Milk Minerals

Despite a high content of saturated fat, evidence from observational studies indicates that the consumption of dairy products may have a neutral effect or may be inversely associated with the risk of CVD. We aimed to examine whether milk minerals modify the effect of saturated fat on serum lipid profile. We present data from two studies. Study I had a randomised, blinded, parallel design (n 24 pigs) with a 10 d adaptation period during which a high-fat diet was fed to the pigs and a 14 d intervention period during which the same diet either enriched with milk minerals (MM group) or placebo (control group) was fed to the pigs. Study II had a randomised cross-over design (n 9 men) where the subjects were fed either a high-fat diet enriched with milk minerals (MM period) or a regular diet (control period). In both the studies, blood variables were measured before and after the intervention and faecal and urine samples were collected at the end of the dietary periods. The increase in plasma total cholesterol and LDL-cholesterol concentrations but not in HDL-cholesterol concentration was markedly lowered by milk minerals in both the studies. In the animal study, baseline adjusted total cholesterol and LDL-cholesterol concentrations in the MM group were 11 % (P= 0·004) and 13 % (P= 0·03) lower compared with those in the control group after the intervention. Similarly in the human study, baseline adjusted total cholesterol and LDL-cholesterol concentrations were 6 % (P= 0·002) and 9 % (P= 0·03) lower after the MM period compared with those in the control period. HDL-cholesterol concentration was not lowered by milk minerals. These short-term studies indicate that the addition of milk minerals to a high-fat diet to some extent attenuates the increase in total cholesterol and LDL-cholesterol concentrations, without affecting HDL-cholesterol concentration.

This study examined the effect of a Du-zhong (Eucommia ulmoides Oliver) leaf extract (0.175 g/100 g diet) that was supplemented with a high-fat diet (10% coconut oil, 0.2% cholesterol, wt/wt) on hyperlipidemic hamsters. Hamsters fed with Du-zhong leaf extract for 10 weeks showed a smaller size of epididymal adipocytes compared to the control group. The supplementation of the Du-zhong leaf extract significantly lowered the plasma levels of triglyceride, total cholesterol, LDL-cholesterol, non HDL-cholesterol, and free fatty acid, whereas it elevated the HDL-cholesterol/total cholesterol ratio and apolipoprotein A-I levels. The hepatic cholesterol concentration was lower in the Du-zhong group than in the control group. The plasma total cholesterol concentration was positively correlated with hepatic HMG- CoA reductase activity (r = 0.547, p < 0.05) and hepatic cholesterol concentration (r = 0.769, p < 0.001). The hepatic fatty acid synthase and HMG- CoA reductase activities were significantly lowered by a Du-zhong leaf extract supplement in high fat-fed hamsters. Hepatic fatty acid synthase activity was positively correlated with plasma fatty acid concentration (r = 0.513, p < 0.05) that was lower in the Du-zhong group. These results demonstrate that the Du-zhong leaf extract exhibits antihyperlipidemic properties by suppressing hepatic fatty acid and cholesterol biosynthesis with the simultaneous reduction of plasma and hepatic lipids in high fat-fed hamsters.

Introduction: Dyslipidemia is a major risk factor of coronary artery disease (CAD), and is affected by interaction between genetic and environmental factors, such as diets. Weight-loss diet intervention has been widely used to improve lipids to mitigate cardiovascular complications of obesity. Hypothesis: We hypothesize that the genetic predisposition to CAD may modify lipids metabolism in response to diets. Methods: We calculated a genetic risk score (GRS) based on 19 CAD-associated single nucleotide polymorphisms in 744 adults from a 2-year diet intervention study: the POUNDS Lost trial. We examined the changes in total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol and triglycerides by the GRS and diet intervention. Results and Conclusions: We found significant interaction between the GRS and dietary fat intake on changes in total cholesterol, HDL and LDL cholesterol (P-interaction=0.02, 0.01 and 0.02, respectively) after the 2-year intervention. Overall, both low- and high-fat diets decreased total cholesterol, LDL cholesterol and triglycerides, but increased HDL cholesterol. At 2 years, in the highest tertile of the GRS, participants eating the low-fat diet showed a greater decrease in total cholesterol and LDL cholesterol than those eating the high-fat diet; whereas participants eating the high-fat diet showed a greater increase in HDL cholesterol than those eating the low-fat diet (all P<0.001). In lower tertiles of the GRS, the difference in lipids changes between the two diet groups was not significant. In conclusion, genetic predisposition to CAD might modify the dietary fat induced lipids changes. Our data suggest that in participants with higher genetic risk, low-fat diet may lower total cholesterol and LDL cholesterol, while high-fat diet may improve HDL cholesterol. And in participants with lower genetic risk, the two diets showed similar effects on improvement of lipid profile.

