Psoriasis is a chronic autoimmune disease that affects the skin, causing red, scaly patches most commonly on the elbows, hands, lower back, knees, and scalp. It is an inflammatory condition driven by the immune system, leading many people to seek alternative therapies to manage symptoms alongside conventional treatments. According to Dr. Paul Yamauchi, a clinical assistant professor of dermatology at the UCLA David Geffen School of Medicine, dietary changes may help reduce inflammation and relieve symptoms for some people. While more research is needed, evidence suggests that specific diets can reduce the severity of psoriasis and improve overall health.

In this article, we’ll explore how diet plays a role in psoriasis, foods to avoid, beneficial foods to include, and Ayurvedic remedies for managing symptoms naturally.

Understanding the Role of Diet in Psoriasis

Psoriasis is associated with systemic inflammation, which affects not only the skin but also increases the risk of conditions such as cardiovascular disease, diabetes, and obesity. As a result, many experts recommend anti-inflammatory diets to help manage symptoms.

Research indicates that diets like the Mediterranean diet, which emphasize fresh fruits and vegetables, whole grains, healthy fats, and lean proteins, may reduce the progression of psoriasis. On the other hand, diets high in processed foods, sugar, and saturated fats can promote inflammation and potentially worsen psoriasis symptoms.

In addition to adopting an anti-inflammatory eating plan, some people with psoriasis may benefit from identifying specific food triggers and eliminating them from their diet. A food diary can help track symptoms and identify which foods might be exacerbating flare-ups.

Common Food Triggers for Psoriasis

Several foods are commonly reported to worsen psoriasis symptoms. These include:

  • Gluten – Found in wheat, barley, and rye, gluten can trigger symptoms in people with gluten sensitivity or celiac disease.
  • Dairy Products – High-fat dairy foods are associated with inflammation and may contribute to psoriasis flare-ups.
  • Red Meat – Especially fatty cuts, which are rich in saturated fats and can promote inflammation.
  • Sugar – Refined sugars and high-glycemic foods can trigger inflammatory responses.
  • Alcohol – Excessive alcohol consumption can dilate blood vessels and promote inflammation, worsening psoriasis symptoms.

Diets That May Help with Psoriasis

Several dietary approaches have been reported to reduce psoriasis symptoms. These include:

  1. Mediterranean Diet
    Rich in fruits, vegetables, nuts, olive oil, whole grains, and seafood, the Mediterranean diet is known for its anti-inflammatory benefits. Studies suggest that it may slow the progression of psoriasis and reduce the risk of comorbid conditions like heart disease and diabetes.

  2. Gluten-Free Diet
    This diet is particularly beneficial for people who have both psoriasis and a gluten sensitivity or celiac disease. Eliminating gluten may help reduce inflammation and improve symptoms.

  3. Low-Carbohydrate, High-Protein Diet
    Reducing refined carbohydrates and focusing on lean protein sources can help regulate blood sugar levels, which may reduce inflammation and prevent flare-ups.

  4. Vegetarian or Vegan Diet
    Plant-based diets are naturally anti-inflammatory and high in antioxidants, which can help reduce oxidative stress and improve skin health.

  5. Paleo Diet
    The paleo diet eliminates processed foods, dairy, and grains, focusing instead on whole foods such as fruits, vegetables, nuts, seeds, and lean meats. This diet may reduce systemic inflammation and improve symptoms for some people with psoriasis.

Beneficial Foods for Psoriasis

Certain foods are known to have anti-inflammatory and antioxidant properties that may help reduce psoriasis symptoms. Incorporate these foods into your diet for better skin and overall health:

1. Fatty Fish and Omega-3s

Fatty fish like salmon, mackerel, and sardines are rich in omega-3 fatty acids, which help reduce inflammation. Omega-3s also support heart health, an important consideration for people with psoriasis who are at higher risk for cardiovascular disease.

2. Fruits and Vegetables

Fruits and vegetables are loaded with antioxidants and vitamins that help combat inflammation. Carrots, sweet potatoes, spinach, kale, and berries are particularly beneficial due to their high content of vitamins A and C.

3. Whole Grains

Unlike refined grains, whole grains such as brown rice, quinoa, and oats are rich in fiber, which helps reduce inflammation and promotes gut health.

4. Turmeric

Turmeric contains curcumin, a powerful anti-inflammatory compound. Adding turmeric to your meals or taking it as a supplement may help reduce psoriasis symptoms.

5. Probiotics

Maintaining a healthy gut microbiome can help manage autoimmune conditions like psoriasis. Probiotic-rich foods such as yogurt, kefir, kimchi, and sauerkraut support gut health and may reduce inflammation.

Foods to Avoid

  1. Processed Foods – These are often high in sugar, refined carbs, and unhealthy fats, all of which can promote inflammation.
  2. Dairy Products – High-fat dairy, such as whole milk and cheese, may trigger flare-ups in some people.
  3. Red Meat – Limit consumption of fatty cuts of beef and pork, which can increase inflammation.
  4. Sugary Beverages – Soda, sweetened teas, and fruit juices are high in sugar and can worsen psoriasis symptoms.

Ayurvedic Approach to Managing Psoriasis

Ayurveda, an ancient system of natural healing from India, offers holistic approaches to managing psoriasis through diet, lifestyle changes, and herbal remedies. According to Ayurveda, psoriasis is caused by an imbalance in the body’s doshas—particularly Pitta and Kapha. Ayurvedic remedies aim to restore this balance.

Ayurvedic Diet Tips for Psoriasis

  1. Focus on Bitter and Astringent Foods – Include leafy greens, gourds, and herbs like turmeric and neem.
  2. Avoid Sour and Spicy Foods – These can aggravate Pitta dosha and worsen inflammation.
  3. Stay Hydrated – Drink warm water with lemon throughout the day to flush toxins.
  4. Include Ghee (Clarified Butter) – Ghee is believed to have anti-inflammatory and detoxifying properties.
  5. Herbal Remedies – Neem, turmeric, aloe vera, and triphala are commonly used in Ayurveda to reduce psoriasis symptoms.
