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?
