Onions and Eczema: Common Ingredient, Hidden Trigger for Some
Onions are in many everyday meals, which can make eczema associations hard to notice. Some people tolerate onions well, while others flare based on amount, preparation, and meal context.
Why Onions Can Be Difficult to Interpret
- They appear in sauces, spice blends, and restaurant meals
- Raw and cooked forms may feel different for some people
- Garlic-onion overlap can blur which allium is driving symptoms
How to Test
Remove onions for 2-3 weeks, then reintroduce one simple onion exposure and track symptoms for 24-48 hours. Test raw and cooked onion in separate trials to avoid mixed signals.
