What is Protein and Why is it Important?
Protein is a macronutrient consisting of amino acids that are essential for the body’s growth, repair, and maintenance. The importance of protein cannot be overstated. It serves various functions, including:
- Building and repairing tissues
- Producing enzymes and hormones
- Supporting immune function
- Transporting nutrients
- Providing energy when carbohydrates are insufficient
How Much Protein Do I Need Based on Age?
Your age plays a crucial role in determining your protein requirements. Here's a breakdown:
