Diet in Dermatology: Revisited

The document from 2010 reviewed the impact of diet on various skin conditions, including dermatitis herpetiformis, atopic dermatitis, acne vulgaris, psoriasis vulgaris, pemphigus, urticaria, pruritus, allergic contact dermatitis, and several genetic and metabolic disorders. It emphasized the necessity of a gluten-free diet for managing dermatitis herpetiformis and discussed the potential role of diet in exacerbating or alleviating symptoms of other conditions. Nutritional deficiencies and excesses were noted as causes for certain skin disorders. The review highlighted the controversial nature of dietary influences on atopic dermatitis and acne, with recent studies suggesting a possible link between diet and acne, particularly in non-westernized societies. It also mentioned that environmental factors, including diet, may influence psoriasis and that certain foods might trigger pemphigus in susceptible individuals. For urticaria, food was often suspected as a trigger, but type I allergic reactions were rarely the cause of chronic urticaria. The document underscored the lack of well-controlled trials to firmly establish the relationship between diet and these dermatological conditions and the importance of dermatologists being knowledgeable about dietary influences to provide comprehensive patient care.
