This study investigated the effects of the nutrition education on body weight, visceral fat and diet quality in the postmenopausal women. The subjects (n = 101) were randomly divided into two groups: Nutrition education + Exercise (NEE) group (n = 51) and Exercise only (EO) group (n = 50). Nutrition education was consisted of counseling in portion control, food selection for low carbohydrate, high fiber food items and for the improvement in micronutrient intakes and diet quality. After 6 months, the reduction in the body weight and visceral fat area was significantly greater in the NEE than in the EO group. The NEE subjects were further divided into two groups according to the amount of visceral fat area reduction; high visceral fat area loss (HVL) group with a visceral fat area reduction 2.35% or greater and low visceral fat area loss (LVL) group with a reduction less than 2.35%. In the HVL group, the reduction in body weight, BMI, percent body fat, waist to hip ratio and visceral fat area was significantly greater than that in the LVL group. We observed a significant increase in the serum HDL-cholesterol level and a decrease in systolic blood pressure, fasting blood sucrose, total and LDL-cholesterol levels in the HVL group compared to the LVL group. The energyadjusted protein, fiber, calcium, vitamin $B_6$, vitamin C, vitamin E intakes were significantly increased in the HVL compared to LVL group. The index of nutritional quality (INQ) and mean adequacy ratio (MAR) were also increased in the HVL group compared to the LVL group. These results show that our nutrition education program was an effective intervention measure for the reduction of body weight and visceral fat, blood pressure, glucose and lipid levels in the blood and also for the improvement of nutrient intake and diet quality in postmenopausal women who are overweight.
Thinned fruits, apple, pear and peach were investigated into chemical components and physiological activities. On proximate compositions, crude protein, crude fat and ash of thinned fruits were higher than those of ripe fruits, showing lower carbohydrate in thinned fruits. The contents of inorganic substance were Ca, Mg, P, Na, K and B in order. On heavy metals, As, Cd, Cr and Hg were not detected and Ge, Mo, Ni and Pb were trace. Organic acid in thinned apple and peach were detected as tartaric acid, citric acid, malic acid and succinic acid, but thinned pear did not contain citric acid. Free sugars in thinned pear and peach were composed of glucose, fructose and sucrose but sucrose was not detected in thinned apple. Contents of insoluble dietary fiber in thinned fruits were higher than soluble dietary fiber. The thinned apple extracts showed high antioxidant activity. Nitrite scavenging activity of thinned apple and pear extracts were 71∼80 e/o and 61∼63% at pH 1.2, respectively. Tyrosinase inhibitory activity of thinned pear extracts was 61.0∼89.4 %, however peach extinct showed no activity.
Comparisons of the physico-chemical characteristics between white Atlantic potatoes and violet Bora Valley potatoes were performed. According to the results, Bora Valley had 7% higher moisture content than Atlantic, but there were no differences in crude fat and crude ash contents. Bora Valley, however, had about 3% less crude protein content than Atlantic. In a vitamin C analysis by HPLC, the Atlantic and Bora Valley potatoes contained 14% and 39% vitamin C, respectively, indicating that Bora Valley contained about twice as much of the vitamin as Atlantic. In a vitamin C analysis by HPLC, the Atlantic and Bora Valley potatoes contained 14% and 39% vitamin C, respectively, The dietary fiber content of Bora Valley was 3.12 g per 100 g higher than that of the Atlantic variety. While Atlantic contained neither glucose nor fructose, both sugars were measured in the Bora Valley potatoes, and there was no difference in sucrose content between the cultivar.
Cardiovascular diseases (CVDs) are the most common cause of death in patients with nonalcoholic fatty liver disease (NAFLD) and dyslipidemia is considered at least partially responsible for the increased CVD risk in NAFLD patients. The aim of the present study is to understand how hepatic de novo lipogenesis influences hepatic cholesterol content as well as its effects on the plasma lipid levels. Hepatic lipogenesis was induced in mice by feeding a fat-free/high-sucrose (FF/HS) diet and the metabolic pathways associated with cholesterol were then analyzed. Both liver triglyceride and cholesterol contents were significantly increased in mice fed an FF/HS diet. Activation of fatty acid synthesis driven by the activation of sterol regulatory element binding protein (SREBP)-1c resulted in the increased liver triglycerides. The augmented cholesterol content in the liver could not be explained by an increased cholesterol synthesis, which was decreased by the FF/HS diet. HMG-CoA reductase protein level was decreased in mice fed an FF/HS diet. We found that the liver retained more cholesterol through a reduced excretion of bile acids, a reduced fecal cholesterol excretion, and an increased cholesterol uptake from plasma lipoproteins. Very low-density lipoproteintriglyceride and -cholesterol secretion were increased in mice fed an FF/HS diet, which led to hypertriglyceridemia and hypercholesterolemia in Ldlr-/- mice, a model that exhibits a more human like lipoprotein profile. These findings suggest that dietary cholesterol intake and cholesterol synthesis rates cannot only explain the hypercholesterolemia associated with NAFLD, and that the control of fatty acid synthesis should be considered for the management of dyslipidemia.

