For many families living with eczema, food becomes part of the story early on. Parents ask: "Are certain foods making my toddler's skin worse?" Adults wonder if cutting out milk, gluten, or eggs could calm their flare-ups. And online, you'll find endless advice—some helpful, some misleading—about what to eat and what to avoid.
The truth? Food and eczema have a complicated relationship. Food allergies can worsen symptoms for some people, but they are rarely the only cause. Instead, diet is one piece of a bigger puzzle that also includes genetics, environment, and even stress.
If you'd like to see how food fits into the larger eczema picture, start with our Causes & Triggers hub.
In this article, we'll explore:
- The most common foods that trigger eczema in toddlers
- The debate around dairy: does dairy make eczema worse?
- What an eczema elimination diet for adults might look like
- How food overlaps with genetics, environment, and emotional well-being
Food and Eczema: What's the Link?
Eczema isn't a food condition at its core—it's a skin barrier and immune system condition. But food can play a role in how severe flare-ups feel.
Here's what we know:
- Not everyone with eczema has food allergies.
- Cutting out foods without guidance can cause more harm than good.
- Children are more likely than adults to have food-triggered eczema.
Genetics can make this link stronger. For example, mutations in the FLG gene weaken the skin barrier, which may allow food allergens to provoke stronger immune reactions.
Foods That Trigger Eczema in Toddlers
Many parents notice flares soon after solid foods are introduced. But what are the most common foods that trigger eczema in toddlers?
Research points to a familiar group:
- Cow's milk (dairy)
- Eggs
- Peanuts and tree nuts
- Soy
- Wheat
- Fish and shellfish
Not every child will react to these foods. But together, they account for most food-related eczema reactions in toddlers.
That's why experts recommend talking to a healthcare provider before making big dietary changes for children.
Does Dairy Make Eczema Worse?
Few foods are debated as much as dairy. Parents ask, "Does dairy make eczema worse for my child?" Adults wonder if skipping milk will finally calm their skin.
The honest answer: it depends.
- In children with a confirmed cow's milk allergy, dairy often worsens eczema.
- In adults, lactose intolerance doesn't usually affect eczema—but milk proteins may still act as triggers for some.
- Cutting dairy without clear evidence of allergy rarely helps, and it can limit nutrients like calcium and vitamin D.
If you suspect dairy:
- Try a supervised elimination and reintroduction process with guidance from a healthcare provider.
- Explore alternatives like oat, soy, or almond milk—but remember, new sensitivities can happen.
Eczema Elimination Diet for Adults
Some adults experiment with an eczema elimination diet when other strategies haven't worked.
Here's how it usually goes:
- Remove possible triggers like dairy, gluten, eggs, soy, and nuts for several weeks.
- Track whether skin improves.
- Reintroduce foods slowly, one at a time, while observing flare patterns.
It can be helpful—but there are cautions:
- Too much restriction can make your diet unbalanced.
- Not all flare-ups are food-related; they may come from stress, climate, or irritants.
If you're curious about trying it:
- Work with a registered dietitian or healthcare provider.
- Keep a detailed food and skin journal.
- Focus on nourishing, whole foods during the process.

Food, Stress, and the Bigger Picture
It's easy to put food in the spotlight—but most flare-ups are multifactorial.
- Stress: Emotional stress is a major trigger. Learn more in Stress & eczema.
- Genetics: Family traits and barrier function make some people more reactive.
- Environment: Cold, dry air, pollution, and harsh cleansers often worsen skin independent of diet.
Practical Tips for Families and Adults
- Don't rush to restrict. Many toddlers outgrow food sensitivities, and overly strict diets can be stressful.
- Use food diaries. Write down meals and flare-ups to spot patterns over time.
- Seek professional guidance. Allergy testing and diet support prevent guesswork.
- Keep up with skincare. Moisturizers and gentle cleansers remain the foundation of eczema care.
- Remember the overlap. Food is one piece—environment and stress often play just as big a role.
While managing food triggers, don't forget the foundation: gentle, barrier-strengthening skincare. Strawberry's fragrance-free formulas help support compromised skin.
Conclusion
Food can influence eczema, but it's rarely the only cause. Foods that trigger eczema in toddlers—like milk, eggs, nuts, and soy—are important to recognize, but not every child reacts. For adults, questions like "Does dairy make eczema worse?" or whether to try an eczema elimination diet for adults should be explored carefully, ideally with professional support.
Eczema is always a combination of factors: diet, genetics, environment, and stress. Managing it means looking at the whole picture. For more, visit our Causes & Triggers hub, or dive deeper into Diet & elimination.
