Eczema, also known as atopic dermatitis, is a chronic inflammatory skin condition characterized by itchy, dry, cracked, and inflamed skin. It affects a significant portion of the population, with up to 1 in 5 children and about 3 percent of adults experiencing this condition. While there's no definitive cure for eczema, many individuals seek ways to manage their symptoms through lifestyle changes, including dietary modifications. Among these, plant-based diets like vegetarianism and veganism have gained attention as potential strategies for alleviating eczema symptoms.
Understanding Eczema and Its Triggers
Eczema is often linked to allergies, suggesting an immune system connection. Food allergies, in particular, are suspected to exacerbate eczema symptoms in some individuals. Common food triggers include milk and dairy products, peanuts, eggs, soy, wheat, seafood, and shellfish. Identifying and avoiding these trigger foods can be an effective management strategy.
However, it's important to note that eczema triggers vary from person to person. What causes a flare-up for one individual might not have the same effect on another. Stress, environmental factors, and exposure to irritants can also contribute to eczema symptoms.
The Vegan Diet: A Closer Look
Vegans avoid all animal products, including meat, dairy, eggs, and products derived from animals and insects like gelatin and honey. Their diet consists primarily of plant-based foods such as fruits, vegetables, grains, legumes, nuts, and seeds.
A well-planned vegan diet can provide essential nutrients that may be beneficial for skin health, such as vitamins A, C, and E, zinc, and omega-3 fatty acids. These diets are typically rich in anti-inflammatory foods like fruits, vegetables, and nuts, which contain antioxidants that may help reduce inflammation in the body, potentially lowering skin irritation.

Potential Benefits of a Plant-Based Diet for Eczema
Several potential mechanisms could explain the reported benefits of plant-based diets for eczema:
- Reduced Exposure to Inflammatory Compounds: Cutting out meat and dairy naturally removes two major eczema triggers: arachidonic acid (from cholesterol-rich animal cell membranes) and saturated fats (linked to pro-inflammatory cytokines like TNF-α and IL-6).
- Increased Intake of Anti-Inflammatory Foods: Plant foods deliver powerful phytonutrients that guard your skin and gut against inflammation. Colorful berries, cruciferous veggies, turmeric, green tea, and flaxseeds are brimming with antioxidants, resistant starch, and anti-inflammatory compounds.
- Improved Gut Health: The high fiber content in a vegan diet supports a healthy gut microbiome, which plays a role in managing inflammation and skin conditions, including eczema. A balanced gut microbiome can promote healthy digestion and regular bowel movements.
- Elimination of Common Allergens: For some people, dairy products and eggs are associated with eczema symptoms. By eliminating these animal products from the diet, those with an allergy or sensitivity may see fewer flare-ups.
Considerations and Cautions
While a vegan diet can offer health benefits and potentially improve eczema symptoms for some, it's essential to approach it with mindfulness and caution.
- Nutrient Deficiencies: As with any diet, a poorly planned vegan diet can lead to nutrient deficiencies, including vitamin B12, iron, calcium, omega-3 fatty acids, and protein. It’s crucial to ensure you obtain the right amount of nutrients through food choices or, as necessary, through fortified foods and supplements.
- Hidden Triggers: Just because something is vegan doesn’t mean it’s healthy. You still need to read food labels, including nutrition facts and ingredients, and use your judgment to limit processed foods and avoid foods that don’t agree with your body.
- Individual Variability: Every person's body responds differently to dietary changes. What works for one individual with eczema may not work for another. Although a vegan diet eliminates some common allergens, such as shellfish, milk, and eggs, you may have sensitivities to certain plant-based foods like soy or nuts. Identifying and avoiding trigger foods is likely more effective at managing symptoms than blindly choosing a vegan diet.
Key Nutrients for Skin Health
Experts with the National Eczema Association suggest that instead of making a complete dietary change, people with eczema should focus on eating a diet rich in nutrients that support gut and immune health, including:
- Fiber
- Vitamins A, C, and D
- Zinc
Fiber and vitamin C are found primarily in plant-based foods. Vitamins A and D, along with zinc, are found in a mix of foods from both plants and animals.
