Once a week.
Here the scientific capacities agree:
Fish is important for the brain and eyes.
“Both the American health authorities and British scientists agree on this point: The omega-3 fatty acids EPA and DHA, which are important for the long, good functioning of the brain and eyes, cannot be produced by the body itself and should therefore be ingested through food.
Other foods also contain these omega-3 fatty acids,
but fish is considered a major source of this, so the advice is to include it in your diet 1-2 times a week.
Saltwater fish in particular are considered good suppliers of these important substances, above all sardines, mackerel, herring, salmon and anchovies.
The sources are as unique as the substances that the body draws from them. Overfishing and pollution of the oceans are serious problems, as are farms that use drugs, dyes and other additives to give salmon an intense red colour, for example.
Although this is permitted under food law, watery and hard-to-digest farmed salmon is really not a pleasure. Anyone who has tasted salmon from specially certified breeding facilities or even a wild-caught salmon in direct comparison will make a clear judgment.
A good fishmonger can provide information, and organizations like followfish ensure there is no need to worry about the source of the fish. If you don’t live on the coast, it’s easy to lose sight of fish. That would be a shame!
