Why do you need food to live?

Answer 1

We need food in the same way that a car needs petrol or fuel. Our body uses up energy everyday, not only to walk or exercise but for everything, your body is still using up fuel when it's asleep as your heart and other organs are still working hard.

Food contains not only these essential fuels but also other nutrients which help to keep our bones, hair, nails and skin strong and supple. It also contains other goodness which helps to keep our immune system strong and keeps us fit and healthy.

Food is what the body uses for "fuel". Without food the body could not pump the heart, breathe and all the other essential parts of existing. People who do not eat very much find they are tired from small tasks like walking because the body has no fuel to make your legs move.

The body also requires a range of chemicals to keep certain organs alive and to keep the correct balance in the body. These chemical are taken from the food we eat. This is why people have organ failure if they are not eating properly.
