Chewing is the process of breaking down food into smaller pieces using the teeth. This mechanical action helps to mix the food with saliva, which contains enzymes that begin the digestion process. Chewing is an essential part of eating, as it makes food easier to swallow and digest. The act of chewing involves various muscles in the jaw, including the masseter and temporalis. Proper chewing can enhance the enjoyment of food and improve nutrient absorption. Additionally, it can help prevent digestive issues by ensuring that food is adequately prepared for the stomach.
