Why are sardines called blue fish?
Sardines are categorized as “blue fish” (even if it’s not the scientific classification) because they are generally small- to medium-sized fish with a dark blue color on their backs and a silvery hue on the belly. Traditionally, blue fish have been considered a part of peasant cuisine in Italy, but more recently, they’ve been revalued by nutritionists for the high content of essential nutrients that contribute to health. Sardines in particular, typical of the Mediterranean Sea, are rich in good fats and therefore super recommended as part of a balanced diet – Mediterranean diet anyone?
