Episode notes
Food Allergy Rise
- Food allergy rates have doubled in recent decades, now affecting 1 in 13 U.S. children.
- This rise is unevenly distributed globally, with some regions experiencing no increase and varying allergens.
Allergic Reaction Mechanism
- During a food allergic reaction, the body mistakenly identifies a food protein as harmful.
- This triggers an immune response, releasing chemicals like histamine, which cause symptoms like itching and swelling.
Treating Allergic Reactions
- Mild food allergy reactions (e.g., itching, hives) can be treated with antihistamines.
- Severe reactions (e.g., vomiting, breathing difficulties, swelling) require epinephrine (adrenaline) injection.
