Reexamining the Role of Diet in Dermatology.

Dermatologists often are asked by patients to provide dietary recommendations. It was previously thought that many skin conditions were unaffected by diet; however, increasing associations between specific nutritional practices and dermatologic conditions are being recognized. The role of diet in acne has been well studied, but rigorous studies on dietary interventions for other common skin conditions are lacking. Understanding the current nutritional strategies employed by patients as well as the existing literature behind these practices is crucial for dermatologists to provide recommendations for patients regarding diet and skin disease.
