Fish – an indispensable source of complete protein, which biological value it is close to the protein of meat products, but it has a higher degree of digestibility. Protein (protein) contains essential amino acids, some of which the body is unable to synthesize, and the only source of these amino acids, the protein in the diet.
Athletes and people sitting on protein diet, need foods with lots of protein at a low calorie product, it is necessary to give preference to tuna. So, in 100 g of this valuable fish contains an average of about 20-25 grams of complete protein, that is 50% of the daily value. Some species of this fish – yellowfin tuna, white tuna "albacore" and deep golubiy tuna contain almost 30 grams of protein. In second place after the tuna's protein content is halibut, anchovies, eel and tilapia – about 26-28 g. a Little behind them, the side 19 d and the mullet is 18.5 g Protein of mullet contains the essential amino acid methionine, which is not even in the protein of meat products.
Slightly behind the sides on the amount of protein mackerel (mackerel) – this fish, which in ancient times was called the "elixir of youth", contains about 18 grams of protein. On the same level is the amount of protein in the pike. Almost on a par with marine fish in protein content and are a noble freshwater sturgeon family: sturgeon, starred sturgeon, starlet and barbel sturgeon, Beluga. The protein content in 100 g of this fish reaches up to 16.5 g, but we must remember that the important source of protein can be not only meat but also eggs and milt. Moreover, the amount of protein in eggs is superior to protein in fish meat, and in Molokai – is equal to this value. Salmon and caviar – not less valuable source of protein. So, rainbow trout, chum salmon, pink salmon, salmon, whitefish, Chinook salmon, whitefish, grayling, taimen, sockeye salmon can contain from 16 to 20 grams of protein. The greatest number of different protein salmon – about 20 Gold a piece of salmon provides the human body with half the daily requirement of protein.
Meat of turbot contains 15.7 g of digestible protein with a well-balanced set of essential amino acids. Almost at the same level contains protein in cod, swordfish and fish of the family Cyprinidae: carp, carp, saber fish, tench, crucian carp, IDE. Hake, Pollock, nototenia, herring, cod, river and sea perch complete list of fish with high protein content.
