Our family has always followed many of the strategies commonly recommended for managing eczema, thanks to my own history with it and a sibling who has dealt with severe eczema. My children and I have only had mild symptoms, although I can’t know whether that is related to our habits or simply our individual risk. Those same habits have shaped how I manage other conditions too, including migraines and the hormonal symptoms from endometriosis and PCOS.
As a dietitian, I naturally consider diet, and I’ve seen nutrition support so many other health conditions. But the research on food and eczema is confusing, and it can be especially hard to sort out true food triggers from normal symptom fluctuations, particularly in young children.
Foods can play a role for some people, but eczema usually isn’t caused by eating the “wrong” foods. Diet is one lever, not the whole picture.

Eczema Is More Than a Food Problem
The outer layer of your skin acts as a barrier, meant to keep moisture in and irritants out. With eczema, that barrier doesn’t work the way it should, leaving the skin more vulnerable.
A change in a gene called filaggrin, which helps maintain that barrier, is one of the strongest known risk factors for developing eczema and ongoing disease. However, eczema likely results from an interplay among genetics, the immune system, the skin barrier, and environmental factors that contribute to the redness, itching, and inflammation you experience.
Environmental factors can include things like dry air, temperature, hot water, air pollution, and substances containing certain chemicals or fragrances that can irritate the skin. For a smaller group of people, food allergy is part of the picture too, most often in children with more severe eczema.
Food is one factor to consider among several. A weakened barrier, a triggered immune system, genetics, and environmental exposures all play a role.
Evaluate food triggers, but they’re just one piece of the puzzle.
Eczema and Midlife Skin Changes
Declining estrogen can affect more than hot flashes and your mood. Estrogen receptors are also present in your skin cells, and as estrogen drops, it affects your skin’s hydration, collagen, and the compounds that help hold your skin barrier together. This shift is one reason skin can get drier and more easily irritated in midlife.
There isn’t strong evidence that menopause itself makes eczema worse, but the barrier changes that come with lower estrogen can make skin more reactive. About 7.7% of adults ages 18 to 74 have physician-diagnosed eczema, compared with 18.3% of children. So while it’s less common than in childhood, it’s far from rare, and you’re not alone if you’re still dealing with it.
Foods That May Trigger Eczema Flares
Rather than listing foods to avoid, this section explains how to tell whether a specific food is affecting you.
Food Allergy Is Not the Same as an Eczema Trigger
Food allergies can cause a range of immediate symptoms, including hives, swelling, vomiting, wheezing, or difficulty breathing. An eczema flare is different. When food does play a role, the flare may show up hours or even a day or two later, which makes the connection harder to identify.
Food allergies and eczema often occur together, particularly in children with moderate-to-severe eczema. However, researchers warn that eczema flares can be inaccurately attributed to foods. Eczema naturally fluctuates, so a flare that happens after eating a particular food does not necessarily mean the food caused it.
If you consistently notice symptoms after eating the same food, especially symptoms that occur soon after eating, talk with your healthcare provider or an allergist to determine the most appropriate next steps.
Why Allergy Tests Can Be Misleading
Food-allergy testing can identify sensitization, meaning your immune system has produced antibodies to a food. But sensitization does not always mean you will have an allergic reaction when you eat that food.
This is especially important for people with eczema because they can become sensitized to foods without actually being allergic to them. Broad testing done just because you have eczema, rather than testing based on your specific symptoms, can identify foods you are sensitized to but already tolerate, which can lead to unnecessary elimination.
Common foods involved in food allergies include milk, egg, wheat, soy, peanuts, and tree nuts, but there is no universal list of foods that people with eczema should avoid. If you regularly eat a food without symptoms, a positive allergy test alone is not a reason to remove it from your diet.
For suspected food allergies, testing is most useful when it is guided by your symptoms and medical history and interpreted by a qualified healthcare professional.
Should You Try an Elimination Diet for Eczema?
If you suspect a food is making your eczema worse, it can be tempting to cut it out and see what happens. But the research does not support broad elimination diets as a standard treatment for eczema. If you cut multiple foods at the same time without reintroduction, you may end up with a very limited diet.
A 2022 systematic review and meta-analysis looked at 10 randomized controlled trials involving 599 people with atopic dermatitis. Overall, 50% of people assigned to an elimination diet had a meaningful improvement in eczema severity compared with 41% of those who did not eliminate any foods. The authors concluded that elimination may provide a small improvement (about 9 percentage points) in eczema severity, but the evidence was low-certainty.
Another important limitation for adults is that most people in these trials were young children. The median age across the studies was just 1.5 years, so we can’t apply these results directly to adults with eczema.
