Psoriasis, a chronic autoimmune skin condition affecting millions globally, presents ongoing management challenges. While conventional treatments like topical corticosteroids, phototherapy, and systemic medications provide relief, the role of diet, specifically psoriasis detox diets, in managing symptoms is an area of increasing interest and debate.
Understanding Psoriasis
Psoriasis arises from an overactive immune system, which accelerates skin cell growth. This rapid turnover leads to the formation of thick, red patches covered with silvery scales, accompanied by inflammation and discomfort. Though psoriasis is not contagious, it can significantly affect the quality of life.
Conventional treatments aim to alleviate symptoms and manage flare-ups. These include topical treatments, phototherapy, and, for severe cases, systemic medications.
The Allure of Detox Diets
Dietary detoxes and cleanses have gained traction, promising benefits like improved digestion, increased energy, and clearer skin. These regimens often involve restricting certain foods, consuming specific liquids, or using "detoxifying" agents to eliminate toxins.
While some individuals report improvements in psoriasis symptoms after dietary detoxes, scientific evidence supporting these claims remains limited. Psoriasis is a complex condition influenced by genetics, the immune system, and environmental factors, making it difficult to attribute improvements solely to dietary changes.

Exploring the Pagano Diet
In "Healing Psoriasis: The Natural Alternative," Dr. John O.A. Pagano proposed a nutritional approach to cure psoriasis from the inside out. The Pagano diet centers on the idea that individuals with psoriasis have "leaky gut syndrome," which can be healed with specific foods and nutrients. Stress management is also emphasized as a crucial element in reducing inflammation.
The Pagano diet includes:
- Avoiding "acid-forming" foods like most red meat and processed foods.
- Consuming an alkaline diet rich in specific fruits and vegetables.
- Drinking fresh fruit and vegetable juices and plenty of water.
- Eliminating nightshade vegetables (tomatoes, peppers, eggplant, and white potatoes).
- Limiting dairy (cow’s milk, yogurt, and cheese).
- Replacing coffee and alcohol with herbal tea.
Protein sources include wild-caught fish, up to four eggs a week, poultry, and lamb (the only acceptable red meat). Gluten-containing grains are prohibited, with limited brown rice allowed. Some fruits and vegetables, like citrus and strawberries, are also restricted. Added sugar and fried foods are to be avoided.
It's important to note that the Pagano diet differs from the pegan diet, which is more aligned with the paleo diet.
Evidence Behind the Pagano Diet
Notably, no peer-reviewed studies specifically examine Dr. Pagano’s diet. The plan is based on his personal experiences, interactions with patients, and testimonials. However, some aspects of the diet align with evidence-based recommendations.

Psoriasis, being an autoimmune disease, involves inflammation. Avoiding inflammatory foods is a common strategy to prevent symptom exacerbation. Doctors and dietitians often advise people with psoriasis to avoid added sugar, alcohol, dairy, gluten, refined carbohydrates, and saturated and trans fats, mirroring some of Dr. Pagano's recommendations.
However, some of Dr. Pagano’s restrictions, such as nightshade vegetables, shellfish, and coffee, are not universally considered harmful. These foods are even included in the Mediterranean diet, often cited as an anti-inflammatory diet beneficial for psoriasis.
The "alkaline diet" theory, which suggests altering the body's pH through diet, is also questioned by researchers, as the kidneys tightly regulate the body's acid-base balance.
Furthermore, "leaky gut syndrome," which Dr. Pagano links to psoriasis, lacks definitive diagnostic or treatment methods. While researchers recognize the potential connection between gut health and systemic inflammation, further research is needed.
Should You Follow the Pagano Diet?
While some recommendations align with general dietary advice for psoriasis, it's unclear if all the listed food triggers apply to everyone. Restricting the diet unnecessarily may negatively impact quality of life and increase the risk of malnutrition by cutting out nutritious foods without proven negative impacts.

Keeping a food diary to identify personal food triggers can be a helpful alternative. Some individuals may react to only a few items, while others may have different sensitivities. Even common triggers like gluten don't affect everyone.
Dietary Strategies for Psoriasis Management
The Importance of a Psoriasis Diet Plan
A well-structured psoriasis diet plan can ensure the inclusion of skin-friendly vitamins and minerals while avoiding potential trigger foods. The increasing number of psoriasis patients looking for natural solutions emphasizes the importance of nutrition in managing the condition.
Focus on Anti-Inflammatory Foods
Inflammation is a key factor in psoriasis. A diet rich in anti-inflammatory foods and low in inflammatory substances can be beneficial.
Include plenty of:
- Fruits
- Vegetables
- Nuts (almonds, walnuts)
- Seeds (sunflower, chia, pumpkin, flaxseed)
- Turmeric
- Ginger
- Olive Oil
- Omega-3 Rich Fish (tuna, mackerel, salmon, trout)
Avoid:
- Sugar (biscuits, cakes, sweets)
- High saturated and trans fats
- Fizzy drinks
- Junk food
- Caffeine
- Red meat
- Fried foods
- Processed foods
- Refined starch
- White pasta and flour
- Dairy (if sensitive)
- Gluten (if sensitive)
Incorporate Fruits and Vegetables
Fruits and vegetables are rich in vitamins, minerals, and antioxidants that reduce inflammation and improve overall health. A variety of colorful fruits and vegetables, such as leafy greens, berries, citrus fruits, and cruciferous vegetables, should be included. Aim for at least six portions of vegetables and two portions of fruit daily.
Choose Lean Proteins and Healthy Fats
Lean proteins such as chicken, turkey, fish, and plant-based options like beans, lentils, and tofu are preferable over red meats, which can be inflammatory. Healthy fats can be found in nuts, seeds, olive oil, avocado, and fatty fish like salmon.
Avoid Trigger Foods
Avoiding trigger foods is crucial. Processed foods, sugary snacks, and alcohol are common triggers for psoriasis. Opting for whole, unprocessed foods and limiting alcohol intake can improve skin health.
Stay Hydrated
Adequate hydration is essential. Drinking plenty of water helps flush toxins and keep skin hydrated. Herbal teas like chamomile or green tea can also provide anti-inflammatory benefits.
Include Whole Grains
Whole grains are packed with fiber, vitamins, and minerals, promoting optimal digestive health, which is beneficial for skin health.
