Since 1974, our eating habits have changed dramatically and none more so than with fish. The amount of fish we eat and the type of fish we eat has changed so much.

Back in 1974, a typical household in the UK bought 44g of white fish. Didn’t matter whether it was fresh, chilled or frozen. Now, 40 years later it has dropped to 19g per household, however it does remain the most popular choice of fish.

Other types of seafood have seen a dramatic rise including salmon that rose by 550% and shellfish that rose fivefold.

There could be good reason in the decrease of white fish being eaten. Other fishes such as mackerel and salmon are high in omega-3. Omega-3 fats are excellent for your heart and therefore your health. There is also a rumour that these healthy fats will boost your mood as well.

If you are looking for the best place to find healthy fresh fish, it is best to find your local fishmonger. A quality fishmonger will display their fish in an attractive fashion and surround it with crushed ice to maintain the fish’s close-to-frozen temperature.

When looking for a whole fresh fish, look for shiny skin, clear eyes and taut flesh that springs back when you press it. Check that the tail is moist and flat while the gills should be cherry-red. If the gills are brown, do not buy.

Most people buy fish fillets or steaks. For white fish fillets ensure that they are translucent in appearance with a pinkish tint. Colours fish is different; the flesh should appear dense without any gaps between the layers.

You should ask your fishmonger to remove the pin bones that run crosswise to the backbone. Also if the fishmonger has packaged the fish in plastic, ensure that there is little to no liquid in the package.
