I love my fish, and as with most things in life also love variety. There is a lot of controversy about how healthy it is to eat these day because of the toxicity in some of the oceans. Which I find really heartbreaking. I think it's key not to become fearful of what we eat but just be well informed and wise about our choices.
Do you need to avoid the mercury found in fish?
For most people, the level of mercury absorbed by eating fish and shellfish is not a health concern. Overall, fish and shellfish are healthy foods. They contain high-quality protein and other essential nutrients, are low in saturated fat, and contain omega-3 fatty acids, a type of essential fatty acid. A balanced diet that includes fish and shellfish can contribute to heart health, brain health, bone health, reduce inflammation, protect against many diseases and aids children's growth and development.
Nearly all fish and shellfish contain traces of mercury. But some contain high levels. Eating large amounts of these fish and shellfish can result in high levels of mercury in the human body. In a fetus or young child, this can damage the brain and nerves (nervous system).
Because of the mercury found in fish, the U.S. Food and Drug Administration (FDA) and U.S. Environmental Protection Agency (EPA) advise the following people to avoid eating fish high in mercury and to eat limited amounts of fish and shellfish that are lower in mercury:
As far as sustainability for us in the UK goes, here is the latest...
“We’re suggesting that dab, hake, herring, mussels and mackerel become the new cod, haddock, salmon, prawns and tuna. By choosing from a wider range we’ll be putting far less stress on individual fisheries,” says Bernadette Clarke, MCS Good Fish Guide Programme Manager, who suggests a post-Brexit UK Top 10 which includes great tasting fish that aren’t a household name - yet.
The MCS, post Brexit, Best Choice Top 10
Dab, seine netted in the North Sea
Marine Stewardship Council (MSC) Certified hake from Cornwall
MSC certified herring from Irish, Celtic and North Seas, SW Ireland and Eastern English Channel
Mackerel, handlined in the southwest of England, and MINSA (Mackerel Industry Northern Sustainability Alliance) North East Atlantic MSC certified
Megrim from the Northern North Sea and West of Scotland
UK rope-grown mussels
Brown crab from Devon Inshore Potting Area, Western Channel
Queen scallops from the Fal Estuary, fished by traditional sail and oar method
Pollack handlined from the Celtic sea
I don't get farmed salmon but buy wild Keta salmon and smoked salmon from Alaska which I buy in M&S, where I also buy my prawns.
