Best Foods for Psoriasis

Fatty fish, extra-virgin olive oil, and beans or lentils are among the best foods for psoriasis because they fit a balanced eating pattern that may support general health and reduce inflammation. No individual food is proven to treat psoriasis, and dietary changes should complement—not replace—prescribed care. For related drink choices, see the best drinks for psoriasis.

What are 8 of the best foods for psoriasis?

The AI symptom analyzer can help you organize concerns to discuss with a clinician, but it cannot diagnose psoriasis or rule out an urgent problem. Seek medical care rather than relying on it if you have concerning symptoms.

These foods are practical choices, not a proven ranking. A 2025 systematic review of psoriasis and diet found that Mediterranean-style diets and several dietary components may be associated with better psoriasis outcomes, but noted a lack of high-quality evidence. There are no established psoriasis-specific serving targets for the individual foods below; use portions that suit your appetite, overall diet, and medical needs.

1. Fatty fish

Fatty fish such as salmon, sardines, and trout provide long-chain omega-3 fats, which can influence inflammatory signaling. That mechanism is relevant to psoriasis, but it does not establish that eating fish will improve an individual’s skin.

Use a usual portion of cooked fish as the protein in a meal, alongside vegetables and a whole grain. Evidence strength: A review of nutritional therapy for psoriasis discusses omega-3 fats as a dietary option, but evidence does not establish a specific fish portion or a predictable improvement in psoriasis. Food and fish-oil supplements are not interchangeable in research findings.

2. Extra-virgin olive oil

Extra-virgin olive oil supplies mostly unsaturated fat and plant compounds called polyphenols. It is a central ingredient in Mediterranean-style eating patterns, which are of interest because psoriasis involves inflammation and is often accompanied by cardiovascular risk factors.

Use a small amount in place of butter or another saturated fat when cooking, or add it to vegetables or beans. Evidence strength: A 2025 randomized clinical trial tested a dietitian-guided Mediterranean diet that included extra-virgin olive oil alongside stable topical therapy. Because the intervention involved the overall diet and counseling, it cannot isolate the effect of olive oil itself.

3. Beans and lentils

Beans and lentils provide fiber and plant protein. Some dietary fiber is used by gut microbes, but the possible connection between the gut, inflammation, and psoriasis is still being studied.

Add a serving of cooked beans or lentils to a soup, salad, or grain bowl, or use them in place of some meat in a meal. If canned options are convenient, choose lower-sodium varieties when available. Evidence strength: The psoriasis dietary review found that fiber may be associated with improved outcomes, but it does not prove that beans or lentils independently improve psoriasis.

4. Leafy greens and other vegetables

Leafy greens, broccoli, carrots, and other vegetables provide fiber and a range of nutrients and plant compounds. Those nutrients support normal body functions, although the presence of a nutrient in a food does not prove that the food will reduce psoriasis plaques.

Include a portion of vegetables with meals in the form you prefer, whether fresh, frozen, cooked, or raw. Variety is more useful than relying on one supposedly special vegetable. Evidence strength: Vegetables fit a Mediterranean-style pattern studied in psoriasis; direct evidence that a particular vegetable improves symptoms is lacking.

5. Fruit, including berries

Fruit provides fiber and plant compounds, including pigments found in berries and other colorful fruit. Some of these compounds have antioxidant activity, but that is a biological property—not proof of a psoriasis treatment effect.

Choose a usual portion of whole fruit as a snack or alongside a meal. Fresh, frozen, and canned fruit can all be useful choices; look for fruit packed without added sugar when possible. Evidence strength: Fruit is part of the broader dietary patterns studied in psoriasis, but there is no established psoriasis benefit for berries or any other individual fruit.

6. Whole grains

Oats, brown rice, and whole-grain breads provide fiber and can replace more refined grains in a balanced diet. Fiber supports digestive health, while its precise role in psoriasis symptoms remains uncertain.

Choose a portion of a whole grain when making a meal, such as oats for breakfast or brown rice with beans and vegetables. Evidence strength: Research on dietary fiber and broader eating patterns is suggestive, not proof that a particular grain treats psoriasis. If you have celiac disease, choose gluten-free grains appropriate for that diagnosis rather than avoiding all grains.

7. Walnuts and other nuts

Walnuts contain unsaturated fats, including a plant form of omega-3 called alpha-linolenic acid. Other nuts also provide unsaturated fats and can be useful substitutes for foods higher in saturated fat.

Add a small handful of unsalted nuts to a meal or have them as a snack if you tolerate them. Seeds can provide a similar practical option for someone who cannot eat nuts, although a person with allergies should choose foods that are safe for them. Evidence strength: Nuts fit a Mediterranean-style dietary pattern, but there is no strong evidence that walnuts alone improve psoriasis; their plant omega-3 is not the same as the long-chain omega-3 found in fish.

8. Plain yogurt with live cultures

Plain yogurt can provide protein and live cultures. Researchers are studying whether gut microbes influence psoriasis-related immune processes, but the presence of live cultures in a food does not guarantee a clinical benefit.

Use a usual serving of plain yogurt with fruit, or add it to a savory meal. Choose an unsweetened option if you want to limit added sugar; a suitable nondairy alternative may be preferable if you cannot tolerate dairy. Evidence strength: A review of gut microbiota and psoriasis describes research into probiotics and other microbiome-directed approaches, but it does not establish that ordinary yogurt treats psoriasis.

Which foods should you limit with psoriasis?

Foods high in added sugar or saturated fat: Consider having sweets, processed meats, and other foods high in these ingredients less often, while building meals around the foods above. This is a general healthy-eating approach; a single food does not reliably cause a psoriasis flare.

Salty packaged foods: Compare labels when convenient and choose lower-sodium options more often. The psoriasis dietary review recommends avoiding high salt intake, although this does not mean that removing salt will treat psoriasis.

Alcohol: Limit or avoid alcohol, and ask your prescribing clinician for individual advice if you take medication that can affect the liver, such as methotrexate.

Gluten and dairy: Do not assume you need to eliminate either food group solely because you have psoriasis. Gluten avoidance is important for people with celiac disease, but testing is more reliable while you are still eating gluten, so discuss testing with a clinician before cutting it out.

If you suspect a food affects your symptoms, keep a simple food and symptom record and discuss the pattern with a clinician or registered dietitian. Flares can have many causes, so a change after a meal does not necessarily identify a trigger.

Who should be careful, and when should you see a doctor?

People who are pregnant or breastfeeding, children, and anyone with food allergies, celiac disease, kidney disease, or another condition requiring a special diet should get individualized advice before making major changes. If weight management is appropriate, a clinician or registered dietitian can help plan it without an overly restrictive diet.

If you take psoriasis medicines, ask your prescribing clinician about alcohol, supplements, and any relevant dietary precautions. Do not stop or change prescribed treatment or folic acid on your own; supplements, including fish oil, can also interact with medicines.

Arrange a medical appointment for a new or worsening rash, or for persistent joint pain, swelling, or stiffness. Joint symptoms can need early assessment and should not be managed with diet alone.

Seek emergency care for widespread rapidly spreading redness or pustules, especially with fever or feeling very unwell, or for extensive skin peeling. These symptoms can signal a serious condition that needs prompt medical assessment.
