Objectives: Previous studies have obtained conflicting findings regarding possible associations between indices measuring carbohydrate intake and dyslipidemia, which is an established risk factor of coronary heart disease. In the present study, we examined crosssectional associations between carbohydrate indices, including the dietary glycemic index (GI), glycemic load (GL), total amount of carbohydrates, and the percentage of energy from carbohydrates, and a range of blood lipid parameters. Methods: This study included 1530 participants (554 men and 976 women) from 246 families within the Healthy Twin Study. We analyzed the associations using a generalized linear mixed model to control for familial relationships. Results: Levels of the Apo B were inversely associated with dietary GI, GL, and the amount of carbohydrate intake for men, but these relationships were not significant when fat-adjusted values of the carbohydrate indices were used. Triglyceride levels were positively associated with dietary GI and GL in women, and this pattern was more notable in overweight participants (body mass index [BMI] ${\geq}25kg/m^2$). However, total, low-density lipoprotein and high-density lipoprotein cholesterol levels were not significantly related with carbohydrate intake overall. Conclusions: Of the blood lipid parameters we investigated, only triglyceride levels were positively related with dietary carbohydrate indices among women participants in the Healthy Twin Study, with an interactive role observed for BMI. However, these associations were not observed in men, suggesting that the association between blood lipid levels and carbohydrate intake depends on the type of lipid, specific carbohydrate indices, gender, and BMI.
The purpose of this study was to investigate the effect of soybean on blood glucose and lipid concentrations, and antioxidant enzyme activity in type 2 diabetes mellitus(DM) patients. We divided patients into two groups and fed them, respectively, a basal diet(control group) and a basal diet with 69 g/d of soybean(soybean group) for 4 weeks. Pills with roasted soybean powder were provided to the soybean supplementation group three times a day. Macronutrients intake except dietary fiber was similar between the two groups. No significant differences were observed in dietary intakes or body weight before and after the supplementation. Energy composition ratio of C:F:P was 65:19:16 in the control group, 64:20:16 in the soybean group. The blood parameters of subjects before supplementation, such as fasting blood glucose, postprandial glucose level, total cholesterol, triglyceride, LDL-cholesterol and $HbA_1C$ were not different between the two groups. After supplementation, fasting blood glucose(p<0.001), postprandial glucose level(p<0.001) and serum triglyceride level(p<0.05) were significantly reduced in the soybean group in comparison with the control group. The total cholesterol level was not significantly different between the control and the supplemented group after 4 weeks of treatment. TBARS levels of the soybean group were not significantly different from those of the control group. The activities of catalase(p<0.01) and glutathione peroxidase(p<0.05) were significantly higher in the soybean group compared to the control group. The results of this study suggest that soybean supplementation would be helpful to control blood glucose and serum lipid in diabetic patients. Also, soybean showed an antioxidant activity that may contribute to enhance the effect of antioxidant defense. This activity contributes to protection against oxidative damage in type 2 DM patients. Soybean may have potential use in the disease management of patients with DM.

Type 2 diabetes mellitus (T2DM) is characterized by hyperglycemia and dyslipidemia. Carvacrol (CAR) has demonstrated the potential to mitigate dyslipidemia. This study aims to investigate whether CAR can modulate blood glucose and lipid levels in a T2DM rat model by regulating short-chain fatty acids (SCFAs) and the GPR41/43 pathway. The T2DM rat model was induced by a high-fat diet combined with low-dose streptozocin injection and treated with oral CAR and/or mixed antibiotics. Fasting blood glucose, oral glucose tolerance, and insulin tolerance tests were assessed. Serum lipid parameters, hepatic and renal function indicators, tissue morphology, and SCFAs were measured. In vitro, high glucose (HG)-induced IEC-6 cells were treated with CAR, and optimal CAR concentration was determined. HG-induced IEC-6 cells were treated with SCFAs or/and GPR41/43 agonists. CAR significantly reduced blood lipid and glucose levels, improved tissue damage, and increased SCFA levels in feces and GPR41/43 expression in colonic tissues of T2DM rats. CAR also attenuated HG-induced apoptosis of IEC-6 cells and enhanced GPR41/43 expression. Overall, these findings suggest that CAR alleviates blood lipid and glucose abnormalities in T2DM rats by modulating SCFAs and the GPR41/43 pathway.
