Outcomes

Primary Outcome Measures

Postprandial metabolic, inflammatory and endothelial response
Metabolic: Plasma glucose, insulin and triglyceride levels (T= 0,1,2,3,4,5 and 6 hrs) Inflammatory: C-reactive protein (CRP), Plasminogen activator inhibitor-1 (PAI-1), Tumor necrosis factor-alpha (TNF-a), Interleukin-6 (IL-6), Inter-Cellular Adhesion Molecule-1 (ICAM-1) and Monocyte chemotactic protein-1 (MCP-1) (T=0, 2, 4 and 6 hrs). Endothelial function: Macro vascular regional arterial stiffness by Pulse Wave Analysis (PWA) (T=0, 3 and 6 hrs).

Secondary Outcome Measures

Satiety markers and Oxidative stress
Satiety: Glucagon-like peptide-1 (GLP-1) (T=0,2,4 and 6 hrs). Oxidative stress: Peripheral blood mononuclear cells (PBMC) (T=0,3 and 6 hrs).

5. Study Description

Brief Summary
The main objective is to investigate the postprandial effect of arginine-rich protein (i.e. pea-protein) on metabolic control, inflammation and endothelial function after a high-fat meal in subjects with characteristics of the metabolic syndrome.
Detailed Description
Arginine is potential interesting considering the metabolic syndrome. Studies so far indicated both long-term effects, as well as acute - postprandial - actions; especially when metabolism is already challenged, e.g. in diabetic patients or after a high-fat meal. If arginine-rich proteins are equally effective is not known. Therefore we are interested in the effect of (arginine rich) protein on postprandial (dys)metabolism, inflammation and endothelial function, within 6 hours after a meal.
