N-3 in fish & beef/milk

Summary

This paper, published in the British Journal of Nutrition in 2009, examines and compares the omega-3 (n-3) polyunsaturated fatty acid content of fish, beef and dairy products, likely drawing on food composition data and dietary intake modelling. The study appears to evaluate the relative importance of these food sources as contributors to long-chain n-3 fatty acid intake in the diet. It is likely to highlight that whilst fish remains the predominant source of EPA and DHA, ruminant products such as beef and milk also contribute meaningful quantities of n-3 fatty acids, particularly from grass-fed animals.

UK applicability

Although the study appears to be based in Belgium, the findings are broadly applicable to UK dietary and food policy contexts, particularly regarding recommendations on n-3 intake from both marine and terrestrial animal sources and the potential nutritional value of pasture-fed beef and dairy within UK production systems.

Key measures

Omega-3 fatty acid concentrations (mg per 100g or per serving); estimated dietary intake contributions from fish, beef and milk

Outcomes reported

The study likely measured and compared the concentrations of long-chain omega-3 fatty acids (EPA, DHA, ALA) in fish, beef and dairy products, assessing their relative contributions to dietary n-3 intake in a population context.
