What's in seafood?
One of the major benefits of eating seafood is that it’s packed with vitamins, minerals and other nutrients that keep our bodies in good working order.
Vitamins and minerals
Seafood is a great source of particular vitamins and minerals which hold very important functions within the body. Oily fish is a rich source of vitamins A and D, which are important in the growth and development of children. White fish is a good source of B vitamins, and all seafood is an excellent source of minerals including potassium, selenium, zinc and iodine. Iodine is needed for our thyroid glands and brains, while zinc keeps us in good reproductive health, and selenium is believed can actually help to protect us from cancer.
Seafood is an excellent source of protein, and also contains small amounts of 'good' fats. Protein-rich fish and shellfish can help to nourish your muscles, as well as warding off colds and flu. Foods with high protein contents tend to be low in calories while keeping us fuller for longer.
Salt and sodium
Despite being so high in minerals, seafood is very low in salt and sodium. Most of us eat too much sodium, which has been linked to high blood pressure, strokes and heart disease. Swapping a ready meal that's high in sodium for a seafood dish can help you to lower your salt intake and boost your health.
Shellfish and dietary cholesterol
It's also worth bearing in mind that shellfish contains dietary cholesterol. However, saturated fats (which seafood is low in) are much more responsible in causing high blood cholesterol levels than dietary cholesterol, which needn't be avoided unless you suffer from a genetic condition called Familial Hypercholesterolemia (FH) or Familial Combined Hyperlipidaemia (FCH).
Seafood is also an excellent source of omega-3.
