Food Basics: Proteins

Proteins are vital for various bodily functions, including muscle formation, oxygen transport, and hair and nail growth. They are found in foods like eggs, dairy, beans, and nuts. Proteins consist of amino acids, with 22 types contributing to their diversity. Eight essential amino acids must be obtained through diet. Digestion breaks proteins into amino acids, which are absorbed and reassembled in the body. Proteins are crucial for metabolism, growth, and immune function, and they serve as enzymes and energy sources.
