Why Protein Matters for Your Body

Protein is known as the building block of life because every cell in your body needs it. It is made up of amino acids that help your body grow, repair, and stay strong.

Protein plays an important role in:

• Building muscles and bones
• Repairing tissues and cells
• Strengthening immunity
• Producing hormones and enzymes
• Supporting healthy skin and hair
• Improving metabolism
• Maintaining energy levels 

Unlike fats and carbohydrates, your body does not store protein for future use. That means you need regular intake of protein-rich foods every day.

Both children and adults need enough protein, but it becomes especially important for athletes, growing children, pregnant women, older adults, and people recovering from illness.
