Question:
Why is it important to chew food?
Answer:
An adult human has about 32 teeth. Some of these are used for biting and tearing food, while others help grind it up. The more we chew the easier it is for the body to digest the food. As we chew, the mouth releases saliva that moistens the food so that it passes through the digestive system without scraping any of the organs.
