Purpose: Dietary fiber is a component of carbohydrate that is linked closely with the carbohydrate quality, but few studies have investigated the association of high fiber intake with the cardiometabolic risk factors in Koreans. This study examined the association of high fiber and high carbohydrate intake with the cardiometabolic risk factors among Korean adults. Methods: This study included 15,095 adults aged ≥20 years, who participated in the 2013 ~ 2017 KNHANES. The dietary intake was obtained using a 24-h dietary recall method. The associations of high fiber and high carbohydrate intake with metabolic syndrome and dyslipidemia were examined by sex using multiple logistic regression analysis. Results: The median of dietary fiber was 23.6 g/day in men and 20.0 g/day in women. Dietary fiber intake increased gradually as dietary carbohydrate groups increased except for ≥80% of energy from the carbohydrate group. Women in the highest quintile of fiber intake showed a 33% lower risk of metabolic syndrome compared with those in the third quintile. When stratified into low fiber (LF) and high fiber (HF) groups using Adequate Intake of fiber for Koreans, men in the third quartile of carbohydrate intake showed a 44% and 51% higher risk of metabolic syndrome and atherogenic dyslipidemia than in the first quartile, respectively, but only in the LF group. Women in the second quartile of carbohydrate intake showed an 83% higher risk of hypercholesterolemia than in the first quartile in the LF group. On the other hand, as no significant association was observed between the carbohydrate intake and metabolic diseases among the HF groups in both sexes. Conclusion: These findings suggest that a high fiber intake might be associated with a reduced risk of metabolic syndrome and high carbohydrate intake with a low dietary fiber intake might be associated with an increased risk of several metabolic abnormalities among Korean adults. Further prospective studies will be needed to confirm the effects of high fiber and high carbohydrate intake on the cardiometabolic risk factors among Koreans.
The application of polyphenols has attracted great interest in the field of functional foods and nutraceuticals due to their potential health benefits in humans. However, the effectiveness of polyphenols depends on their bioactivity and bioavailability. In the present study, the bioactive component from green tea extract (GTE) was administrated orally (50 mg/kg body weight/day) as free or in a microencapsulated form with maltodextrin in rats fed a high fructose diet. High fructose diet induced features of metabolic syndrome including hypertriglyceridemia, hyperuricemia, increased serum total cholesterol, and retroperitoneal obesity. In addition, myocardial fibrosis was increased. In rats receiving high fructose diet, the lowering of blood triglycerides, total cholesterol, non esterified fatty acid (NEFA) and uric acid, as well as the reduction in final body weight and retroperitoneal fat weight associated with the administration of GTE, led to a reversal of the features of metabolic syndrome (P < 0.05). In particular, the administration of microencapsulated GTE decreased myocardial fibrosis and increased liver catalase activity consistent with a further alleviation of serum NEFA, and hyperuricemia compared to administration of GTE. Taken together, our results suggest that microencapsulation of the bioactive components of GTE might have a protective effect on cardiovasucular system by attenuating the adverse features of myocardial fibrosis, decreasing uric acid levels and increasing hepatic catalase activity effectively by protecting their bioactivities.
Objectives The waist circumference has been known as an obesity index reflecting the visceral fat. This study was conducted to investigate the obesity index of what can be predicted visceral fat obesity. Methods 121 test subjects who have $BMI{\geq}30$ or BMI 27~29.9 with having more than one high blood pressure, diabetes, and hyperlipidemia were gathered in the Gachon University Korean medical hospital.

Objectives: To investigate the effect of a worksite-based dietary intervention program for the management of metabolic syndrome (MS) among male employees. Methods: A dietary intervention program combining individual and environmental approach was implemented targeting white-collar employees at a worksite located in Seoul for 10 weeks. Out of 104 employees having agreed to participate in the program, those having three or more out of five components of MS and having two components, including a waist circumference component were classified into "the high risk group" (n=41) and received group nutrition education and individual nutrition counseling three times each. The rest of the study subjects were considered as "the low risk group" (n=63). The food environment at the worksite, where both the high and low risk groups were exposed, was changed to promote healthy eating. Physical data including MS components were collected and a questionnaire on dietary behaviors was administered before and after the intervention. The data from the high risk group (n=17) and the low risk group (n=20), excluding the subjects ineligible for or failed to complete the study (n=67), were analyzed. The difference before and after intervention was tested for significance by Wilcoxon signed-rank tests. Results: Weight, body mass index (BMI), waist circumference, blood pressure, HDL-cholesterol, and HbA1c and the healthy dietary practice score improved significantly after intervention in the high risk group. The median number of MS components decreased significantly from 3.0 to 1.0 in the high risk group. In the low risk group, only HbA1c significantly decreased. Conclusions: The 10-week worksite-based dietary intervention program combining individual and environmental approach was found to be effective for managing MS of male employees.
