Protein

Protein is a macronutrient that is required for muscular growth. It is most typically found in animal products, although it may also be found in nuts as well as legumes. Amino acids, which are organic molecules formed of carbon, hydrogen, nitrogen, oxygen, or sulphur, make up protein chemically. Proteins are made up of amino acids, and proteins are the building blocks of muscle mass. When protein is broken down in the body, it aids metabolism by fueling muscular mass. Protein should account for 10 to 35 percent of daily calories, according to the Institute of Medicine.
