Omega 3
Omega-3 fatty acids are essential nutrients that the body needs to maintain healthy function but cannot produce on its own. Therefore, it is necessary to get Omega-3 through the diet, and salmon is one of the richest sources.
Although the fat content in a Skagen salmon is lower than in traditionally farmed salmon, the concentration of Omega-3 fatty acids is high. When the salmon swims against the current, muscle mass increases and the total fat content decreases. In this process, the saturated fatty acids - the unhealthy fat - are reduced and the concentration of Omega 3 fatty acids increases. This is because these polyunsaturated fats are a stable part of the fish's fatty acid profile.
The exercise thus results in a healthier fish with a lower total fat content, but still with a high level of the beneficial Omega-3 fatty acids.
