Which of the following is considered a lean fish?

Cod is considered a lean fish because it has a low fat content compared to the other options provided. Lean fish typically contain less than 5 grams of fat per 100 grams, making cod a popular choice for healthier meal options. It boasts a mild flavor and flaky texture when cooked, which can make it versatile for various culinary applications.

Salmon and mackerel, on the other hand, are known for their higher fat content, particularly healthy omega-3 fatty acids, which contribute to their classification as fatty fish. Tuna can also contain more fat, especially when referring to certain types of tuna like bluefin. Thus, choosing cod highlights an emphasis on lower fat choices in culinary practice, aligning well with guidelines for healthy eating.
