In the 1950s, apparently all kids in England got daily cod liver oil capsules at school.
Not sure when this stopped, but a recent article notes England is now considering giving every child a capsule of omega-3 oil before class.
Based on the overwhelming amount of research that’s been published over the last 5 years showing how beneficial omega-3 fats from fish oil are for your brain, I’d say this isn’t a bad idea. For reference you may want to read an earlier post I made about how fish oil improves learning and memory in children, as well as how omega 3 fish oil can improve focus and concentration.
