Here's why:
* Building blocks: Proteins are made up of amino acids, which are the building blocks for all cells, tissues, and organs in our body.
* Growth and development: During childhood and adolescence, protein is crucial for building new tissues and muscles.
* Repair and maintenance: Throughout life, protein helps repair damaged tissues, replace worn-out cells, and maintain healthy organs.
* Other functions: Proteins also have various other functions in the body, such as:
* Producing enzymes that facilitate chemical reactions.
* Forming antibodies to fight infections.
* Transporting oxygen and other nutrients.
While other nutrients like carbohydrates and fats are important for providing energy, protein plays a unique and vital role in growth, development, and repair.
