1. Building and Repairing Tissues:
* Protein is the building block of tissues, including muscles, bones, skin, hair, and nails.
* It's essential for growth and development, particularly during childhood and adolescence.
* It also helps repair damaged tissues after injury or illness.
2. Enzyme and Hormone Production:
* Enzymes are proteins that catalyze (speed up) biochemical reactions in the body.
* Hormones, like insulin and growth hormone, are also proteins that regulate various bodily processes.
3. Immune Function:
* Antibodies, which are crucial for fighting off infections, are made of protein.
* Protein is also needed for the production of white blood cells, which are the body's defenders against disease.
4. Energy Production:
* While protein is primarily used for building and repairing tissues, it can also be used as an energy source if carbohydrates and fats are not available.
5. Maintaining Fluid Balance:
* Protein helps regulate fluid balance in the body by attracting water to the blood.
6. Blood Clotting:
* Certain proteins, such as fibrinogen, are essential for blood clotting, preventing excessive bleeding.
7. Transporting Nutrients:
* Some proteins act as carriers, transporting nutrients like iron and oxygen throughout the body.
8. Maintaining pH Balance:
* Protein helps maintain the body's pH balance, keeping it within a healthy range.
9. Satiety and Weight Management:
* Protein can help you feel full and satisfied after eating, which can be beneficial for weight management.
10. Overall Health and Wellbeing:
* Adequate protein intake is essential for maintaining overall health and wellbeing, reducing the risk of chronic diseases and supporting healthy aging.
Important Note: The amount of protein you need varies depending on factors like age, activity level, and health status. Consulting with a healthcare professional or registered dietitian can help you determine your individual protein requirements.
