Detaillierte Beschreibung
This human dietary intervention study is a double blind, randomized, placebo controlled, cross over trial with 3 arms, carried out on subjects with predisposition to cardiometabolic syndrome (based on weight circumference, blood triglyceride or blood cholesterol, glycemia and hypertension). This study aims to demonstrate transient improvement in vascular endothelial function (with Flow Mediated Dilatation (FMD) as main criteria) with consumption of vegetable proteins (rich in leucine, cysteine and arginine) by comparison with animal proteins and with a control without proteins.
The 33 recruited participants will receive the 3 yogurts in a random order. For each subject, the study is divided into 4 visits.
To summarize: Visit 1 (D-7) = inclusion, Visit 2 (D0: treatment period N°1), Visit 3 (D28 : treatment period N°2), Visit 4 (D56 : treatment period N°3). The wash-out periods between treatment period (duration: 4 weeks) may be extended until 5 weeks for the convenience of participants.
The protocol includes a total of 4 visits to PIC/CIC Inserm 1405 of the Clermont-Fd University Hospital.
