9. Canned Light Tuna and Pacific Pollock (250 to 500 mg per 3-Ounce Serving)

Canned light tuna (primarily skipjack) and wild Pacific pollock offer accessible entry points into routine seafood consumption. While their omega-3 yields fall into a lower tier compared to wild salmon or sardines, a single serving still provides between 250 and 500 milligrams of essential fatty acids. This meets the minimum baseline daily intake advised by international nutrition boards. Their mild flavor, low cost, and widespread availability make them reliable options for constructing healthy, everyday meals.
