Omega-3 fats are polyunsaturated fats. Oil-rich fish such as Scottish salmon, mackerel and herring are naturally rich in long-chain omega-3 fats, especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These ‘ready-made’ long-chain omega-3 fats in oily fish are linked to various health benefits.

One of the main benefits of the long-chain omega-3 fats EPA and DHA is the role they play in helping to keep the heart working normally. In particular, these fats help to maintain blood levels of triglycerides, a type of fat in the blood, which when raised increases our risk of heart disease.

Omega-3 fats are known to play a role in helping to maintain normal blood pressure. Other benefits include: helping to maintain normal brain function and brain development in babies; and helping to maintain good eyesight.

According to The Scientific Advisory Committee on Nutrition all you need to do is eat two portions of fish a week, including one oily variety – and you’ll get enough long-chain omega-3 fats in your diet.
