What’s really in your water, food, and air? In this eye-opening episode, Dr. Amy Shah sits down with her former mentor and world-renowned public health expert, Dr. Howard Hu, to unpack the hidden dangers in our environment that most people overlook.

With a storied career at Harvard, the University of Michigan, and now USC, Dr. Hu has spent decades at the forefront of environmental health research. Together, he and Dr. Shah explore hot-button topics like the link between fluoride and childhood IQ, how heavy metals like lead seep into our daily lives, and what the latest science really says about long Covid and multiple chemical sensitivity.
