9. Mediterranean Diet
The Mediterranean diet is a well-researched eating pattern that emphasizes whole, minimally processed foods. It includes high amounts of vegetables, fruits, legumes, whole grains, nuts, and olive oil. Fish is consumed regularly, while red meat and dairy are limited. This diet is recognized for its anti-inflammatory and heart-protective effects.
For people with psoriatic arthritis, the Mediterranean diet offers several advantages. It supplies a rich variety of antioxidants, fiber, and healthy fats, all of which can reduce systemic inflammation. Olive oil, in particular, contains oleocanthal, a compound with properties similar to nonsteroidal anti-inflammatory drugs.
The diet’s emphasis on fish contributes a steady supply of omega-3 fatty acids, which as mentioned earlier, support joint health and reduce inflammation. Plant-based foods also support gut health by feeding beneficial gut bacteria, which in turn modulate immune function.
Clinical studies have shown that following the Mediterranean diet may reduce disease activity in people with rheumatoid and psoriatic arthritis. Some participants report less joint pain and better mobility after several months of consistent adherence.
In addition to reducing symptoms, this diet supports heart health, which is important because people with psoriatic arthritis have an elevated risk of cardiovascular disease. It may also help with weight management and blood sugar control, both of which can influence inflammation.
Adopting the Mediterranean diet is generally considered safe and sustainable. It is more of a lifestyle than a restrictive regimen, which makes long-term adherence easier. Many people find it enjoyable and flavorful, which improves the likelihood of continued success.
