Lower dietary diversity in the first year linked to atopic dermatitis

A study published in Pediatric Allergy and Immunology has found that lower dietary diversity during the first year of life is associated with an increased risk of atopic dermatitis (AD) later in life. Researchers from Kyung Hee University College of Medicine in Seoul, South Korea, analyzed data from over 267,000 infants born between 2009 and 2010 in the Korean National Health Insurance Service database.

The study categorized food diversity at 12 months into low, moderate, and high, and found that infants in the low- and moderate-diversity groups had a significantly higher risk of AD compared to those in the high-diversity group. However, there was no significant interaction by infant sex or maternal history of asthma or AD. The authors suggest that further randomized controlled trials are needed to confirm these findings and inform evidence-based public health recommendations regarding dietary diversity during infancy.
