Cod

Overview

Cod is a lean white fish providing modest amounts of omega-3 fatty acids, vitamin B12, selenium, and other trace minerals, together with highly digestible protein. Compared with oily fish such as salmon or mackerel, cod contributes smaller absolute amounts of EPA and DHA but still adds marine omega-3s, micronutrients, and protein at a relatively low energy cost [1]. This makes cod useful in meals where the focus is on vegetables and whole grains, with fish acting as a lighter protein component.

Within the BRAIN Diet framework, cod functions as a lean marine protein that can be rotated with higher-fat oily fish rather than replacing them. Its protein has a high digestible indispensable amino acid score (DIAAS), indicating excellent indispensable amino acid coverage [2]. This makes cod a flexible option when meals already provide substantial fats from other ingredients, allowing marine protein and modest omega-3 intake without substantially increasing total dietary fat.

Key Nutritional Highlights

• Provides complete, highly digestible protein with excellent DIAAS coverage [2].
• Modest EPA/DHA relative to oily fish; still contributes marine omega-3s at low energy cost [1].
• Selenium and vitamin B12 vary by species; see nutrition table for this FDC entry.
• Lean marine protein (~61 kcal per 100 g) for meals already containing other fat sources [1].

Food Context

Sourcing

• Choose cod from fisheries with transparent stock assessments and sustainability practices; colder-water wild-caught cod from well-managed stocks can be a relatively low-impact choice [1,2].
• As a lower-trophic species relative to large predatory fish, cod generally accumulates less mercury, but it should still be consumed as part of a varied fish intake pattern for both sustainability and risk management [1,2].
