Personalising stuff that doesn’t matter

What is actually worth tracking?

The problem with personalised nutrition industry is that this is still a young research field, and there is not yet good enough evidence across the field to believe that we have yet found worthwhile novel interventions that are more helpful than standard advice. Although a Food Standards Agency report stated last year that “glucose monitoring and gut microbiome analysis may prove to become more robust and actionable” it spoke for many experts when it concluded that “the benefits of PN seem somewhat marginal when compared to what is already understood about a healthy diet.” More here.

I guess that fitness trackers, for all of their inaccuracies, are dealing with factual metrics. The problem with so many other apps and tests is that they do seem to offer far too much which can only be assumed. They, however, dress it up as definitive.
