The body needs protein because it plays a critical role in many bodily functions: it is essential for building and repairing tissues (muscles, bones, skin), making enzymes and hormones, supporting digestion, and producing energy. Protein also helps maintain bone density, supports muscle mass, aids in wound healing, and regulates various biological processes. Since protein is made of amino acids, some of which the body cannot produce and must be obtained from food, sufficient daily intake is vital for health, growth, and repair. Additionally, protein can help with appetite control and weight management by making people feel full longer after meals.
Key reasons why protein is needed:
- Major building block for muscles, bones, skin, hair, and nails.
- Essential for enzyme and hormone production.
- Critical for tissue repair and cell regeneration.
- Helps maintain bone strength.
- Supports immune function and red blood cell oxygen transport.
- Contributes to digestion and metabolic processes.
- Assists with appetite control and weight management.
Thus, protein is indispensable for overall body function, health maintenance, and recovery throughout life.
