The present study evaluated the effects of pomegranate peel (Granati pericarpium) extract on the lipid profiles and antioxidant biomarkers in mice fed a high fat and cholesterol diet: the measured biomarkers included the TBARS value, GPx, GR, SOD and GST activities. Body fat depositions were significantly decreased in the group that received pomegranate peel. In addition, the activities of GPx, GST and SOD were significantly higher in the liver and plasma of the pomegranate peel group than in the control group. Also, the pomegranate peel diet decreased lipid peroxidation of the liver and kidney. Alkaline single-cell gel electrophoresis (comet assay) showed that the DNA damage in the plasma of the pomegranate peel group was decreased compared to that of control. The present results show that a diet with added pomegranate peel exerts protective effects against oxidative DNA damage and lipid peroxidation possibly via effects on the free radical levels in mice fed a high fat and cholesterol diet.

Diet is an important focus in solidifying the fundamentals of health; thus, it is necessary to offer and manage accurate and correct information. This study examined the effects of body part satisfaction and attitude on diet, in female college students, who are known to be very interested in their appearances and tend to have a strong propensity to consume. The data were gathered using questionnaires answered by 101 female college students living in Daegu City, after classifying the women into normal weight and overweight groups, respectively. According to the analyzed results, there were no significant differences in satisfaction by body part between the normal weight and overweight groups, however, both groups were found to be dissatisfied with the following body parts, in the order of: thighs > legs > and hips. The motivation factors for weight control were found to be in order: not having a boyfriend > lacking of confidence > seeing slender entertainment stars, and there were no significant differences between the two groups. Finally, the main reasons for weight control were in order: appearance > health > getting a job. It is anticipated that these results will contribute to preparing systematic solutions to promote healthy diets and body satisfaction in society, and will help bring a desirable change in perceptions about diet.

Purpose: This descriptive study aimed to compare the perception of the acceptable foods for the neutropenic diet between nurses and patients by food type. Methods: The participants were 225 nurses working at chemotherapy wards and 71 patients in chemotherapy treatment. Data were collected with a self-administered questionnaire from January 2 to February 24, 2012, and analyzed with SPSS 12.0 program using descriptive statistics and the ${\chi}^2$-test. Results: Eighty-eight point eight percent of nurses and 76.1% of cancer patients thought the patients needed the neutropenic diets. The most important decisional criteria to determine dietary restriction was neutrophil count for nurses and food type for patients. The two groups showed significantly different allowance to raw fruits and raw vegetables, sterilized canned juice, fried vegetables, yogurt, uncooked tofu, salted fish, cooked fish, cooked shellfish, uncooked grain powder, jellified food, home-made bread/cookies, nuts including peanuts, instant coffee or tea and tea brewed. In general, patients were more permissive about the neutropenic diet than nurses. Conclusion: It is recommended to consider patients' preference as well as nurses' professional knowledge and publish standardized clinical diet guidelines for neutropenic patients with collaboration between nurses and patient representatives.

The purpose of this study was to analyze and consumption patterns diet/low-calorie food. Ubjects were 353 adult women aged 20s~50s. Ubjects were divided into three groups according to body mass index (BMI): Normal group (BMI>23.0), overweight group (23.0${\leq}$BMI<25.0), and obesity group (BMI${\geq}$25.0). This study collected all information by self-administrated questionnaires. The SPSS version 21.0 was used for analysis of data. The obesity group lower education level (p<0.001), higher age (p<0.001) and higher income (p<0.001) than normal group. However, score of health status was highest in normal group (p<0.001). Proportion of obesity group pill type diet/low-calorie (p<0.034), drug (diuretic, appetite suppressant and riental medicine) (p<0.001), and cosmetic surgery (p<0.001). The main reason for consumption of diet/low-calorie was control without starving (28.0%). Obese group emphasized manufacturer, ingredient and reputation, whereas the normal group emphasized price and expected effectiveness (p<0.001).

This study was designed in order to determine the influences of haw (Crataegus pinnatifida $B_{UNGE}$) on the lipid metabolism syndrome. Sprague Dawley rats, 7 weeks old, were given four different types of diets for 5 weeks: ND group (noncholesterolemic diet), HE group (non cholesterolemic diet+haw extract), CD group (cholesterolemic diet), CH group (cholesterolemic diet+haw extract). Concentrations of LDL-cholesterol, triglyceride, phospholipid, free cholesterol, cholesteryl ester, blood glucose were remarkably higher in the CD group than the other groups. But by treatment of haw extract group with cholesterolemic diet (CH group) were significantly decreased compared with CD group. Cholesteryl ester ratio was no difference between CD group and CH group. These results indicate that Crataegus pinnatifida $B_{UNGE}$ would be effective in lipid metabolism syndrome.

