Study Summary

This trial will study whether people with psoriasis are more likely to have food sensitivities, and if eliminating certain foods from the diet improves psoriasis symptoms.

Who is the study for?
This trial is for males and females aged 12 or older with chronic plaque psoriasis or guttate psoriasis covering at least 2% of their body. Participants should be in good health, able to follow the study plan, and have not used certain psoriasis treatments recently. Those with severe psoriasis, recent biologic treatment use, drug-induced or pustular psoriasis, pregnancy, lactation, diabetes mellitus, thyroid disease or inflammatory bowel disease cannot join.Check my eligibility
What is being tested?
The study is testing if a 12-week elimination diet can improve symptoms in people with psoriasis by removing foods they may be sensitive to. It aims to see if food sensitivities are more common in those with this skin condition compared to those without it.See study design
What are the potential side effects?
Potential side effects from the dietary changes could include nutritional deficiencies or reactions when reintroducing foods after elimination. However, specific side effects will depend on which foods are eliminated.
