Endothelium biomarkers, Atherosclerotic disease, Endothelial function, Nutritional stimuli
Brief summary
The main objective is to develop and validate new endothelial function markers discriminating and reproducible by assessing the ability to reveal changes in endothelial function in response to positive and negative nutritional stimuli.
Detailed description
The study will be randomized (on the order of taking the products: a single dose of lipids or a single dose of flavonoids), single-blinded, cross-over for each population (healthy and metabolic syndrome).
