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 cardiovascular diseases (CVD) based on age and overweight. This study aims to demonstrate the vascular protective effects (with Flow Mediated Dilatation (FMD) as main criteria) of the consumption of a flavanone rich orange juice or of orange flavanones by comparison with a control sugary drink alone. The 42 recruited participants will receive the 3 drinks in a random order. For each subject, the study is divided into 3 identical experimental periods of 45 days (period 1,2,3): including 3 days prior to the beginning of the product intake, during which specific dietary guidelines, samplings and measures will be asked to be performed at home followed by a 6 weeks period of consumption of each of the 3 beverages). A period of 4 to 6 weeks of wash-out is planned between each experimental period. To summarize: Visit 1 (D-14) = inclusion, Visit 2 (D1: baseline) to 3 (D42) = period 1, Visit 3 (D42) to 4 (D70) = wash out 1, Visit 4 (D70) to 5 (D111) = period 2, Visit 5 (D111) to 6 (D139) = wash out 2, Visit 6 (D139) to 7 (D180) = period 3. The wash-out periods (minimum duration: 4 weeks) may be extended until 6 weeks for the convenience of participants. The protocol includes a total of 7 visits to PIC/CIC Inserm 1405 of the Clermont-Fd University Hospital. The total duration of the study will be between 28 and 34 weeks
