What the research found
Scientists have uncovered a possible explanation for why some people struggle to taste food more than a year after recovering from COVID-19. By examining taste buds from patients with lingering symptoms, researchers discovered molecular abnormalities that weaken the signals responsible for detecting sweet, bitter, and savory flavors.
Evidence level: Human study. A study in people, but an association isn't proof of cause.
