Natural Dietary Treatments for Psoriatic Arthritis

Psoriatic arthritis (PsA) is a chronic inflammatory condition that affects the skin and joints. While traditional medical treatments are essential, many individuals seek natural dietary options to manage their symptoms. Here’s a closer look at some foods that can alleviate the symptoms of psoriatic arthritis.

1. Anti-Inflammatory Foods

Fatty Fish: Fatty fish such as salmon, mackerel, sardines, and tuna are rich in omega-3 fatty acids. These healthy fats have powerful anti-inflammatory properties that can help reduce joint pain and stiffness. Research has shown that omega-3s can decrease the production of inflammatory molecules and improve symptoms in people with inflammatory arthritis (Harvard Health & Arthritis Foundation).

Berries: Berries, including blueberries, strawberries, and raspberries, are packed with antioxidants and vitamins. They contain quercetin and rutin, which have been shown to have anti-inflammatory effects. Consuming berries regularly can help reduce inflammation and support overall health (National Psoriasis Foundation).

Leafy Greens: Leafy greens such as spinach, kale, and Swiss chard are rich in antioxidants and anti-inflammatory compounds. They contain vitamins A, C, and K, as well as folate and magnesium, which can help reduce inflammation and support joint health (Mayo Clinic).

2. Foods Rich in Antioxidants

Turmeric: Turmeric is a spice that contains curcumin, a compound with strong anti-inflammatory and antioxidant properties. Adding turmeric to your diet can help reduce inflammation and alleviate pain associated with psoriatic arthritis. Studies have shown that curcumin can inhibit inflammatory pathways and reduce the symptoms of arthritis (National Center for Complementary and Integrative Health).

Ginger: Ginger is another spice with potent anti-inflammatory effects. It contains gingerol, which can help reduce inflammation and pain. Incorporating fresh or powdered ginger into your meals can provide relief from the symptoms of psoriatic arthritis (Johns Hopkins Medicine).

3. Foods That Support Gut Health

Probiotic Foods: Probiotic-rich foods such as yogurt, kefir, sauerkraut, kimchi, and kombucha can help maintain a healthy gut microbiome. A balanced gut microbiome is essential for a properly functioning immune system and can help reduce inflammation. Research has shown that probiotics can improve symptoms in individuals with inflammatory conditions (Harvard Health).

High-Fiber Foods: High-fiber foods such as fruits, vegetables, legumes, and whole grains support gut health by promoting the growth of beneficial bacteria. Fiber can help reduce inflammation by feeding these beneficial bacteria, leading to a healthier immune response. Studies suggest that a high-fiber diet can decrease inflammation in the body (Arthritis Foundation).

4. Foods to Avoid

Processed Foods: Processed foods, including fast food, sugary snacks, and refined carbohydrates, can increase inflammation and worsen symptoms of psoriatic arthritis. These foods often contain unhealthy fats, sugars, and additives that can trigger inflammatory responses (Mayo Clinic).

Nightshade Vegetables: Nightshade vegetables, such as tomatoes, potatoes, eggplants, and peppers, contain solanine, which may exacerbate arthritis symptoms in some people. While not everyone with psoriatic arthritis is affected, it may be beneficial to avoid or limit these foods if they trigger symptoms (National Psoriasis Foundation).

5. Hydration and Anti-Inflammatory Drinks

Green Tea: Green tea is rich in polyphenols, which are antioxidants that can help reduce inflammation. Drinking green tea regularly has been associated with reduced arthritis symptoms and improved joint health. The anti-inflammatory properties of green tea can help alleviate the discomfort associated with psoriatic arthritis (Johns Hopkins Medicine).

Water: Staying hydrated is crucial for maintaining overall health and reducing inflammation. Drinking plenty of water helps flush out toxins and supports joint health. Dehydration can exacerbate arthritis symptoms, so it’s essential to drink adequate amounts of water throughout the day (Mayo Clinic).


Incorporating these natural dietary options into your routine can help manage the symptoms of psoriatic arthritis and improve your overall well-being. While these foods can offer significant benefits, they should complement traditional medical treatments. Always consult with healthcare professionals before making any major dietary changes to ensure they are safe and appropriate for your condition. By making informed dietary choices, individuals with psoriatic arthritis can find relief and enhance their quality of life.
