Bell peppers

Nightshades

True allergy is uncommon. Mainly a concern for latex-allergic individuals due to protein cross-reactivity. For most people with eczema, bell peppers are low priority for elimination.

Summary

True bell pepper allergy is uncommon. Most reactions are either mild contact irritation or occur in people who are allergic to latex — bell pepper proteins can cross-react with latex proteins, causing immune reactions in that group. Bell peppers contain very little capsaicin (the compound that makes hot peppers spicy), so irritant reactions are minimal compared to chillies.

They are part of the nightshade family along with tomatoes, potatoes, and eggplant, but sensitivity to one nightshade does not automatically indicate sensitivity to all of them. Clinical evidence specifically linking bell peppers to eczema flares is limited. Unless specifically identified as a trigger through an elimination diary, bell peppers are generally low priority for removal.

The Details - Bell peppers & Eczema

Reaction Timeline

Immediate (minutes to 2 hours), Delayed (12–72 hours)

IgE reactions are immediate. Salicylate-driven or contact-irritant effects may be delayed. The delayed pattern is more commonly reported in AD communities.

How Much Is Needed To React?

Dose-dependent

A few slices in a salad are minimal exposure. A stuffed pepper or large serving of roasted peppers delivers more allergen. Red peppers are riper and may have different allergen profiles than green.

Does Preparation Matter?

Yes — preparation significantly changes reactivity

Cooking destroys heat-labile allergens (profilin). Roasting and charring may reduce some allergenic proteins. However, LTP allergens are heat-stable. Peeling (especially after roasting) removes skin-concentrated allergens. Raw bell pepper is more likely to cause reactions than well-cooked. [9]

Also Watch Out For...

Latex — cross-reactive allergens in latex-allergic individuals [9]
Other Solanaceae (tomato, potato, eggplant) — botanical family
Paprika — dried ground pepper, same species
Chili peppers — same Capsicum genus

What To Use Instead

Cucumber (for raw crunch in salads)
Zucchini (for stir-fries and cooked dishes)
Celery sticks (for dipping — note: celery is on the trigger list)
Jicama (for raw snacking)

Hidden Sources

Roasted red pepper dips and spreads
Fajita and stir-fry mixes
Jarred roasted peppers (in sandwiches, antipasto)
Paprika seasoning (dried ground pepper — see #29)
Pizza toppings
Pre-made salads and grain bowls

This content is for informational purposes only and is not medical advice. Food triggers are highly individual — a food appearing in this database does not mean it will cause your eczema to flare. The information presented is drawn from published clinical research and patient community reports, but it is not a substitute for professional diagnosis or treatment. If you suspect a food allergy or sensitivity, consult a dermatologist or allergist. The gold standard for identifying food triggers remains a supervised elimination diet with oral food challenges. Symphony is a tracking tool, not a diagnostic or medical device.
