The National Psoriasis Foundation’s (NPF) Medical Board recently released guidelines on the use of dietary interventions among patients with psoriatic diseases.

“There is a critical lack of evidence on the relationship between psoriatic diseases and diet,” the authors said. “This literature gap speaks to the need for evidence-based dietary recommendations that are accessible to clinicians and patients.”

The NPF’s recommendations were based on data from 55 studies that evaluated diet interventions among 4534 participants with psoriasis. The quality of the studies was assessed to determine the strength of the recommendations.

Among the recommendations:

  • Dietary weight reduction with a hypocaloric diet is strongly recommended for patients who are overweight or obese.
  • A gluten-free diet is recommended for patients who have tested positive for serologic markers of gluten sensitivity, however this recommendation is weak.
  • Vitamin D supplementation and dietary weight reduction with a hypocaloric diet is weakly recommended for patients with psoriatic arthritis (PsA) who are overweight or obese.

In addition, the guidelines include recommendations on the Mediterranean diet, fish oil, and other supplements, including Vitamin B12.

“Adults with psoriasis and/or PsA can supplement their standard medical therapies with dietary interventions to reduce disease severity,” the authors concluded. “These dietary recommendations from NPF Medical Board will help guide clinicians regarding the utility of dietary interventions in adults with psoriatic diseases.”
