1. Why Is Healthy Protein So Important For Your Body?
Healthy protein is essential because it serves as the fundamental building block for the body’s tissues, enzymes, and hormones, crucial for muscle repair, immune function, and overall health. Proteins are vital for various bodily functions, including the creation of enzymes and hormones that regulate metabolism, the maintenance and repair of tissues, and the support of a healthy immune system.
