You may have heard our episode about our struggles with food labeling and Arlo's allergies. Well, so did Dr. Steve Proper, and he is an actual expert in the field! He teaches us about the medical science involved. What are allergies? What aren't they? How are they different from other seemingly similar phenomena?   But even more interestingly, a somewhat recent study completely changed our understanding of how food allergies are caused! Dr. Steve takes us through it.   Are you an expert in something and want to be on the show? Apply here! Please please pretty please support the show on patreon!