What About the Risks?
Eliminating foods unnecessarily can make a diet too restrictive. Depending on how many foods are removed, this can make it harder to meet your nutritional needs and may increase food anxiety or reduce enjoyment and flexibility around eating.
I removed all forms of dairy from my diet for 18 months while I was breastfeeding our second son, who had CMPA (cow’s milk protein allergy). It made eating outside the home and preparing food so difficult, and I had to use my nutrition training to make sure I was getting enough protein, vitamins, and minerals.
Prolonged food restriction without ever reintroducing those foods can be difficult long term. For children, the risks can be higher because unnecessary restrictions can also affect growth and nutrient intake.
When Might Elimination Make Sense?
A short, structured elimination may be reasonable when you strongly suspect a specific food is contributing to your symptoms. Rather than removing several foods indefinitely, work with a healthcare professional to identify the suspected food, establish a clear baseline, remove it for a defined period (4 to 6 weeks), and then reintroduce it when appropriate and watch for symptoms.
The goal isn’t just to feel better while avoiding the food. It’s to find out whether the food consistently affects your eczema. If you notice other changes while the food is out, like better digestion or less bloating, write those down too. Reintroduction will show you whether those improvements are really tied to the food.
If you have symptoms that suggest a food allergy, like hives, swelling, vomiting, wheezing, or difficulty breathing after eating, talk with an allergist rather than starting an elimination and reintroduction on your own.

Instead of a list of foods to cut, this tracker helps you look for real patterns: what you ate, how you slept, your stress level, and what touched your skin, all next to how your skin actually looked that day.
A pattern across a few weeks tells you more than any single flare. It’s free to download, and you don’t need email.
What to Eat When You Have Eczema
Build a Supportive Diet Without Promising a Cure
A Mediterranean-style eating pattern is a reasonable, realistic foundation regardless of how much it helps your eczema. It has some of the strongest evidence of any dietary pattern for lowering inflammation markers, and it’s also been shown to support heart health and blood sugar. That’s why I recommend an anti-inflammatory eating style as a practical foundation for overall health, even when you’re not trying to treat a specific condition. I focus on what’s likely to help the most while still fitting into real life for most households.
This eating pattern emphasizes plenty of fruits and vegetables, beans and whole grains, nuts and seeds, fish, olive oil, and adequate protein, while generally limiting highly processed foods, added sugars, and processed meats. While it has not been established as an eczema treatment, it provides a practical structure for building a nutrient-dense, minimally restrictive diet that supports overall health.
You don’t need to find the perfect eczema diet. Build meals around protein, fiber-rich carbohydrates, healthy fats, and colorful plants. A Mediterranean-style pattern gives you a flexible framework without unnecessarily restricting foods you enjoy.
What About Salt?
Some research points to sodium intake. One large cross-sectional study of more than 215,000 adults found that higher estimated sodium intake was associated with higher odds of eczema, active eczema, and greater eczema severity. However, the study can’t tell us whether sodium contributes to eczema or is simply associated with it.
We also don’t have clinical trial results showing that reducing sodium improves eczema. For now, I wouldn’t treat sodium as a proven eczema trigger. Instead, this is another reason to eat more minimally processed foods commonly found on an anti-inflammatory diet.
What About Supplements?
Vitamin D Has the Most Encouraging Supplement Evidence
Vitamin D has the strongest research behind it: a 2024 systematic review and meta-analysis of 11 trials and 686 participants (children and adults) with eczema found that vitamin D supplementation modestly but significantly reduced eczema severity.
However, this research was in people with eczema, so this is a potential treatment, not a way to prevent eczema. A practical step is to get your vitamin D level checked and correct any deficiencies, while monitoring your skin and laboratory marker response, instead of adding a high-dose supplement on your own.
Probiotics and Other Supplements Are Less Certain
Probiotics may help too, but most of this research has been done in children, and studies often lump many different strains together, so no single product or dose can be recommended with confidence. An anti-inflammatory eating pattern is already rich in foods like vegetables, fruits, beans, and whole grains, which support overall gut health and help beneficial bacteria thrive.
Omega-3s, evening primrose oil, vitamin E, and zinc don’t have strong evidence for either treating or preventing eczema.
Other Factors That Can Affect Eczema
Here’s what else helps: for medical treatment, topical and prescription options and phototherapy are common; the National Eczema Association’s treatment guide is a good place to start.
Moisturizing and Protecting the Skin Barrier
Dermatology guidelines agree that moisturizing helps. The American Academy of Dermatology’s 2023 guideline for adults strongly recommends moisturizers, and they’re the only non-prescription option on that list with that level of confidence behind them.
