Protein is essential for repairing tissues in the body, playing a crucial role in muscle recovery and growth after physical exercise. It consists of amino acids that serve as building blocks for new tissue formation, aiding in the healing of wounds and injuries. Protein also supports other bodily functions, such as producing enzymes and hormones. Adequate intake of protein-rich foods, including lean meats, dairy products, legumes, and nuts, is vital, particularly for active individuals or those recovering from surgery or injury.
