Chewing gum may retrain your nose and tongue after smell loss

This study tested a new way to help people who have lost or distorted their sense of smell and taste. Instead of just smelling scents, participants chewed flavored gum to stimulate smell, taste, and feeling (like mint's coolness). 30 adults with smell or taste problems for 3 months to 2 years took part. Some chewed gum, some used standard smell strips, and some waited. The goal was to see if the gum approach is practical and helps improve flavor perception.
