Most types of salmon has around 29 grams of protein per 4 ounce grilled fillet. Atlantic salmon fits into this range. If you prefer farm-raised salmon, however, you won’t get quite as much protein. For example, farm-raised Atlantic salmon has fewer than 22 grams of protein in a 4 ounce cooked piece, but you’ll get more than 24.5 grams from the same amount of the wild variety.
A 4 ounce portion of beef sirloin steak with the fat trimmed off contains about 34 grams of protein.
A 4 ounces of grilled chicken contain about 36 grams of protein.
Since chicken, beef and fish are an animal/poultry protein, they contain all of the essential amino acids you require on a daily basis to build proteins within your body.
