Are there any known health risks to early introduction of solids to an infant's diet?

Abstract

Few studies support an association between early introduction of solid food and atopic conditions, obesity, or any other illness (strength of recommendation [SOR]: B, cohort studies with mixed results). Very weak evidence suggests an increased risk of atopic dermatitis. A single cohort study found an association between early gluten exposure and increased risk of celiac disease in high-risk infants, who carry the HLA-DR3 or DR4 allele (SOR: B, single cohort study).
