Introduction:
Introduction: Psoriasis is included in most frequent inflammatory illnesses of the skin. It is supposed that the correct lifestyle, including appropriate, rational diet is a helpful factor in the treatment of this disease.

Objective:
The objective of the study was evaluation of selected nutritional habits of patients with psoriasis.

Material and Methods:
The survey covered a group of 40 patients with psoriasis. Nutritional habits were assessed using a questionnaire containing items concerning the number and regularity of consumption of meals, the frequency of consumption of selected groups of food products, and the habit of snacking between meals.

Results:
The investigations showed that the patients most often consumed 3 meals daily. Dinner was most regularly consumed by both males and females, whereas supper – by males. The daily food rations were characterized by low consumption of coarse-grained groats and wholemeal bread, milk and dairy products, fish and leguminous dry seeds. A high frequency of consumption of pork and raw fruits and vegetables was observed. Patients most often used rape oil and olive oil (2-3 times a week). The majority of patients most often used butter for spreading on bread. The study also showed that alcohol, forbidden for these patients, was consumed by 100% of males and 85% of females.

Conclusions:
The findings obtained indicated that an inadequate selection of the assortment of products consumed by the patients in the study may result in the intensification of pathological changes among patients with psoriasis.
