Fish is high in heart-healthy omega-3 fatty acids, nutrients, rich in protein and low in saturated fat. Fatty acids, or good fats, look after your heart, boost blood level function, and may reduce inflammation among others.

How to Buy High-Quality Seafood

Once you’ve decided on the type of seafood to buy, go to the best fish market in your locale for the freshest catch of the sea. If there’s none, frozen seafood is available at your grocery. Items marked “frozen fresh” maintain a superior quality, aquatic creatures are processed when picked from the water and then frozen maintaining freshness and grade.

  • Free from slime.
  • The meat should spring back when touched with fingers.
  • Scales should be intact and shiny.

Fish Fillets

Fresh-cut fillets have meats that are elastic, moistly appearance without any browning around edges. The flesh separates if they are set aside too long. Packaged fillets should have minimum liquid, liquid deteriorates flesh quickly.

Shellfish

The shells of clams, oysters, or mussels should be closed, if there is a gape tap it to show movement. Their shells should be moist, flesh is plump, and covered with liquor.

Crabs and Lobsters

Crabs and lobsters should show activity, the lobster’s tail should curl and not hang when picked. Cooked lobster or crab should show bright-red color without any foul odor.

Shrimp

You’ll see movement of live shrimp in the fish market, shells should not have any dark edges or black spots, except for tiger shrimps with black lines between shells.

Squid

The meat of the squid should be firm, eyes are clear and full, skin should be untorn with creamy color and brown spots.
