Higher DHA Levels Tied to Less Depression in People With Belly Fat

Key Insight

This study suggests DHA levels specifically, more than EPA, may relate to mood in people with obesity.


Obesity and depression often travel together, and omega-3 fats may be part of that link. In over 4,400 US adults, those with more DHA in their blood were less likely to have belly fat and depression together. EPA, the other main fish oil fat, showed no clear connection. This is a snapshot in time, so it can't prove DHA caused the difference.
