  Purpose
The investigators' project has for principal objective to evaluate the impact of three specific ruminant milk fats with a Trans Fatty Acid content ranging from 2.9% to 12.2% obtained by modification of the cow's diet on cardiovascular risk factors in healthy subjects.

Condition Intervention
Cardiovascular Disease Dietary Supplement: Ruminant trans fatty acid enriched diet - lowest ratio Dietary Supplement: Ruminant trans fatty acid enriched diet - medium ratio Dietary Supplement: Ruminant trans fatty acid enriched diet - highest ratio

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Prevention
Official Title: Rationale, Study Design and Baseline Data of the TRANSQUAL Clinical Trial: A Study to Evaluate the Impact of Different Milk Fatty Acid Profiles on Cardiovascular Risk Factors in Healthy Volunteers; Focus on Trans Fatty Acids

Detailed Description:
111 healthy, normolipemic men and women (18y to 50y) have been recruited for a monocentric, randomised, double-blind, controlled 4-week study. All the volunteers consumed 3 experimental products (butter, dessert cream and cakes) made with one of the 3 specific milk fats up to 55 g fat/day.
