitude, and practice of low-salt diet was low and spot urine salt level was high among university students. Knowledge and attitude were higher and spot urine salt level was lower among nursing students. Knowledge and attitude were related to gender and drinking. Living arrangement, monthly allowance, smoking, frequency of eating-out, frequency of breakfast were shown not to be related to knowledge and attitude. None of the variable investigated were significantly related to practice of low-salt diet. However, spot urine salt was related with gender, living arrangement, and smoking. Conclusions: A rigorous health education is necessary in order to lower dietary salt among university students. Considering frequent eating-out among university students, it is also very important to lower salt amount in foods sold on- and off-campus.

Objectives : The aim of this study is to investigate the preventive effect of Puerariae Flos ethanol extract (PE) on methionin and choline deficient (MCD)-diet-induced Nonalcoholic fatty liver disease (NAFLD) in C57BL/6J mice. Methods : In the in vivo experiments, C57BL/6J mice were divided into 4 groups; Normal group, Control group, MCD+PE 100 group, and MCD+PE 300 group. After 4 weeks, body weight, liver weight, biochemical parameters for liver function test, histological changes, reverse transcription polymerase chain reaction (RT-PCR), and Western blot were assessed. Results : Mice lost body weight with the MCD-diet and the MCD+PE 100 group and MCD+PE 300 groups lost less than the control group, though showed no statistical significance. Liver weights were decreased by the MCD diet, but MCD+PE 300 groups were increased significantly. In the liver function test, all the values were decreased with the MCD-diet, MCD+PE 100 group and MCD+PE 300 groups were increased significance. In histological findings of the livers, MCD-diet induced severe fatty accumulation in the livers, but this fatty change was reduced in the MCD+PE 100 group and MCD+PE 300 groups was inhibited respectively. In lipid accumulation factors (such as SREBP-1c, $C/EBP{\alpha}$, PPAR-${\gamma}$), MCD+PE 100 group and MCD+PE 300 groups showed inhibitory effect on liver lipogenesis by reducing associated gene expressions caused by MCD diet. Conclusions : We were able to know that Puerariae Flos ethanol extract (PE) shown hepatoprotective effects via a decrease on the hepatic lipogenesis factors in the experimental NAFLD Models.

Purpose: It has been previously reported that breast tumor incidence, growth, and metastasis are stimulated by high-fat diet but reduced by caloric restriction. However, few studies have elucidated the effects of dietary change from a high-fat diet after breast cancer initiation. Therefore, in this study, we attempted to provide practical assistance to breast cancer prevention and management by investigating the effects of dietary change from a high-fat diet to normal diet on breast cancer growth and metastasis. Methods: The experimental animals were divided into 2 groups (high-fat diet control [HFC] group and diet restriction [DR] group) and consumed a high-fat diet for 8 weeks. 4T1 cells were transplanted into subcutaneous fat or tail vein to measure the growth and metastasis of breast cancer. The HFC and DR groups continuously ingested either high-fat diet or AIG-93G diet for 5 weeks or 3 weeks, respectively. Cell proliferation and apoptosis markers from tumor tissues were analyzed by Western blot analysis. The data were analyzed using the SPSS 25.0 package program. Results: The results show that the DR group significantly reduced breast tumor initiation, growth, and tumor tissue weight compared to the HFC group. The DR group suppressed tumor growth by decreasing proliferation and inducing apoptosis through down-regulation of Bcl-xL and up-regulation of caspase-3 activity. Furthermore, the DR group significantly reduced numbers of metastasized tumors in lung tissues. Conclusion: These results suggest that dietary change from a high-fat diet to normal diet decreased breast growth by reducing cell proliferation and inducing apoptosis and metastasis. Taken together, these results indicate that dietary change to a low-fat and balanced diet might suppress breast tumor growth and metastasis even after tumor diagnosis.

To enjoy a healthy life, it is important to have a well-balanced diet. However, in today's society, there is an increase in the consumption of preprocessed foods and frequency of eating out. Also the western diet, which is becoming move popular worldwide, contains relatively high levels of protein and fat, and a low amount of fiber, Furthermore, the increased availability of favorite foods has created a condition were the individual diet is less variable. With these conditions, it is difficult to maintain a diet that is nutritionally balanced. With these unbalanced diets, which are difficult to change, there has been an increase in adult disease and health problems, such as colon and breast cancer, It is speculated that metabolites for carcinogens are produced from diet components and that intestinal bacteria contribute to the production of these metabolites. Therefore, it is necessary to evaluate the relationships between health, diet, and intestinal microflora. Soybean oligosaccharide is composed of water-soluble saccharides that have been extracted from soybean whey, a by-product from the production of soy protein. This is mainly a mixture of mono-, di-, tri-, and tetrasac-charides, with the principle components being the oligosaccharide raffinose and stachyose. When consumed by humans, the oligosaccharides cannot be digested in the human duodenal and small intestinal mucosa, and these are selectively utilized by beneficial bifidobacteria in intestines. The results of acute and subacute toxicity tests, soy-bean oligosaccharides were nonpoisonous. Soybean oligosaccharides promote the growth of indigenous bifido-bacteria in the colon which by their antagonistic effects, suppress the activity of putrefactive bacteria. Also, they reduce toxic metabolites, detrimental enzymes and plasma lipid, and increase in the frequency of bowel evacuation and fecal quantities. Consequently, soybean oligosaccharides as functional foods components have potential roles in the prevention and medical treatment of chronic adult diseases. The study of processing property and physiological function of soybean oligosacchavides and development of high oligosaccharide variety allow the creation of new and exciting foodstuffs that aye functional healthy.

Objectives : The aim of this study was to investigate the effects of Gamisaenggan-tang on high fat diet induced nonalcoholic fatty liver disease. Methods: Rats were randomly divided into four groups. The Normal group was fed a solid diet containing 10% fat. The Gamisaenggan-tang (GS) group was fed a solid diet containing 10% fat and Gamisaenggan-tang (90mg/100g body weight). The Control group was fed a solid diet containing 60% fat. The HFD-Gamisaenggan-tang (HFD-GS) group was fed a solid diet containing 60% fat and Gamisaenggan-tang (90mg/100g body weight). Six weeks later, rats body weight, liver weight, serum ALT, GGT, ALP levels were measured. Histological findings (Oil red O staining), hepatic triglyceride, TNF-${\alpha}$, and TGF-${\beta}$ levels in the liver tissue were studied. Results: Average body weight of the HFD-GS group was significantly less than that of the Control group. There were no significant liver weight differences among each group. The GGT levels of the HFD-GS group were significantly less than those of the Control group. However, there were no significant differences in the ALT or ALP levels among the groups. TNF-${\alpha}$ protein production assessed by western blot analysis was reduced by Gamisaenggan-tang. Greater fat accumulation was observed in the liver tissue of the Control group than in the HFD-GS group, which means the Gamisaenggan-tang has an inhibitory effect on the accumulation of fat in the liver. Conclusion : The results suggest that Gamisaenggan-tang can be potential candidate for the treatment of nonalcoholic fatty liver disease in clinics.
