Conceptos alimentarios básicos: las proteínas

Proteins are vital for growth, oxygen transport, and various bodily functions. They consist of amino acids, which are essential for protein diversity. Our body requires essential amino acids from our diet. Proteins are broken down into amino acids during digestion, which are then used for cell repair, metabolism, and enzyme production. They also serve as an energy source, highlighting the importance of a protein-rich diet.
