How do I differentiate a nutrition or supplement fad from information that I can really trust to improve my health and help me feel better?

There’s no guaranteed path to an easy answer.  My suggestion is to get acquainted with http://scholar.google.com and their ‘advanced search’ functions.

  • Find clinical articles that support (or counter) the claims being made.  If there are multiple (10+) studies, I would say there’s a foundation.
  • Also keep an eye out for clinical reviews.  These are usually bodies of work that summarizes the findings of multiple studies.  Keep in mind that clinical studies aren’t cheap and often require sponsorship.  Keep in mind who is paying for the study as they are likely involved in the planning and have intention behind the results (Drug Company vs. University).
  • Some studies include a ‘weaknesses/limitations’ segment as well as a ‘conflict of interest’ statement.  If these are present, that’s a good sign.  If there’s substantial information in the weaknesses/limitations segment, that shows due diligence was done and an effort towards honesty was made because every clinical study has limitations. 
  • My final piece of advice: don’t buy in to the marketing materials.  Visuals and word choice is an entire industry.  Instead, look for the tiny asterisks and the referenced articles/studies in the small print.  Scientists are not marketing professionals so their information, although less vibrant and flashy, will be more straightforward.
