Understanding the Calorie Differences in Raw Salmon
The number of calories in a piece of raw salmon is not a fixed figure. It varies primarily based on whether the fish is wild-caught or farmed, with a notable difference in fat and protein content between the two. Understanding these distinctions is crucial for accurate nutritional tracking. While both varieties offer high-quality protein and heart-healthy omega-3 fatty acids, their individual calorie profiles are determined by their diet and environment.
Wild-Caught vs. Farmed Raw Salmon: A Nutritional Breakdown
The primary factor influencing the calorie count of raw salmon is its origin. Wild-caught salmon, which spend their lives swimming freely and eating a natural diet of smaller fish, krill, and plankton, are leaner than their farmed counterparts. Farmed salmon, on the other hand, live in confined spaces and are given a high-fat, high-protein diet to promote rapid growth, resulting in higher fat content and, consequently, more calories.
- Wild Salmon: A 3.5-ounce (100g) serving typically contains around 136-182 calories. This leaner profile is often accompanied by slightly higher levels of certain minerals, such as calcium and iron.
- Farmed Salmon: A 3.5-ounce (100g) portion of farmed salmon usually has more calories, ranging from 206 to 238 calories, due to its higher fat content. These fish can also contain higher levels of certain vitamins and beneficial fats, as their feed is often fortified.
How Portion Size Affects Calorie Intake
When consuming raw salmon, especially in dishes like sushi or sashimi, portion size is a critical determinant of total calorie intake. A single piece of salmon sashimi is often small and can vary in size. For precise tracking, it's best to measure by weight. The standard nutritional information is based on a 3-ounce (85g) or 3.5-ounce (100g) serving. A typical 1-ounce piece of raw Atlantic salmon contains approximately 59 calories. A thin slice used for sashimi may be closer to 40 calories.
Example Portion Sizes & Estimated Calories
- Small Sashimi Slice (approx. 0.5 oz): ~25-30 calories
- Standard Sashimi Slice (approx. 1 oz): ~50-60 calories
- Standard 3 oz Serving (85g): ~121-175 calories (depending on wild vs. farmed)
- Standard 100g Serving: ~136-238 calories (depending on wild vs. farmed)
Raw vs. Cooked Salmon Calories
The raw calorie count provides a baseline, but cooking methods can alter the final energy content. Cooking itself doesn't significantly change the base calorie amount of the fish itself, but it can change the weight. The most substantial change comes from added fats during preparation, such as oils or butter. For instance, an ounce of raw salmon might be 58 calories, while a cooked ounce could be around 60 calories due to water loss, but adding a tablespoon of oil can add another 120 calories.
To keep calories low, minimal-fat cooking methods like poaching or baking are recommended.
Comparison Table: Wild vs. Farmed Raw Salmon (per 100g)
| Nutrient | Wild Salmon | Farmed Salmon |
|---|---|---|
| Calories | 136–182 kcal | 206–238 kcal |
| Protein | 22–25 g | 20–22 g |
| Fat | ~5–8 g | ~12–15 g |
| Omega-3s | Good source | Excellent source |
| Vitamins (e.g., B12, B6) | Excellent source | Excellent source |
| Sodium | Lower | Higher |
The Health Benefits of Raw Salmon
Regardless of its calorie count, raw salmon offers a wealth of nutritional benefits. It is one of the best sources of the long-chain omega-3 fatty acids, EPA and DHA, which are crucial for brain health and reducing inflammation. Its high protein content supports muscle maintenance and can promote feelings of fullness, aiding in weight management. It is also packed with essential vitamins, including the full range of B vitamins and a significant amount of Vitamin D. Antioxidants like astaxanthin, which give salmon its pink color, also provide powerful health effects.
Considerations for Safely Eating Raw Salmon
While raw salmon is nutritious, it is important to consume it safely to avoid parasites and bacteria. When preparing raw salmon, always purchase high-quality fish from a reputable supplier known for selling fresh seafood. To kill any potential parasites, the FDA recommends freezing fish at -4°F (-20°C) for at least 7 days before eating it raw. Proper hygiene, including using clean utensils and washing hands thoroughly, is essential to prevent cross-contamination.
Conclusion: How Many Calories Are in a Piece of Raw Salmon?
So, how many calories are in a piece of raw salmon? The answer depends on two main factors: its origin and the size of the piece. Wild-caught salmon is leaner, with fewer calories, while farmed salmon contains more fat and, therefore, more calories. For a standard 3-ounce portion, wild salmon has approximately 121 calories, while farmed salmon has about 175 calories. To accurately track your intake, measure by weight and consider the fish's source. Overall, raw salmon is a highly nutritious and healthy food choice, providing essential omega-3 fatty acids, high-quality protein, and valuable vitamins and minerals, whether you're enjoying it as sashimi or in a poke bowl.

Frequently Asked Questions
How many calories are in a piece of salmon sashimi?
A piece of salmon sashimi can contain anywhere from 25 to 60 calories, depending on its size and thickness. A thin slice is on the lower end, while a thicker, more substantial piece will have more calories.
Is wild or farmed raw salmon higher in calories?
Farmed raw salmon is typically higher in calories than wild raw salmon. This is because farmed salmon have a higher fat content due to their controlled diet and environment, while wild salmon is leaner.
Does cooking salmon change its calorie count?
Cooking does not fundamentally change the base calories of the salmon itself, but the cooking method can affect the final calorie count. Methods like pan-frying with oil or butter add significant calories, while poaching or baking with minimal additions keeps the calories low.
How many calories are in raw salmon skin?
Salmon skin contains more omega-3 fatty acids, fat, and protein than the meat itself. However, it is richer and is often prepared with extra oil or salt, adding calories. A small, crispy portion of skin will contribute extra calories and healthy fats to your meal.
Is raw salmon a good source of protein?
Yes, raw salmon is an excellent source of high-quality protein. A 3.5-ounce (100g) serving of wild salmon can provide around 22–25 grams of protein, offering all the essential amino acids your body needs.
Is it safe to eat raw salmon every day?
While raw salmon is nutritious, it is not recommended to eat it every day due to the potential risk of parasites and bacteria. For pregnant women, young children, older adults, and those with weakened immune systems, consuming raw seafood should be avoided altogether. For healthy adults, it is best to limit raw fish intake and ensure the salmon is properly prepared and handled.
What nutrients are in raw salmon besides calories?
Beyond calories, raw salmon is packed with essential nutrients, including heart-healthy omega-3 fatty acids (EPA and DHA), high levels of protein, B vitamins (especially B12, B6, and niacin), Vitamin D, and minerals like selenium and potassium.
Can raw salmon help with weight loss?
Yes, raw salmon can be beneficial for weight management. Its high protein content and healthy fats promote satiety, helping to regulate appetite and prevent overeating. Additionally, the omega-3s may help reduce belly fat in combination with an active lifestyle.
