In the investigation of "Stearidonic Acid-Enhanced Soybean Oil: A Plant-Based Source of (n-3) Fatty Acids for Foods" by Harris WS., posted in US National Library of Medicine National Institutes of Health, researchers found that Stearidonic acid (SDA) is a metabolic precursor of EPA that can be provided by SDA-enhanced soybean oil. Such a product can provide a sustainable source of (n-3) fatty acids that does not endanger fish stocks. Two clinical trials have demonstrated that SDA-enhanced soybean oil can significantly improve an emerging marker of cardiovascular health, the omega-3 index (RBC EPA+DHA) and suggests that raising EPA tissue levels, independent of changes in DHA, can have clinical benefit. Thus, the consumption of foods containing SDA-enhanced soybean oil may be both a practical and sustainable approach to enriching tissues with beneficial (n-3) fatty acids.
