WHAT MAKES US HUNGRY?

When we need food, our body begins to crave for it. But how do we know that we are feeling ‘hungry’? How does our mind receive the message and make us feel ‘hungry’? Hunger has nothing to do with an empty stomach, it begins when certain nutritive materials are missing in the blood. When the blood vessels lack these materials, a message is sent to a part of the brain called the hunger center. This hunger center works like a brake on the stomach and intestine. As long as the blood has sufficient food, the hunger center  slows up the action of the stomach and intestine  more active. This is why a hungry person often hears his stomach rumbling.
