7 Best Foods for Eczema: What the Evidence Says

Salmon, plain yogurt, and oats are sensible foods to include in a balanced diet when you have eczema, but none is proven to treat it. Food choices can support overall nutrition without replacing a clinician’s recommended skin care or medication. For a related overview, see the best drinks for eczema.

7 foods to consider for eczema

The ai symptom analyzer can help you organize symptoms for a medical visit; it cannot diagnose eczema or a food allergy.

These seven foods are practical choices, not a ranking of proven eczema treatments. There is no established eczema-specific serving size for any of them. Choose amounts that fit your usual meals, and avoid any food you are allergic to.

1. Salmon

Salmon provides protein and omega-3 fats, which have roles in normal body function and inflammatory processes. That makes it a useful part of a balanced diet, but it does not mean a serving of salmon will calm an eczema flare.

Try a usual meal-sized serving of fully cooked salmon with vegetables and a grain. Fresh, frozen, and canned salmon are options; choose the form that fits your budget and preferences. People who are pregnant can ask their clinician about suitable fish choices and local fish advisories.

Evidence: The studies cited here do not establish that eating salmon improves eczema. Avoid salmon if you have a fish allergy; do not try it at home to test whether the allergy has resolved.

2. Plain yogurt

Plain yogurt supplies protein and other nutrients, and some varieties contain live bacterial cultures. Interest in these cultures comes partly from research into the relationship between gut microbes and eczema, although the effects of particular probiotic products cannot be assumed for all yogurt.

Have a serving with oats or fruit, or use plain yogurt in a savory dip. Check the label if live cultures matter to you. If you have a milk allergy, avoid dairy yogurt and discuss suitable alternatives with a clinician or dietitian.

Evidence: A 2024 review and meta-analysis of randomized trials in children with eczema reported lower severity scores in trials of probiotics, sometimes combined with prebiotics. The trials studied probiotic products, not ordinary yogurt; they do not establish which yogurt, if any, helps eczema or whether the findings apply to adults.

3. Oats

Oats provide fiber and can be an easy base for a balanced meal. Their soluble fiber can be used by gut microbes, but a plausible connection between the gut and skin is not proof that eating oats improves eczema.

Prepare a usual bowl of oatmeal and add foods you tolerate, such as berries or plain yogurt. Unsweetened oats also work in savory dishes. If you need to avoid gluten for a diagnosed condition, look for oats labeled gluten-free because oats can be contaminated during processing.

Evidence: The research cited here does not establish an eczema benefit from eating oats. Eating oats is also different from applying an oatmeal product to the skin; evidence about one should not automatically be applied to the other.

4. Beans

Beans provide fiber and plant protein. Fiber helps nourish gut microbes, but researchers are still studying how changes in diet and the microbiome relate to eczema symptoms.

Add a usual serving of cooked beans to a soup, rice dish, or salad. Canned beans can be convenient; rinsing them can reduce some of the sodium. If beans are unfamiliar to you, add a small amount to a meal and adjust based on digestive comfort.

Evidence: A 2024 review of diet, microbes, and skin conditions discusses possible gut–skin connections. It does not establish that eating beans specifically treats eczema or identify a bean serving that reduces symptoms.

5. Berries

Berries contribute fiber, vitamins, and plant compounds to the diet. These nutrients support general health, but their presence does not demonstrate that berries reduce eczema inflammation or prevent flares.

Add a serving of fresh or frozen berries to oatmeal, plain yogurt, or a meal you already enjoy. Unsweetened frozen berries can be a practical option when fresh fruit is expensive or unavailable. Choose varieties you like and tolerate rather than searching for a particular berry marketed for skin health.

Evidence: The studies cited here do not show that berries specifically improve eczema. If a food repeatedly causes a reaction, discuss it with a clinician instead of assuming that the reaction confirms an allergy.

6. Leafy greens

Leafy greens such as spinach and kale provide fiber and a range of nutrients. They can help make meals more varied, but no specific leafy green has been established as an eczema treatment by the research cited here.

Include a usual serving in a salad, soup, or cooked dish. Fresh and frozen greens can both be useful; cooking may make some greens easier to add to a meal. There is no known amount to eat for eczema symptom relief.

Evidence: The case for leafy greens is mainly their nutritional value, not direct evidence of an eczema benefit. If you take a medication such as warfarin, ask your clinician about keeping vitamin K intake consistent before making a large change in how much leafy green food you eat.

7. Walnuts

Walnuts provide unsaturated fats, including a plant form of omega-3 fat, along with protein and fiber. These nutrients can contribute to a balanced diet, but the presence of omega-3 fat does not establish that walnuts improve eczema.

Add a small handful to a meal or snack, or sprinkle chopped walnuts over oats if you tolerate them. Whole nuts are a choking hazard for young children; ask a pediatric clinician about an age-appropriate texture and introduction. Avoid walnuts if you have a tree nut allergy.

Evidence: The studies cited here do not establish that eating walnuts reduces eczema severity. They also do not provide an eczema-specific portion or justify taking a nut-based supplement for skin symptoms.

Which foods should you limit for eczema?

Limit or avoid a food when you have a confirmed allergy or when your clinician has given you a specific reason to do so. A food allergy can coexist with eczema, but eczema alone does not mean that a particular food is the cause. Do not reintroduce a food that has caused a serious reaction unless an allergy specialist has advised you how to do so safely.

Routine, broad avoidance of milk, eggs, wheat, nuts, or other foods is not a proven strategy for everyone with eczema. A 2022 systematic review and meta-analysis of dietary elimination found low-certainty evidence that elimination diets may slightly improve eczema in some people. Restrictive diets can also make adequate nutrition harder and may carry other risks, particularly for children.

Sugary foods and highly processed snacks can be occasional choices within an overall balanced diet, but the evidence cited here does not establish a universal eczema trigger among them. Rather than cutting out entire food groups, discuss a repeated suspected reaction with a clinician. A dietitian can help maintain adequate nutrition if a restriction is medically necessary.

Who should be careful, and when should you see a doctor?

Seek emergency help for trouble breathing, throat or tongue swelling, faintness, or other signs of a severe allergic reaction after eating. Use prescribed epinephrine immediately if available, and call emergency services; do not wait to see whether symptoms pass.

Seek urgent medical advice for eczema that becomes rapidly more painful or widespread, develops pus or clusters of painful blisters, or occurs with fever. Arrange a medical visit if eczema is persistent, disrupts sleep, or is not improving with the treatment plan. A clinician can check for complications and discuss appropriate care; eczema guideline highlights address treatments as well as dietary avoidance.

Parents and caregivers should consult a pediatric clinician before restricting a child’s diet or changing an infant’s feeding because of eczema. People who are pregnant, have a known food allergy, take medications, or are considering supplements should also discuss major dietary changes with a clinician or dietitian. Continue prescribed medication unless your clinician advises otherwise.
