Example of text

When we need food, our body begins to crave for it. But how do we know that we are hungry? How does our mind get the message and make us feel hungry? Hunger has nothing to do with an empty stomach, as most people believe. A baby is born with an empty stomach, yet it doesn’t feel hungry for several days. People who are ill often have empty stomach but don’t feel hungry. They just simply lose their appetite.

Hunger begins when the blood is getting out of some certain nutritive materials. When the blood vessels lack of these materials, a message is sent to a part of the brain that is called the “hunger center”. This part of the brain works like a brake in the intestine. As long as the blood has sufficient nutrition, the “hunger center” makes the intestine works more actively. That’s why a hungry person often hears his stomach “rumbling”.

Feeling hungry indicates our body needs nourishment that comes from variety of good quality of food. For instance, from vegetables, meats, eggs, and dairy products like milk and butter.

How long can we survive without food? That depends on the individual’s body condition. A very calm person can live longer without food than an excitable one because the protein stored up in his or her body is used less actively.
