Which nutrients are essential for growth and repair of muscle and other body tissues ?
Proteins
Proteins are made of amino acids, which are the building blocks of muscle fibres, enzymes, hormones and nearly all body tissues; hence proteins are called body-building foods.
During growth and after exercise or injury, amino acids from dietary protein are used to synthesise new tissue and repair damaged muscle.
Minerals and vitamins act mainly as regulators of body processes, and roughage (fibre) aids digestion; none of these builds tissue.
Hence, the answer is Proteins.
