Omega-3s possess antioxidant potential, says gene expression study
Omega-3 fatty acids may offer antioxidant potential by modifying gene expression linked to antioxidant enzymes, says a new study from Germany.
Fish oil supplements were associated with up-regulation of expression of antioxidative enzymes, and the down-regulation of pro-oxidative enzymes, with effects particularly notable in people with abnormal blood lipid profiles.
“To the best of our knowledge, this is the first intervention study disclosing gene expression changes in normo- and dyslipidemic subjects after fish oil supplementation,” wrote researchers from Leibniz University of Hannover in Nutrition & Metabolism .
“We suggest that n-3 PUFAs [polyunsaturated fatty acids] may have an antioxidative potential.”
