A substantial amount of evidence exists supporting the heart-health benefits of eicosapentaenoic acid and docosahexaenoic acid (EPA and DHA), marine-derived omega-3 fatty acids. However, much less evidence exists to demonstrate the positive effects of alpha-linolenic acid (ALA), a plant-based omega-3 fatty acid.
“The benefits reported for EPA and DHA are stronger because supplements of EPA and DHA were tested, and EPA and DHA was the only difference between the treatment and control groups,” said Jennifer Fleming, instructor and clinical research coordinator in nutritional sciences. “In contrast, in the ALA studies, there were diet differences beyond ALA between the treatment and control groups.”
