Eczema, also known as atopic dermatitis, is a chronic skin condition characterized by inflamed, itchy, and often painful patches of skin. While genetics and environmental factors play significant roles in triggering eczema, diet can also influence flare-ups. For individuals with eczema, certain foods are known to aggravate the condition by promoting inflammation or triggering allergic reactions. This article explores 10 common foods that can trigger or worsen eczema, providing insights into their effects and potential alternatives.
1. Dairy Products
Dairy is one of the most common dietary triggers for eczema. Many people with eczema have sensitivities or allergies to cow’s milk and other dairy products like cheese, yogurt, and butter. The proteins in milk—casein and whey—can prompt the immune system to react, leading to inflammation and eczema flare-ups. In addition, dairy can increase mucus production, which can irritate the skin and respiratory system.
Alternatives: Try plant-based milk like almond, soy, coconut, or oat milk. You can also explore dairy-free cheese and yogurt options, which are increasingly available in most supermarkets.
2. Eggs
Eggs are another top allergen that can trigger eczema, particularly in children. The protein in egg whites, in particular, can cause an immune response in some individuals, leading to symptoms such as itchiness, redness, and eczema patches. For some people, the body sees this protein as a threat, activating an inflammatory response that worsens eczema.
Alternatives: For baking, use substitutes like applesauce, mashed bananas, or flaxseed mixed with water. Many plant-based egg alternatives are now available for cooking and baking needs.
3. Soy Products
Soy is a common ingredient in many processed foods, and for individuals with soy allergies or sensitivities, it can be a major trigger for eczema. Products like tofu, soy sauce, and soy milk contain proteins that can cause allergic reactions and inflammation, making eczema symptoms worse.
Alternatives: Consider using other plant-based proteins such as beans, lentils, or quinoa. For soy sauce alternatives, coconut aminos or tamari (gluten-free soy sauce) may be less reactive for some individuals.
4. Gluten
Gluten, a protein found in wheat, barley, and rye, is a known trigger for many people with eczema, especially those who have celiac disease or a gluten intolerance. The immune system may react to gluten by increasing inflammation, which can exacerbate eczema symptoms. Even if you don’t have celiac disease, gluten can still aggravate eczema due to its inflammatory properties.
Alternatives: Opt for gluten-free grains such as rice, quinoa, millet, and buckwheat. There are also numerous gluten-free bread, pasta, and flour options available in stores.
5. Nuts
While nuts are rich in healthy fats, they are also a common allergen that can trigger eczema in some individuals. Peanuts, in particular, are notorious for causing allergic reactions, including skin inflammation. Tree nuts such as almonds, cashews, and walnuts may also provoke eczema flare-ups for sensitive individuals.
Alternatives: If you are allergic to nuts, seeds such as sunflower, chia, and flax can be good alternatives. Nut-free butters made from seeds, like sunflower seed butter, offer similar nutritional benefits.
6. Shellfish
Shellfish, such as shrimp, lobster, and crab, are well-known food allergens that can exacerbate eczema symptoms. The proteins in shellfish can trigger an immune response in some people, leading to inflammation, itching, and worsening of eczema. This is particularly relevant for individuals who are allergic to crustaceans or mollusks.
Alternatives: If you have a shellfish allergy, you can substitute shellfish with fish like salmon or plant-based protein sources such as beans, tofu, or tempeh.
7. Citrus Fruits
Citrus fruits such as oranges, lemons, limes, and grapefruits are acidic and can cause skin irritation, particularly in individuals with sensitive skin or eczema. The high acidity levels in these fruits can sometimes trigger an inflammatory response, making eczema symptoms worse. Additionally, certain compounds in citrus peels, such as limonene, can act as allergens.
Alternatives: Opt for non-citrus fruits that are less acidic, such as apples, bananas, pears, or berries. These fruits are also rich in vitamins and antioxidants without the inflammatory effects of citrus.
8. Tomatoes
Tomatoes are another acidic food that can irritate the skin and exacerbate eczema. While tomatoes are packed with nutrients like lycopene, their high acidity and histamine-releasing properties can cause itching, redness, and inflammation in some individuals with eczema.
Alternatives: For a less acidic option, try using pumpkin, carrots, or sweet potatoes in place of tomatoes in recipes. You can also opt for tomato substitutes like roasted red peppers or beets to add color and flavor to your dishes.
9. Spicy Foods
Spicy foods, including those containing hot peppers, chili powder, and curry, can increase inflammation and irritation in people with eczema. Capsaicin, the compound that gives peppers their heat, can aggravate skin conditions, leading to heightened itching and redness. Additionally, spicy foods can raise body temperature, which can trigger sweating—a known eczema irritant.
Alternatives: Opt for milder seasoning options like herbs, ginger, or turmeric, which have anti-inflammatory properties that may help rather than harm eczema-prone skin.
10. Processed and Sugary Foods
Highly processed foods, particularly those high in refined sugar, have been linked to increased inflammation in the body, which can exacerbate eczema symptoms. Sugary snacks, sodas, and baked goods cause blood sugar levels to spike, leading to an increase in inflammatory markers. In addition, processed foods often contain additives, preservatives, and unhealthy fats that can irritate the skin and cause eczema flare-ups.
Alternatives: Focus on whole, unprocessed foods like fruits, vegetables, whole grains, and lean proteins. Natural sweeteners like honey or maple syrup can be used in moderation as a healthier alternative to refined sugar.
Tips for Managing Eczema Through Diet
While food triggers can vary from person to person, managing your diet can play a key role in controlling eczema symptoms. Here are some tips to help you avoid eczema flare-ups related to food:
Keep a Food Diary: Tracking what you eat and any subsequent eczema symptoms can help you identify patterns and specific food triggers.
Consult a Dietitian or Allergist: If you suspect food allergies or intolerances are contributing to your eczema, a healthcare professional can help guide you in eliminating triggers while ensuring you maintain a balanced diet.
Test for Allergies: Allergy testing can reveal sensitivities to specific foods. An elimination diet, where certain foods are removed and then reintroduced, can help pinpoint the culprits behind eczema flare-ups.
Opt for Anti-Inflammatory Foods: Incorporating foods rich in omega-3 fatty acids (such as salmon, chia seeds, and flaxseeds), antioxidants (like berries and leafy greens), and probiotics (from yogurt or fermented foods) can help reduce inflammation and improve skin health.

Conclusion
Eczema is a complex condition influenced by multiple factors, including diet. By being mindful of food triggers such as dairy, gluten, and processed foods, you can better manage flare-ups and reduce the severity of your symptoms. Each individual’s reaction to certain foods may differ, so it’s essential to monitor your body’s response and consult with healthcare professionals when necessary. Making thoughtful dietary choices can lead to healthier skin and a better quality of life for those with eczema.
