Psoriasis is a chronic skin condition that speeds up skin cell production, leading to thick, scaly patches. It often appears on the elbows, knees, scalp, and lower back, causing itching and discomfort. The immune system overreacts, triggering inflammation that makes the skin regenerate too quickly.
Though no cure exists, lifestyle changes, including diet, can help manage symptoms.
How Diet Affects Psoriasis
A diet focused on plant-based foods and low in saturated fats can help lessen the severity of psoriasis. Researchers from King’s College London discovered that individuals who consume more fruits, vegetables, whole grains, and low-fat dairy products tend to experience less severe symptoms. Their findings support the principles of the DASH diet, which emphasizes heart health through nutrient-rich foods.
On the other hand, diets high in red and processed meats, which are rich in saturated fats, are associated with more severe psoriasis symptoms. These fats contribute to increased inflammation, making flare-ups more pronounced. Reducing saturated fat intake may be beneficial in managing the condition.
The Role of Plant-Based Foods

Plant-based foods provide essential vitamins, minerals, and antioxidants that help reduce inflammation.
Whole grains also contribute to inflammation reduction. They are high in fiber, which aids digestion and supports gut health—an important factor in managing autoimmune disorders like psoriasis.
How Low-Fat Dairy Helps
Dairy is often debated in psoriasis management, but low-fat options may be beneficial. Full-fat dairy contains saturated fats that can trigger inflammation, while low-fat versions provide calcium and vitamin D without the drawbacks.
The Impact of Salt and Sugar
Excess salt and sugar in the diet can make psoriasis worse. High salt intake raises blood pressure, which can increase inflammation in the body. Meanwhile, too much sugar contributes to weight gain and insulin resistance, both of which are linked to more severe psoriasis symptoms.
Cutting back on processed foods, sodas, and sweets may lead to noticeable improvements.

Omega-3s and Inflammation
Found in foods like salmon, flaxseeds, and walnuts, these fatty acids are known for their strong anti-inflammatory effects. Individuals with psoriasis who incorporate more omega-3s into their diet often experience reduced redness and irritation. These beneficial fats help keep the skin hydrated and assist in regulating immune responses.
Engaging in regular physical activity, paired with a diet focused on whole foods, helps manage weight and boosts overall health.
Lifestyle Changes for Better Skin
While diet plays a vital role, managing stress is equally essential, as emotional stress can trigger psoriasis flare-ups.
Adequate sleep is another crucial factor. Lack of sleep can impair the immune system and worsen inflammation, exacerbating psoriasis symptoms. Developing a bedtime routine and reducing screen time before sleep can improve rest and overall well-being.
