The Element Iodine: Its Discovery, Health Benefits, and Why It’s in Salt

from Everything Everywhere Daily: History, Science, Geography, & More · host Gary Arndt

Iodine is far more important than you might think. It was discovered accidentally, yet it can be found almost everywhere. It’s something so small you only need a trace of it, yet without it, entire populations can suffer devastating health consequences.  It has been used as a medicine and a disinfectant, and is even a critical chemical in the production of many of the electronic devices that we use today. Learn more about iodine and why this element matters so much on this episode of Everything Everywhere Daily.
