Study: GM Soybean Oil Raises EPA, DHA Levels

Researchers at the University of South Dakota explored the potential of genetically modified (GM) soybean oil as a plant source of omega-3 that boosts eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) levels.

The GM soybean oil contains approximately 20% stearidonic acid (SDA), the delta-6 desaturase product of alpha-linolenic acid (ALA).

The 16-week study, published in Lipids, sought to determine whether an increase in SDA the diet would affect the omega-3 index. Thirty three participants ages 21-70 were randomized into three groups and given either soybean oil (SOB), SBO with EPA capsules, or the genetically modified SDA-SBO. After 16 weeks, the participants’ EPA and DHA levels were measured. Results showed the omega-3 index increased in the EPA and SDA-SBO groups, and there was no significant difference between the results. The control group taking the SOB did not show increases in EPA or DHA levels.
