What is the main function of proteins in the body?

Provide energy
Support bone health
Build and repair tissues
Regulate blood sugar

The correct answer is: Build and repair tissues

Proteins play a crucial role in the body primarily through their function in building and repairing tissues. They are made up of amino acids, which are the building blocks necessary for the structure and function of all body cells. When the body undergoes growth, muscle development, or recovery from injury, proteins are integral to the process. This includes repairing muscles after exercise, healing wounds, and even supporting the production of enzymes and hormones that are vital for numerous biological functions. While proteins can serve as a secondary energy source, their primary function is not energy provision. Instead, carbohydrates and fats are typically utilized first for energy needs. Additionally, while proteins can have some influence on bone health and blood sugar regulation, these are not their main roles. Focused primarily on tissue synthesis, repair, and maintenance, proteins are essential for overall growth, development, and bodily function.
