The protein content of cooked cod
Cod is widely recognized as a lean, high-protein fish. The protein it provides is considered a 'complete' protein, meaning it contains all nine essential amino acids that the body cannot produce on its own. For those tracking their macronutrient intake, understanding the specific amount of protein is key. While the raw fish contains a significant amount of protein, the cooking process removes water, which concentrates the protein per gram of weight. Most nutritional data references cooked portions to provide a realistic assessment.
For a standard 3-ounce (85-gram) serving of cooked Atlantic cod, you can expect to get around 19 grams of protein. A slightly larger 4-ounce portion (about 113 grams), often cited by sources like WebMD, will provide approximately 20 grams of protein. This confirms cod's status as an efficient source of lean protein for a variety of diets.
Factors influencing protein content
While the figures for protein in cod are fairly consistent, a few factors can cause slight variations:
- Species: There are different species of cod, with Atlantic and Pacific cod being the most common. A 3-ounce serving of cooked Pacific cod might have a slightly higher protein count, closer to 20 grams, compared to Atlantic cod.
- Cooking Method: The method used to cook the fish can affect its final nutritional composition. For instance, dry-heat cooking methods like baking or broiling will differ from poaching, which adds moisture. The addition of fats and oils during cooking, such as when frying, will increase the fat and calorie content but generally won't impact the core protein amount significantly.
- Cut of Fish: The nutritional value can vary slightly depending on the cut of the fish, such as a loin versus a tail portion.
Comparison of cod protein to other popular seafood
To put cod's protein content into perspective, here is a comparison with other commonly consumed seafood, based on a 3-ounce serving size, using values cited in search results and USDA data.
| Seafood Type | Protein (per 3 oz. serving) | Fat (per 3 oz. serving) | Calories (per 3 oz. serving) |
|---|---|---|---|
| Cod (cooked) | ~19-20 g | ~1 g | ~90 |
| Salmon (cooked) | ~22 g | ~11-12 g | ~150-170 |
| Shrimp (cooked) | ~21 g | ~0.5 g | ~85 |
| Tuna (Yellowfin, cooked) | ~30 g | ~1 g | ~139 |
This comparison highlights that while cod is a powerhouse of lean protein, other fish like salmon or tuna offer different macronutrient balances. Salmon, for example, is fattier but also contains more protein and higher levels of Omega-3s. For those seeking maximum lean protein with minimal fat, cod is an excellent choice.
Nutritional benefits beyond protein
In addition to its impressive protein profile, cooked cod provides a wealth of other important nutrients that contribute to overall health. Incorporating cod into your diet offers a range of vitamins and minerals, including:
- B Vitamins: Cod is a good source of B vitamins, particularly B12 and B6. Vitamin B12 is crucial for nerve function and red blood cell formation, while B6 is essential for hundreds of chemical reactions in the body.
- Selenium: This mineral acts as a powerful antioxidant, protecting your cells from damage. A single serving of cod often provides a significant portion of the recommended daily intake for selenium.
- Phosphorus: An essential mineral, phosphorus plays a critical role in strengthening bones and teeth, as well as helping the body release energy from food.
- Omega-3 Fatty Acids: Though not as rich in omega-3s as fattier fish like salmon, cod still contributes to your intake of these important fatty acids, which are beneficial for heart and brain health.
How cooked cod supports a healthy diet
Because of its low-fat content and rich protein profile, cod is an ideal food for various dietary goals. For those focused on weight management, it provides satiating protein without excessive calories. For athletes and fitness enthusiasts, the high-quality, complete protein supports muscle repair and growth. Its mild flavor and flaky texture also make it a versatile ingredient, suitable for many healthy cooking methods like baking, broiling, and poaching. For a recipe idea that utilizes cod in a healthy way, consider trying a simple poached cod dish or adding it to fish tacos. The mild flavor makes it easy to integrate into many cuisines.

Conclusion
In summary, cooked cod is an exceptional source of lean, high-quality protein, providing roughly 19-20 grams in a typical 3 to 4-ounce serving. As a complete protein, it delivers all the essential amino acids needed for bodily function. Furthermore, it contributes important vitamins like B12 and minerals such as selenium and phosphorus. Its low-fat nature makes it a valuable addition to many healthy diets, supporting everything from muscle maintenance to overall nutritional intake.
