This week, Emily and Perry take on fluoride, a mineral with proven benefits for your teeth and an army of skeptical influencers ready to fight their municipal water supplies, (weakened) tooth and nail. What is fluoride? When did we start putting it into the water? Do we still need to? Is there any truth to the skeptics' concerns? And can we all agree that the best hope for our kids' IQs is Dolly Parton? Plus: the shady backroom dealings of flavored vapes, the specious reasoning behind vaccine "choice," and a padded bra scandal in the Tour de France Femmes (avec Zwift!).  Submit a question for our weekly mailbag at wellnessactually.fm.See omnystudio.com/listener for privacy information.
