Citando:
"(...) The most widely used method to assess diet – self-reporting – is notoriously unreliable.
Study after study has found that most people are prone to under-reporting the amount of unhealthy food they eat while over-reporting the amount of healthy food.
In this small study, on four separate occasions, 20 participants consumed four different diets which were assessed as ranging from very healthy (in terms of agreeing with international guidelines) to unhealthy.
Urine samples were tested for substances known to be associated with certain types of dietary patterns (metabolic profiles).
The researchers found that urine tests were in fact robust enough to identify dietary patterns in the participants – the levels of 19 substances (metabolites) were significantly higher in the healthiest of the four diets compared with the unhealthiest.
As this study had a very small sample size, it's likely that more research will be needed to verify the findings, before considering how best urine tests could be adopted as a dietary tool for health services."
