  • Objective : Recently, obesity has increased at an alarming rate and is now a worldwide health problem. Natural dietary supplement, $CharmSlim^{(R)}$(C), is mixed pills, which consists of beans, black sesames, kelps, onions, adlay seeds, anchovies, pyogo mushrooms, green tea. Our study was performed to determine the weight-loss effects of natural dietary supplement, based on natural ingredients, in mice fed high-fat diet with an abundance of carbohydrates. Methods : Four groups of male ICR mice were fed different diets during 6 weeks: normal diet(NOR), high-fat (15%, w/w) diet(HF), high-fat supplemented with natural dietary supplement powdered 5%(C5) and 10%(C10) groups. We measured the changes of food intake, body weight and adipose tissues weights. Also we examined levels of lipid profiles in serum. Results : Body weight, liver weight and food efficiency ratio were significantly higher in the HF group than in NOR group. After 6 weeks of treatment, body weight, liver weight and adipose tissues weights (epididymal, perinephric, visceral and BAT) were significantly decreased in the C10 group when compared to the control HF group. The C10 group had markedly lower serum levels of total cholesterol and triglyceride when compared with HF group. Conclusion : These results demonstrate that this dietary supplement can suppress the increased lipid profiles, body weight and fat gains, thus could be considered as an effective adjunct in the treatment of obesity.

  • This study was observed the effect of n6 and n3 polyunsaturated fatty acids of dietary corn oil and fish oil which was supplemented with similar levels of tocopherol in high fat diet on the levels of tocopherol, malondialdehyde ( MDA) productions of plasma and tissues of rats. Also RBC hemolysis, superoxide dismutase (SOD) and glutathione peroxidase (GSH Px) activities In liver were determined. Male Sprague Dawley rats were fed high fat (40%Cal) diet which was different only In fatty acid composition for 6 weeks. Dietary (arts were beef tallow(BT) as a source of saturated fatty acid, corn oil(CO) for n6 linoleic acid (LA) and fish oil(FO) for n3 eicosapentaenoic acid(EPA) + docosahexaenoic acid (DHA). Plasma and liver tocopherol levels were lowered by n3 PUy4 but there was no difference in malondialdehyde(MDA) level by different dietary PUFA. However, MDA content of RBC and hemolysis were increased by n3 PUFA. MDA content, superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities in liver were increased in more unsaturated dietary fat groups. Especially, SOD activity was increased in proportion to the degree of fat unsaturation.

  • 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.

  • This study was carried out to evaluate the effect of Acanthopanacis Cortex boiling extract solutions on the fat accumulation in the obese rats induced by the oral high fat administration for six weeks. Total cholesterol, neutral fat and adipose acid of ACR groups were lower than the control group. During the feeding experiment, LDL and VLDL were increased while HDL was decreased in all groups. Insulin and cortisol were higher than the control group, due to the fat accumulation. Based on the above results, it was shown that it is possible to improve fat accumulation induced by high fat dietary through using the oral administration of Acanthopanacis Cortex boiling extract solutions.

  • 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.

  • Obesity is a global pandemic that is increasing throughout most of the world. Increases in obesity are not restricted to highly industrialized countries, but have been observed in newly developed and developing countries as well. Obesity is associated with increased risk for non-insulin dependent diabetes mellitus, coronary artery disease, and some types of cancer. Tragically, eliminating food shortages in developing countries may result in substituting heart disease, diabetes, and cancer for malnutrition. There are many approaches to reducing obesity, including dietary modification, surgical interventions, and drug therapies. However, only dietary modification has the potential to be effective on a global scale. Public health measures in the United States have sought to reduce obesity by reducing the intake of dietary fat. While these efforts have succeeded in reducing dietary fat, obesity has continued to increase, suggesting that moderate fat reduction may not be effective. Other proposed diets include low-carbohydrate diets, low glycemic index diets, and very low fat diets. While all of these diets may be effective for some people, they are not satisfactory for public health policy. In fact, the ratio of fat to carbohydrate may not be as important as previously believed. Humans may be well suited to adapt to diets as varied as a high carbohydrate tropical diet consisting mostly of fruits to the high fat Eskimo diet consisting largely of animal foods. Either extreme may be healthful if providing adequate, but not excessive, energy and adequate amounts of micronutrients. Public health measures may need to focuss on reducing the overconsumption of inexpensive and convenient foods.

