Summary

This study looked at whether giving eggs every day to babies around 6 months old helps them grow and develop better. About 1,200 infants in Guatemala took part. Half got eggs plus standard nutrition advice, and the other half got only the advice. The researchers measured development, growth, and diet quality to see if eggs made a difference.