Use a fragrance-free cream or ointment rather than a lotion, keep showers short and lukewarm, and apply moisturizer while your skin is still damp, within a few minutes of bathing, to lock in the water.
Fragrance, Sweat, Weather and Contact Triggers
I’ve noticed that when my children or I are exposed to scented soaps, laundry detergents, candles, or heavily fragranced fabrics, our skin can flare. This has happened at home, while traveling, and even after spending time in homes where these products are used regularly. For our family, avoiding fragrance, protecting the skin barrier, and keeping skin well moisturized have become part of our routine. Whenever we get away from those habits, our skin quickly reminds us how much they help.
Fragrance and certain preservatives are common irritants, and so are rough fabrics, fabric dyes, heat, sweat, and friction. Extreme hot or cold weather can further dry out or irritate skin, and so can smoke and air pollution. We often notice skin issues when traveling to a drier, winter climate from our warmer, more humid East Texas.
Some of these can also cause a true contact allergy on top of your eczema, especially fabric dyes, metals like nickel, certain preservatives, and fragrances. Not everyone needs to be tested, but persistent flares are worth asking about a patch test.
One thing not worth spending money on is a water softener. Hard water has a weak association with childhood eczema, but the two trials that tested installing one found no real difference in symptoms.
Stress, Sleep and the Itch-Scratch Cycle
Stress and poor sleep don’t cause eczema, but they can feed a cycle: stress and itching disrupt sleep, poor sleep makes itching harder to ignore, and scratching triggers more inflammation. In midlife, night sweats and hot flashes can add to this by interrupting sleep and adding sweat, which is another common irritant.
Researchers have looked at whether learning new habits can help (learning not to scratch). There isn’t much research yet on techniques for catching and replacing the urge to scratch. Group eczema education programs, where a nurse teaches skin care, treatment use, and itch management, can help some people.
Ask your dermatologist about how to manage your eczema and whether a class or nurse training visit is available. At night, keeping your nails short and moisturizing before bed can help.
Frequently Asked Questions
Should I Cut Out Dairy for Eczema?
Not unless you have a diagnosed milk allergy. A review of six trials with 288 people found no benefit from an egg-and-milk-free diet in people who weren’t selected for a food allergy. The only possible exception was infants with a suspected egg allergy and positive allergy tests, who may have improved on an egg-free diet. The trials were small and older, but newer research on elimination diets points the same way: any benefit is small and mostly seen in young children.
The idea that dairy is broadly “inflammatory” isn’t the same as a diagnosed allergy, and it isn’t a reason to cut it out. A Mediterranean-style pattern includes moderate amounts of dairy, especially yogurt and cheese. If lactose bothers your stomach, fermented options like yogurt and kefir are often easier to digest.
Should I Get Food-Allergy Testing?
Testing makes the most sense if you get immediate symptoms after eating, like hives or swelling, or if a baby’s eczema isn’t improving despite good skin care. Have an allergist interpret your results rather than acting on them alone; a positive result doesn’t always mean the food is a real problem for you.
Can an Anti-Inflammatory Diet Cure Eczema?
No. Eating well supports your overall health and might ease some symptoms, but no dietary pattern, anti-inflammatory or otherwise, has been shown to cure eczema. I recommend this eating pattern because of its proven benefits for inflammation, heart health, and blood sugar, whether or not it changes your skin.
How Long Should I Track a Possible Food Trigger?
One good or bad day isn’t a clear answer, since eczema fluctuates on its own. Track a few weeks on your usual diet first. Then, ideally with your provider’s input, remove one suspected food for 4 to 6 weeks and reintroduce it while watching for changes. The Eczema Food & Flare Tracker can help you spot real patterns.
Takeaways
- Eczema is mainly a skin-barrier and immune condition. Food can play a role for some people, most often when there’s a confirmed allergy.
- Broad elimination diets offer little benefit on average and can make eating harder than it needs to be. If you suspect a food, remove one at a time for 4 to 6 weeks, then reintroduce it, ideally with your provider’s help.
- A Mediterranean-style eating pattern is a practical foundation for overall health, even though it hasn’t been proven to treat eczema.
- Have your vitamin D checked and correct any deficiency. Other supplements have weaker evidence.
- Moisturize daily, avoid known irritants like fragrance, and look for patterns over weeks rather than reacting to a single flare.
Eczema can feel like a never-ending cycle of flares and guesswork, but small, steady habits with food, skin care, and tracking can help you find what works for you.
