To be checked at the randomization visit (V2):

- RI 01: Subject having followed the dietary recommendations over the wash-out period.

Exclusion Criteria:

• To be checked at the inclusion visit (V1):
• IE 01: Subject having experienced any cardiovascular event (cardiac infarction, angina attack, surgical or endoscopic coronary angioplasty, stroke, arterial disease, etc.).

• IE 22: Subject who is susceptible to not comply with dietary qualitative restriction during the study period.
• IE 23 Vulnerable subjects defined as individuals whose willingness to volunteer in the clinical trial may be unduly influenced by the expectation, whether justified or not, of benefits associated with participation, or of a retaliatory response from senior members of a hierarchy in case of refusal to participate. Examples are members of a group with a hierarchical structure, such as medical, pharmacy, dental and nursing students, subordinate hospital and laboratory personnel, employees of the pharmaceutical industry, members of the armed forces, and persons kept in detention.
• IE 24: Subject expected to be living in the same home as a current participating subject and to concomitantly receive some study products.
