Adherence to mediterranean diet decreases severity of psoriasis

Adherence to mediterranean diet decreases severity of psoriasis

Patients with severe psoriasis displayed low levels of adherence to the Mediterranean diet, according to a study published in the journal JAMA Dermatology.

Mediterranean diet is a type of traditional diet in Mediterranean countries, characterized especially by a high consumption of vegetables and olive oil and moderate consumption of protein.

Previous studies have suggested that sticking to a healthy diet, such as the Mediterranean diet(MD), may reduce the risk of long-term systemic inflammation.

Celine Phan and his associates conducted a study to assess the association between a score that reflects the adhesion to a Mediterranean diet (MEDI-LITE) and the onset and/or severity of psoriasis.

The cross-sectional observational study by investigators included the patients with psoriasis who were identified via a validated online self-completed questionnaire and then categorized by disease severity: severe psoriasis, nonsevere psoriasis, and psoriasis-free. Data on dietary intake (including alcohol) were gathered during the first 2 years of participation in the cohort to calculate a score reflecting adherence to MD from 0 (zero) for no adherence to 18 for maximum adherence.

Confounding factors such as age, sex, physical activity, body mass index, tobacco use, and a history of cardiovascular disease were also recorded.

The study found that there was an “inverse” association between adherence to a MD and the severity of psoriasis, which suggests patients with severe psoriasis adhered less strongly to the MD.

The authors suggest that provided the findings are confirmed, adherence to a Mediterranean diet should be integrated into the routine management of moderate to severe psoriasis.

Psoriasis is a common chronic inflammatory disease that affects 1% to 2% of the general population of all ages. Patients with psoriasis show a greater prevalence of obesity and metabolic syndrome, both of which confer a higher cardiovascular risk.
