Proteins are essential nutrients for the human body. They are one of the building blocks of body tissue and can also serve as a fuel source.Proteins are made of amino acids...

Humans can’t survive without all nine essential amino acids. Protein is essential to building bones,and body tissues, such as muscles, but protein does much more than that. Protein participates in practically every process of a cell. It plays a part in metabolic reactions, immune response, protein provides a source of energy, assists in cellular repair, form blood cells, and more.

Both plants and animals provide good sources of protein. It’s important to be aware, however, that while many plants provide protein, most do not provide all of the essential amino acids. According to the Food and Nutrition Board of the Institute of Medicine, meat, poultry, fish, eggs, milk, cheese, yogurt, quinoa, and soybeans are all source of complete protein – which means they provide all nine essential amino acids.
