Consuming Omega-3 Intake During Late Pregnancy Could Help With Cognitive Development in Babies
Women who consume omega-3 fatty acids during late pregnancy may help enhance the cognitive and motor development in their babies, researchers at the Universite Laval have indicated.

For the study, researchers Gina Muckle and Eric Dewailly first measured docosahexaenoic acid (DHA) concentration, a type of omega-3 fatty acid involved in the development of neurons and retinas, in the umbilical cord blood of 109 infants.

"DHA concentration in the umbilical cord is a good indicator of intra-uterine exposure to omega-3s during the last trimester of pregnancy, a crucial period for the development of retinal photoreceptors and neurons," explained Dr. Dewailly.

Following this, the researchers conducted tests on these infants at 6 and 11 months.

The results showed that the babies' visual acuity as well as their cognitive and motor development were closely linked to DHA concentration in the umbilical cord blood at the time of their birth.

However, there was very little relation between test results and DHA concentration in a mother's milk among infants who were breast-fed.

"These results highlight the crucial importance of prenatal exposure to omega-3s in a child's development," said Dr. Muckle.

Researchers observed that DHA concentration in the umbilical cord blood was in direct relation with the concentration found in a mother's blood, a reminder of the importance of a mother's diet in providing omega-3 fatty acids for the fetus.

They also noted that DHA concentration was higher in the fetus's blood than in the mother's.

"While developing its nervous system, a fetus needs great quantities of DHA. It can even transform other types of omega-3s into DHA in order to develop its brain," said Dr. Dewailly.

The researchers recommend that all pregnant women should be encouraged to get sufficient amounts of omega-3s.

"A diet rich in omega-3s during pregnancy can't be expected to solve everything, but our results show that such a diet has positive effects on a child's sensory, cognitive, and motor development. Benefits from eating fish with low contaminant levels and high omega-3 contents, such as trout, salmon, and sardines, far outweigh potential risks even during pregnancy," the researchers concluded.

The study is published in a recent edition of the Journal of Pediatrics.
