1. What is Eczema and How Does Diet Affect It?
Eczema, also known as atopic dermatitis, is a chronic inflammatory skin condition characterized by itchy, dry, and inflamed skin. While the exact cause of eczema is unknown, it is believed to be a combination of genetic predisposition, immune system dysfunction, and environmental factors. Diet plays a significant role in managing eczema symptoms because certain foods can trigger inflammation and exacerbate flare-ups. Understanding the relationship between diet and eczema is essential for developing an effective management strategy.
1.1. The Gut-Skin Connection
The gut-skin axis highlights the interconnectedness of the gut microbiome and skin health. An imbalanced gut microbiome, known as dysbiosis, can lead to increased intestinal permeability, often referred to as “leaky gut.” This allows toxins and undigested food particles to enter the bloodstream, triggering an immune response that can manifest as skin inflammation, including eczema flare-ups.
1.2. Inflammatory Foods and Eczema
Certain foods are known to promote inflammation in the body, which can worsen eczema symptoms. These foods often contain high levels of processed sugars, unhealthy fats, and artificial additives, all of which can disrupt the gut microbiome and trigger an inflammatory response. Identifying and avoiding these inflammatory foods is a key step in managing eczema through diet.
1.3. Food Allergies and Sensitivities
Food allergies and sensitivities can also play a significant role in eczema flare-ups. While true food allergies involve an immediate immune response, food sensitivities can cause delayed reactions that are more difficult to identify. Common food allergens and sensitivities that may trigger eczema include dairy, gluten, soy, eggs, and nuts. Keeping a food diary and working with a healthcare professional can help you identify your specific triggers.
2. Common Food Triggers for Eczema
Identifying specific food triggers is crucial for managing eczema effectively. While individual reactions vary, some foods are more likely to cause flare-ups than others. Here’s a detailed look at common food triggers and why they may exacerbate eczema symptoms:
2.1. Dairy Products
Dairy products, including milk, cheese, and yogurt, are common eczema triggers for many individuals. Dairy contains lactose, a sugar that some people have difficulty digesting, leading to inflammation. Additionally, the proteins in cow’s milk, such as casein and whey, can trigger an immune response in sensitive individuals, worsening eczema symptoms.
According to a study published in the Journal of the American Academy of Dermatology, dairy consumption has been linked to increased eczema severity in children. The study found that children with eczema who eliminated dairy from their diet experienced a significant reduction in their symptoms.
2.2. Gluten
Gluten is a protein found in wheat, barley, and rye. For individuals with celiac disease or gluten sensitivity, consuming gluten can trigger an immune response that leads to inflammation and skin irritation. Even in the absence of celiac disease, some people with eczema may find that eliminating gluten from their diet helps to reduce flare-ups.
A 2017 survey published in the Journal of the American Nutrition Association found that many participants with eczema reported improvements in their symptoms after adopting a gluten-free diet. This suggests that gluten sensitivity may be more common in individuals with eczema than previously thought.
2.3. Sugar
Refined sugars and processed foods high in sugar can contribute to inflammation throughout the body, exacerbating eczema symptoms. Sugar can disrupt the gut microbiome, leading to an overgrowth of harmful bacteria and yeast, which further promotes inflammation. Additionally, rapid spikes in blood sugar levels can trigger an inflammatory response in the skin.
A study published in the American Journal of Clinical Nutrition found that high sugar intake was associated with increased levels of inflammatory markers in the blood. Reducing your intake of sugary foods and beverages can help to lower overall inflammation and improve eczema symptoms.
2.4. Processed Foods
Processed foods, including fast food, packaged snacks, and convenience meals, are often high in unhealthy fats, sugars, and artificial additives. These ingredients can contribute to inflammation and disrupt the gut microbiome, making eczema symptoms worse. Processed foods also tend to be low in essential nutrients that support skin health, such as vitamins, minerals, and antioxidants.
A research review featured in the Journal of the Academy of Nutrition and Dietetics highlighted the detrimental effects of processed foods on skin health, noting that their consumption is linked to increased inflammation and impaired barrier function in the skin.
2.5. Eggs
Eggs are a common allergen and can trigger eczema flare-ups in some individuals. The proteins in eggs, particularly egg white, can cause an immune response in sensitive people, leading to skin inflammation and itching. If you suspect that eggs may be contributing to your eczema, try eliminating them from your diet for a few weeks to see if your symptoms improve.
2.6. Nuts and Seeds
While nuts and seeds are generally considered healthy foods, they can be allergens for some people. Common nut allergens include peanuts, tree nuts (such as almonds, walnuts, and cashews), and seeds like sesame and sunflower seeds. Allergic reactions to nuts and seeds can manifest as skin rashes, itching, and eczema flare-ups.
