Stearidonic acid as a ‘pro-eicosapentaenoic acid’Harris, William S.Current Opinion in Lipidology: February 2012 - Volume 23 - Issue 1 - p 30–34 doi: 10.1097/MOL.0b013e32834f0f0c NUTRITION AND METABOLISM: Edited by Paul Nestel and Ronald P. Mensink Abstract Author Information Purpose of review ω-3 Fatty acids continue to be promoted as cardioprotective, generating an increased demand for these nutrients. Ocean-based supplies are limited, and so land-based sources are being sought. Stearidonic acid-fortified soybean oil may help to meet this demand. Recent findings Stearidonic acid has been shown in animal and human studies to be more effective than its precursor, α-linolenic acid, in enriching membranes with eicosapentaenoic acid. Hence, stearidonic acid can serve as a ‘pro-eicosapentaenoic acid’. Summary Stearidonic acid-fortified soybean oil may be able to help close the gap between actual and recommended intakes of ω-3 fatty acids in an environmentally friendly manner. aSanford School of Medicine, University of South Dakota, Sioux Falls, South Dakota bHealth Diagnostic Laboratory Inc., Richmond, Virginia, USA Correspondence to William S.
