The exact number of calories in 100g of uncooked salmon is not a single, fixed number but rather a range that depends heavily on the type of salmon. Specifically, the distinction between wild-caught and farmed salmon is the most significant factor affecting its caloric content. This article will delve into the caloric differences, the reasons behind them, and provide a full nutritional breakdown of each type.
Calorie Differences Between Wild and Farmed Salmon
Research indicates a notable contrast in caloric density between the two main types of salmon. Farmed salmon is known to contain higher levels of fat, which directly translates to a greater number of calories per serving. This is because fish farms are designed to promote rapid growth, often through high-fat feed, and the confined environment requires less energy expenditure from the fish. As a result, farmed salmon accumulates more intramuscular fat.
Conversely, wild salmon has a leaner profile. It spends its life migrating and foraging in the wild, which leads to a more active lifestyle and a lower overall fat content. This results in a fewer calories per 100g serving.
Nutritional Breakdown Per 100g
| Nutrient | Wild Atlantic Salmon (approx.) | Farmed Atlantic Salmon (approx.) | 
|---|---|---|
| Calories | 142 kcal | 203-208 kcal | 
| Total Fat | ~6g | ~13g | 
| Protein | ~20g | ~20-22g | 
| Omega-3s | ~2g | ~3g | 
| Saturated Fat | ~1g | ~3g | 
| Vitamin B12 | Excellent Source | Excellent Source | 
| Selenium | Excellent Source | Excellent Source | 
Why the Calorie Count Varies
- Diet: The diet of farmed salmon is carefully controlled and engineered to maximize growth, often including fishmeal and oils, which results in higher fat accumulation. Wild salmon's diet is more varied, consisting of smaller fish, crustaceans, and plankton, which contributes to its leaner body composition.
- Environment: Wild salmon swim long distances, migrating upstream to spawn. This highly active lifestyle burns more calories and keeps their fat stores lower. Farmed salmon are raised in pens with limited space, leading to a more sedentary existence and higher fat content.
- Omega-3 Content: While farmed salmon can be higher in total fat, it does not necessarily mean it is superior in all nutritional aspects. While it can be richer in omega-3 fatty acids due to diet manipulation, the ratio of omega-3 to omega-6 fatty acids can differ between wild and farmed varieties. Both remain excellent sources of healthy fats, but their specific nutrient compositions are a result of their respective lifestyles.
- Species Differences: Within the wild salmon category, species like sockeye, king, and coho also have varying calorie and fat contents. However, the largest and most common distinction is between wild and farmed salmon, particularly Atlantic salmon, which is almost exclusively farmed.
The Role of Cooking Method
The cooking method can also significantly impact the final calorie count of your salmon dish. Frying salmon in oil or butter will add extra calories, while poaching, baking, or grilling will preserve its natural calorie profile. For example, a 100g piece of wild salmon that is baked with a squeeze of lemon will retain its initial calorie count, whereas pan-frying it in 1 tablespoon of olive oil (about 120 calories) will add to the total.
To calculate the calories in cooked salmon accurately, you should:
- Start with the base uncooked calorie count.
- Add the calories from any oils, butter, or marinades used.
- Note that cooking does not increase the calorie count of the fish itself, only the added ingredients.
Conclusion
To determine how many calories are in 100g of uncooked salmon, you must first identify if it's wild or farmed. For wild salmon, you can expect around 142 calories per 100g, while farmed salmon typically contains about 203 to 208 calories. Both varieties are excellent sources of protein and heart-healthy omega-3s, but their fat and calorie content differ based on their environment and diet. Understanding these distinctions helps in making informed dietary choices.

Healthy Recipe Ideas with Salmon
- Simple Baked Salmon: Place salmon fillet on a baking sheet, season with salt, pepper, and lemon slices. Bake at 400°F (200°C) for 12-15 minutes.
- Grilled Salmon Salad: Grill a wild salmon fillet and flake it over a bed of mixed greens, cherry tomatoes, and cucumber. Top with a light vinaigrette.
- Poached Salmon: Gently poach salmon fillets in simmering water or broth with herbs until cooked through. This method keeps the fish moist without adding fat.
- Salmon and Veggie Skewers: Cube salmon and your favorite vegetables (like bell peppers and onions), thread them onto skewers, and grill or bake until done.
- Salmon Sashimi: For the lowest calorie preparation, enjoy high-quality wild salmon as sashimi. Ensure the fish is sushi-grade and properly handled for raw consumption.
Weight Management and Salmon
Incorporating salmon into a weight management plan is highly effective. Its high protein and healthy fat content contribute to a feeling of fullness, which can help control appetite and reduce overall calorie intake. Additionally, the omega-3s found in salmon have been linked to potential weight loss benefits, including a decrease in belly fat, particularly when combined with an active lifestyle. The moderate calorie count, especially in wild salmon, makes it an excellent choice for a satisfying and nutritious meal.
Choosing the Right Salmon for You
When selecting salmon, your choice between wild and farmed depends on your nutritional priorities and budget. Wild salmon offers a leaner, more naturally sourced option with potentially higher mineral content. Farmed salmon, while higher in fat and calories, is often more affordable and widely available. Both provide significant health benefits, especially regarding protein and omega-3 fatty acids. The best choice is the one that fits your dietary needs and lifestyle, and incorporating either into your meals is a step toward a healthier diet.
