Why are food allergies exploding in the modern world? In this episode, we explore the concept of "evolutionary mismatch"—the idea that our Stone Age bodies are struggling to cope with our sanitized, urban lifestyles.

We discuss the "Old Friends" hypothesis, which suggests that by scrubbing away dirt and germs, we’ve destroyed the diverse bacteria our immune systems need to learn tolerance. We also look at how climate change and rising CO2 levels are making allergens more potent, and why epigenetics might be rewriting your DNA to make you more vulnerable. Finally, we break down the latest prevention strategies, from restoring gut health with probiotics to the early introduction of allergenic foods.