2.7. Soy Products
Soy products, including soy milk, tofu, and soy sauce, can be problematic for some individuals with eczema. Soy contains compounds that can mimic estrogen in the body, potentially disrupting hormone balance and triggering inflammation. Additionally, soy is a common allergen, and allergic reactions to soy can worsen eczema symptoms.
2.8. Nightshade Vegetables
Nightshade vegetables, such as tomatoes, peppers, eggplant, and potatoes, contain alkaloids that can trigger inflammation in some people. While not everyone is sensitive to nightshades, some individuals with eczema may find that eliminating these vegetables from their diet helps to reduce flare-ups.
2.9. Citrus Fruits
Citrus fruits, such as oranges, lemons, and grapefruit, are high in citric acid, which can irritate the skin and worsen eczema symptoms in some individuals. Additionally, citrus fruits can trigger histamine release, which can contribute to itching and inflammation.
2.10. Shellfish
Shellfish, including shrimp, crab, and lobster, are common allergens and can trigger eczema flare-ups in sensitive individuals. Allergic reactions to shellfish can cause skin rashes, itching, and inflammation.
3. Dietary Strategies to Manage Eczema
While avoiding trigger foods is essential, incorporating certain dietary strategies can help to reduce inflammation, support gut health, and improve eczema symptoms. Here are some evidence-based dietary approaches to consider:
3.1. Anti-Inflammatory Diet
An anti-inflammatory diet focuses on consuming foods that reduce inflammation in the body and avoiding those that promote it. This approach emphasizes whole, unprocessed foods, such as fruits, vegetables, lean proteins, and healthy fats.
Key components of an anti-inflammatory diet include:
- Fruits and Vegetables: Rich in antioxidants, vitamins, and minerals that help to combat inflammation.
- Healthy Fats: Such as olive oil, avocados, and fatty fish, which contain omega-3 fatty acids that have anti-inflammatory properties.
- Lean Proteins: Including fish, poultry, beans, and lentils, which provide essential amino acids without contributing to inflammation.
- Whole Grains: Like quinoa, brown rice, and oats, which are high in fiber and help to support gut health.
3.2. Elimination Diet
An elimination diet involves removing potential food triggers from your diet for a period of time, typically 2-3 weeks, and then gradually reintroducing them one at a time to monitor for symptoms. This approach can help you identify specific foods that are contributing to your eczema flare-ups.
The steps involved in an elimination diet include:
- Elimination Phase: Remove common food allergens and sensitivities from your diet, such as dairy, gluten, soy, eggs, nuts, and processed foods.
- Maintenance Phase: During this period, focus on eating whole, unprocessed foods that are unlikely to trigger inflammation.
- Reintroduction Phase: Gradually reintroduce each eliminated food one at a time, monitoring for symptoms such as itching, redness, and inflammation.
It is essential to work with a registered dietitian or healthcare professional when following an elimination diet to ensure that you are meeting your nutritional needs.
3.3. Mediterranean Diet
The Mediterranean diet is based on the traditional eating patterns of people living in the Mediterranean region. It emphasizes whole foods, plant-based foods, and healthy fats, while limiting processed foods, red meat, and sugary beverages.
Key components of the Mediterranean diet include:
- Fruits and Vegetables: Consumed in abundance.
- Olive Oil: Used as the primary source of fat.
- Fish and Seafood: Eaten at least twice a week.
- Legumes and Nuts: Consumed regularly.

The Mediterranean diet is rich in antioxidants, omega-3 fatty acids, and other nutrients that help to reduce inflammation and support overall health.
3.4. Probiotic-Rich Foods
Probiotics are beneficial bacteria that help to maintain a healthy gut microbiome. Consuming probiotic-rich foods can help to improve gut health, reduce inflammation, and support the immune system.
Good sources of probiotics include:
- Yogurt: Choose plain, unsweetened yogurt with live and active cultures.
- Kefir: A fermented milk drink similar to yogurt.
- Sauerkraut: Fermented cabbage.
- Kimchi: A traditional Korean fermented dish.
- Miso: A fermented soybean paste.
3.5. Prebiotic-Rich Foods
Prebiotics are non-digestible fibers that feed the beneficial bacteria in the gut. Consuming prebiotic-rich foods can help to promote the growth of probiotics and improve gut health.
Good sources of prebiotics include:
- Garlic
- Onions
- Leeks
- Asparagus
- Bananas
- Oats
3.6. Vitamin D
Vitamin D plays a crucial role in immune function and skin health. Low vitamin D levels have been linked to increased eczema severity. You can increase your vitamin D levels through sun exposure, diet, and supplementation.
Good sources of vitamin D include:
- Fatty Fish: Such as salmon, tuna, and mackerel.
- Egg Yolks
- Fortified Foods: Such as milk, yogurt, and cereals.
