The purpose of this study was to determine changes in body composition and blood lipids and to analyze the effects of Danhak exercise for 3 months in older women. For this study, 35 female subjects 60 to 70 years of age were recruited and administered 90 min of Danhak exercise, five times per week for three months by a professional coach. The results of this study were as follows: At baseline, the mean BMI(body mass index) and body fat(%) were 23.9 kg/$(m)^2$ and 32.4$\pm$4.9(%), respectively. The mean WHR(waist-hip ratio) was 0.91$\pm$0.04 and all subjects were determined to be abdominally obese. A significantly lower body fat was observed after 3 months of Danhak exercise(p<0.05). However, there were no significant differences in BMI, WHR or body weight before and after exercise. Danhak exercise also resulted in a decrease in total cholesterol and an increase in HDL(high density lipoprotein, and these differences were significant. Taken together, the results of this study indicate that the effects of Danhak exercise were similar to those of aerobic exercise with respect to improve body fat(%) and blood lipid profiles, which suggests that Danhak is a profitable exercise for individuals aged 60 and over.

The purpose of this study was to investigate the effects of dietary Chungkookjang (Korean fermented soybean) powder on blood glucose level, lipid profiles, antioxidant enzymes activities and histological changes in kidney of streptozotocin (STZ)-induced diabetic rats. Male Sprague-Dawley rats of three groups including nondiabetic group fed normal diet (NC), diabetic group fed normal diet (DC) and diabetic group fed Chungkookjang diet (DCH; 100 g/kg diet) were reared for 8 weeks. The serum glucose, triglycelide and total lipid levels in the DCH group were significantly lower (P<0.05) than the DC group. The renal xanthine oxidase, catalase and glutathione S-transferase activities in the DC group were significantly higher than the NC group. The xanthine oxidase, superoxide dismutase and glutathione S-transferase activities in the DCH group were significantly lower than the DC group (P<0.05). Tubular epithelial change, such as Armanni-Ebstein cells, was significantly reduced in the DCH group compared to the DC group. In conclusion, these results indicated that Chungkookjang supplement seems to be beneficial to correct the hyperglycemia and hyperlipidemia as well as to protect kidney against diabetic changes.

Epidemiological studies have indicated that a relationship between overweight and cardiovascular disease exists. To assess the relationship of unfavorable changes in serum lipid concentrations, apolipoprotein B, lipoprotein(a), blood sugar and blood pressure to anthropometric variables, nutrient intakes and dietary behavior,64 obese children were chosen as subjects and 24-hour dietary intake, dietary behavior as well as blood pressure, apolipoprotein B, lipoprotein(a), three kinds of cholesterol concentrations were measured in November 1976. More than half(57.8%) of the children had serum cholesterol concentrations over 175mg/d1, and 26.6% of them had over 200mg/d1 and this group could be classified as a high risk group. Abdominal obesity as measured with waist circumference and waist hip ratio was negatively co..elated to high density lipop개tein(HDL) cholesterol. Dietary behavior rather than nutrient intakes appeared to have associations with unfavorable lipid profiles. Total dietary behavior scores and fish and bean product consumption had strong correlations with potentially atherogenic lipoprotein concentrations. This study suggests that fir the early prevention of cardiovascular disease, waist hip ratio together with obese rate should be included in selective programs to identify risk group of children in Korea. furthermore, interventions in cardiovascular disease risk groups in obese children should emphasize maintenance of ideal body weight through reducing body fat and adopting desirable dietary behaviors such as increasing intake of fish or bean products.

Purpose: Gardening has been reported to have positive emotional and physical effects in older adults. However, limited studies have assessed this relationship in Korea. Therefore, in this pilot study of densely populated urban dwellers, we aimed to investigate whether temporary but repeated experiences of the natural environment could positively change metabolism-related blood indicators. Methods: This study used pre- and post-interventional designs to investigate the effects of 16 weeks of gardening on lipid profiles in an urban adult population and investigate their relationships. This study was conducted 30 times at the H Botanical Garden in Yongin City from August 16, 2021 to November 30, 2021 (16 weeks, twice a week, 3 hours each time). Before and after the gardening program, a clinical pathologist collected blood samples from the participants. Results: High-density lipoprotein levels increased, low-density lipoprotein levels decreased, and total cholesterol levels decreased after the gardening activity. Conclusions: Our findings suggest that gardening has potential for clinical application as it has good control over the lipid profile through physical activity. These findings can be used as basic data for studying the relationship between urban populations and their living environment and for various studies in the future as experiencing the natural environment provides many health benefits.

This study was designed to evaluate antihyperglycemic and antihyperlipidemic effects of ethanol extracts of Taraxacum mongolicum(T.m.) on streptozotocin (STZ)-induced diabetic rats. Sprague-Dawley rats were randomly assigned to five groups: normal (NC), STZ-control (DC), and three experimental groups. Diabetes was induced in Sprague-Dawley rats with a single intravenous injection [45 mg/kg body weight (b.w.)] of STZ. An ethanol extract of T.m. was orally given to diabetic rats for 14 days. Three experimental groups were additionally treated with T.m. extract at doses of 1 g/kg b.w./day for T.m.-1, 2 g/kg b.w./day for T.m.-2, and 3 g/kg b.w./day for T.m.-3. Oral administration of T.m.-2 significantly increased their body weights. T.m.-1 and T.m.-2 significantly decreased aspartate aminotransferase (AST) levels than DC. T.m.-1 and T.m.-2 group significantly decreased blood glucose levels. Total cholesterol, triglycerides, and free fatty acids were significantly decreased whereas high-density lipoprotein cholesterol was significantly increased in groups treated with T.m. extract than those in the DC group. These results support the fact that administration of T.m. extract can reduce hyperglycemia and hyperlipidemia risk in diabetic rats.