Diets included high-fat (HFD) and high calories intake is correlated with greater risk of obesity and oxidative stress, which lead to increase the risk of related diseases such as cardiovascular and metabolic disease. In the present study, we have examined the hypolipidemic activity of Hypericum Scabrum extract on HFD fed rats. Fifty-four male Wistar rats divided into six groups: 1) control, 2) H. Scabrum extract (100 mg/kg gavage per day), 3) H. Scabrum extract (300 mg/kg), 4) HFD, 5) HFD and H. Scabrum extract (100 mg/kg), 6) HFD and H. Scabrum extract (300 mg/kg). The groups were fed their diet and treatment for 3 months. Biochemical analysis showed elevated lipid serum profile in HFD rats compared to control group. H. Scabrum extract supplementation significantly ameliorated triglyceride, total cholesterol and LDL-cholesterol. H. Scabrum extract supplementation leading to increase HDL-cholesterol in HFD treated groups. This experiment showed that H. Scabrum extract decreased HFD complications and might be beneficial herbal drug for treatment of hyperlipidemia and obesity.

The Saesaengmyung Diet (SD) is a newly developed dietary product to help control weight. The aim of this study was to evaluate whether SD combined with a high-fat (HF) diet could influence body weight, fat accumulation, and glucose levels in blood. C57BL/6J mice were fed for 8 weeks with a standard diet, an HF diet, and an HF + 10% or HF + 20% SD diet. Body weight was recorded weekly, and plasma levels of total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and glucose were analyzed at the end of the study. Weight increases in the 10% or 20% SD group were significantly less than in the HF diet group (p < 0.05). Plasma total cholesterol level significantly decreased by 33.5% in the 10% SD group and 38.8% in the 20% SD group, but the LDL cholesterol, HDL cholesterol, and glucose levels in the SD groups were not significantly changed. Our findings indicate that SD may be beneficial to overweight individuals in the reduction of weight gain induced by an HF diet.Key words: Saesaengmyung Diet, high-fat diet, obesity, body weight, cholesterol, glucose.

Substitution of dietary saturated fat by unsaturated fat and the reduction of dietary cholesterol intake leads to a decrease of LDL cholesterol concentration accompanied usually by a decrease of HDL cholesterol. Method: 18 young male volunteers were fed for 4 weeks either a high cholesterol saturated fat diet or low cholesterol and unsaturated fat diet in crossover design. At the end of both experimental periods, the lipoprotein concentration was determined. In addition, the reverse cholesterol transport from 14 C cholesterol labeled macrophages in tissue cultures was analyzed. Reverse cholesterol transport was calculated as the percentage of radioactivity released from pre-labeled cells to incubation media with serum of each individuals. Results: Highly significant decrease of LDL cholesterol after the unsaturated fat diet was accompanied by a significant decrease of the HDL cholesterol from 1.25 mmol/l to 1.05 mmol/l. Reverse cholesterol transport did not significantly change when the data of high cholesterol saturated fat diet (9.97 ± 1.45) and low cholesterol unsaturated fat diet (9.53 ± 1.41) were compared. There was no correlation between data of the decrease of HDL cholesterol concentration and change in reverse cholesterol transport. Conclusion: We conclude that dietary treatment by hypocholesterolemic diet accompanied by a reduction of HDL cholesterol does not lead to the decrease in reverse cholesterol transport.

Abstract Objectives The study was aimed at assessing the effects of Lactobacillus rhamnosus yoba on the serum lipid profile and body weight of male Wistar rats fed a high fat diet. Methods 20 seven week old male rats weighing between 120 g and 180 g were used for the study and divided into 4 groups of 5 rats each. The control group was fed normal mice pellets and distilled water, while the other groups were fed mice pellets supplemented with 3% cholesterol and 2% saturated fat in addition to any of distilled water, Lactobacillus rhamnosus yoba or Norvastatin respectively. The body weight was measured at the start of the study and after 2 weeks while serum parameters were measured after 8 weeks. Data was analyzed using SPSS Version 20. ANOVA and Tukey's tests determined significant differences in means at 95% confidence interval. Results Lactobacillus rhamnosus yoba significantly (P < 0.005) modulated weight gain, serum total cholesterol and triglycerides when compared to the control. Similarly, LDL-cholesterol was significantly modulated (P < 0.005) while HDL-cholesterol was significantly enhanced (P < 0.005) when compared to the control. Conclusions The ability of Lactobacillus rhamnosus yoba to elevate HDL cholesterol and modulate LDL-cholesterol without the side effects of statins makes it a potential functional food. In line with the findings, the present study justifies the use of Lactobacillus rhamnosus yoba as a probiotic in fermented foods. Funding Sources NA.

