                                According to the USDA, a 3-ounce serving of cooked Atlantic cod contains approximately 90 calories, 19 grams of protein, and only 1 gram of fat. However, when asking, "What is the healthiest cod?", the answer depends on your specific nutritional goals, as factors like omega-3 content and mercury levels vary significantly among species.
