Fish and the brain

Fish helps to better connect your brain cells, making you a cleverer and happier person.

A number of studies have shown that people who eat lots of seafood have fewer depressions, which is among the biggest single causes of absence due to illness and disability in Norway. Other studies show that dietary content rich in marine omega-3 fatty acids has a good effect on youngsters with learning difficulties. The reason is that the brain consists of a great deal of fat, much of which comprises the omega-3 fatty acids DHA and EPA.

  • Marine omega-3 fatty acids enable the brain cells to more easily connect with other brain cells. Given that all processes in your brain are electrical impulses, the number of contact points will have an influence on the mind.

  • Your brain cells are exposed to fewer damaging processes because the antioxidants in seafood ensure that the fat in the brain does not oxidise or turn rancid - processes that lead to fewer effective contact points.
