  • Effects of 5 and 10% dietary supplement tablets containing green tea, buckwheat, and grape leaf extracts on atherosclerosis, and plasma and hepatic lipid compositions in hamsters fed antherogenic diet [modified AIN-76A containing 10% coconut oil (w/w), 0.05% cholesterol] were examined. Compared to atherogenic diet only groups, addition of supplement to atherogenic diet-fed group significantly down-regulated triglyceride and total cholesterol levels in plasma and liver. F1B hamsters fed atherogenic diet had greater foam cell accumulation compared to control and those fed atherogenic diet with addition of supplement. Lipid metabolisms of plasma and liver increased with addition of supplement dose-dependently, whereas aortic lipid accumulation decreased. These results indicate tablets supplemented with green tea, buckwheat, and grape leaf extracts have potential to prevent cardiovascular diseases in golden Syrian hamsters.

  • This study was performed to investigate the effects of garlic on uncoupling protein 2 (UCP2) transcriptional regulation of UCP2-luciferase transgenic mice fed on a high fat diet to induce obesity. To examine the transcriptional regulation of UCP2, we generated transgenic mice with a UCP2 promoter (-1,830/+30 bp) containing luciferase as a reporter gene. UCP2-luciferase transgenic mice were fed a 45% high-fat diet for 8 weeks to induce obesity. Subsequently, mice were maintained on either a high-fat control diet (TG-CON), or high-fat diets supplemented with 2% (TG-GL2) or 5% (TG-GL5) garlic for a further 8 weeks. Dietary garlic reduced body weight and energy efficiency ratio in the TG-GL5 group, compared to the TG-CON group. Furthermore, garlic supplementation significantly decreased white adipose tissue fat mass and plasma levels of triglycerides, total cholesterol, and leptin in the TG-GL2 and TG-GL5 groups, compared to the TG-CON group. Specifically, UCP2 promoter activity in metabolic tissues such as liver, white adipose tissue, brown adipose tissue, and skeletal muscle was increased by garlic supplementation. These results suggest that dietary garlic was partially associated with an increase of UCP2 transcriptional activity in metabolic tissues for decreasing obesity.

  • Red Chinese cabbage is rich in anthocyanins, with beneficial effects on anti-obesity and lipid profiles. The purpose of this study was to examine the anti-obesity effects of red Chinese cabbage. Four-weeks old Spague-Dawley male rats were divided into four groups for six weeks as follow: Normal Diet (ND), High Fat Diet (HFD), HFD + Red Chinese Cabbage Diet (RCD), HFD + Red Chinese Cabbage Juice (RCJD). After six weeks, the liver weight was significantly higher in the HFD group than in the other groups, and the RCD and RCJD groups showed similar values to the ND group. The epididymal fats were significantly higher in all high fat diets (HFD, RCD, RCJD) than in the ND group and there was statistical significance in the post-tests when comparing the RCD and RCJD groups with the HFD group. Triglycerides significantly decreased in the RCD group. In conclusion, red Chinese cabbage is rich in anthocyanins, with beneficial effects on organ weight and lipid profiles.

  • We evaluated the effects of newly developed functional food containing Bacillus polyfermenticus SCD as the main material on the lipid and antioxidant metabolisms of hypercholesterolemic rats. Thirty male SD rats were divided into three groups after a 1-week adaptation period and were fed with a high fat-cholesterol diet (control), or with a high fat-cholesterol diet supplemented with low or high doses ($3.1\;{\times}\;10^6\;cfu/day$ or $3.1\;{\times}\;10^8\;cfu/day$) of B. polyfermenticus SCD and other physiological active materials for 6 weeks. Both doses of B. polyfermenticus SCD significantly reduced hepatic total cholesterol and triglycerides, while increasing the fecal excretion rates of total lipid, total cholesterol and triglycerides. B. polyfermenticus SCD increased the total radical trapping antioxidant potential (TRAP). The erythrocytic glutathione peroxidase activity in the B. polyfermenticus groups was significantly lower than that in the control group. Plasma TRAP levels exhibited a highly significant negative correlation with hepatic total cholesterol while a significant positive correlation was detected between fecal total cholesterol and plasma TRAP. This hypolipidemic and antioxidative effect of B. polyfermenticus SCD seemed to be unrelated to its dosage. These results suggest that functional food containing B. polyfermenticus SCD can improve oxidative stress and hepatic lipid profiles by enhancing the excretion of cholesterol and triglycerides in feces of rats fed with high fat-high cholesterol diet.

