Fatty fish are the richest natural sources of omega-3s, while lean fish generally contain lower amounts. This fish omega-3 chart compares common seafood based on the approximate amount of omega-3 per 3-ounce (85g) cooked serving.

Eating omega-3-rich fish may help:
- Support heart health
- Promote brain function