  • Objective: The current study aimed to investigate the impact of high-fat diets composed of different animal and vegetable fat sources on serum metabolic health markers in Japanese quail, as well as the overall lipid content and fatty acid profiles of the edible bird tissues following significantly increased dietary lipid supplementation. Methods: Fifty seven male quail were divided into six groups and fed either a standard diet or a diet enriched with one of five different fats (22% coconut oil, lard, palm oil, soybean oil, or sunflower oil) for 12 weeks. The birds were subjected to an oral glucose tolerance test following the feeding period, after which they were euthanized and blood, liver, breast, and thigh muscle samples collected. Total fat content and fatty acid profiles of the tissue samples, as well as serum uric acid, triglyceride, cholesterol, total protein, albumin, aspartate transaminase, and total bilirubin concentrations were assessed. Results: High-fat diet feeding had no significant effects on the glucose tolerance of the birds. Dietary fatty acid profiles of the added fats were reflected in the lipid profiles of both the liver and breast and thigh muscle tissues, indicating successful transfer of dietary fatty acids to the edible bird tissues. The significantly increased level of lipid inclusion in the diets of the quail used in the present study was unsuccessful in increasing the overall lipid content of the edible bird tissues. Serum metabolic health markers in birds on the high-fat diets were not significantly different from those observed in birds on the standard diet. Conclusion: Thus, despite the various high-fat diets modifying the fatty acid profile of the birds' tissues, unlike in most mammals, the birds maintained a normal health status following consumption of the various high-fat diets.

  • Consumer's demand for higher dietary fiber and lower fat in processed foods are increasing. This study developed a low fat and high dietary fiber snack using egg whites and dry fermented radish powder obtained from Dongchimi fermentation. Quality characteristics, such as hardness, color, fat content and total dietary fiber, of the developed snack were conducted along with a hedonic test. As the amount of the fermented powder increased in the formulation, water content and snack hardness decreased. Up to 14.5% radish powder was added (or 9.54% dietary fiber; dry weight, w/w) to the formulation, and hedonic test found snack containing 4.8% (w/w) powder showed the highest scores for overall acceptability.

  • To investigate effects of ethanol and dietary fat on growth and bichemical indices of liver tissue and blood in rats 40 male rats of Sprague-Dawley wtrain weighing about 160g were divided into 5 groups (low-fat diet group ethanol-administered low-fat diet group high-fat diet group ethanol-administered high-fat diet group and commercial diet group) and fed expe-rimental diets for 8 weeks. Ethanol-administered groups consumed ethanol corresponding to 22 cal% which was considered as moderate drinking. Neither the ethanol intake nor the dietary fat level affected calorie intake. Nonetheless the low-fat diet group with ethanol had the lowest growth rate and 2-fold increase in the concentration of plasma triglyceride. There was no effect of ethanol and dietary fat level on contents of protein lipid and lipid composition of liver tissue. The level of lipid peroxide of liver tissue tended to be increased by ethanol intake but the increase was statistically insignificatnt. The low-fat ethanol group had lowered hepatic mitochondrial respiration rate and deformed structure of mitochondria of hepatocytes.

  • The effects of dietary levan, high-molecular-weight $\beta$-2,6-linked fructose polymer, on adiposity, serum leptin and UCP expression in rats fed high fat diet were studied. The adipose tissue hormone, leptin has been proposed to be involved in the regulation of food intake and energy expenditure. Uncoupling protein (UCP), a mitochondrial protein that uncouples the respiratory chain from oxidative phosphorylation, generates heat instead of ATP, thereby increase energy expenditure. To determine whether the dietary levan may have the anti-obesity effect, 4 wk old Sprague Dawley male rats fed high fat diet for 6 wks to induce obesity, and subsequently fed one of three diets for further 6 wks: 1) high fat (40% of calories) diet without levan 2) with 3% (w/w) levan 3) with 5% levan. For the comparison, control group fed AIN-76A diet. Visceral and peritoneal fat masses were lower in high fat diet with levan groups compared to high fat diet group. The effect of levan was dose-dependent. Adipocyte size was significantly reduced in the levan diet groups compared to the no levan diet group. Serum cholesterol level was not affected by levan containing diet, while the serum HDL cholesterol level was higher in leven diet groups. In addition, serum triglyceride level was markedly reduced by levan containing diet, thus lower than that of control group. Serum leptin was reduced by levan containing diet and lower in 5% levan group compared to 3% levan group (p < 0.001), as a result, serum leptin and insulin levels of 5% levan group were reduced to level of control group. Futhermore, the serum leptin level reflected the adiposity. The expression of UCP 1, and UCP 2 in brown adipose tissue was up-regulated by levan containing diet. In conclusions, levan containing diet reduced adiposity and serum triglyceride but increased UCP expression in the obese rats fed high fat diet. (Korean J Nutrition 35(9) : 903~911, 2002)