Panax ginseng marc is produced from fresh ginseng roots during processing and is generally treated as industrial waste. The primary aim of this study was to improve its utilization in the dairy industry as a potential high-value resource. Yogurt was prepared from 11% skim milk powder, 0.1% pectin, 10% sucrose, and ginseng marc ethanol extract (GME, 0.5% and 1.0%) in milk, and was inoculated with a 0.02% yogurt culture (Lactobacillus acidophilus, Bifido-bacterium longum, and Streptococcus thermophilus). After fermentation at $40^{\circ}C$ for 6-8 h, the physicochemical properties of samples were analyzed by the AOAC, Kjeldahl, and Soxhlet methods. Sensory evaluation was performed based on consumer acceptability scores with a 7-point scale, and antimicrobial effects were measured by the agar plate method. The moisture, crude protein, crude fat, and ash contents of yogurt supplemented with 1% GME were $85.06{\pm}0.06%$, $4.41{\pm}0.01%$, $4.30{\pm}0.05%$, and $0.81{\pm}0.03%$, respectively, with no significant changes noted from those of yogurt without GME (control), except for an increase in the crude fat content. The sensory scores of color, flavor, texture, overall taste, and overall acceptance of yogurt supplemented with below 1% GME did not differ significantly (p<0.05) to those of the control yogurt. In addition, the growths of Staphylococcus aureus, Bacillus cereus, Listeria monocytogenes, Escherichia coli, and Enterobacter sakazakii were inhibited during fermentation and storage. These results suggest that GME could be used in dairy products as a supplement and in the food industry as an antimicrobial material.
This study investigated the effects of the nutrition education and exercise program on body composition, dietary intakes and physical fitness in obese women. The subjects were 44 obese women (BMI${\geq}$ 25 kg/$m^2$) who had been participating in nutrition education (1 time/week) and exercise program (3 time/week) for 12 weeks. Nutrition education was focused on low energy, high protein and low carbohydrate diet to reduce the body weight and improve the diet quality. To evaluate the effectiveness of the program, daily nutrient intakes were assessed by 24-hour recall method. Body composition, blood lipid profiles and physical fitness test were assessed before and after the intervention. After the intervention, body weight, BMI, percent body fat, soft lean mass and waist/hip ratio were significantly decreased (p < 0.001). Fasting blood sucrose, total cholesterol, LDL-cholesterol and atherogenic index (AI) were significantly decreased (p < 0.001), while HDLcholesterol was significantly increased (p < 0.001). Energy adjusted protein, fiber, vitamin A, vitamin $B_2$, vitamin $B_6$, vitamin C, vitamin E, niacin and folate were significantly increased. After the intervention, the muscle endurance, muscle strength, agility, balance were significantly increased. The changes in obesity indices (body weight, BMI, percent body fat, waist-hip ratio) were correlated with the changes of the nutrient intakes, serum lipid profiles, physical fitness. These results show that nutrition education and exercise program was effective not only for weight reduction but also for the improvement of physical strength and cardiovascular disease risk factors in obese women.
To study effects of methanol extract of prosomillet on lopid metabolism , five groups of male Sprang-Dawley rats weighing 116$\pm$9 g were fed test diets for four weeks. The five diets consisted of one low fat(5% w/w) diet containing starch as carbohydrate source(normal) and four high fat diets(15% w/w) containing 40.5%(w/w)sucrose(control) and additional 80% nethanol extractof prosomillet at the levels of 0.3% and 1%(w/w) or prosomillet powder at the level of 20%(w/w). Serum level of total cholesterol was a little higher but that of triglyceride was 41% lower in 20% (w/w) prosomillet powder group than in the control group. The cholesterol levels of two Liver cholesterol levels were lower and phospolipid levels higher in all three prosomillet powder group . Fecal excretionof bile acid was most increased in the prosomillet powder group among all five test groups. Acitivity of liver microsomal 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase was significantly lower in 0.3% methanol extract fed group than the control and also appeared to be reduced in 1% extract fed one, wherease those of 20 cholesterol 7$\alpha$-hydroxylase were not different among the five groups. Activities of liver cytosilic glucose-6-phosphate dehydrogenase(G6PDH) and malic enzyme were decreased in 0.3% prosomillet methanol extract and 20% powder groups. The results indicate that in addition to fiber, certain active components in prosomillet have potential to exert hypolipidemic effects via regulating hepatic cholesterogenesis and lipogenesis.
