The pH Factor


Tasting Tongue

UPDATE NOV 12, 2009
Tongue Map Urban Myth

Generations of schoolchildren have learned about the "tongue map" an illustration showing the regions of the tongue that are sensitive to particular tastes. This notion was widely accepted as true at the time the pH Factor was created, but it is now considered to be an urban myth. Current research shows that sensitivity to the basic tastes does not vary significantly in different regions of the tongue.
