What are proteins

Proteins is called the macro nutrient, it's one of the big three along with carbohydrate and fat.

Macro means large

and protein is a macro nutrient because you needed in larger amounts compared to vitamins and minerals ( Which are called micro nutrients ).

The protein that you eat is made up of little building blocks called amino acids.

When you digest your protein

those amino acids are used by your body to manufacture important proteins within your body

and

because your body doesn't store protein

it's really important that you get enough protein in your diet every single.