The principal objective of this study was to assess the storage characteristics of the maejakgwa to which herb extracts had been added. Moisture was highest in the rosemary sample, and significantly so. Ash and crude fat levels were highest to a significant degree in the olive and rosemary samples. Crude protein was shown to be significantly high in the rosemary and lavender samples. With regard to our mineral analysis, the rosemary sample evidenced the highest mineral levels, at 1,143.6 mg/100g. In the case of rosemary, lavender, thyme, lemon balm and olive-added samples, the Ca, K and P contents were found to be the highest. A total of 16 amino acids was detected. The rosemary sample had the highest levels, at 9,897.8 mg/100g. With regard to free sugar content, glucose, fructose and sucrose levels were significantly higher. As the result of our measurements of the storage period. However, the rising tendency resulted in a significant difference observed 6 days later. When we assessed changes according to the quantity of herbs added, the acid value was shown to be significantly lower in the group with a 2% addition than in the control, which suggested that the storage characteristics in herbs could be enhanced. With regard to the change in TBA, according to the passage of the storage period, the TBA value increased significantly in all the groups with added herbs. When we assessed the changes according to the amount of herbs added, much lower values were observed in the group with addition than the control, which suggests that the storage characteristics could be enhanced by the addition of herbs. In particular, a high level of anti-oxidative activity was observed in the group to which 2% herbs had been added.
BACKGROUND/OBJECTIVES: The primary objective of the treatment of diabetes mellitus is the attainment of glycemic control. Hyperglycemia increases oxidative stress which contributes to the progression of diabetic complications. Thus, the purpose of this study was to investigate the hypoglycemic and antioxidant effects of Daraesoon (Actinidia arguta shoot) in animal models of diabetes mellitus. MATERIALS/METHODS: Rats with streptozotocin-induced diabetes received an oral administration of a starch solution (1 g/kg) either with or without a 70% ethanol extract of Daraesoon (400 mg/kg) or acarbose (40 mg/kg) after an overnight fast and their postprandial blood glucose levels were measured. Five-week-old C57BL/6J mice were fed either a basal or high-fat/high-sucrose (HFHS) diet with or without Daraesoon extract (0.4%) or acarbose (0.04%) for 12 weeks after 1 week of adaptation to determine the effects of the chronic consumption of Daraesoon on fasting hyperglycemia and antioxidant status. RESULTS: Compared to the control group, rats that received Daraesoon extract (400 mg/kg) or acarbose (40 mg/kg) exhibited a significant reduction in the area under the postprandial glucose response curve after the oral ingestion of starch. Additionally, the long-term consumption of Daraesoon extract or acarbose significantly decreased serum glucose and insulin levels as well as small intestinal maltase activity in HFHS-fed mice. Furthermore, the consumption of Daraesoon extract significantly reduced thiobarbituric acid reactive substances and increased glutathione levels in the livers of HFHS-fed mice compared to HFHS-fed mice that did not ingest Daraesoon. CONCLUSIONS: Daraesoon effectively suppressed postprandial hyperglycemia via the inhibition of ${\alpha}$-glucosidase in STZ-induced diabetic rats. Chronic consumption of Daraesoon alleviated fasting hyperglycemia and oxidative stress in mice fed a HFHS diet.

Betaine supplementation has been shown to alleviate altered glucose and lipid metabolism in mice fed a high-fat diet or a high-sucrose diet. We investigated the beneficial effects of betaine in diabetic db/db mice. Alleviation of endoplasmic reticulum (ER) and oxidative stress was also examined in the livers and brains of db/db mice fed a betaine-supplemented diet. Male C57BL/KsJ-db/db mice were fed with or without 1% betaine for 5 wk (referred to as the db/db-betaine group and the db/db group, respectively). Lean non-diabetic db/+ mice were used as the control group. Betaine supplementation significantly alleviated hyperinsulinemia in db/db mice. Betaine reduced hepatic expression of peroxisome proliferator-activated receptor gamma coactivator 1 alpha, a major transcription factor involved in gluconeogenesis. Lower serum triglyceride concentrations were also observed in the db/db-betaine group compared to the db/db group. Betaine supplementation induced hepatic peroxisome proliferator-activated receptor alpha and carnitine palmitoyltransferase 1a mRNA levels, and reduced acetyl-CoA carboxylase activity. Mice fed a betaine-supplemented diet had increased total glutathione concentrations and catalase activity, and reduced lipid peroxidation levels in the liver. Furthermore, betaine also reduced ER stress in liver and brain. c-Jun N-terminal kinase activity and tau hyperphosphorylation levels were lower in db/db mice fed a betaine-supplemented diet, compared to db/db mice. Our findings suggest that betaine improves hyperlipidemia and tau hyperphosphorylation in db/db mice with insulin resistance by alleviating ER and oxidative stress.
