Animal and human studies suggest that a malleable protein matrix (MPM) from whey decreases plasma lipid concentrations and may positively influence other components of the metabolic syndrome such as glucose metabolism and blood pressure (BP). The primary objective of this double-blind, multi-centre trial was to investigate the effects of a low-fat yoghurt supplemented with whey MPM on fasting TAG concentrations in patients with the metabolic syndrome. A total of 197 patients were randomised to receive MPM or a matching placebo yoghurt identical in protein content (15g/d). Patients were treated during 3 months with two daily servings of 150g yoghurt each to compare changes from baseline in efficacy variables. MPM treatment resulted in a significantly larger reduction of TAG concentrations in comparison to placebo (relative change-16%, P=0•004). The difference was even more pronounced in subjects with elevated fasting TAG (200mg/dl) at baseline (-18%, P=0•005). The relative treatment difference in fasting plasma glucose was-7•1mg/dl (P=0•089). This effect was also more pronounced in subjects with impaired fasting glucose at baseline (-11mg/dl, P=0•03). In patients with hypertension, the relative treatment difference in systolic BP reached-5•9mmHg (P=0•054). The relative treatment difference in body weight was-1•7kg (P=0•015). The most common adverse events were gastrointestinal in nature. Conclusions from the present study are that consumption of a low-fat yoghurt supplemented with whey MPM twice a day over 3 months significantly reduces fasting TAG concentrations in patients with the metabolic syndrome and improves multiple other cardiovascular risk factors. © 2011 The Author.

Malleable protein matrix (MPM) is a unique whey-derived ingredient obtained through a fermentation process using proprietary lactic acid bacteria strains from the Lactobacillus kefiranofaciens species. Because evidence from animal models suggests that MPM decreases serum lipid concentrations, the purpose of the present trial was to assess the hypothesis that MPM exerts lipid-lowering effects in humans. A total of 161 subjects (50% male; age 54.5±9.8 yr, body mass index 26.3±3.6 kg/m2) with hypercholesterolemia with baseline low-density lipoprotein cholesterol (LDL-C) levels of 181±30 mg/dL and normal triglyceride (TG) levels (131±55 mg/dL) were randomized to receive MPM (2 × 15 g/d) or matching placebo. A 6-wk run-in phase was followed by a double-blind 12-wk treatment phase after randomization. The data were analyzed on an intention-to-treat basis. The primary outcome measure was the percentage change of LDL-C. The secondary outcome measures were changes in TG and high-density lipoprotein cholesterol concentrations as well as changes in other cardiovascular risk factors. After 12 wk of treatment, the relative TG decrease from baseline reached 9.8%, whereas LDL-C was slightly decreased (by 1.5%) following MPM treatment compared with placebo in the intention-to-treat cohort. The treatment effect on TG reduction was much higher in the subset of subjects having TG levels at baseline of 150 mg/dL or above (n=42), reaching 20.0% compared with placebo. High-density lipoprotein cholesterol concentrations, blood pressure, and fasting blood glucose remained unchanged, whereas a positive treatment effect was seen on hemoglobin A1c. The MPM product was tolerated well without severe adverse events. In conclusion, MPM has significant TG-lowering properties in subjects with combined hypercholesterolemia and higher TG levels. Its effects on LDL-C concentrations and glucose metabolism deserve further investigation. © 2011 American Dairy Science Association.

Previously, we reported that a malleable protein matrix (MPM), composed of whey fermented by a proprietary Lactobacillus kefiranofaciens strain, has immunomodulatory and anti-inflammatory properties. MPM consumption leads to a considerable reduction in the cytokine and chemokine production (tumor necrosis factor-α, interleukin-1β, and interleukin-6), thus lowering chronic inflammation or metaflammation. Inhibition of metaflammation should provide positive impact, particularly in the context of dyslipidemia, insulin resistance, and hypertension. In this study, we investigated whether short-term MPM supplementation ameliorates those features of metabolic syndrome (MetS). The ability of MPM to potentially regulate triglyceride level, cholesterol level, blood glucose level, and hypertension was evaluated in different animal models. MPM lowers triglyceride level by 37% (P < .05) in a poloxamer 407 dyslipidemia-induced rat model. It also reduces total cholesterol by 18% (P < .05) and low-density lipoprotein-cholesterol level by 32% (P < .05) and raises high-density lipoprotein-cholesterol level by 17% (P < .01) in Syrian Golden hamsters fed a high fat/high cholesterol diet for 2 weeks. MPM reestablishes the fasting glucose insulin ratio index to normal levels (P = .07) in this latter model and lowers the plasma glucose level area under the curve (-10%, P = .09) in fructose-fed rats after 2 weeks of treatment. In spontaneously hypertensive rats, MPM-treated animals showed a reduction of SBP by at least 13% (P < .05) for 4 weeks. Results from this study suggest that MPM is a functional ingredient with beneficial effects on lipid metabolism, blood glucose control, and hypertension that might contribute to the management of MetS and thus reducing the risk of cardiovascular diseases. © 2010, Mary Ann Liebert, Inc. and Korean Society of Food Science and Nutrition.
