Study Objective
To investigate the relationship between maternal nutrition during pregnancy and the development of cognitive functions in toddlers.
Short Abstract
This systematic review evaluates 17 studies focusing on maternal nutrition during pregnancy and its impact on cognitive functions in toddlers. The findings show that supplementation with iron, omega-3 fatty acids, folic acid, and vitamin D positively affects cognitive functions. However, iodine and zinc supplementation did not show significant effects. Diets including seafood during pregnancy were beneficial for cognitive development, reinforcing the importance of adequate maternal nutrition.
