In this episode, Kari first explains the fascinating workings of the immune system, exploring how it adeptly defends against bacteria and viruses but how the same system can lead to food allergies. She proceeds to explore the complexities of food allergies, detailing their typical developmental patterns, underscoring the significance of preventative approaches like early exposure, and highlighting the potentially life-threatening nature of severe food allergies.
