The study involved 257 men and women with psoriasis, a frequently recurring inflammatory skin condition that causes redness, itching, and flaking. Currently, patients are most often prescribed hormonal ointments, but their limited effectiveness and the impossibility of regular use lead to recurrence of the skin lesions.
Scientists from King's College London decided to investigate how dietary habits impact symptoms in volunteers. In addition to dietary assessment, other important co-variates were analyzed, including gender, age, body mass index, medical history, smoking status, and alcohol consumption.
The worst results were seen in those who ate the least plant-based foods and frequently consumed red meat and processed meats. In contrast, the lowest psoriasis symptoms were seen in those who ate a diet rich in fruits, nuts, legumes, and other plant-based foods.
"Today, patients often ask what diet will help them cope with unpleasant, recurring symptoms. Our study provides some answers," said study co-author Tivi Maruthappu.
The scientists now plan to conduct a comparative study. If the results are similar, the findings will form the basis for new dietary recommendations.
Recently, Danish researchers introduced a patch for the treatment of psoriasis. It adheres to the skin, protecting it while slowly releasing medication.
