Dietary behaviour in psoriatic patients.

Area of Science:

• Nutrition Science
• Dermatology
• Metabolic Health

Background:

• Psoriasis is a chronic inflammatory skin condition.
• Metabolic abnormalities are frequently observed in psoriatic patients.
• Dietary patterns are implicated in the pathogenesis and progression of various diseases.

Purpose of the Study:

• To investigate differences in dietary habits and alcohol consumption between psoriatic patients and non-psoriatic individuals.
• To explore potential links between specific food group consumption and psoriatic disease.
• To identify dietary factors that may contribute to metabolic abnormalities in psoriasis.

Main Methods:

• A semiquantitative, self-administered questionnaire was used to collect dietary data from 219 psoriatic patients and 747 non-psoriatic subjects.
• Food items were categorized into carbohydrates (CH), low-fat foods (LFF), high-fat foods (HFF), saturated fats (SF), and polyunsaturated fats (PUF).
• Alcohol and coffee intake were quantified, and age-adjusted comparisons were made using ANCOVA.

Main Results:

• Psoriatic patients exhibited higher consumption scores for high-fat foods (HFF) and saturated fats (SF) in males.
• Females with psoriasis showed increased intake of carbohydrates (CH), HFF, SF, and polyunsaturated fats (PUF).
• Both male and female psoriatic patients reported significantly higher daily alcohol consumption compared to controls.

Conclusions:

• Distinct dietary patterns, characterized by higher intake of fats and carbohydrates, are associated with psoriasis.
• Elevated alcohol consumption is prevalent in psoriatic patients.
• These observed dietary habits may contribute to the higher prevalence of metabolic abnormalities seen in individuals with psoriasis.