  • Adequate intake of nutrients exert a profound influence on the physical and spiritual development of children. Thus, it is important to children and their mothers about nutrition and selection of nutritious foods. In order to underline the importance of nutrition for children, this study investigated and analyzed food habits of children expecially those in preschool ages, to obtain basic data to develop effective educational materials related to nutrition. dietary habits of 61 boys and 44 girls in the average age of six were surveyed through their mothers. Results therefrom are as follows : 1. Only 17 per cent of the mothers questioned replied that they considered the balance of diet in preparing meals, while 58.1% of the mothers gave precedence to the liking of their family . The lower the educational level of a mother , the higher her stress on the food preference of her family. 2. Seventy six of the mothers said they understand the basic food group , but only one mother displayed an accurate knowledge about it. 3. As for between meal eating , 82.9% took fruits, 68.6% milk, 35.2 bread, and 33.3% cookies. 4. Problems with food habits of children were : Unbalanced diet for 43.8% of children ,eating of snacks at irregular intervals for 26.7% and TV impact for 5.7%. 5. Children's food habits are greatly influenced by their parents, In the case of animal liver, 32.1 % of the children surveyed do not like to eat it, while 35.8% have never tasted it . 27.9% of children also do not like to eat cereals. Children's likes and dislikes with regarded to foods were influenced greatly by their parents. Thus, it is urgent to educate mothers about balanced diet and basic food group. Children will have to be taught to understand unfavorable effects of unbalanced diet so that they may correct their unsound food habits. This study also indicated the need for developing new cooking methods for those food items which are very liked by children to be a major cause of their unbalanced dietary habits.

  • The purpose of this study was to investigate the effects of the ethanol extract of Cynanchum wilfordii (ECW) on the blood lipid profile of hypercholesterolemic rats. Thirty 7-week-old male Sprague-Dawley rats were allowed free access to either a normal diet (AIN-93 diet), or 1% high-cholesterol diet with or without 0.5% or 1% ECW for 5 weeks. After sacrifice, the rat serum lipid profile was analyzed. The diets containing ECW decreased body weight gains compared to the normal diet. Serum HDL-cholesterol levels of ECW-fed groups were significantly increased in the hypercholesterolemic groups and normal groups (P<0.05). When 1% ECW was fed to the normal group, total cholesterol level was increased. Moreover, treatment of ECW in hypercholesterolemic groups yielded a dose-dependent and highly significant decrease in the atherogenic index as compared to the control. These results suggest that intake of Cynanchum wilfordii may help reduce the risks of hypercholesterolemia by increasing blood HDL-cholesterol and lowering the atherogenic index.

  • The purpose of the current study was to examine the influence of different maternal nutrition treatments during pregnancy on body weight, muscle fiber number, carcass traits, and pork quality traits of offspring. A total of 18 crossbred sows (Landrace${\times}$Yorkshire${\times}$Duroc) were randomly assigned to one of three nutritional treatment groups; control, high energy, and high protein. The control group was fed a standard diet, the high energy group was fed a diet that contained 30% increased metabolizable energy, and the high protein group was fed a diet that contained 30% increased limiting amino acids compared to the control. The sows in each group were fed equal quantities of each diet (1.9 kg/d) for the entire gestational period. A total of 36 piglets from each sow were used to evaluate changes in body weight, muscle fiber number in the longissimus dorsi muscle at birth, carcass traits, and pork quality traits. Birth weight of offspring born to sows in the high energy diet group was significantly higher compared to the high protein diet group (p<0.05). However, body weight of offspring after birth was not significantly different between the groups. Muscle fiber number for the longissimus dorsi muscle at birth was not significantly different between the groups. In addition, there were no significant differences in carcass traits or pork quality traits between offspring born to sows in the control group and those born to sows that received high energy or high protein diets during pregnancy. Based on these results, it appears that maternal nutrition treatment during pregnancy, regardless of whether it is with high energy or high protein diets, does not have a significant effect on body weight, muscle fiber number at birth, carcass traits, or pork quality traits.

