Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this study the investigators aimed at verifying whether consumption of a sheep cheese, naturally enriched in ALA, CLA and VA, would modify the plasma lipid and endocannabinoid profiles in mild hypercholesterolemic subjects. This study was a 3-week, randomized, double blind, controlled, cross over clinical trial, conducted at the State Hospital Brotzu in Cagliari, Italy. The subjects were randomly assigned to eat 90g/d of the control or enriched cheese for 3 weeks, with a cross over after 3 weeks of washout.

regular cheese

This study was a 3-week, randomized, double blind, controlled, cross over clinical trialy. The subjects were randomly assigned to eat 90g/d of the control or enriched cheese for 3 weeks, with a cross over after 3 weeks of washout. The study included 5 visits: 2 screening/baseline visits at weeks -1 and 0, 1 end of intake of 90 g/d of cheese visit at week 3, 1 end of the first wash out visit at week 6, and 1 end of treatment after crossing over visit at week 9. This procedure was subsequently repeated with a cheese intake of 45 g/d

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Adult volunteers with diagnosed mild hypercholesterolemia (total cholesterol 220-290 mg/dL)

Exclusion Criteria

* Pregnant (or those planning to become pregnant during the study period) and lactating women
* Also individuals with a self-reported history of diabetes, inflammatory bowel disease, pancreatitis, gallbladder or biliary disease in the past 12 months, and lactose intolerance before the screening visit.
* Those with a history of cancer (except non-melanoma skin cancer) in the 2 years before screening, or of any major trauma or surgical event within 3 months before screening.
* Volunteers with the following characteristics were also excluded:

* total cholesterol ≥300 mg/dL, serum triglycerides ≥250 mg/dL or ≤ 200 mg/dL, \*HDL ≥70mg/dL, BMI ≥ 30
* uncontrolled hypertension (systolic blood pressure ≥160 mm Hg or diastolic blood pressure ≥100 mm Hg) at screening.
* Use of lipid-altering medications or supplements, and of anticoagulants, during the 2 weeks before screening and throughout the study was prohibited.
* Furthermore, we selected subjects with an Apo E aplotype 3/3, the most common in Sardinia, in order to avoid any variability in cholesterolemia due to a different dietary response.
