Including regular portions of fish rich in omega-3 fatty acids, such as salmon and mackerel, may lengthen your life.
New research has found a connection between having a higher level of the omega-3 in a person's blood and a lower risk of death, particularly from heart disease.
The study published in Annals of Internal Medicine looked at 2,600 older adults and found those who ate more fish lived on average two years longer than those with lower omega-3 levels.
None of the participants took fish oil supplements at the time, getting their heart-healthy fish oils from foods such as salmon, mackerel and herring.
'This is not a study of fish oil supplements, it's a study of blood omega-3 levels related to diet,' said researcher Dr. Dariush Mozaffarian, an associate professor of epidemiology at the Harvard School of Public Health in Boston.
Fish oils have long been linked to healthier hearts, and this study found that those studied with the highest amount of omega-3 in their blood had a 35% lower risk of dying from heart disease.
The issue with the research is that it is difficult to separate fish eating from the rest of a person's lifestyle. Someone who eats a few portions of salmon a week may also live an overall healthier and active life than someone that doesn't.
Better bung a packet of mackerel in the shopping basket this week just in case though…
