What is Protein?
Protein is an essential nutrient for making various parts of the human body such as muscle, internal organs, skin, nails, hair, etc. It is mainly composed of amino acids. Proteins can be classified into two types, “animal protein” and “vegetable protein”. “Animal protein” is contained in animal food such as meat, fish and shellfish, egg, dairy products, “vegetable protein” is contained in vegetable foods such as beans and cereals in large amounts. Both are proteins, but since the type and amount of amino acids making it are different, let’s eat foods containing each protein in a balanced way.
When it is digested, it is decomposed into amino acids, and proteins and enzymes that become materials for muscle, internal organs, skin, etc. are made in the body.