Hyperlipidaemia is a well documented risk factor for cardiovascular disease, a major cause of mortality world-wide. Chrysophyllum albidum (white star apple) has several medicinal properties.  Ingestion of the fruits has been found to lower lipid levels in the body, due to its high fibre content. Research works have shown that several parts of the plant are highly medicinal. The aim of this study was to evaluate the antihyperlipidaemic property of methanol leaf extract of Chrysophyllum albidum in Wistar rats fed with a high fat diet. Thirty male Wistar rats weighing between 130g-150g were distributed into five groups of six animals each. Group 1 received normal fat diet (NFD). Group 2 received high fat diet (HFD; Grower mash supplemented with 20% beef tallow). Group 3 received HFD and a standard lipid lowering drug, orlistat (20mg/kg body weight, p.o).  Animals in group 4 and 5 were fed on HFD and received methanol leaf extract of Chrysophyllum albidum, 250mg/kg and 500mg/kg, p.o respectively. The administration was carried out for 56 days. On the 57th day, animals were sacrificed by cervical dislocation. Organs were harvested and blood samples were collected for biochemical analyses. Results showed that the administration of HFD increased the total cholesterol, LDL-Cholesterol, triglycerides levels and decreased the HDL- cholesterol levels significantly (p <0.05). Simultaneous administration of Chrysophyllum albidum extract significantly (p<0.05) reduced the total cholesterol, LDL-Cholesterol, triglycerides levels and increased HDL- Cholesterol. Final body weights of animals that received Chrysophyllum albidum extract were significantly (p<0.05) lower than final body weights of animals in groups 2 (negative control). Results from Histopathology revealed inflammation of the liver and kidney of rats in group 2 (negative control). On the other hand, rats that received orlistat and Chrysophyllum albidum extract had normal liver and kidney architecture. It was concluded that Chrysophyllum albidum extract showed antihyperlipidemic effect in rats fed with beef tallow supplemented diet.

Aim. To assess the efficacy and safety of plant stanols in patients with arterial hypertension (AH) and disorders of lipid metabolism, without clinical manifestations of atherosclerosis.Material and methods. The study included 40 patients — men at the age of 50-55 years, with AH (stage 1) and cholesterol above 5,0 mmol/l and LDL cholesterol above 3,0 mmol/l with low and medium risk (SCORE — 1-4%). Patients with coronary artery disease and other clinical manifestations of atherosclerosis, secondary hypertension, liver diseases, diabetes mellitus, secondary dyslipoproteinemia, cardiovascular diseases requiring constant therapy, bronchial asthma were excluded from the study. Patients were randomized into 2 groups of 20 people. In the study group of patients within 3 months received plant stanols (2 tab./day), in the control group — only healthy diet. In addition, patients with high blood pressure received antihypertensive therapy. Assessment of lipid parameters (total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides) was performed at baseline and after 3 months. At the beginning of the study, after 3 months of the study patients underwent a full medical examination. Safety control of plant stanols was carried out by determination of liver enzymes (aspartic transaminase (AST), alanine transaminase (ALT)), before and after the completion of the study.Results. Patients of two groups were comparable in baseline characteristics (lipid parameters, blood pressure level). After 3 months of research beginning patients from study group have statistically significant decrease of total cholesterol and LDL cholesterol. The average level of total cholesterol before treatment was 5,8±0,32 mmol/l, and after treatment — 5,3±0,32 mmol/l, p<0,001. The average level of LDL cholesterol before treatment was 3,6±0,26 mmol/l, and after treatment — 3,3±0,25 mmol/l, p<0,001. According to other lipid parameters (HDL cholesterol, triglycerides) significant differences are not obtained. As a result, there was a significant reduction in the total risk from 4% to 3,1%. As for the control group, the dynamics of lipid parameters were practically not observed. For example, the average level of total cholesterol before treatment was 5,7±0,39 mmol/l, and after treatment — 5,6±0,42 mmol/l. The average level of LDL cholesterol before treatment was 3,6±0,21 mmol/l, and after treatment — 3,6±0,21 mmol/l. The differences between the study and control groups in the reduction of total and LDL cholesterol were highly significant (p<0,001). The study did not reveal the dynamics of liver enzymes. The level of AST before treatment in the study group was 28,4±6,54, and after treatment — 29,5±5,56. ALT levels were 32,3±7,38 and 33,9±5,65, before and after the study, respectively.Conclusion. The study shows the high efficacy and safety of plant stanols. We found a significant decrease of the two most important parameters of lipid metabolism — total cholesterol and LDL cholesterol.