Interactive effects among eating behavior, obesity and serum lipid levels were studied in 117, 4~12 year old children residing suburban Seoul. Fasting blood samples are obtained and analyzed for serum triglycerides (TG), total cholesterol(TC), high density lipoprotein-cholesterol(HDL-C) and hematochrit. Obesity was determined by weight for length index(WLI)and the information on eating behavior including food habits and dietary intakes was obtained by questionaire using food record method for 2-consecutive days. Over 40% of children was classified overweight or obese by WIL and children's physical parameters were closely related to those of parents implying genetic influence on obesity. Although it did not reach the statistical significance, there was a tendency of higher TG, TC and low density lipoprotein-cholesterol(LDL-C)levels among girls compared to boys. Blood lipid levels of obese children were similar to those of other groups except TG, which was significantly higher(p<0.05) in obese group. Nutrient intakes seemed adequate in all subjects except iron, calcium and total calorie which were lower than RDAs. Lacking significant relationship between individual nutrient intake and obesity, there was significant correlation between food intake and blood lipid level especially in 10-12 year old group. Vegetable intake was negatively related to TG, LPH(LDL-C/HDL-C) and atherogenic index(AI), and positively to HDL-C. Skipping breakfast and frequent eating out appeared to cause imbalances in nutrient intake. These findings clearly revealed the influence of eating behavior on childhood obesity along with blood lipid profile. To ensure the proper growth and health of these children, devising method and developing media for nutrition education suited to our society should be accomplished first. With well-planned nutrition surveys and thorough intention, childhool obesity could be prevented from progress into adulthood obesity.
Ssireum, the traditional Korean sport, is very popular at both amateur and professional levels. Ssireum players are prone to be obese which related to the chronic disease in their later life. The purpose of the study was to compare the anthropometric measurements, quality of diet, and blood parameters of Ssireum players with those of subjects who were matched body mass index, gender and age. Participants in the 3 groups, Ssireum players (SP, n=15), regular moderate exerciser (RME, n=15, >3 times /wk, >20 min/time) and intermittent light exerciser (ILE, n=14) groups. Anthropometric measurements included height, weight, fat mass (by Dual energy X-ray absorptiometry), lean body mass, triceps and thigh skin-fold thickness, mid-arm, waist, hip and thigh circumference. Dietary assessments were accomplished using 3-days food records, diet quality index (DQI), dietary variety score (DVS). Blood levels of lipids, leptin and insulin were analyzed. As a results lean body mass and mid-arm circumference were significantly higher in Ssireum players than those of other groups (p<0.01). Total body fat, trunk fat, abdominal skin fold thickness and waist-hip ratio were significantly lower in SP group than those of other groups (p<0.01). DVS were higher however, dietary quality was low in Ssireum players than in other groups. There were no differences among the 3 groups in regard to blood total cholesterol, LDL-cholesterol and glucose levels however, leptin level was low in Ssireum players. These results indicate that Ssireum players had significantly higher lean body mess and lower body fat when these were compared with regular moderate exerciser and intermittent light exerciser. Blood leptin levels of Ssireum players were low but blood lipid profiles were not significantly different.
Effects of Bupleuri Radix, Paeonie Radix or Uncariae Ramulus et rncus on experimental yperlipidemia were studied. Hyperlipidemia was induced on male Wistar rats by feeding them on high holesterol diet for one week, as previously described by the authors. Blood lipid profile was verified on these ats by measuring total cholesterol(TC), triglyceride(TG), high density lipoprotein cholesterol(HDL) and low ensity lipoprotein cholesterol(LDL). Then, the rats were followed by feeding normal diet. At the same time, ethanol extracts of the three individual herb medicines were orally administered to the rats for 4 weeks and the parameters above mentioned were monitored. Methanol extract of 5Bupleuri radix reduced the TC value significantly at 2 week point and Paeoneae Radix reduced the TC value at 4 week point in compare to control group, suggesting the antihyperlipidemic effect of the two herbal medicines in vivo. The extract of Uncariae Ramulus et Uncus however did not show antihyperlipidemic effect in our experiment.
This study was performed to investigate the effects of alcohol drinking frequency and foods consumed along with alcohol on anthropometry, serum lipid levels, and blood pressures in 73 male type 2 diabetic patients aged 30-59 years old. Dietary data for usual intake were obtained from the subjects by the 3-day food records. Separate data for foods consumed along with alcohol as accompaniment were collected and analyzed for energy and nutrient intakes. Both alcohol drinking frequency and/or the amount of energy consumed from accompaniment influenced clinical data as well as anthropometric measurements. The serum total- and HDL-cholesterol, triglyceride levels and systolic blood pressure were significantly higher in the group with a drinking frequency of ${\geq}$ 2/week than that of ${\leq}$ 1/week and also in the group whose daily energy intake from accompaniment was greater than the median (106.6 kcal/d) than that below the median. When the data were adjusted for age, amount of energy intake from alcohol and diet, the anothropometric measurements such as body weight, BMI, waist circumference were significantly higher in patients whose energy intake from accompaniment was greater than the median than that below the median. The results of our study suggest that both alcohol drinking frequency and the energy intake from foods consumed along with alcohol as accompanements are important contributing factors to clinical and anthropometric parameters whose associations with the cardiovascular complications are well established in patients with diabetes mellitus.