  • The present study has been undertaken to investigate the effects of ginseng extract on the activities of several enzymes in serum of rats fed lard and alcohol. Thirty-five males of Sprague-Dawley strains weighed about 130 g were divided into 7 groups, each group receiving a different diet for 10 weeks; i.e. basal diet plus 15% lard, basal diet plus 5% alcohol, basal diet plus 5% ginseng extract, basal diet plus 15% lard and 5% ginseng extract. Determinations were carried out on the net weight gain, food efficiency ratio, weight of organs, and AST, ALT, lactate dehydrogenase, alkaline phosphatase activities in serum of rats. The results obtained were as follows:Rats given feed containing lard and alcohol showed significant decrease in net weight gain, but ginseng extract caused an increase in food efficiency ratio. Lard supplementation caused an increase in the weight of liver, kidney, spleen, but another groups did not. AST, ALT, ALP, LDH of serum were significantly increased in lard and alcohol containing group but ginseng extract feeding decreased enzyme activities compared to lard and alcohol containing group. The above results suggest that ginseng extract would prevent the metabolic disease of liver by preventing hyperlipemia caused by high fat diet.

  • Vitamin K has been suggested to plays a role in bone metabolism. The objective of this study was to determine whether vitamin K2 supplementation is related to bone mineral density, bone formation markers, and bone resorption in ovariectomized (OVX) rats. Forty Sprague-Dawley female rats (body weight, $200{\pm}10$ g) were divided into four groups: a sham group fed a control diet, a sham group fed a vitamin K2 supplemented diet, OVX fed a control diet, and OVX fed a vitamin $K_2$ supplemented diet (3.5 mg vitamin $K_2$/kg diet). All rats were fed the experimental diets for 6 weeks, and deionized water was provided ad libitum. Serum alkaline phosphatase activity (ALP), osteocalcin, and urinary deoxypyridinoline crosslink values were measured as markers of bone formation and resorption. Bone mineral density (BMD) and bone mineral content were measured in the spine and femur using PIXImus (GE Lunar Co., Madison, WI, USA). No significant differences in body weight gain, food intake, or food efficiency ratio were observed between the control and experimental groups. Serum ALP, osteocalcin, and urinary crosslink values were not significantly different between the vitamin $K_2$ supplemented groups. No significant differences were observed for any of the variables in the sham group. Spine BMD values were significantly lower in the OVX than those in the sham groups. Spine and femur BMD per weight of vitamin $K_2$ tended to be higher than the control diet group within the OVX group, but no significant differences were observed. In conclusion, dietary vitamin $K_2$ supplementation may have a beneficial effect on spine and femur BMD in OVX rats. Further research is needed to understand the potential benefits of vitamin $K_2$ on bone loss in OVX rats.

  • This study was to evaluate the effectiveness of the weight control program for female college students. The program was composed of diet and behavioral modifications for 8 weeks. A total of 78 participants enrolled the weight control program. Upon completion of the program, 53 participants experienced weight loss and 25 did not. The intakes of carbohydrate and fat were significantly decreased in both groups. However, the total diet quality index-international (DQII) scores as well as individual scores such as variety scores for protein source and adequacy scores for vegetable, fiber, calcium and vitamin C and moderation scores for empty calorie food were increased significantly in weight loss group only. In the weight loss group, weight, BMI, body fat, percent body fat and waist-hip ratio were decreased significantly. In addition, compared to the weight gain group, the weight loss group had higher changes in weight (weight loss group: -2.6% vs weight gain group: 1.5%, p < 0.001), body fat (-6.0% vs 0.0%, p < 0.001), percent body fat (-3.1% vs -0.3%, p < 0.001), waist-hip ratio (-1.0% vs 0.5%, p < 0.001) and BMI (-2.6% vs 1.3%, p < 0.01). There was no difference in blood profiles between the two groups. The changes in DQI-I scores were significantly correlated with the changes in body weight (r = -0.239, p < 0.05) and BMI (r = -0.224, p < 0.05), indicating that effective nutrition education could help improve diet quality leading to successful weight management among female college students.
