When it comes to fish, salmon is at the top of its class. Not only is it flavorful and filling, but it's also a high-quality protein and healthy fat source. Per ounce, salmon contains about 7 grams of protein, less than 1 gram of saturated fat and a hefty dose of the omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). EPA and DHA play an important role as an anti-inflammatory agent; they promote fat as fuel during exercise, and may promote fat loss and muscle protein synthesis.
As a runner, this means you can perform at your best for a longer period of time. You'll be less likely to hit a wall, and your body can use your fat stores as energy when your carb stores run out. Omega-3s EPA and DHA also contribute to a decrease in recovery time. That means that when you run on consecutive days, you won't feel as much fatigue.
