Understanding Supertasting and Taste Sensitivity

The video explores the concept of supertasters, individuals with heightened taste sensitivity, particularly to bitter substances like PTC and PROP. Supertasting is a genetically inherited trait, and supertasters have more taste buds than average. The video explains how to test for supertasting using PTC strips or by counting papillae on the tongue. It also discusses the historical discovery of PTC sensitivity and its implications for taste perception. The video concludes with a call to action for viewers to support SciShow on Patreon.
