• Infants who have low amounts of DHA in their diet have reduced brain development and diminished visual acuity. • The increased intelligence and academic performance of breastfed compared with formula- fed infants has been attributed in part to the increased DHA content of human milk. • Cultures whose diet is high in omega 3 fatty acids (such as the Eskimos who eat a lot of fish) have a lower incidence of degenerative diseases of the central nervous system, such as multiple sclerosis. • Experimental animals whose diets are low in DHA have been found to have smaller brains and delayed central nervous system development. • Some children with poor school performance because of ADD, have been shown to have insufficient essential fatty acids in their diet. • International Society of the Study of Fatty Acids and Lipids recommends an intake of 220 milligrams of DHA per day for healthy adults
