Chewing is the first step in digestion. While you chew, salivary glands start producing saliva because they are trying to break down the "food" since your body doesn't know the difference between Chewing Gum and food. This also triggers your stomach to produce

more acid in preparation to break down the "food" and your stomach expands, giving more space for the "food". This makes you hungry because your body is ready for digestion.
