Eczema is a skin condition that causes dry, itchy, and inflamed skin. Many people with eczema notice that certain foods can trigger flare-ups or make their symptoms worse. Understanding which foods to avoid can be an important step in managing eczema and keeping skin as healthy as possible.
In this article, we will explore the worst foods for eczema and why they can negatively impact your skin.
How Diet Affects Eczema
Eczema, also known as atopic dermatitis, is an inflammatory condition. Inflammation in the body can be influenced by many factors, including diet. Certain foods are known to promote inflammation, which can lead to a worsening of eczema symptoms.
While not everyone with eczema will have the same triggers, some foods are more likely to cause issues than others. The key is to identify which foods make your eczema worse and avoid or limit them.
Foods to Avoid with Eczema
The following are some of the worst foods for people with eczema. These foods are known to cause inflammation, trigger allergic reactions, or weaken the immune system, which can all contribute to eczema flare-ups.
1. Dairy Products
Dairy is one of the most common food triggers for eczema. Milk, cheese, butter, and yogurt contain proteins that some people with eczema may be sensitive to. Casein and whey, two proteins found in cow’s milk, can cause an immune response that leads to inflammation.

Why Dairy Is a Problem for Eczema
When your body reacts to dairy, it releases histamines, which cause itching, redness, and swelling. This reaction is especially common in people with food sensitivities or allergies to dairy. Even if you’re not allergic, dairy can worsen eczema by promoting inflammation in the skin.
Alternatives to Dairy
If dairy is a trigger for you, consider switching to plant-based milk alternatives such as almond, oat, or coconut milk. These can provide a similar taste and texture without the inflammatory effects of cow’s milk.
2. Gluten
Gluten is another common eczema trigger. Found in wheat, barley, and rye, gluten can be problematic for people with gluten sensitivity or celiac disease. Even for those without these conditions, gluten may contribute to inflammation and worsen eczema symptoms.
Why Gluten Can Make Eczema Worse
Gluten can irritate the gut and immune system in some individuals, leading to increased inflammation throughout the body. This inflammation can then show up on the skin as an eczema flare-up.
Gluten-Free Alternatives
If you suspect gluten is making your eczema worse, try replacing wheat products with gluten-free grains such as rice, quinoa, or gluten-free oats. Many grocery stores now carry gluten-free breads, pastas, and snacks.
3. Eggs
Eggs are another food that may trigger eczema flare-ups. They are a common allergen, especially in young children. The proteins in eggs, particularly in the egg whites, can provoke an immune response that leads to skin inflammation.
Why Eggs Can Be Problematic
Egg allergies or sensitivities are often linked to skin conditions like eczema. When your immune system reacts to eggs, it releases inflammatory chemicals that can cause itching, redness, and swelling.
Alternatives to Eggs
If eggs seem to trigger your eczema, try using egg substitutes in your cooking and baking. You can replace eggs with flaxseed meal, chia seeds, or commercial egg replacers.
4. Soy
Soy is another common food allergen that can trigger eczema in some people. Soy-based products like tofu, soy milk, and soy sauce contain proteins that may cause an immune response leading to skin irritation.
Why Soy Is a Problem
Soy allergies or sensitivities can cause the body to release inflammatory chemicals that lead to eczema symptoms. In addition, soy is often heavily processed, which can make it harder for some people to digest, further contributing to inflammation.
Soy-Free Alternatives
If you think soy is contributing to your eczema, you can try using alternative protein sources like beans, lentils, and chickpeas. Many plant-based products are now available that don’t contain soy.
5. Processed Foods
Processed foods, including fast food, chips, cookies, and sugary snacks, are loaded with unhealthy fats, refined sugars, and artificial additives. These ingredients can trigger inflammation in the body, which may worsen eczema symptoms.
Why Processed Foods Are Bad for Eczema
Processed foods contain trans fats, preservatives, and high levels of salt and sugar, all of which can promote inflammation. Additionally, these foods often lack the essential nutrients your body needs to repair and protect your skin.
Healthier Alternatives to Processed Foods
Instead of processed snacks, try eating whole, unprocessed foods like fresh fruits, vegetables, nuts, and seeds. These nutrient-rich foods can help support your skin health and reduce inflammation.
6. Sugary Foods and Drinks
Excess sugar can lead to a spike in inflammation, making eczema symptoms worse. Foods like candies, cakes, sodas, and other sugary treats can increase the levels of insulin in your body, which may promote inflammatory processes.
How Sugar Triggers Inflammation
When you eat too much sugar, your body releases insulin to help manage blood sugar levels. This increase in insulin can lead to the production of inflammatory chemicals, which can cause your eczema to flare up.
Cutting Back on Sugar
Reducing your intake of sugary foods and drinks can help minimize inflammation and support healthier skin. Try swapping sugary snacks for fresh fruit or nuts, and choose water or unsweetened tea instead of soda.
7. Nightshade Vegetables
Nightshade vegetables, including tomatoes, potatoes, peppers, and eggplants, can sometimes trigger eczema flare-ups in certain people. These vegetables contain a chemical called solanine, which some people with eczema find irritating.
Why Nightshades Can Be Problematic
While nightshades are healthy for most people, they can cause inflammation in individuals who are sensitive to solanine. This reaction can show up as increased itching, redness, and swelling on the skin.
Alternatives to Nightshades
If nightshades seem to trigger your eczema, try replacing them with other vegetables like carrots, sweet potatoes, and leafy greens, which are less likely to cause inflammation.
8. Shellfish
Shellfish, including shrimp, crab, and lobster, are common allergens that can trigger eczema in some people. Shellfish allergies can cause a severe immune response, leading to inflammation and worsening of eczema symptoms.
Why Shellfish Can Trigger Eczema
Shellfish contain proteins that can trigger an allergic reaction in some people. This reaction leads to the release of histamines, which cause itching and swelling, two common symptoms of eczema.
Avoiding Shellfish
If you are allergic or sensitive to shellfish, it’s best to avoid all types of shellfish, including shrimp, crab, and lobster. There are many alternative sources of protein, such as chicken, turkey, and plant-based options.
Keeping a Food Diary to Identify Triggers
Because everyone’s body reacts differently to certain foods, it can be helpful to keep a food diary. Writing down what you eat and how your skin reacts can help you pinpoint specific food triggers. Once you know which foods make your eczema worse, you can take steps to avoid them and reduce your risk of flare-ups.
Conclusion
While there is no one-size-fits-all approach to managing eczema, avoiding certain foods can help keep your skin healthy and reduce flare-ups. Dairy, gluten, eggs, soy, processed foods, sugar, nightshade vegetables, and shellfish are some of the most common culprits that can worsen eczema.
By eliminating or reducing these foods from your diet, and focusing on anti-inflammatory foods like fruits, vegetables, and healthy fats, you can better manage your eczema symptoms and improve your skin health. Always talk to a healthcare provider or a dermatologist before making significant changes to your diet, especially if you suspect food allergies.
Taking a proactive approach to your diet and identifying your triggers is key to managing eczema and living a more comfortable life.