비만 남자 초등학생을 대상으로 식사 조절과 병행한 유산 소운동을 HRmax의 60-70% 강도로 1일 100분, 주 5회, 9주간 실시하여 이들의 혈중지질과 아포지단백에 미치는 효과에 대해 알아보았다. 혈중지질의 TC, TG, HDL-C 농도와 TC/ HDL-C비가 개선되었는데 이는 규칙적인 유산소운동과 에너지섭취량 제한(식사제한)이 아닌 1일 영양권장량에 준하는 정상적인 에너지 섭취를 통해 비만아동의 체중감량과 더불어 CHD 위험인자인 혈중지질에 긍정적인 효과를 미칠 수 있음을 확인하였다. 또한 아포지단백의 Apo AII, B, CIII 농도가 감소하였는데 이는 유산소운동과 식사조절 병행이 성인의 경우와 유사하게 비만 남자아동들에게도 동맥경화 질환의 예방에 효과적인 방법이 될 수 있음을 증명하는 결과로 사료된다. 그렇지만 아직 운동에 따른 Apo 반응에 대한 연구들이 미흡하고 특히 Apo CII와 CIII에 대한 연구는 더욱 미흡한 상황이므로 향후 이에 관련된 후속 연구가 진행되어야할 것으로 생각된다.

The purpose of this study was to investigate the distribution patterns of serum triglyceride and cholesterol levels and the influence of environmental and dietary factors in 201 healthy male subjects. The subjects were found to be 53.7% for the normal, 15.4% for the TC, 17.4% for TG and 13.5% for TC.TG group, respectively. Among general characteristics, smoking significantly affected serum lipid levels of subjects (p < 0.05). Among anthropometric factors, body weight, BMI and PIBW significantly influenced the blood lipid patterns. Body weight of TG group was significantly higher than that of normal group (p < 0.05). BMI and PIBW of TG group and TC.TG group were significantly higher than those of normal group (p < 0.05) . In addition, diastolic blood pressure of TG group was significantly higher than that of normal group (p < 0.05). For the food intake, average intake of fruit was significantly higher in normal group than that of TG group (p < 0.05). For nutrient intake, calcium intake was significantly higher in TC group than those of normal and TC.TG group (p <0.05). Intakes of vitamin $B_2$ and C were significantly higher in TC group than those of in TG group (p < 0.05). Serum HDL-cholesterol level was negatively related to meat, poultry, and their products (p <0.05), but serum total cholesterol level positively related to animal lipids (p < 0.05). The results of this study suggest that it is crucial for maintaining adequate serum lipid levels to reduce smoking, blood pressure and to lose body weight. As far as food intake concerned, fruit intake was important in maintaining serum triglyceride level normal, while animal food intake affected serum total cholesterol level adversely.

BACKGROUND/OBJECTIVES: Timing of almond intake during a day may result differently in the perspectives of body composition and changes of lipid profile. The current study was conducted to compare the effects of daily almond intake as a preload versus as a snack on body composition, blood lipid profile, and oxidative and inflammation indicators among young Korean adults aged 20-39 years old. SUBJECTS/METHODS: Participants were randomly assigned to one of three groups: a pre-meal almond group (PM), a snack almond group (SN) in which participants were instructed to consume 56 g of almonds either as a preload before meals or as a snack between meals, respectively, and a control group (CL) in which participants were provided high-carbohydrate iso-caloric control food. Measurements were performed at baseline, weeks 8 and 16. RESULTS: A total of 169 (M 77 / F 92) out of the 227 participants completed the study between June 2014 and June 2015 (n = 58 for PM; 55 for SN; and 56 for CL). A significant decrease in body fat mass was observed in the PM group at both weeks 8 and 16 compared with the CL. There were significant intervention effects on changes of body fat mass (P = 0.025), body fat percentages (P = 0.019), and visceral fat levels (P < 0.001). Consuming almonds as a daily snack reduced the levels of total cholesterol (P = 0.043) and low-density lipoprotein (LDL) cholesterol (P = 0.011) without changing high-density lipoprotein (HDL) cholesterol compared with the CL. CONCLUSION: Almond consumption as a preload modified body fat percentages, whereas snacking on almonds between meals improved blood lipid profiles. This trial was registered at ClinicalTrials.gov as NCT03014531.

Spirulina is a microscopic and filamentous cyanobacterium that contains essential amino acids, essential fatty acids, vitamins, minerals and anti-oxidative components. The purpose of this study was to examine effects of spirulina intervention in Korean patients with type 2 diabetes. The subjects were 37 type 2 diabetic patients who visited a diabetic clinic in Seoul and randomly assigned into spirulina (8 g/day) or control group. During the intervention period of 12 weeks, subjects were asked to keep usual diet and prohibited to take any functional foods or dietary supplements. Spirulina supplementation for 12 weeks did not affect anthropometric parameters, however, lowered plasma triglycerides level significantly (p<0.05). Spirulina supplementation also resulted in a significant reduction in plasma malondialdehyde level (p<0.05) and an increase in plasma adiponectin level (p<0.1). The lipid lowering effect of spirulina supplementation was different according to serum lipid levels of the subjects before entering the intervention. The subjects with higher initial triglyceride level showed higher reduction in plasma triglyceride and blood pressure. The subjects with higher initial total cholesterol and LDL-cholesterol level showed higher reduction in plasma concentrations of total cholesterol, LDL-cholesterol, IL-6, and blood pressure. It seems that spirulina supplementation is more effective in subjects with dyslipidemia. This study provides the evidence for beneficial effects of spirulina supplementation on blood lipid profiles, inflammatory variables, and antioxidant capacity in Korean patients with type 2 diabetes. The results suggest that spirulina is a promising agent as a functional food for diabetes management.
