How the Body Uses Its Food Energy?

The human body is incredibly complex. Every second, millions of physiological and chemical reactions take place in order to maintain good health. The body both creates things (eg. heat, muscle, proteins, RNA, hair, nails, enzymes, fat tissue, and bones) and breaks things down (food, stored fat, etc.). These anabolic and catabolic processes, along with all organs and systems, need fuel to enable them to function. The fuel or energy that the body uses comes from the food and drink that we consume in our diet. In a nutshell, food is human gasoline.
