Understanding Proteins

Proteins are essential nutrients known as the building blocks of the human body. They are crucial for various bodily functions, including chemical reactions, DNA production, and tissue repair. Proteins consist of 20 different amino acids, and complete proteins contain all of them. Foods like meat, fish, and eggs provide complete proteins. Alternatively, plant-based foods like grains and beans offer incomplete proteins, which can be combined to meet amino acid needs.
