A Review and Update: The Impact of Diet and Supplements on Atopic Dermatitis

Atopic dermatitis (AD) is a chronic inflammatory skin condition thought to be impacted by several risk factors, from genetics to lifestyle. Diet is a lifestyle factor that is of great interest for patients and providers. While there are several diet-related studies that have aimed to understand which dietary patterns and triggers are associated with AD, there exists some conflicting evidence that makes dietary recommendations and decisions difficult and can put patients at risk of inadequate nutrition. A review of dietary patterns and supplements revealed that the most consistent and beneficial dietary patterns associated with improvements in AD were supplementation with probiotics and n-3 polyunsaturated fatty acids and reductions in sodium intake. Data for other diets and supplements like antioxidants and various vitamins were more inconclusive, supporting the need for more high-quality dietary research. Dietary changes have the potential to positively impact the management of AD and should be made in conjunction with a provider to ensure nutritional needs are met.
