Two studies, one in Spain and another in the UK, found that polyunsaturated fatty acids such as DHA were linked to greater mental development in children. The UK study found that of 107 preterm babies, the group that received fatty acids in fortified formula or through breast milk exhibited significant cognitive advantages over the placebo group, particularly among the girls. The study completed in Spain studied 500 children who were breastfed for approximately 14 months. The levels of fatty acids in the mothers' colostrum were recorded and by the end of 14 months, the scientists found a positive correlation between fatty acids and cognitive development.
Formulas are often fortified with DHA and other polyunsaturated fatty acids due to previous evidence that they are necessary for brain development. Fatty acids naturally appear in breast milk. They are easy to add to your diet through the consumption of flax seeds, walnuts, soybeans, salmon and many other types of fish.
