Psoriasis Patients Cite Cutting Alcohol, Taking Omega 3 as Best Ways to Improve Skin

24 May 2017 --- A US study into common dietary habits, interventions and perceptions among patients with psoriasis has found that reducing alcohol, gluten, nightshades, and adding omega 3, vegetables and oral vitamin D were the most commonly reported dietary interventions leading to improved skin.

The study was based on the results of a 61-question survey administered to the US National Psoriasis Foundation membership. The survey was completed by 1206 psoriasis patients and focused on dietary habits, modifications, skin responses and perceptions.

According to the study, “compared to age- and sex-matched controls, psoriasis patients consumed significantly less sugar, whole grain fiber, dairy, and calcium (p < 0.001), while consuming more fruits, vegetables, and legumes (p < 0.01).” 

Use of dietary modification for improved skin was reported by 86% percent of respondents. The percentage of patients reporting skin improvement was greatest after reducing alcohol (53.8%), gluten (53.4%), nightshades (52.1%), and after adding fish oil/omega-3 (44.6%), vegetables (42.5%) and oral vitamin D (41%).

The researchers also found that certain diets had a positive effect on skin condition. The highest percentage of patients reporting a favorable skin response adhered to the following diets: Pagano (72.2%), vegan (70%) and Paleolithic (68.9%). Improving overall health was a commonly cited motivation for attempting dietary changes (41.8%).

This national survey is among the first to report the dietary behaviors of patients with psoriasis. According to the researchers, the data collected during this study “may benefit patients and clinicians as they discuss the role of diet in managing both psoriasis and associated cardiometabolic comorbidities.”

The study was published in Dermatology and Therapy and is available online.
