because your stomach has no teeth

Many people have the habit of eating their food very quickly, which means that food does not get chewed sufficiently for proper digestion. First things first, you should chew your food because your stomach has no teeth! Digestion begins in the mouth: your saliva has enzymes that break down carbohydrates, and it lubricates the food which makes it easier to go down the esophagus. If you don't chew well enough, these steps are skipped, and the food particles remain too large for proper digestion. The larger food particles become a target for bacterial growth in your gut, leading to such fun things as indigestion and gas. Eating more slowly is an exercise in mindfulness, and it is essential when dieting, as you will be able to detect when you are full sooner.
