Intelligence is not influenced by omega 3 fatty acids but by the environment

Infant intelligence is more likely to be shaped by family environment than by the amount of omega 3 fatty acids, called DHA, fed in breast milk or fortified formula, according to new research funded by the Medical Research Council and the Food Standards Agency.

Omega 3 fatty acids, particularly docosahexaenoic acid (DHA), are found in high concentrations in the brain and accumulate during the spurt in brain growth that occurs between the last trimester of pregnancy and the first year of life. Studies in animals have shown that a lack of DHA during periods of rapid brain growth may lead to problems in brain development but trials of the effect of DHA-fortified formula on brain function in babies have produced conflicting results.

In this study, MRC scientists followed 241 children from birth until they reached four years of age to investigate the relationship between breastfeeding and the use of DHA–fortified formula in infancy and performance in tests ofintelligence and other aspects of brain function.

Dr Catharine Gale, from the MRC Epidemiology Resource Centre at the University of Southampton, who led the study said:

“This study helps to dispel some of the myths surrounding DHA. We do know that there are clear health benefits to breast feeding but DHA, which is naturally present in breast milk and added into some formulas, is not the secret ingredient that will turn your child into an Einstein.Children’s IQ bears no relation to the levels of DHA they receive as babies. Factors in the home, such as the mother’s intelligence and what mental stimulation children receive, were the most important influences on their IQ.”
