Which food type is essential for building and repairing tissues?

Proteins are essential for building and repairing tissues because they are made up of amino acids, which serve as the building blocks for various structures in the body. When we consume proteins, they are broken down into these amino acids during digestion. Our bodies then use these amino acids to create new proteins necessary for growth and repair of muscles, skin, organs, and other tissues. This function is vital not only for everyday maintenance of body tissues but also for healing after injuries and supporting overall health.

Other food types also play important roles: fats provide energy and support cell structure, carbohydrates are primarily energy sources, and minerals are necessary for various biochemical processes but do not directly contribute to tissue building and repair like proteins do.
