Fish is a superfood
Eating plenty of fish on a regular basis can help protect you from a range of serious diseases.
Fish is a superfood. Packed with vitamins and minerals, and a major source of omega-3 fatty acids, fish can help to protect against a range of diseases, from cancer to heart disease, depression to arthritis.
Research has shown that eating fish and shellfish regularly is beneficial to our bodies in many ways. Here are some great reasons to introduce a little more seafood into your diet:
Heart
It's no coincidence that fish-eating Inuit populations in the Arctic have low levels of heart disease; seafood is low in saturated fat and high in omega-3, which can both protect the heart from disease and lower the amount of cholesterol in the blood.
Circulation
Eating fish can improve your circulation and reduce the risk of thrombosis. The EPA and DHA – omega-3 oils – in seafood can save your body from having to produce eicosanoids, a hormone-like substance which can make you more likely to suffer from blood clots and inflammation.
Joints
Eating fish as a regular part of a balanced diet has shown to ease the symptoms of rheumatoid arthritis, a condition which causes the joins to swell up. Recent research has also found a link between omega-3 fats and osteoarthritis, suggesting that eating more seafood could help to prevent the disease.
Essential nutrients
Seafood provides the body with many essential nutrients which keep us running smoothly, including iodine, selenium, zinc and potassium. Iodine is important for the thyroid gland, and selenium makes enzymes which can help to protect against cancer. Fish and shellfish are also excellent sources of many vitamins, including vitamins A and D.
Depression
Seafood may also play a large part in preventing depression; research has highlighted links between low omega-3 levels and a higher risk of depression. Seafood could also help us to avoid Seasonal Affective Disorder (SAD) and post-natal depression.
Skin
Not only does omega-3 help to protect the skin from the harmful effects of the UV damage, but eating lots of fish can also help with the symptoms of skin conditions such as eczema and psoriasis. Fish is also a great source of protein, which is an essential ingredient of collagen, a substance which keeps the skin firm and flexible.
Brainpower
The human brain is almost 60% fat, with much of this being omega-3 fat. Probably for this reason, research has indicated that people who eat plenty of seafood are less likely to suffer dementia and memory problems in later life. DHA, an omega-3 fat found in seafood, has also been linked to improvements in children's concentration, reading skills, behaviour, and Attention Deficit Hyperactivity Disorder (ADHD).
