How much protein is in Atlantic salmon? A complete guide

3 min read

According to the USDA, a 3.5-ounce (100g) serving of raw farmed Atlantic salmon contains about 20 grams of protein, making it an excellent source for a protein-rich diet. The exact amount of protein in Atlantic salmon can vary based on whether it is wild or farmed, and how it is prepared.

Quick Summary

This guide details the protein content in both farmed and wild Atlantic salmon, explores the nutritional differences between them, and compares salmon's protein richness to other popular protein sources.

Key Points

  • Protein Quantity: A 3.5-ounce (100g) serving of raw farmed Atlantic salmon contains about 20g of protein, while wild salmon can offer a higher protein-to-calorie ratio.

  • Farmed vs. Wild: Farmed salmon has higher total fat, whereas wild salmon is leaner and higher in protein per calorie, with a more balanced omega-3 fatty acid ratio.

  • Cooking Effect: Cooking concentrates protein by removing moisture, meaning a 100g portion of cooked salmon has more protein than an equal raw portion.

  • Complete Protein Source: Atlantic salmon is a complete protein, supplying all the essential amino acids necessary for muscle repair and general body function.

  • Beyond Protein: In addition to protein, salmon is rich in heart-healthy omega-3s, B vitamins, vitamin D, and minerals like selenium and potassium.

  • Health Benefits: The protein and other nutrients in salmon support muscle maintenance, bone health, and satiety, aiding in overall wellness and weight management.

Protein Content by Type and Preparation

Atlantic salmon is renowned as a high-quality protein source, but its nutritional profile can vary slightly based on its origin and how it is prepared. As a general rule, a 3.5-ounce (100g) serving provides a substantial portion of an adult's daily protein requirement.

Raw vs. Cooked Protein Density

Cooking concentrates the protein in salmon by removing moisture, meaning a fillet's protein content per gram will be higher after cooking than before.

  • Raw Farmed Atlantic Salmon: Contains approximately 20 grams of protein per 100g (3.5 oz).
  • Raw Wild Atlantic Salmon: Contains around 20.5 grams of protein per 100g.
  • Cooked Farmed Atlantic Salmon: A 6 oz (approx. 170g) portion contains about 34.6 grams of protein, reflecting a higher concentration after moisture loss.

Farmed vs. Wild Salmon

While protein content is comparable in total mass, the fat-to-protein ratio differs significantly between farmed and wild salmon.

  • Farmed Salmon: Typically has a higher total fat content, leading to a richer, milder flavor and softer texture. This means wild salmon can offer a higher protein-to-calorie ratio.
  • Wild Salmon: Possesses leaner, firmer flesh and a more intense flavor. Although its total fat is lower, it has a more balanced omega-3 to omega-6 fatty acid ratio.

Atlantic Salmon vs. Other Protein Sources

To put Atlantic salmon's protein content into perspective, here is a comparison with other common protein sources, based on a 100g serving size.

Protein Source (100g) Protein (g) Fat (g) Omega-3s (g)
Farmed Atlantic Salmon ~21.6g ~15.2g ~2.3g
Wild Atlantic Salmon ~25g ~8g ~2.2g
Chicken Breast (skinless) ~19.6g ~2.2g 0.1g
Beef Mince ~20.3g ~15.3g ~0.1g
Tilapia ~20g ~4.5g ~0.5g
Wild Trout ~22.3g ~5.8g ~0.7g

Key Nutritional Benefits of Atlantic Salmon

Beyond its high-quality protein, Atlantic salmon is a nutrient-dense food with several other health-promoting components.

  • Omega-3 Fatty Acids (EPA and DHA): Supports heart health by decreasing inflammation and can improve brain function.
  • Rich in B Vitamins: An excellent source of B12, B6, niacin, and other B-complex vitamins essential for energy production and neurological function.
  • Vitamin D: One of the few natural dietary sources of vitamin D, which is crucial for bone health.
  • Selenium: Provides a significant portion of the daily value for this mineral, which plays a role in thyroid hormone metabolism and immune health.
  • Potassium: Contains more potassium per gram than a banana, helping to regulate blood pressure.
  • Antioxidant (Astaxanthin): The compound responsible for salmon's characteristic pink color, astaxanthin has powerful antioxidant properties.

Conclusion

In summary, Atlantic salmon is an exceptional source of high-quality, complete protein, providing roughly 20 to 25 grams per 100g serving depending on whether it's wild or farmed and its preparation. Its rich protein content is complemented by a comprehensive profile of essential nutrients, including heart-healthy omega-3s, crucial B vitamins, and powerful antioxidants. Regular consumption of Atlantic salmon can significantly contribute to muscle maintenance, bone density, and overall wellness.
