Purpose

The main purpose of this study is to examine whether n-3 PUFA-induced changes in metabolic risk factors are influenced by genetic variations within genes acting as fatty acids sensors.

Estimated Enrollment:	200
Study Start Date:	October 2009
Estimated Study Completion Date:	March 2019
Primary Completion Date:	December 2011 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Experimental: capsules omega-3 Omega-3 supplementation (3g EPA+DHA/d)	Dietary Supplement: n-3 PUFA supplementation 3g per day of n-3 PUFA supplementation (1.9g EPA, 1.1g DHA). 5 capsules per day (1g fish oil each, 5g of fish oil/day) Other Name: MEG-3 from Ocean Nutrition Canada,Nova Scotia,Canada.

Detailed Description:

The main purpose of this study is to examine whether n-3 PUFA-induced changes in metabolic risk factors are influenced by genetic variations within genes acting as fatty acids sensors. To do so, the metabolic risk factor response to an n-e PUFA supplementation will be compared in carriers and non-carriers of polymorphism within genes acting as fatty acids sensors.
