Mackerel, sardines, anchovies offer salmon's nutrition cheaply, especially in Spain

Cheaper alternatives like mackerel, sardines, and anchovies offer similar nutritional benefits to salmon, particularly Omega-3 fatty acids, at a lower cost. These "inshore fish" are rich in Omega-3, sometimes exceeding salmon's levels of 2.2 grams per 100 grams, and are more affordable, especially in Spain where salmon prices can reach 27 euros per kilo. A recent investigation highlighted the nutritional value of these alternatives, emphasizing their accessibility and the importance of considering origin and fishing methods when choosing seafood.
