Cod and mahi mahi are two of the most famous and widespread fishes. In this article, we will compare these species, focusing on their nutritional profile and health impact, and discussing their actual differences.
Actual differences
Cod (1) is a common name for a demersal fish from the genus Gadus. It is usually consumed in grilled, baked, deep-fried, or broiled form. Cod has a non-fishy, mild, and a bit sweet taste. It is widespread in the Atlantic and Pacific areas. You can easily find cod in markets, frozen or fresh.
Mahi mahi (2) is a yellow or bright-green predatory fish mostly consumed in Hawaii. However, it can be found and used worldwide. In another way, this fish is called a dolphinfish or dorado. Mahi mahi has a mild, sweeter, and non-fishy flavor. It is usually fried with herbs, lemon, and spices. The fish lives in the Gulf of Mexico and the Caribbean sea.

Vitamin Comparison
Health impact
Cardiovascular health
Cod and mahi mahi consumption is linked to a lower heart disease risk (3). This is due to omega-3 fatty acid composition. These are long-chain essential fatty acids that are not produced in the human organism. Hence we should get them with the food we consume.
Health risks
Mahi mahi is classified as food with moderate amounts of mercury. Although this mineral is not toxic for healthy middle-aged people, it can harm young people, children, and pregnant women (4). Avoiding excessive fish consumption to prevent mercury poisoning would be best. Cod is lower in mercury than mahi mahi, making itself a better choice to avoid mercury poisoning (5).
Cod can be a source of parasites if consumed raw without cooking or freezing (6).
