The Protein Breakdown: How Much Is In 100 g of Salmon?
For a 100-gram (or 3.5-ounce) portion, the amount of protein you receive can range from approximately 18 to 30 grams, depending on several key variables. As a rich source of complete protein, salmon provides all the essential amino acids your body needs to function optimally. For context, experts suggest aiming for 20–30 grams of high-quality protein per meal to support optimal health. A typical 100-gram portion of salmon easily meets this recommendation.
Factors That Influence Salmon Protein Content
The protein content in salmon is not a static number and can be influenced by the following factors:
Wild vs. Farmed Salmon
There is a notable nutritional difference between wild-caught and farmed salmon. Wild salmon are generally leaner and have a higher protein-to-fat ratio due to their active lifestyle and natural diet of small fish and crustaceans. Conversely, farmed salmon has a higher overall fat content because of its more controlled and less active environment. While farmed salmon often contains a lower percentage of protein by weight compared to wild varieties, the difference is not drastic.
Species of Salmon
Not all salmon species are created equal in their nutritional profile. Popular varieties show slight variations in their protein and fat content:
- Sockeye Salmon: Per 100g, cooked wild sockeye typically contains around 21.9 grams of protein.
- Chinook (King) Salmon: A 100g portion of wild Chinook may offer approximately 19.9 grams of protein.
- Atlantic Salmon (Farmed): Due to higher fat, 100g of farmed Atlantic salmon typically provides about 20–22 grams of protein in its raw form.
- Cooked Wild Atlantic: When cooked, wild Atlantic salmon can deliver up to 25 grams of protein per 100g as moisture is lost.
Preparation and Cooking Methods
Cooking significantly impacts the final protein count per 100g. When salmon is cooked, it loses a portion of its water content, which concentrates the protein and other nutrients. For example, 100g of cooked salmon will have more grams of protein than 100g of raw salmon. Methods like smoking can also change the protein profile. Smoked salmon typically contains 18–25 grams of protein per 100g, but serving sizes are often smaller.
Beyond Protein: Salmon's Complete Nutritional Profile
While protein is a major benefit, salmon is also rich in a variety of other essential nutrients. Here is a comparison of the key nutritional values in a 100-gram serving of wild-caught versus farmed Atlantic salmon, based on cooked weight:
| Nutrient (per 100g cooked) | Wild Atlantic Salmon | Farmed Atlantic Salmon |
|---|---|---|
| Protein | ~25 g | ~22 g |
| Calories | ~182 kcal | ~206 kcal |
| Total Fat | ~8 g | ~12 g |
| Omega-3s (EPA & DHA) | Excellent Source (~2.2g) | Excellent Source (~2.3g) |
| Vitamin B12 | 127% DV | 117% DV |
| Selenium | 85% DV | 75% DV |
| Potassium | 13% DV | 8% DV |
The Health Benefits of a Protein-Rich Fish
Regularly including salmon in your diet offers numerous health advantages beyond just muscle building:
- Muscle Repair and Growth: The complete protein profile provides the amino acids necessary for repairing and building muscle tissue, especially crucial after exercise.
- Bone Health: Salmon's protein and omega-3s work together to support bone density and prevent age-related muscle and bone loss.
- Anti-Inflammatory Properties: In addition to protein, the omega-3s in salmon have powerful anti-inflammatory effects that can benefit a range of chronic conditions.
- Cognitive Support: Omega-3 fatty acids, particularly DHA, are vital for brain function, memory, and may help reduce the risk of cognitive decline.
- Heart Health: Omega-3s also help lower blood pressure, reduce triglycerides, and decrease the risk of heart disease.
Incorporating Salmon Into Your Diet
Making salmon a regular part of your meals is both delicious and beneficial. A 100-gram serving can be grilled, baked, or pan-seared and paired with vegetables and whole grains for a balanced meal. Canned and smoked varieties also offer convenient, high-protein options, though canned salmon often contains bones and skin, which are rich in calcium. For recipe ideas, consider a simple baked salmon with herbs, a salmon salad, or a protein-packed poke bowl with raw salmon. The versatility and flavor of salmon make it easy to enjoy multiple times a week as recommended by many health organizations.
Choosing the Right Salmon
When purchasing salmon, consider your preferences and priorities. Wild salmon, with its leaner profile and more robust flavor, is an excellent choice. Farmed salmon is typically more widely available and has a milder flavor and higher fat content. Both are nutritious choices, providing a healthy dose of protein and omega-3s. Ultimately, adding either variety to your diet is a smart move for your health.

Conclusion: A High-Protein Choice for Your Diet
In summary, 100 grams of salmon is an exceptional source of protein, delivering between 18 and 30 grams depending on the type and preparation. This makes it an effective way to meet daily protein goals while also providing a wealth of other important nutrients like omega-3 fatty acids, B vitamins, and minerals. Whether you opt for wild or farmed, cooked or raw, salmon remains a top-tier choice for supporting muscle, bone, and heart health.
