Psoriasis is a multifaceted, chronic, inflammatory skin disease that impacts patients’ quality of life. The aim of this study was to investigate the relationship between the disease severity and quality of life of psoriasis patients and their nutritional status. The study included 40 patients in the psoriasis group, compared with 40 healthy individuals in the control group. A questionnaire for determination of socio-demographic characteristics and nutritional intake, anthropometric measurements, psoriasis area and severity index (PASI), and dermatology life quality index (DLQI) were used for the assessments. Daily food consumption details were recorded for three consecutive days to determine daily energy and nutrient intakes. Compared to the control group, the frequencies of single participants, primary school graduates, and housewives were higher in the psoriasis group (p < 0.05). The psoriasis patients weighed more and had an increased waist/hip ratio in comparison with the healthy individuals. The energy intake was lower in the psoriasis group (p < 0.01). There was not a significant statistical difference in the intake of proteins, fiber, vitamin A, vitamin E, vitamin C, Zn, Fe, and Mg supplements between the groups. However, there was an inverse correlation between the daily vitamin E intake and PASI scores (p < 0.05). There was a positive moderate correlation between the DLQI and PASI scores (p < 0.01). Our study indicated that lower daily vitamin E intake levels were associated with the severity of psoriasis. In addition to this, abdominal obesity seems to be another risk factor in psoriasis patients, even if they have a normal body mass index (BMI). An integrated healthcare approach with dermatologists, family physicians, and dietitians is essential to the management of psoriasis.