The aim of this study was to identify an effective control method of metabolic syndrome (MS) and oral diseases by investigating relationship between of MS and periodontal disease, tooth loss of the adult men and woman. We analyzed and concluded as follows, using a nationwide representative sample, in 8,225 middle senior citizens based on raw data of the 5th National Nutrition Survey in 2010, 2012. The data were analyzed by descriptive statistics, chi-squared test, and logistic regression using SAS ver. 9.2 program. The results are as follows, for correlation of metabolic component to periodontal disease, it was found that in men, the periodontal disease odds ratio of the group with abnormal fasting blood glucose increased 1.27 fold (95% confidence interval [CI], 1.04~1.54), and in woman, the odds ratios of the group with abnormal high density lipoprotein cholesterol increased 1.45 fold (95% CI, 1.22~1.72) and the odds ratio of the group with abnormal obesity increased 1.44 fold (95% CI, 1.17~1.77). For correlation of MS to periodontal disease, it was found that the odds ratio of periodontal disease in the woman at-risk group increased 1.55 fold (95% CI, 1.19~2.01) and that of the group with MS increased 2.25 fold (95% CI, 1.68~3.02). For correlation of woman's metabolic component to missing teeth, it was found that the odds ratio of group with abnormal blood pressure increased 1.41 fold (95% CI, 1.10~1.82). For correlation of woman's MS to missing teeth, it was found that the odds ratio of missing teeth in the group with MS increased 1.48 fold (95% CI, 1.07~2.04). It is considered that a public health project comprising preventive and systematic disease management is necessary for controlling MS and oral disease. The findings of the study are expected to lay the foundation for the development of oral health promotion programs.
High-density lipoprotein (HDL) is a proven biomarker for the monitoring of changes in antioxidant and anti-inflammation capability of body fluids. The beneficial virtues of HDL are highly dependent on its lipids and protein compositions, and their ratios. In normal state, the HDL particle is enriched with lipids and several HDL-associated enzymes, which are responsible for its antioxidant activity. Lower HDL-cholesterol levels (<40 mg/dL) have been recognized as an independent risk factor for coronary artery disease, as well as being a known component of metabolic syndrome. Functional and structural changes of HDL have been recognized as factors pivotal to the evaluation of HDL-quality. In this review, I have elected to focus on the functional and structural correlations of HDL and the roles of HDL-associated apolipoproteins and enzymes. Recent clinical applications of HDL have also been reviewed, particularly the therapeutic targeting of HDL metabolism and reconstituted HDL; these techniques represent promising emerging strategies for the treatment of cardiovascular disease, for drug or gene therapy.
Vitamin D is an essential component of bone and mineral metabolism; its deficiency causes growth retardation and skeletal deformities in children and osteomalacia and osteoporosis in adults. Hypovitaminosis D (vitamin D insufficiency or deficiency) is observed not only in adults but also in infants, children, and adolescents. Previous studies suggest that sufficient serum vitamin D levels should be maintained in order to enhance normal calcification of the growth plate and bone mineralization. Moreover, emerging evidence supports an association between 25-hydroxyvitamin D (25[OH]D) levels and immune function, respiratory diseases, obesity, metabolic syndrome, insulin resistance, infection, allergy, cancers, and cardiovascular diseases in pediatric and adolescent populations. The risk factors for vitamin D insufficiency or deficiency in the pediatric population are season (winter), insufficient time spent outdoors, ethnicity (non-white), older age, more advanced stage of puberty, obesity, low milk consumption, low socioeconomic status, and female gender. It is recommended that all infants, children, and adolescents have a minimum daily intake of 400 IU ($10{\mu}g$) of vitamin D. Since the vitamin D status of the newborn is highly related to maternal vitamin D levels, optimal vitamin D levels in the mother during pregnancy should be maintained. In conclusion, given the important role of vitamin D in childhood health, more time spent in outdoor activity (for sunlight exposure) and vitamin D supplementation may be necessary for optimal health in infants, children, and adolescents.
Diabetic nephropathy (DN) is the leading cause of end-stage renal disease, and its pathogenesis is complex and has not yet been fully elucidated. Abnormal glucose and lipid metabolism is key to understanding the pathogenesis of DN, which can develop in both type 1 and type 2 diabetes. A hallmark of this disease is the accumulation of glucose and lipids in renal cells, resulting in oxidative and endoplasmic reticulum stress, intracellular hypoxia, and inflammation, eventually leading to glomerulosclerosis and interstitial fibrosis. There is a growing body of evidence demonstrating that dysregulation of 50 adenosine monophosphate-activated protein kinase (AMPK), an enzyme that plays a principal role in cell growth and cellular energy homeostasis, in relevant tissues is a key component of the development of metabolic syndrome and type 2 diabetes mellitus; thus, targeting this enzyme may ameliorate some pathologic features of this disease. AMPK regulates the coordination of anabolic processes, with its activation proven to improve glucose and lipid homeostasis in insulin-resistant animal models, as well as demonstrating mitochondrial biogenesis and antitumor activity. In this review, we discuss new findings regarding the role of AMPK in the pathogenesis of DN and offer suggestions for feasible clinical use and future studies of the role of AMPK activators in this disorder.
