Protein is crucial for the growth, repair, and maintenance of body tissues, especially muscles. Including sufficient protein in your diet can aid in muscle development and support various physiological processes.

However, individuals with specific health conditions, such as hypercholesterolemia, should monitor their cholesterol intake.

Sodium and Potassium Balance
