Why do we eat food?

                                                 Why do we eat food?

The question may sound funny. Everyone tell the answer as "to live". But scientifically speaking, the answer is not just that.
Our body is made of tiny and numerous cells. The work of cells is to produce energy. This energy is very essential for our daily activities.
How do cells produce energy? They require  glucose and oxygen for that purpose. Oxygen we will get from breathing. But what about glucose? The food we consume, will finally get reduced to glucose.
Patients are always advised to take glucose as an instant way to produce energy. It would be the instant way. But what we consume food is also get reduced to glucose. That's why we eat food.
