Eating plenty of fish can 'reduce chances of ill health in retirement age by a quarter', major study finds

• News & Highlights

Eating a diet rich in oily fish can reduce people’s chances of ill health in retirement by up to a quarter, researchers found. A study of more than 2,500 pensioners found those with higher blood levels of omega-3 fats were 24 per cent less likely to develop age-related illnesses such as dementia, heart disease and cancer.

The essential fatty acids – found in seafood such as salmon, mackerel and sardines – are known to boost the brain, heart and vision.

Now scientists say they could help the population remain in good health for longer. They believe omega-3 polyunsaturated fatty acids, known as n-3 PUFA, help regulate blood pressure, heart rate and inflammation.
