Our cognition has a great impact on our ability to assimilate education and put itinto practice during the school years. Studies have shown that the cognitive ability canimprove with an increased intake of omega-3 fatty acids among both infants, school childrenwith ADHD and elderly. This makes it interesting to examine whether the cognition also canbe improved among healthy children without any neuropsychiatric diagnosis.Objective:The aim of this systematic review is to investigate if there are evidence to support thatsupplementation with omega-3 fatty acids has beneficial effects on cognition in children.Search strategy:Searches were performed in the databases PubMed and Scopus with the keywords omega-3,cognition, child and learning.Selection criteria:Age six to twelve years old, RCT's, human studies, articles written in Swedish or English,children without neuropsychiatric conditions and children well-nourished.Data collection and analysis:A total of seven articles met the search criteria, of which five were critical reviewed. Thearticles were reviewed by the SBU audit template for RCT's. The strength of evidence wasevaluated using the GRADE system.Main results:According to the reviewed articles there are moderate evidence (+++) that omega-3supplementation affects the reading comprehension among children and low evidence thatomega-3 supplementation affects the reading ability among children.Conclusions:There are no significant evidence that supplementation with omega-3 fatty acids benefitsreading comprehension and reading ability among children during interventions between eightand 40 weeks.
