New dietary recommendations for adults with psoriatic arthritis

Adults with psoriasis and/or psoriatic arthritis can supplement their medical treatment with dietary interventions to reduce disease severity, says a large review of the evidence by the National Psoriasis Foundation in the US.

Experts looked at what dietary interventions help adults with psoriasis and/or psoriatic arthritis reduce their disease severity. They reviewed 55 studies involving 4,534 patients with psoriasis and/or psoriatic arthritis and found that:

• There was strong evidence for dietary weight reduction with a low calorie diet in overweight and obese people with psoriasis;
• The success of gluten-free diet and supplementation with vitamin D varies by subpopulations of adults with psoriatic diseases;
• Evidence is low when it comes to specific foods, nutrients, and dietary patterns in reducing psoriatic disease activity.

“We strongly recommend dietary weight reduction with a hypocaloric diet in overweight and obese patients with psoriasis,” the research group says. “We weakly recommend a gluten-free diet only in patients who test positive for serologic markers of gluten sensitivity. Based on low-quality data, select foods, nutrients, and dietary patterns may affect psoriasis. For patients with psoriatic arthritis, we weakly recommend vitamin D supplementation and dietary weight reduction with a hypocaloric diet in overweight and obese patients.”
