Question

What do they mean when people say that digestion starts in your mouth?

Answer 1

When you chew, it is a sort of digestion, and it starts the whole process.

Answer 2

The mouth is the beginning of the digestive tract. In fact, digestion starts here as soon as you take the first bite of a meal. Chewing breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use. Hope I’ve helped ;)
