Episode description
Salt has such a rich history that it was once (and is perhaps still) a sign of wealth. In this latest installment of our series on flavor and taste, "Taste Buddies," Scientist-in-Residence Regina G. Barber goes on a salty flavor journey with scientist Julie Yu. Along the way, Julie explains salt's essential role in our daily lives and how it affects our perception of food.Follow Regina on Twitter @ScienceRegina. Email Short Wave at ShortWave@NPR.org.
