Nutritional Profile: Mahi Mahi vs. Salmon
When comparing mahi mahi and salmon, the most significant difference lies in their fat content. Salmon is an oily fish, rich in heart-healthy omega-3 fatty acids, whereas mahi mahi is a lean fish with a firm, white flesh. This fundamental distinction leads to a host of other nutritional variations that can influence which fish is best for your dietary needs.
Fat Content and Omega-3s
Salmon's higher fat content is its most celebrated feature, particularly due to its abundance of long-chain omega-3s, specifically EPA and DHA. A 100-gram portion of salmon can contain over 2 grams of omega-3s, whereas the same serving size of mahi mahi has considerably less—around 100-200 mg. This difference is vital for anyone looking to increase their intake of omega-3s for cardiovascular or cognitive health benefits. While mahi mahi does contain some healthy fats, its quantity is far lower, classifying it firmly as a lean protein source rather than a fatty one.
Protein and Calories
Both fish are excellent sources of high-quality protein. However, due to its higher fat content, salmon is more calorically dense than mahi mahi. Per 100 grams, mahi mahi offers slightly more protein but at a much lower calorie count. For those prioritizing lean protein intake and weight management, mahi mahi can be a more suitable choice due to its lower energy density.
Vitamins and Minerals
While both fish provide a variety of micronutrients, salmon generally has a richer vitamin profile. It is especially notable for its high levels of B-complex vitamins, such as B12, B6, and niacin, as well as a significant amount of vitamin D. Mahi mahi, on the other hand, is a strong source of selenium, potassium, and phosphorus. The specific mineral content of both fish can vary based on wild vs. farmed sources and location.
Comparison Table
| Nutrient (per 100g raw) | Mahi Mahi | Salmon (Atlantic, Wild) | Key Difference | 
|---|---|---|---|
| Classification | Lean Fish | Oily/Fatty Fish | Fat Content | 
| Total Fat | ~0.7-1g | ~6-12g | Salmon is significantly higher | 
| Omega-3s (EPA+DHA) | ~100-200 mg | ~2,200 mg | Salmon has over 10x more | 
| Calories | ~85-109 kcal | ~142-206 kcal | Salmon is more calorically dense | 
| Protein | ~19-24g | ~20-22g | Both are excellent protein sources | 
| Vitamin D | Trace | Very high | Salmon is a top dietary source | 
Health Benefits of Each Fish
Both mahi mahi and salmon offer valuable benefits, but they cater to different dietary goals. Your choice depends on what you want to emphasize in your nutrition.
Here is a list of their respective benefits:
Mahi Mahi Benefits
- High in Lean Protein: Excellent for muscle building and satiety without a high caloric load.
- Low in Calories: A good choice for those managing their weight.
- Rich in Selenium: An important antioxidant that supports immune function.
- Good Source of B Vitamins: Contains Vitamin B12, B3, and B6.
- Relatively Low in Mercury: Generally considered a low-mercury option, making it safer for more frequent consumption.
Salmon Benefits
- Abundant Omega-3s: Exceptional for heart health, reducing inflammation, and brain function.
- Rich in Vitamin D: One of the few natural food sources of this crucial vitamin.
- High in B-Complex Vitamins: Supports energy production and cellular health.
- Contains Astaxanthin: An antioxidant carotenoid that gives salmon its pink color and offers additional health benefits.

Conclusion
To conclude, mahi mahi is not a fatty fish like salmon. While salmon is prized for its high fat content and exceptional omega-3 levels, mahi mahi offers a lean, protein-rich alternative. The best choice depends on your specific nutritional needs. If you are focused on maximizing your omega-3 intake and don't mind the extra calories, salmon is the clear winner. However, if your goal is a high-protein, low-calorie option, or if you are concerned about mercury levels, mahi mahi is an excellent and healthy choice. Both can be part of a balanced and nutritious diet, providing a range of essential vitamins and minerals.
