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 02: Subject suffering from any serious or chronic liver, renal, cardiovascular, respiratory, endocrine or metabolic disorders.

* IE 09: Subjects having stopped their hypocholesterolemic drugs or products for less than 3 months
* IE 10: Subject with known lactose intolerance.
* IE 11: Subject with known allergy or hypersensitivity to plant sterols and to any component of the study product (milk protein for example).
* IE 12: Subjects having sitosterolemia.
* IE 13: Subject who had any surgery or intervention requiring a general anaesthesia in the preceding 4 weeks, or who plans to have one during the course of the study.
* IE 14: Subject receiving (currently or in the 4 last weeks) systemic treatment or topical treatment likely to interfere with evaluation of the study parameters.
* IE 15: Subject involved in any other clinical study within the preceding month or in the exclusion period after another clinical study.
* IE 16 Subject having blood sample of 200 mL or more taken (e.g., donated blood) within 1 month, or 400 mL or more within 3 months before the start of the present study.
* IE 17: Subject with heavy alcohol intake (\> 60 g/day).
* IE 18: Subject taking any treatment for anorexia, weight loss, or any form of treatment likely to interfere with metabolism or dietary habits (e.g. hypolipemic, hypoglycaemic treatments).

* IE 20: For female subject: subject likely to change her contraceptive method or hormone replacement therapy during the study.
* IE 21: Subject in a situation, which in the investigator's opinion could interfere with optimal participation in the present study (e.g. -products consumer) or could constitute a special risk for the subject.
* 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.
