Eczema (atopic dermatitis) affects approximately 10–20% of children and 5–10% of adults in the UK, making it one of the most common chronic skin conditions. The relationship between eczema and diet is complex — for some people, specific foods trigger flares, while for others dietary triggers are minimal and the primary dietary influence is through systemic anti-inflammatory patterns rather than individual food avoidance. Understanding both dimensions allows for a more targeted and effective nutritional approach.
Food Triggers: Real for Some, Overstated for Others
Food triggers in eczema are highly individual. The most commonly implicated foods are dairy products, eggs, peanuts, tree nuts, wheat, soy, and fish — broadly overlapping with the major allergens. However, the evidence suggests that genuine IgE-mediated food allergy drives eczema flares in a minority of cases (primarily in young children with severe eczema), while the majority of adults with eczema do not have dietary triggers that significantly affect their skin.
The British Association of Dermatologists advises against blanket food elimination in eczema management and emphasises that unnecessary dietary restriction can lead to nutritional deficiencies without skin benefit. Identification of genuine food triggers should be done through a supervised elimination and reintroduction process with a registered dietitian, ideally with allergy testing where indicated. See the NHS guidance on atopic eczema for the current clinical approach.
Anti-Inflammatory Dietary Pattern
Independent of individual food triggers, the overall inflammatory tone of the diet significantly affects eczema severity. The Mediterranean dietary pattern — high in vegetables, fruits, whole grains, legumes, olive oil, and oily fish, with limited processed foods and refined sugars — reduces systemic inflammatory markers and is associated with lower eczema severity in observational studies. This dietary pattern is both health-promoting across all dimensions and specifically beneficial for inflammatory skin conditions.
Key dietary components with evidence in eczema: omega-3 fatty acids (from oily fish, walnuts, flaxseed) — anti-inflammatory effects on skin; probiotics (live yoghurt, kefir, fermented foods) — potential benefits particularly when started in pregnancy and early childhood; and vitamin D (from sunlight, oily fish, fortified foods, or supplements during winter) — deficiency is associated with worse eczema severity.
The Gut-Skin Axis in Eczema
The gut microbiome influences immune development and systemic inflammation — and this gut-skin connection is particularly relevant in atopic eczema, where immune dysregulation is a central mechanism. Studies have shown that children and adults with eczema tend to have less diverse gut microbiomes, with fewer of the bacterial species (particularly Lactobacillus and Bifidobacterium) that promote immune tolerance. Dietary strategies that support microbiome diversity — diverse plant foods, fermented foods, adequate fibre — may support eczema management through this gut-skin route. See our microbiome diversity guide.
Nutrients With Specific Evidence in Eczema
Evening primrose oil and borage oil — contain gamma-linolenic acid (GLA), an omega-6 fatty acid that may support skin barrier function. Evidence is mixed but some trials show modest benefit. Zinc — deficiency associated with impaired skin barrier and increased susceptibility to infection; adequate dietary zinc (pumpkin seeds, meat, legumes) supports skin repair. Vitamin E — protective antioxidant in skin lipids; found in sunflower seeds, almonds, and olive oil.
