Misleading headlines about a recent study implied that fish oil provides "no benefit" for the cognitive health of older people-contradicting at least 11 other studies. More specifically, the nutrient discussed was DHA, one of two key omega-3 fats (EPA is the other) found in fish oil and certain algae.
DHA is a vital part of the structure of the brain and nervous system, and because our bodies can't make it, we must get DHA from food or supplements. So why would it seemingly fail to improve cognitive health? People in the study took only 350 mg daily-and that's just not enough.
Adam Ismail, executive director of GOED (short for Global Organization for EPA and DHA Omega-3s), a nonprofit global organization that studies omega-3s, points out that multiple other studies found that, "Greater than 1g of DHA per day was required to improve some aspects of cognitive function in older adults."
