Cheese Intake,CLA and Hypercholesterolemia - Full Text View

Purpose

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.

Primary Outcome Measures:

decrease of LDL-cholesterol levels [ Time Frame: 3 weeks ] [ Designated as safety issue: Yes ]
42 adult volunteers (19 male and 23 female) with diagnosed mild hypercholesterolemia (total cholesterol 220-290 mg/dL), 30-60 years of age, were recruited.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 were excluded. 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, or uncontrolled hypertension at screening.

Secondary Outcome Measures:

endocannabinoid levels [ Time Frame: 3 weeks ] [ Designated as safety issue: No ]
Modification of endocannabinoid levels during intake of CLA enriched cheese.

Eligibility

Ages Eligible for Study:	30 Years to 60 Years

Accepts Healthy Volunteers:	No

Criteria

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.
