Plant-Based Foods for Chronic Skin Diseases: A Focus on the Mediterranean Diet

Abstract

Purpose of review: In this narrative review, we provide an overview of how adherence to a Mediterranean dietary pattern can complement traditional treatment strategies for psoriasis, acne, and hidradenitis suppurativa. We emphasize the importance of an integrated approach, with dietary interventions as a key component of holistic patient care.

Recent findings: Psoriasis, acne, and hidradenitis suppurativa are immune-mediated chronic diseases marked by systemic inflammation, with genetic and environmental factors influencing their onset. The Mediterranean diet, rich in plant-based foods with antioxidant and anti-inflammatory properties-such as whole-grain cereals, extra-virgin olive oil, vegetables, legumes, fruits, and nuts-has been shown to reduce the clinical severity of these conditions. It also supports weight control and positively impacts metabolic and cardiovascular risk factors, which are closely linked to these diseases. Dietary education, particularly about the Mediterranean diet, plays a crucial role in the management of these skin diseases and serves as an important non-pharmacological treatment option that can influence patient prognosis. This review offers specific nutrition recommendations for prescribing the Mediterranean diet to patients with chronic inflammatory skin diseases.
