Protein is an essential macronutrient that plays a crucial role in the structure, function and growth of the body. It is composed of amino acids, which act as building blocks for cells, tissues and organs. Protein is involved in a number of biological processes, including muscle building, immune function, enzyme function and transportation of nutrients.
The human body requires an adequate intake of protein through the diet, as it cannot produce all the necessary amino acids itself. Food sources rich in protein include meat, fish, eggs, dairy products, legumes, nuts and seeds. The amount of protein needed varies depending on individual factors such as age, activity level and health status. Maintaining a balanced diet containing adequate amounts of protein is essential to support growth, repair and maintenance of the body's structures and functions.
