Relationship between frequency of yogurt consumption at 1 year of age and development at 3 years of age: The Japan Environment and Children’s Study

Yogurt consumption habits at 1 year of age were associated with a lower risk of developmental delay at 3 years of age. However, the association was less apparent when yogurt was consumed more frequently. Possible mechanisms by which yogurt intake affects neurodevelopment include neurotransmitters produced by intestinal bacteria as well as the suppression of intestinal inflammation through improvements in the intestinal environment. Regular intake of yogurt in early childhood may have a positive association with neurodevelopment, but it is hoped that clearer links will be found in the future through intervention studies.
