Can nutrition research effectively be assessed in an evidence-based medicine paradigm?
Are randomized clinical trials actually the "gold-standard" for nutrition research?
Although healthcare professionals and regulatory agencies have eagerly embraced evidence-based medicine to evaluate health claims, they never seem to get around to checking out whether this model actually fits the nutrition context.
Randomized clinical trials are usually very limited in their relevance to the general population and they impose many constraints that are not always suited to testing nutrients and dietary supplements.
The full spectrum of research available, including observational studies, provides better and more complete evidence of the benefits of dietary supplements.
Feedback on this issue will be interesting!
