The support calories provide to the human body

The average pizza slice has 272 calories,there are about 78 in a piece of bread,and an apple has about 52.That energy is released during digestion,and stored in other molecules that can be broken down to provide energy when the body needs it.It's used in three ways:about 10% enables digestion,about 20% fuels physical activity,and the biggest chunk, around 70%,supports the basic functions of our organs and tissues.
