There has been an increased attention to the role of nutrition in relation to concentration and learning abilities among schoolchildren. Some studies indicate a positive relation between seafood intake and cognitive performance; however, this effect is so far not confirmed in intervention studies with seafood among schoolchildren.


In a non-blinded intervention study we have investigated, whether intake of a schoolmeal or omega-3 capsules will influence cognitive function among pupils at lower secondary school. Four hundred and seventy eight pupils were randomly allocated into three intervention groups, in which one group was served lunch with fatty fish, one group was served similar lunch with meat/cheese (without fish) and one group was given omega-3 capsules three times a week over a period of 12 weeks. The study was carried out in January to June 2015. At the beginning and at the end of the study, the pupils conducted cognitive tests, and we collected blood-, urine- and hair samples. The pupils also answered a questionnaire on diet, physical activity, sleep and mental health.
