Cod (Gadus morhua) is a demersal fish found in the North Atlantic and other cold waters. It has been a dietary staple for centuries, particularly in Northern European and Scandinavian cuisines. Cod is consumed fresh, frozen, dried (salt cod), and smoked. The fish is prized for its mild flavor, flaky white flesh, and versatility in cooking methods including baking, poaching, and frying.
A 100g serving of cooked cod contains approximately 20g protein, 1g fat, and negligible carbohydrate. Cod provides bioavailable selenium, phosphorus, vitamin B12, niacin, and iodine. The omega-3 content is modest compared to fatty fish like salmon, but still contributes to polyunsaturated fat intake. Cod is easily digestible and does not produce significant gas or bloating in most individuals.
Cardiovascular and Metabolic Effects
The omega-3 fatty acids in cod, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), may contribute to normal blood lipid profiles when included as part of a balanced diet. The high protein density (19–22g per 100g cooked) supports satiety and muscle protein synthesis. Cod contains no added sodium unless processed or salted; fresh or frozen unsalted cod is appropriate for sodium-restricted diets.
Tolerance and Intake Guidance
Fish, including cod, is one of the nine major food allergens recognised by the FDA. Individuals with a diagnosed fish allergy should avoid all cod products. Fish allergy is distinct from shellfish allergy; cross-reactivity can occur, and medical guidance should be sought. Mercury content in cod is low; the FDA classifies cod as a 'Best Choices' fish, meaning adults and pregnant women can consume up to 2–3 servings per week. Standard portion guidance is 100–150g per serving. Individuals taking anticoagulants should maintain consistent omega-3 intake but need not avoid cod.

Is cod high in mercury?
Cod has low mercury content and is classified as a 'Best Choices' fish by the FDA. Adults and pregnant women can safely consume up to 2–3 servings per week. It is considered one of the safer fish options for regular consumption.
How much omega-3 does cod contain?
Cod contains a modest amount of omega-3 fatty acids (EPA and DHA) per 100g of cooked fish. This is considerably less than fatty fish like salmon or mackerel, but can contribute to daily omega-3 intake when consumed as part of a varied diet.
Is cod suitable for people with fish allergies?
No. Cod is a fish and is one of the nine major FDA-recognised food allergens. Anyone with a diagnosed fish allergy should avoid all cod products.
