Psoriasis is a chronic autoimmune skin condition that causes red, scaly patches on the skin. While there is no cure, managing symptoms through diet is becoming an increasingly popular approach. Many patients report improvements in their condition when they avoid certain inflammatory foods and adopt a nutrient-rich diet.

Scientific studies suggest that psoriasis and diet are closely linked, as certain foods can trigger flare-ups while others help reduce inflammation. This article explores the relationship between psoriasis and diet, the foods to avoid, and the best dietary approaches for managing symptoms.

What Is the Relationship Between Psoriasis and Your Diet?

Psoriasis is an autoimmune disease, meaning the immune system mistakenly attacks healthy skin cells. This results in rapid skin cell turnover, leading to the formation of scaly plaques. While genetics and environmental factors play a role, diet is a critical factor that can influence the severity and frequency of flare-ups.

How Diet Affects Psoriasis

  • Inflammation: Certain foods can trigger inflammation, worsening psoriasis symptoms.

  • Gut Health: A healthy gut microbiome is essential for immune regulation. An imbalance in gut bacteria may exacerbate psoriasis.

  • Obesity and Metabolic Syndrome: Studies show that obesity can worsen psoriasis symptoms. A healthy diet can help manage weight and reduce systemic inflammation.

  • Nutrient Deficiencies: Vitamins like D, A, and E, along with omega-3 fatty acids, play a role in skin health and immune function.

How Do Foods Cause Inflammation?

Inflammation is the body's natural defense mechanism, but chronic inflammation can contribute to autoimmune diseases, including psoriasis. Certain foods trigger an inflammatory response, leading to flare-ups.

Common Inflammatory Triggers

  • Processed Foods: High in saturated fats, trans fats, and refined sugars, these foods promote systemic inflammation.

  • Gluten & Dairy: Some individuals with psoriasis have gluten sensitivity or lactose intolerance, which can worsen symptoms.

  • Nightshade Vegetables: Tomatoes, potatoes, eggplants, and peppers contain solanine, which may trigger psoriasis flare-ups in some people.

  • Alcohol & Sugar: These increase inflammatory markers and negatively impact gut health.

Foods to Avoid If You Have Psoriasis

To minimize psoriasis symptoms, it's essential to eliminate or reduce inflammatory foods from your diet. Below is a list of foods that psoriasis patients should avoid:

Food CategoryWhy It's Harmful for Psoriasis
Processed FoodsHigh in trans fats, refined sugars, and additives, which promote inflammation.
Red MeatContains arachidonic acid, which can trigger pro-inflammatory responses.
Dairy ProductsSome psoriasis patients experience flare-ups due to casein and lactose intolerance.
GlutenFound in wheat, barley, and rye, gluten can trigger an immune response in sensitive individuals.
NightshadesTomatoes, eggplants, peppers, and potatoes may worsen psoriasis symptoms due to solanine.
AlcoholWeakens the immune system, increases inflammation, and may interfere with psoriasis medications.
Sugary FoodsExcess sugar promotes insulin resistance, leading to inflammation and worsening symptoms.
Fried & Fast FoodsHigh in trans fats and unhealthy oils, which increase inflammatory cytokines.

Foods to Eat If You Have Psoriasis

While some foods worsen psoriasis, others have anti-inflammatory properties that may help reduce symptoms. A psoriasis-friendly diet should include:

Food CategoryBenefits for Psoriasis
Fatty Fish (Salmon, Mackerel, Sardines)High in omega-3 fatty acids, which reduce inflammation.
Leafy GreensRich in antioxidants and vitamins A, C, and E, promoting skin health.
Nuts & Seeds (Walnuts, Flaxseeds, Chia Seeds)Provide healthy fats that help reduce psoriasis-related inflammation.
TurmericContains curcumin, a powerful anti-inflammatory compound that may help with psoriasis symptoms.
BerriesHigh in antioxidants that protect against oxidative stress and inflammation.
Olive OilA healthy fat that contains polyphenols, which help fight inflammation.
Probiotic Foods (Yogurt, Kimchi, Sauerkraut, Kefir)Improve gut health, which plays a role in immune function.

Diet Plans and Psoriasis Symptoms

Various dietary approaches have been proposed to help manage psoriasis symptoms. Below are some of the most popular diets that have shown potential benefits:

Dr. Pagano Diet

Dr. John Pagano's psoriasis diet focuses on alkaline foods and avoids inflammatory triggers like red meat, dairy, and processed foods. Key principles include:

  • Eating fresh fruits and vegetables

  • Avoiding nightshades, gluten, and processed foods

  • Drinking plenty of water to aid in detoxification

Paleo Diet

The Paleo diet emphasizes whole, unprocessed foods while eliminating grains, dairy, and processed sugars. It includes:

  • Lean proteins (fish, chicken, turkey)

  • Healthy fats (avocados, nuts, olive oil)

  • Plenty of vegetables

  • No processed foods or refined sugars

Mediterranean Diet

A well-researched diet known for its anti-inflammatory properties, the Mediterranean diet focuses on:

  • Olive oil as the primary fat source

  • Fatty fish (rich in omega-3s)

  • Legumes, nuts, and whole grains

  • Minimal red meat and processed foods

Autoimmune Protocol Diet (AIP)

The AIP diet is an elimination diet that removes potential inflammatory foods and focuses on nutrient-dense options. Key elements include:

  • Eliminating grains, dairy, nightshades, and processed foods

  • Eating organ meats, bone broth, and fermented foods

  • Gradually reintroducing foods to identify triggers

Keto Diet

The ketogenic diet is a low-carb, high-fat diet that may help reduce inflammation. Potential benefits for psoriasis include:

  • Lower insulin levels, which may decrease inflammatory markers

  • High intake of healthy fats from avocados, nuts, and olive oil

  • Avoiding sugar and processed foods, which trigger flare-ups

Conclusion

Managing psoriasis through diet requires avoiding inflammatory foods and incorporating nutrient-rich, anti-inflammatory options. While no single diet works for everyone, eliminating processed foods, gluten, and dairy while adopting a Mediterranean, Paleo, or AIP diet can significantly improve symptoms.
