Putting the Grey and Bolland Research Letter into Perspective

It is easy to forget that science works through a constant process by which researchers replicate and revisit older studies. The assumptions and conclusions are discussed, the experiment is replicated, sometimes in a different population, sometimes using a slightly different dosage or research methods, and our knowledge grows, step by step. This may seem cumbersome, but it is necessary (the inevitable mistakes get corrected over time), and is actually one of the greatest strengths of the scientific process.

This, however, can also produce studies whose results and conclusions can contradict each other. In the omega-3 world examples can be found in the ongoing research on the related questions of:

  • Do EPA and DHA reduce the risk of chronic diseases and health events, like cardiovascular disease and strokes?
  • How big is this protective effect, and who benefits more and who less from it?
  • What is the best way to achieve this protection?

GOED's New Zealand Oxidation Paper Published

A new scientific paper authored by GOED and some of its members that attempted to replicate the findings from a paper in 2015 by Albert et al has been published in Scientific Reports. The original paper controversially claimed nearly all fish oil supplements in New Zealand did not contain the EPA and DHA stated on the label and were excessively oxidized. The GOED study found that nearly all — 96% — of the products tested complied with regulatory limits for oxidation for edible oils and 91% complied with label claims about EPA and DHA content.