The Importance of a Well-Planned Plant-Based Diet
A plant-based diet alone doesn’t denote a healthy diet. Choosing the right options might be a huge relief to your eczema condition. A plant-based diet is defined as all diets based on plant foods, including an abundance of vegetables, fruits, beans, lentils, legumes, nuts, seeds, fungi, and whole grains, with limited or no animal products or processed foods.

A whole food plant-based diet emphasizes whole foods that are minimally processed or refined and are free from artificial substances and additives. This type of diet can help with eczema because it avoids potential triggers of inflammation such as red meat, and emphasizes anti-inflammatory foods such as plant-based proteins, vegetables, fruits, nuts and seeds.
Refined carbohydrates and added sugar can easily elevate blood glucose levels, which in turn leads to increased production of pro-inflammatory chemicals. Consuming whole grains which are minimally processed and are high in fiber content can reduce the occurrence of inflammation. Moreover, processed foods are usually high in additives and food chemicals which could be triggering for eczema patients.
Practical Tips for Incorporating Plant-Based Foods
- Focus on Whole, Unprocessed Foods: Emphasize whole, unprocessed plant foods rich in polyphenols and omega-rich oils. Berries provide antioxidants, while flaxseeds and chia deliver anti-inflammatory omega-3s.
- Prioritize Anti-Inflammatory Ingredients: Incorporate spices like turmeric and ginger, which are known for their anti-inflammatory benefits.
- Consider Supplementation: Supplementation can be helpful, especially for nutrients that are harder to obtain in purely plant-based menus. Algae-derived EPA/DHA supports anti-inflammatory pathways, vitamin B12 prevents deficiency, and specific prebiotic fibers foster beneficial gut bacteria.
- Support Gut Health: Begin with a short course of targeted, clinically validated probiotics to reset dysbiosis, then maintain gut health by combining those strains with resistant starches (e.g., underripe bananas, cooked-and-cooled potatoes) and selective fibers (e.g., chicory root).
Recipes for Eczema Relief
- Comforting dishes full of healthful, anti-inflammatory ingredients to help soothe your skin during an eczema flare.
- Kelp Salad with Baked Tempeh and Kimchi Miso Dressing brings together highly nutritious fermented foods, including tempeh and kimchi, which support a healthy microbiome. This flavorful salad also has omega-3 fatty acids from the hemp seeds, calcium from the tahini, iodine from the kelp, iron from the beets, and zinc from the pumpkin seeds.
- Creamy Mushroom Soup with Chickpeas and Kale is a super cozy bowl of nourishing plants that provides comfort in more ways than one. In addition to the soup’s mouthwatering umami flavors from mushrooms, chickpeas, kale, and cashews, it packs a nutrient-dense punch! It’s a potent source of vitamin E, vitamin D (depending on the amount of sun exposure your mushrooms get), fiber, and protein, just to name a few.
The Mind-Gut-Immunity Connection
Eczema is, at its core, a gut-driven condition. An overgrowth of pathogenic bacteria and fungi can fan inflammatory flames, and unfortunately, a generic vegan diet often feeds them non-selectively with excess starches and sugars. A precise microbiome reset, followed by a diet tailored to nurture protective strains, can be beneficial.
The Role of Vitamin D and Probiotics
Vitamin D is essential for healthy bones and teeth and supports good immune function as it regulates the immune system (and atopic eczema is an autoimmune condition). Recent research suggests that vitamin D supplements may reduce the risk of babies developing atopic eczema.
Probiotics are live microorganisms (bacteria or fungi) that are consumed or applied to the skin to improve health. Studies have found up to 50% fewer cases of eczema in babies with a high risk of eczema (for example, if the mother has it) and where the itch-scratch cycle isn’t yet triggered, following probiotic treatment.
