A Closer Look at the Macros of an Ounce of Salmon
Salmon is widely celebrated for its rich nutritional profile, particularly its high content of lean protein and heart-healthy omega-3 fatty acids. When analyzing the macros for a small 1-ounce portion, it's important to consider that nutritional values can vary based on several factors. The species of salmon (e.g., Atlantic, Sockeye, Pink) and how it's prepared (raw, cooked, wild, or farmed) all affect the final macronutrient breakdown. Regardless of the type, an ounce of salmon is a low-calorie, zero-carb, and protein-packed food.
Wild vs. Farmed Salmon: A Macro Comparison
The difference between wild-caught and farmed salmon is the most significant variable in its macronutrient content. This is primarily due to differences in diet and activity levels between the two environments. Farmed salmon is often higher in fat and calories, while wild-caught salmon tends to be leaner and higher in protein. However, both offer substantial health benefits and are excellent sources of essential nutrients like omega-3s, selenium, and B vitamins. For instance, wild Atlantic salmon has been noted to contain approximately 1 gram of omega-3s per ounce, a significant amount for such a small serving.
Macronutrient Breakdown by Salmon Type (per ounce)
| Macro | Wild Atlantic (Cooked) | Farmed Atlantic (Raw) | Sockeye (Raw) |
|---|---|---|---|
| Calories | ~52 kcal | ~59 kcal | ~40 kcal |
| Protein | ~7 g | ~6 g | ~6 g |
| Fat | ~2 g | ~4 g | ~2 g |

The Micronutrient Powerhouse in Salmon
Beyond its impressive macro ratios, salmon is a rich source of various vitamins and minerals, even in a small 1-ounce serving. These micronutrients play vital roles in overall health, from supporting brain function to maintaining bone density. A single ounce can provide a notable percentage of your daily intake for key nutrients.
- Vitamin B12: Essential for nerve function and red blood cell production, salmon is a fantastic source. One ounce of wild Atlantic salmon provides approximately 36% of the daily value for Vitamin B12.
- Selenium: This mineral acts as a powerful antioxidant, protecting the body from cellular damage. An ounce of cooked, wild Atlantic salmon offers around 24% of the daily value.
- Vitamin D: Salmon is one of the few natural food sources of vitamin D, which is crucial for calcium absorption and bone health. Wild sockeye salmon is particularly rich in this vitamin.
- Niacin (Vitamin B3): Important for energy metabolism and DNA repair, a small serving of salmon contains a significant amount of this B vitamin.
Incorporating Salmon into a Macro-Focused Diet
For individuals tracking their macros, a small portion of salmon is a highly efficient and versatile food. Its high protein content supports muscle repair and growth, while the healthy fats provide sustained energy and support satiety. Since it has zero carbohydrates, it's a perfect fit for ketogenic or low-carb eating plans. Here are some simple ways to incorporate a small portion into your diet:
- Quick Salad Topper: Flake a small, cooked piece of salmon over a bed of mixed greens for a protein boost.
- Mini Salmon Cakes: Mix flaked salmon with a small amount of binder (like a low-carb flour alternative) and seasoning to create miniature, protein-rich patties.
- Breakfast Scramble: Add a half-ounce of chopped, smoked salmon to eggs for a savory, nutrient-dense breakfast.
- Light Snack: Serve a few small pieces of leftover cooked salmon on cucumber slices with a dollop of Greek yogurt.
The Value of a Small Serving
Even in a small quantity, the health benefits of salmon are substantial. It provides a dense source of high-quality protein and beneficial fats, especially the omega-3s EPA and DHA, which are linked to reduced inflammation and improved cardiovascular health. A single ounce can contribute meaningfully to your daily nutritional goals without a significant caloric impact. This makes it an ideal ingredient for meal prepping, calorie-controlled diets, or simply adding a healthy protein source to a snack.
Conclusion
An ounce of salmon is a concentrated nutritional powerhouse, offering a balanced and impressive profile of protein and healthy fats with no carbohydrates. While the specific calorie and fat content can vary between wild and farmed varieties, both are excellent sources of essential nutrients like omega-3 fatty acids, B vitamins, and selenium. Its versatility and dense nutritional content make it a valuable addition to nearly any eating plan, proving that good things really do come in small packages when it comes to this popular fish.
