Ep 46 Lactose Intolerance: Never trust a fart

Ep 46 Lactose Intolerance: Never trust a fart

Everyone loves a good poop story, don’t they? We certainly hope so, because our good friend Katie shares a fantastic one to kick off our episode on lactose intolerance. In this episode, we explore what lactose is and the symptoms that lactose non-digesters experience when they eat some sneaky cheese or ice cream. Then we explain that this episode is actually flipped - turns out that not being able to digest lactose is the normal state, and those of us who can are actually the mutants! We trace the origins of this mutant allele and how the persistence of pastoralism spread milk drinking far and wide. Where do we stand with lactose intolerance today? Tune in for that answer and for an abundance of milk facts to arm yourself with for the next pub trivia night.