This study investigated the effects of dietary phyate reduction on the apparent absorption and biochemical parameters of iron status in young Korean women. Fourteen healthy, young women consumed low and high phytate diets for ten days of each experimental period. Duplicate diet samples, a fasting blood sample on day 9, and complete fecal samples for five consecutive days starting from day 5 of each diet period were collected. The iron content of diet and fecal samples were analyzed to calculate apparent absorption. Serum samples were analyzed for iron, ferritin, transferrin receptor and TIBC; transferrin saturation was also calculated. The apparent absorption of iron tended to increase in the low phytate period (32.51%) compared to the high phytate period (17.91%), but the difference was not significant (p=0.06). Serum ferritin decreased and serum transferrin receptor increased significantly during the low phytate diet although the mean values were within the normal range. Serum iron and transferrin saturation did not change significantly. In conclusion, the results indicated that reducing dietary phytate for ten days negatively affected iron nutritional parameters, but it moderately and positively affected apparent iron absorption in young Korean women. Further research on the long-term effects of a low phytate diet with an adequate iron content for vows Korean women is necessary.

We examined the effects of dietary nutrient content, feeding period, and feed allowance on compensatory growth, food use, chemical composition, and serum chemistry of juvenile olive flounder Paralichthys olivaceus. We placed 720 juvenile fish into 24 400-L flow-through round tanks (30 fish per tank).A $2{\time}2{\time}2$ factorial design (diet: control (C) and high protein and lipid (HPL) ${\time}$ feeding period: 8 and 6 weeks ${\time}$ feed allowance: 100% and 90% of satiation) was applied. Fish were hand-fed twice daily, based on the designated feeding schedule. Weight gain and food consumption were affected by both the feeding period and feed allowance, but not by diet. The food efficiency ratio was not affected by diet, feeding period, or feed allowance, but the protein efficiency ratio and protein retention were affected by diet and feeding period, respectively. We found that the full compensatory growth of fish was not achieved at a restricted feeding allowance.

This experiment was conducted to study the effect of dietary vitamin E on the lipid composi-tion of rats treated with carbon tetrachloride. Rats were divided into five groups I. e. C(soybean oil with vitamin E(40mg/kg diet)) EF(CCl4 with vitamin E deficient diet) 40E(CCl4 with vitamin E(40mg/kg diet) 400E(CCl4 with vitamin E(400mg/kg diet) 800E(CCl4 with vitamin E(800mg/kg diet) Body weight gain and food efficient ratio were not observed significant differences. The liver weight was significantly increased in the CCl4 treated groups but the liver weight of 800E group was significantly lower than that of EF group. In EF and 40E groups kidney weights were significantly higher compared to that of C group. The content of total lipid in liver of 40E and 400E groups were significantly higher than that of control group but in 400E and 800E groups the contents were significantly lower compared with that of EF group. The content of triglyceride in liver was significantly higher in the CCl4 treated group and the content of cholesterol was significantly higher in the EF and 40E groups but those of 800E group were significantly lower compared with those of EF group. In CCl4 administration groups were significantly higher than those of control group and 400E and 800E groups were significantly lower than those of EF group.

The effects of common Korean dietary fiber-rich foods(dried sea mustard, Lentinus edodes and Korean radish leaves) on total gut transit time of diet, serum cholesterol level and mineral apparent absorption ration and tissue level were investigated. Twenty eight male were divided into 4 groups and were fed a control diet(containing 2% cellulose) and three fiber supplementary diet mixed with 10% of the above dietary fiber rich foods for 4 weeks, respectively. Body weight gain and food efficiency ration were not affected by the supplementary diet of fiber but the total gut transit time of diet was shortened in all dietary fiber groups. The Lentinus edodes reduced significantly serum total cholesterol and increased the HDL-cholesterol/total cholesterol ratio at 4th week without and effect on calcium and iron apparent absorptions and tissue levels of the minerals. Radish leaves decreased significantly iron apparent absorption ration with a tendency to increase iron retention in spleen and did not alter serum cholesterol level. Serum cholesterol concentration and calcium and iron apparent absorptions were not significantly altered by the ingestion of sea mustard, while it had more soluble dietary fiber than mushroom and radish leaves.

Recently, the concept of personalized nutrition has been developed, which states that food components do not always lead to the same metabolic responses, but vary from person to person. Although this concept has been studied based on individual genetic backgrounds, researchers have recently explored its potential role in the gut microbiome. The gut microbiota physiologically communicates with humans by forming a bidirectional relationship with the micronutrients, macronutrients, and phytochemicals consumed by the host. Furthermore, the gut microbiota can vary from person to person and can be easily shifted by diet. Therefore, several recent studies have reported the application of personalized nutrition to intestinal microflora. This review provides an overview of the interaction of diet with the gut microbiome and the latest evidence in understanding the inter-individual differences in dietary responsiveness according to individual baseline gut microbiota and microbiome-associated dietary intervention in diseases. The diversity of the gut microbiota and the presence of specific microorganisms can be attributed to physiological differences following dietary intervention. The difference in individual responsiveness based on the gut microbiota has the potential to become an important research approach for personalized nutrition and health management, although further well-designed large-scale studies are warranted.
