There is good evidence that increased consumption of fish and dietary patterns with omega-3 LC PUFAs, including food supplements, are associated with the primary prevention of coronary heart disease by:
Risk factor reduction, e.g. blood pressure and blood triglycerides
Reduction of risk of coronary heart disease mortality (CHD)/fatal CHD events
Good fish and seafood sources of Omega-3
Tuna (fresh or frozen)
Filling the omega-3 nutrient gap
Individual fatty acids have unique biological properties and beneficial health effects.
Recommended dietary intake for EPA + DHA is 0.25 mg–2 mg/day for secondary prevention of coronary heart disease.
Globally and in the UK, typical intakes of marine omega-3 PUFAs are low.
Barriers to frequent fish consumption include taste, smell and concerns about bones, and choice of fish determines whether recommendations can be achieved.
Strategies for achieving recommendations for EPA + DHA are food based, specifically oily fish, fortified foods and food supplements.
Guidance for health professionals
It would seem prudent to encourage increased consumption of biologically active marine sources of omega-3 LC PUFAs for the general population.
Educational programmes to inform consumers about options to increase intake of marine omega-3 LC PUFAs.
