Trout is a freshwater fish belonging to the Solomon family. It includes both populations living exclusively in the freshwaters, as well as populations living in the sea (sea-going) and then going back to the rivers. The trout contains high amounts of phosphorus, magnesium, vitamin A and omega-3 fatty acids, with many beneficial properties for the heart, other peripheral vessels and the brain. Ω-3 fatty acids have a positive effect on many different systems in our body and help reduce cholesterol and triglycerides.
