Dietary Patterns and their Impact on Atopic Dermatitis: A Comprehensive Review

Atopic dermatitis (AD) is a prevalent, chronic inflammatory skin disorder exacerbated by dietary factors, among other triggers. The disease involves complex interactions between genetic, environmental, and immunological factors, with the gut-skin axis illustrating how intestinal health impacts skin condition. This underscores the potential of dietary management in modifying AD outcomes.

This review synthesizes current knowledge on the impact of dietary factors on AD. It explores the link between food allergies and AD, examines the gut-skin axis, and reviews dietary recommendations for managing AD.

A comprehensive review was conducted, focusing on observational and clinical trials published in the last decade. The studies reviewed encompass the role of various foods, including the impact of allergens, dietary patterns, and specific nutrients on the pathophysiology and management of AD.

Dietary factors significantly influence AD symptoms, with food allergies playing a pivotal role. Gut health, particularly the balance of gut microbiota, also significantly affects AD pathogenesis. Personalized dietary recommendations are essential for effective management. The review highlights research gaps in the understanding of food's role in AD, emphasizing the need for further trials and personalized dietary guidance.