Dietary nitrate supplementation from green leafy vegetables and beetroot is involved in the 'nitrate-nitrite-nitric oxide (NO) pathway' and is reported to have important vascular impacts. This study evaluated the blood parameters and blood flow change subsequent to a raw juice diet program. The 28 subjects who voluntarily participated in the raw juice diet program at Sahmyook University were instructed to drink the juice composed of fruits and vegetables instead of partaking the usual meal, at a scheduled time daily. The study was approved by the research ethics council of the Sahmyook University (SYUIRB 2014-043). Evaluation of the participants after the required duration revealed decreased levels of soft lean mass (P<0.05), skeletal muscle mass (P<0.001), body fat mass (P<0.001), body mass index (P<0.001) and circulating levels of total cholesterol (P<0.001), triglycerides (P<0.05), HDL-cholesterol (P<0.01), LDL-cholesterol (P<0.01), and blood urea nitrogen (P<0.001). Conversely, circulating levels of creatinine (P<0.001), hemoglobin (P<0.001), and hematocrit (P<0.01) were increased after the intervention. The blood flow levels were also increased after the program (P<0.001). Our results indicate that a short-term raw juice diet contributes to the improvement of vascular blood flow and blood lipid parameters, and decreases the lean muscle mass related to dehydration.
We investigated the pathogenesis of liver tissue damage during the lipid peroxidation and fibrogenesis with the observation of correlations between the parameters of collagen synthesis (and deposition) and lipid peroxidation in liver fibrosis (cirrhosis) rats. Rats were randomly divided into two groups, normal and $CCl_4$-thiopental sod. intoxicated group. And the one group was treated intragastrically with the mixture of $CCl_4$-thiopental sod. 3 times per week for 3 weeks. The liver tissue and sera were used for the measurement of hydroxyproline (HYP), malonedialdehyde (MDA) and superoxide dismutase (SOD). Biochemical parameters such as aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), total-bilirubin and blood urea nitrogen (BUN) were measured. Additionally, the expression of collagen ${\alpha}1$(III) and $\beta$-actin mRNA was observed by RTPCR. The histological change in liver tissue was also observed by Masson's trichrome and H&E staining. Correlation analysis was carried by Spearman's rho method. All biochemical parameters except total-bilirubin were significantly higher in the $CCl_4$-thiopental sod. treated group than that of the normal group (p < 0.01). In the $CCl_4$-thiopental sod. treated group, Hyp as a parameter of collagen synthesis (deposition) and MDA as a metabolite of lipid peroxidation, were significantly elevated by 1.98 and 2.11 times higher than that of the normal group (p < 0.001) respectively. The activity of SOD in the $CCl_4$-thiopental sod. treated group is decreased significantly by 44.8% (p < 0.001). And collagen ${\alpha}1$(III) mRNA was more expressed in the $CCl_4$-thiopental sod. treated group than that of the normal group. However, the expression of $\beta$-actin mRNA is showed similar in both of groups. A good correlation was observed between the content of hyp and MDA concentration (r = 0.70, n = 40) in the two groups. And the correlation between the levels of hyp and SOD (r = -0.71, n = 25) is also reliable. However, no correlation were observed between MDA concentration and SOD (r = -0.40, n = 25) in the two groups. Elevated levels of MDA in $CCl_4$-thiopental sod. treated rats indicated enhancement of lipid peroxidation, which is accompanied by a decrease in SOD activity. Moreover, we could confirm that the parameters of collagen synthesis (and deposition) is in good correlation with the metabolite of lipid peroxidation (MDA) and the lipid peroxidation antagonizing enzyme (SOD). Hence, we propose that (1) lipid peroxidation and collagen synthesis (and deposition) could be enhanced by intragastrically application of $CCl_4$-thiopental sod. during a short terms. And (2) the intoxication of $CCl_4$-thiopental sod. could be used for monitoring of lipid peroxidation and collagen synthesis (and deposition) for test of antioxidant and antifibrotic agent.
Several studies revealed that low calcium intake is related to high prevalence of cardiovascular diseases such as hypertension. The prevalence of hypertension is high in Koreans along with their low dietary calcium consumption. Thus, the aim of this study was to evaluate the status of calcium intake between the hypertension and normotension groups and to investigate the correlation between dietary calcium intake and blood pressure, blood lipid parameters, and blood/urine oxidative stress indices. A total of 166 adult subjects participated in this study and were assigned to one of two study groups: a hypertension group (n = 83) who had 140 mmHg or higher in systolic blood pressure (SBP) or 90 mmHg or higher in diastolic blood pressure (DBP), and an age- and sex-matched normotension group (n = 83, 120 mmHg or less SBP and 80 mmHg or less DBP). The hypertension group consumed 360.5 mg calcium per day, which was lower than that of the normotension group (429.9 mg) but not showing significant difference. In the hypertension group, DBP had a significant negative correlation with plant calcium (P < 0.01) after adjusting for age, gender, body mass index (BMI), and energy intake. In the normotension group, total calcium and animal calcium intake were significantly and positively correlated with serum triglycerides. No significant relationship was found between calcium intake and blood/urine oxidative stress indices in both groups. Overall, these data suggest reconsideration of food sources for calcium consumption in management of the blood pressure or blood lipid profiles in both hypertensive and normotensive subjects.
