First seen Jun 25, 2026 · Last updated Sep 18, 2026 · Updated 3 times
Summary
This study followed 600 healthy infants from 2 months to 6 years old to see how being fed mostly breast milk, milk-based formula, or soy-based formula affects their growth, body composition, and brain function. Researchers measured physical development and neurobehavioral milestones. The goal is to better understand how early diet influences long-term health and development.
