Eczema, or atopic dermatitis, is a chronic inflammatory skin condition influenced by genetics, immune function, and environmental triggers. Diet isn’t a cure, and food alone won’t resolve a flare, but the Cleveland Clinic notes that some foods may help by supporting skin barrier function, reducing systemic inflammation, or providing nutrients like omega-3 fatty acids and zinc that play a role in skin health. For some people, certain foods are also triggers rather than helpers, which is a separate, individual issue worth tracking with a doctor or allergist if flares seem food-related.
Best Foods for Eczema Relief
1. Fatty Fish: An Omega-3 Source for Skin Barrier Support
Salmon, sardines, and mackerel are rich in omega-3 fatty acids, which have anti-inflammatory properties studied in relation to several inflammatory skin conditions, including eczema.
| Nutrient | Per 3 oz Salmon |
|---|---|
| Calories | 175 |
| Omega-3s | 1.8g |
| Vitamin D | 71% DV |
| Protein | 19g |
Best eaten: baked or grilled, 2 to 3 times a week.
2. Walnuts and Flaxseed: A Plant-Based Omega-3 Source
For anyone who doesn’t eat fish, walnuts and ground flaxseed supply ALA, a plant-based omega-3 the body partially converts to the same anti-inflammatory compounds found in fish.
| Nutrient | Per 1 Tbsp Ground Flaxseed |
|---|---|
| Calories | 37 |
| Omega-3 ALA | 1.6g |
| Fiber | 2g |
| Lignans | Very high |
Best eaten: ground rather than whole, since whole flaxseed passes through the digestive tract mostly undigested.
3. Sweet Potato and Carrots: A Beta Carotene and Skin Support Source
Beta carotene converts to vitamin A in the body, a nutrient involved in skin cell turnover and barrier maintenance.
| Nutrient | Per 1 Medium Sweet Potato |
|---|---|
| Calories | 103 |
| Vitamin A | 120% DV |
| Fiber | 4g |
| Vitamin C | 33% DV |
Best eaten: baked or roasted with the skin on.
4. Probiotic-Rich Foods: Studied for Gut-Skin Axis Support
Fermented foods like plain yogurt, kefir, and sauerkraut supply live cultures that support a diverse gut microbiome, a factor increasingly studied for its connection to skin inflammation through what researchers call the gut-skin axis.
| Nutrient | Per 1 Cup Plain Yogurt |
|---|---|
| Calories | 154 |
| Protein | 13g |
| Calcium | 30% DV |
| Live cultures | Present |
Best eaten: plain and unsweetened, since added sugar can offset some of the benefit for people managing inflammation.
5. Pumpkin Seeds: A Zinc-Rich Skin Support Food
Zinc is involved in skin barrier repair and immune regulation, and pumpkin seeds are one of the more concentrated plant sources.
| Nutrient | Per 1 oz |
|---|---|
| Calories | 151 |
| Zinc | 14% DV |
| Magnesium | 37% DV |
| Protein | 7g |
Best eaten: roasted as a snack, or sprinkled on salads and yogurt.
6. Berries: An Antioxidant Source for Inflammation Support
Berries carry a strong antioxidant load that may help offset some of the oxidative stress associated with chronic inflammatory skin conditions.
| Nutrient | Per 1 Cup Blueberries |
|---|---|
| Calories | 84 |
| Vitamin C | 24% DV |
| Fiber | 3.6g |
| Anthocyanins | High |
Best eaten: fresh or frozen, added to breakfast or eaten as a snack.
7. Olive Oil: An Anti-Inflammatory Fat
Extra virgin olive oil contains oleocanthal, a compound with anti-inflammatory properties, and it’s a foundational fat in the Mediterranean diet pattern often recommended for people managing inflammatory conditions.
| Nutrient | Per 1 Tbsp |
|---|---|
| Calories | 119 |
| Monounsaturated fat | 10g |
| Vitamin E | 10% DV |
Best eaten: drizzled over vegetables and salads, or used in place of butter for cooking.
8. Water-Rich Foods: Supporting Skin Hydration From the Inside
Skin hydration starts with overall fluid balance, and water-rich fruits and vegetables like cucumber and watermelon contribute to that alongside plain water.
| Nutrient | Per 1 Cup Cucumber |
|---|---|
| Calories | 16 |
| Water content | 96% |
| Vitamin K | 8% DV |
Best eaten: fresh in salads, or infused into drinking water.

| Probiotic foods | 1 cup yogurt | Live cultures |
| Pumpkin seeds | 1 oz | Zinc |

5 Additional Tips for Managing Eczema Through Diet
- Keep a symptom and food diary if you suspect certain foods worsen flares. Common suspected triggers include dairy, eggs, and gluten, though these are individual, not universal.
- Don’t eliminate major food groups without guidance from a doctor or allergist, especially for children, since unnecessary restriction can create nutritional gaps.
- Moisturize consistently. No food replaces a good topical skincare routine for eczema management.
- Limit added sugar and highly processed foods, which are linked to higher systemic inflammation in general population research.
- Work with a dermatologist for a full treatment plan. Diet is a supportive piece, not a standalone treatment for eczema.
The Bottom Line
No food cures eczema, but an anti-inflammatory, omega-3 and zinc-rich diet may support skin barrier function and help manage the condition alongside medical treatment. These 8 foods are a reasonable starting point for building that kind of eating pattern.
