Why Is Protein Important in Our Diet?
Why Is Protein Important in Our Diet?
Protein is essential for our diet because it plays a critical role in building and repairing tissues, supporting immune function, and producing hormones and enzymes. Additionally, protein provides energy and helps maintain muscle mass.
According to the World Health Organization (WHO), protein is defined as a macronutrient made of amino acids that the body needs for various functions, including growth and bodily repair.
The importance of protein can be broken down into several key reasons:
-
Muscle Repair and Growth: Protein helps repair damaged muscle tissues after exercise. After resistance training, protein intake contributes to muscle hypertrophy, which is an increase in muscle size.
-
Enzyme Function: Proteins act as enzymes that facilitate biochemical reactions. Enzymes are crucial for processes such as digestion and metabolism.
-
Immune Response: Proteins are vital for producing antibodies. Antibodies help detect and neutralize foreign invaders like bacteria and viruses, thus supporting the immune system.
-
Transport and Storage: Certain proteins, such as hemoglobin, transport oxygen throughout the body. Others store essential nutrients for later use.
Technical terms like ‘amino acids’ refer to the building blocks of proteins. The body requires 20 different amino acids to function properly, with nine of them deemed essential, meaning they must be obtained from food.
When we consume protein, the body breaks it down into amino acids through digestion. This process occurs primarily in the stomach and small intestine. Once the amino acids are available, they enter the bloodstream and are used for various bodily functions, including muscle repair, hormone production, and immune responses.
Specific actions contribute to the need for adequate protein intake. Athletes may require higher protein levels to support muscle repair due to their rigorous training. Older adults also need more protein to prevent muscle loss or sarcopenia, a condition characterized by the gradual loss of muscle mass. A well-balanced diet that includes sources such as meat, fish, eggs, dairy, legumes, nuts, and seeds is vital for obtaining sufficient protein.
