Supplements of the omega-3 fatty acid DHA (docosahexaenoic acid)may alter the function of the brain associated with working memory, according to results of a new study with healthy boys.
Scientists from the Unversity of Cincinnati showed for the first time using neuro-imaging that supplementation with DHA alters the functional activity in cortical attention networks in humans.
"The present findings add to an emerging body of evidence from preclinical and clinical imaging studies that suggest that dietary DHA intake is a robust modulator of functional cortical activity," wrote lead author Robert McNamara in the American Journal of Clinical Nutrition.
The study follows hot on the heels of, and vindicates, backing from the European Food Safety Authority (EFSA) for DHA related brain and eye health claims for infants.
EFSA's Panel on Dietetic Products, Nutrition and Allegries (NDA) said DHA levels of 100 mg per day were appropriate for 7-24 month-old infants along with 200 mg per day for pregnant and lactating women.
Another shorter chain, omega-3 fatty acid, ALA (alpha linolenic acid), was affirmed as important for the normal brain development of children up to the age of 18, but no levels were specified.
