Managing Psoriatic Arthritis With a Whole Food Plant-Based Diet: A Case Study

Area of Science:

• Rheumatology
• Clinical Nutrition
• Inflammatory Diseases

Background:

• Psoriatic arthritis is a chronic inflammatory condition.
• Current management often involves long-term medication.
• Dietary interventions are increasingly explored for managing inflammatory polyarthropathies.

Purpose of the Study:

• To report a case of psoriatic arthritis remission.
• To investigate the potential role of a whole food plant-based diet in managing psoriatic arthritis.
• To support further research into diet and lifestyle interventions for inflammatory polyarthropathies.

Main Methods:

• A case study approach was used.
• The patient adopted a whole food plant-based diet, excluding added salt, oil, and sugar.
• Disease activity and medication use were monitored over time.

Main Results:

• The patient achieved significant symptom improvement and discontinued methotrexate.
• Sustained remission of psoriatic arthritis symptoms was observed.
• Dietary changes preceded medication cessation and symptom remission.

Conclusions:

• A whole food plant-based diet may be a viable strategy for managing psoriatic arthritis.
• Dietary interventions can potentially lead to medication discontinuation in select patients.
• Further research is warranted to validate the efficacy of diet in inflammatory polyarthropathies.
