Managing your diet is a crucial step in controlling flare-ups in atopic dermatitis and reducing the relentless itch associated with chronic skin inflammation.
Do you struggle with relentless itch every single day because of atopic dermatitis? You are not alone in this battle. Many people notice that their skin flares or becomes itchier after eating certain foods.
Now, the important question: does diet really affect atopic dermatitis?
How Are Diet and Atopic Dermatitis Linked?
Atopic dermatitis (AD) is a chronic inflammatory skin condition that causes itching, redness and dry, sensitive skin.
Although food does not directly cause atopic dermatitis, diet can significantly influence inflammation, immune responses, and the strength of the skin barrier. In some people with atopic dermatitis, these effects may worsen their symptoms. Meanwhile, for some who are lucky, the right food may help calm flare-ups.
Our gut and skin health are linked through the gut-skin axis. The gut contains trillions of bacteria that play a key role in digestion and immunity. When the balance of gut bacteria is disrupted, this leads to increased inflammation and an overactive immune response.
Foods To Avoid in Atopic Dermatitis
People with atopic dermatitis are more likely to have food allergies — especially in childhood — due to a phenomenon called ‘Atopic March‘ . Additionally, many adults find they have food sensitivities where certain ingredients do not cause a reaction but do make their skin itchier. As triggers may vary between individuals, these are the common culprits:
Common Food Allergens
Food allergies are more common in infants and children with atopic dermatitis. However, adults can be affected too.
Examples:
- Cow’s milk and dairy products (e.g. cheese, butter, cream)
- Eggs and egg-containing products (e.g. cakes, bread)
- Peanuts
- Tree nuts (e.g. walnuts, almonds)
- Soya products (e.g. soya milk, bean curd, tofu)
- Wheat and wheat-based products (e.g. bread, pasta)
- Shellfish (e.g. crab, shrimp, clam, lobster)
Important: The only way to clinically confirm a food allergy is through professional testing, such as a Skin Prick Test or Oral Food Challenge supervised by an allergist. Consult a healthcare professional before removing any major food groups to prevent nutritional deficiencies.
Highly Processed Foods
Ultra-processed foods may promote inflammation and worsen atopic dermatitis. Artificial additives such as food colourings and preservatives may also trigger itching or flare-ups in some people.
Examples:
- Foods high in refined sugars (e.g. sugary cereals, sweets, white bread)
- Fast food
- Packaged snacks
- Processed meats
Foods That May Help in Atopic Dermatitis
There is no single “eczema diet”, because triggers differ between individuals. Some foods are naturally beneficial for skin health and may curb inflammation. Because everyone’s triggers differ, focus on a skin-first nutrition plan: pack your plate with anti-inflammatory whole foods and—most importantly—steer clear of anything you are clinically allergic to.

Food Rich in Omega-3 Fatty Acids
Chronic inflammation plays a pivotal role in atopic dermatitis. Omega-3 fatty acids have anti-inflammatory properties. They may help support the skin barrier and calm flare-ups.
Bonus: Omega-3s are a double-win; while they strengthen your skin’s defences, they also support a healthy heart by reducing systemic inflammation and improving circulation.
Examples:
- Fatty fishes (e.g. salmon, sardine, mackerel)
- Flaxseed oil
- Walnuts
- Chia seeds
Fruits and Vegetables
Fruits and vegetables are rich in antioxidants, vitamins and phytonutrients that support skin repair and overall skin health.
Examples:
- Colourful vegetables (e.g. carrots, sweet potatoes, bell peppers, tomatoes)
- Leafy greens (e.g. spinach)
- Low-acid fruits (e.g. apples, pears, berries, red grapes)
- Green-tea
- Citrus fruits (e.g. oranges, lemons)
Note: While citrus fruits and tomatoes are high in Vitamin C, they are also histamine releasers. Some individuals with atopic dermatitis may find that these specific foods trigger an immediate itch or redness around the mouth. If you notice a flare after eating them, consider sticking to low-acid fruits like pears and blueberries.
Probiotic-Rich Foods
Probiotics are found in fermented foods. As gut health is closely linked to immune function, probiotics may help reduce symptom severity in some individuals.
When choosing yoghurt or kefir, look for products containing live and active cultures. Avoid versions with high added sugar, as sugar can feed bad gut bacteria and offset the benefits of the probiotics.
Examples:
- Unsweetened yoghurt with live cultures
- Kefir
- Fermented foods (e.g. miso soup, kimchi, tempeh, kombucha)
Note: While fermented foods are excellent for gut health, they are naturally high in histamines. For some people with atopic dermatitis, high-histamine foods can trigger an immediate itch flare. If you notice your skin reacts shortly after eating kimchi or miso, consult your doctor about histamine sensitivity.
Foods Rich in Vitamin A, C and E
Vitamins A, C and E are essential for skin health.
Functions and examples:
- Vitamin A supports skin maintenance and repair (e.g. carrots, sweet potatoes)
- Vitamin C aids collagen production and skin structure repair (e.g. citrus fruits, berries)
- Vitamin E has antioxidant and anti-inflammatory effects (e.g. avocados, green leafy vegetables)
Whole and Unprocessed Foods
Eating whole foods may reduce inflammation and support skin hydration by providing essential nutrients.
Examples:
- Whole grains (e.g. oats, brown rice)
- Legumes (e.g. lentils, chickpeas, and beans)
- Healthy Fats (e.g. raw seeds and cold-pressed oils like olive oil)
Food for Thought
Diet alone cannot cure atopic dermatitis, but right food choices may help reduce the symptoms. As triggers vary between people, keeping a food diary is important to identify food sensitivities.
Always consult a doctor or healthcare professional before completely eliminating any food triggers.
