Parents may want to encourage their kids to eat more fish and other seafood, as Science Daily reports that kids who lack Omega-3 fatty acids may have a harder time focusing in school.

Researchers from Oxford University took blood samples from 493 students from seven to nine years old and found that less than two percent of the participants' total blood fatty acids "were Omega-3 DHA (Docosahexaenoic acid) and only 0.5 percent were Omega-3 EPA (Eicosapentaenoic acid).” This amounts to a mere 2.45 percent, which falls below the recommended four percent needed for maintaining cardiovascular health and the optimal eight to 12 percent for keeping your heart at its peak.

Apart from its health benefits, Omega-3 fatty acids also affect children’s behaviour. “Higher levels of Omega-3 in the blood, and DHA in particular, were associated with better reading and memory, as well as with fewer behavior problems as rated by parents and teachers," study co-author Professor Paul Montgomery says.

Parents should train children to appreciate different kinds of food, instead of regularly serving unhealthy kiddie staples. Preparing food in fun and creative ways may help kids improve their academic performance.
