First, let us note that canned sardines are a good source of calcium. This mineral is present in the edges of sardines which must be savored as is. In addition, each 100g of sardines provide almost the equivalent of half a glass of milk in calcium.
– Sardines belong to the family of fatty fish. As such, they are rich in fat, mainly in Omega 3 which is beneficial for the cardiovascular system.
– Canned sardines that are soaked in oil are almost twice as caloric as fresh sardines. In fact, 100g of sardines in oil provide some 200 Kcal. Thus, oil-free sardines that are canned with lemon are a much less caloric alternative.
– Sardines are a good source of vitamins (D and B12 essentially) and of minerals including calcium of course, as well as iron, zinc, and copper.
– The content of sodium in sardines varies from one brand to another. For this reason, washing sardines before consuming them can help reduce their sodium content.
– Finally, and for a better conservation and in order to preserve the flavor of sardines and their biological value, it is advisable to regularly turn sardine cans upside down.
