Episode notes
Evolutionary Perspective on Allergies
- IgE antibodies, responsible for allergies, likely evolved to combat venomous creatures and parasites.
- This overreactive system sometimes causes anaphylaxis, potentially fatal when upright due to blood pressure drop.
Allergies vs. Intolerances
- Allergies are distinct from sensitivities and intolerances, as they are immune responses.
- Conditions like lactose intolerance involve other biological mechanisms, not immune system reactions.
Rising Allergy Rates
- Allergy rates are genuinely rising, evident in increased ER visits for anaphylaxis.
- This isn't solely due to more testing; data shows increases throughout recent decades.
