Fish and Nutrition
High in protein, fish is an outstanding source of nourishment and is recommended as an essential part of a healthy, balanced diet. A 100g portion of fish supplies you with a third to half of your daily protein needs. As the primary source of high-quality protein, fish makes up 14-16 per cent of the animal protein consumed worldwide.
Apart from protein, it’s also packed with essential amino acids, and contains vital nutrients such as B-vitamins, macro-minerals such as calcium and trace elements such as iron. All of these are vital for good health and the optimum functioning of the body.
Oil-rich fish, such as salmon, trout, mackerel, herring and sardines, are an excellent source of Omega-3 fatty acids, which are essential to our diet. Omega-3 fatty acids cannot be manufactured by the body so it is important that we bring them into our diet and eating oil-rich fish provides the Omega-3 fatty acids we need.
Oily fish which contain a lot of with Omega-3s can:
- help to reduce the risk of death after heart attack;
- help to prevent blood clots from forming and prevent the heart from developing an irregular rhythm;
- help to lower blood pressure;
- help to raise good cholesterol levels (known as HDL cholesterol) in the blood, which helps to prevent cholesterol being deposited in the artery wall;
- help to lower the level of fats in the blood, high levels of which are a risk factor for heart disease;
- Contribute to normal development of the fetal brain;
- Prevent and treat depression;
