Some people find that exposure to irritants and environmental factors can trigger periods of severe eczema symptoms. Eating certain foods can also trigger eczema flares.
This article discusses which foods might trigger an eczema flare and what to do if you suspect your diet is affecting your skin.
About eczema and food allergies

The rates of food allergies are high in people with eczema, but the exact correlation between the two conditions remains unclear. Food allergies and intolerance can cause itchy, flushed skin, in addition to stomach issues. But skin symptoms from food allergies and sensitivities are typically distinguishable from eczema symptoms.
A 2022 study notes that people sometimes incorrectly assume that certain foods cause their eczema symptoms, leading them to focus their treatment efforts on their diet rather than conventional options like moisturizers and prescription products.
The exact link between eczema and food allergies remains unclear. People with eczema may notice a correlation between symptoms and intake of certain foods, but this can vary on a person-by-person basis. People should speak with their doctor if they suspect certain foods are impacting their eczema symptoms.
Foods that may cause eczema
While everyone’s triggers can be different, common food allergies include:
- dairy
- eggs
- nuts
- soy
- gluten
- nightshade vegetables
People can use elimination diets to determine which foods may worsen their eczema symptoms.
Still, it is crucial to maintain a balanced, healthful diet to ensure adequate nutritional intake. Singular foods do not cause eczema and removing them from your diet is not a replacement for treatment.
Other allergens that may cause an eczema flare
In addition to food allergies, other allergies may cause eczema to flare up.
- perfume-containing products
- certain fabrics and detergent products
- environmental irritants like pollution, humidity, and temperature changes
- irritant chemicals
- dust mites
- pollen
- mold
- pets
Like with food triggers, the exact relation between these allergens and eczema flare-ups is not always well defined.
Discussing diet changes with a doctor
If you suspect that your diet is worsening your eczema symptoms, it’s a good idea to talk with your doctor.
They may recommend allergy testing, keeping a food diary, or talking with a registered dietitian to find out whether any allergens could be contributing to your eczema.
Your doctor can also recommend treatment beyond your diet. For example, the National Eczema Association lists these options:
- antihistamines
- pain relievers
- hydrocortisone gel or lotions
- medicated shampoos
- prescription steroid creams
- prescription injections
- prescription oral drugs
- phototherapy