In order to investigate experimentally the effects of Sung-yangikgibujat'ang (SIT) and Kwangyebujalijungt'ang (KBT) on Yang-insufficient syndrome (陽虛證) induced by Hydrocortisone acetate (H.A.) in experimental animals (Mice and Rat), the author experimented various activities. Delayed type hypersensitivity (DTH), Rosette forming cells (RFC), hemagglutinin (HA) titers, Hemolysin (HL) titers, Body weight, Whole blood viscosity, Plasma Viscosity, Hematocrit, RBC, Albumin, Total protein, Triglyceride, cholesterol and Glucose were measured. The results summerized as follows; 1. In DTH and RFC all the experimental groups were increased significantly in comparison to the H.A.-treated group. 2. In HA titers SIT_treated group were increased significantly and KBT-treated group showed increasing tendancy, but showed no significance. 3. In HL titers all the experimental groups showed increasing tendancy, but showed no significance. 4. In body weight all the experimental groups showed increasing tendancy, but showed no significance. 5. In whole blood viscosity all the experimental groups were decreased significantly in comparison to the H.A.-treated group. 5. In whole blood viscosity all the experimental groups were decreased significantly in comparison to the H.A.-treated group. 6. In plasma viscosity KBT-treated group were decreased significantly and SIT-treated group showed decreasing tendancy, but showed no significance. 7. In Hematocrit SIT-treated group were decreased significantly and KBT-treated group showed decreasing tendancy, but showed no significance. 8. In RBC, albumin and cholesterol all the experimental groups were decreased significantly in comparison to the H.A.-treated group. 9. In total protein and triglyceride KBT-treated group were decreased significantly and SIT-treated group showed decreasing tendancy, but showed no significance. 10. In Glucose SIT-treated group were decreased significantly and KBT-treated group showed decreasing tendancy, but showed no significance. From above findings, it has been demonstrated that Sungyangikgibujat'ang and Kwangyebujalijungt'ang seem to produce the effectiveness on the recovery from depression of the cell-mediated immune response, blood circulation and energy metabolic rate, induced by Hydrocortisone acetate, and in the humoral immune response Sungyangikgibujat'ang have the effectiveness on the recovery, and in cellular component of blood Sungyangikgibujat'ang was more effective than Kwangyebujalijungt' ang, and in plasma of blood Kwangyebujalijungt'ang was more effective than Sungyangikgibujat'ang. Therefore it is suggested that Sungyangikgibujat'ang and Kwangyebujalijungt'ang have the effectiveness on the recovery from Yang-insufficient syndrome more or less.

Impaired glucose tolerance(IGT) & Impaired fasting glucose(IFG) were standardized in 1979 by the National Diabetes Data Group and the World Health Organization as a risk factor for type 2 diabetes. The main clinical significance of IGT & IFG shows some risk factors on type 2 diabetes, cardiovascular disease and component of the metabolic syndrome. In 1997, the American Diabetes Association(ADA) proposed the new classification and diagnostic criteria for diabetes, which wss striction on the diagnostic baseline of Diabetes from 140 mg/dl to 126 mg/dl. This is because that the early diagnosis and treatments can prevent chronic complications. In the oriental medicine, Gamiyookmigihwang-tang has been using for the treatments of Diabetes including IGT & IFG; however, there have not been enough studies about the effect of the glycemic control objectively. So clinical studies have been performed on a mild DM(Diabetes Mellitus) patient with IGT and IFG in order to investigate whether there is hypoglycemic effect of Gamiyookmigihwang-tang. Prior to the study, for two weeks fasting blood sugar(FBS) and postprandial 2hrs(PP2hrs) glucose were checked. in addition ECG, T-cholesterol, TG, HbA1c levels were measured; then, Gamiyookmigihwang-tang has administrated for 4 weeks. and FBS, PP2hrs, T-cholesterol, TG, HbA1c were measured again after the herb medicine treatment. FBS, PP2hrs glucose levels and other measuring levels (T-cholesterol, TG, HbA1c) were decreased by the administration of Gamiyookmigihwang-tang. Gamiyookmigihwang-tang has hypoglycemic effects on a mild DM patient with IGT and IFG.
