Calculating the Protein in 120g of Cod
To determine exactly how much protein is in 120g of cod, it's best to start with a standard measurement and scale it up. Most nutritional data is provided per 100g, which makes the calculation straightforward. Raw Atlantic cod typically contains about 18 grams of protein per 100g. Cooked cod tends to have a slightly higher protein concentration due to water loss during the cooking process. For instance, some sources indicate that cooked cod can offer around 20 grams of protein per 100g.
Based on these figures, here's the calculation for a 120g portion:
- Raw Atlantic Cod: (18g protein / 100g) x 120g = 21.6g of protein
- Cooked Cod: (20g protein / 100g) x 120g = 24g of protein
It's important to note that these are general estimates, and the precise amount can vary. Different cod species also have slightly different nutritional profiles. For example, some data shows that a 120g fillet of cod could contain up to 21.4 grams of protein, while a similar serving of battered, processed cod may have a slightly lower protein content relative to its total weight.
Factors Affecting Cod's Nutritional Value
Several elements can influence the total protein and nutritional value of your cod fillet. Understanding these can help you maximize its health benefits.
- Cooking Method: Frying cod, especially in fatty oils, will increase its calorie and fat content, while cooking methods like baking, broiling, or steaming preserve its lean protein status. For example, a battered and fried cod portion will have significantly different macros than a plain baked fillet.
- Species of Cod: The two most common types are Atlantic and Pacific cod. While both are excellent protein sources, they have slightly different compositions. A cooked 85g (3oz) portion of Pacific cod has about 20g of protein, and the same size Atlantic cod has around 19g, though these numbers can vary by preparation.
- Processing: Pre-prepared or processed cod products, like battered fish, often contain added ingredients that change the nutritional breakdown. These products tend to have more carbohydrates and fat than a simple fillet.
How Cod's Protein Compares to Other Fish
Cod is known for being a very lean, low-fat source of high-quality protein. When put side-by-side with other popular seafood choices, its profile is distinct. The table below compares the protein content of a standard 3-ounce (85g) cooked serving of several fish varieties.
| Seafood Type | Serving Size (approx. 85g) | Protein (grams) | Notes |
|---|---|---|---|
| Cod (Atlantic) | 3 ounces | 19g | Very lean, high in protein |
| Salmon (Atlantic) | 3 ounces | 22g | Higher in fat and omega-3s |
| Tuna (Canned) | 3 ounces | 17g | Varies by packing medium |
| Halibut | 3 ounces | 22g | Richer texture, good protein |
| Shrimp | 3 ounces | 22g | Lean protein, low calories |
As the table shows, cod holds its own as a competitive protein source, especially for those seeking a low-fat option. While salmon offers more protein per ounce and significant omega-3 benefits, it also contains more fat. Cod provides a solid amount of protein for a lean, mild-flavored white fish.
Beyond Protein: Cod's Other Nutritional Perks
In addition to its protein, cod is rich in essential vitamins and minerals that contribute to overall health. It is particularly known for its high content of B vitamins, especially B12, which is vital for nerve function and DNA synthesis. It also provides significant amounts of selenium, a powerful antioxidant that helps protect cells from damage, and phosphorus, which is crucial for bone health. These nutrients, combined with its low-calorie, low-fat profile, make cod an excellent addition to a balanced diet.
Conclusion
In summary, a 120g portion of cod provides a substantial amount of lean, high-quality protein, typically ranging from 21 to 28 grams depending on preparation and species. Cod's nutritional benefits extend beyond its protein, offering a rich source of B vitamins, selenium, and phosphorus while remaining low in calories and fat. Whether baked, broiled, or steamed, incorporating cod into your meals is an effective way to boost your protein intake and support your overall health.
