Squid

The word calamari comes from the Italian for "squid." In North America, it generally refers to a battered and deep-fried appetizer served in restaurants and bars, though some people use it interchangeably with the main ingredient, the squid. While many Mediterranean countries serve some variety of squid, it's also popular across Asia.

Though squid isn't rich in omega-3s, it is low in fat, which is one reason it can still have a place in a heart-healthy diet. Squid also supplies certain nutrients that protect your heart, help keep your blood pressure normal and help keep your cholesterol within a normal range, all of which are reasons the seafood is a good choice in terms of your heart.

Because the vitamin E in squid is more efficiently used by your body when you also get plenty of vitamin C, squeezing lemon juice over cooked squid is a beneficial way to eat the seafood.
