Of the different sources of protein that you can include in your diet, fish is considered one of the most complete foods.
Not only does it contain high-quality protein, it also provides vitamins A, B and D, minerals such as phosphorus, magnesium and selenium, as well as iodine (in saltwater fish). It is also
a food that is generally lower in saturated fat, carbohydrates and cholesterol than red meat.
Some fish such as tuna, salmon, mackerel and sardines are high in omega 3’s and provide different health benefits. As a recent study referenced by the Food and Agriculture Organization of the United Nations (FAO) states, “The fats in certain fish are a better source of the fat that is needed for the normal development of the brain in unborn children and newborns. Without enough of these fatty acids, normal brain development does not occur.”
“On average, the daily dietary contribution of fish is rather low in terms of calories, at about 33 calories per capita.” (FAO).
