Adherence
Adding phenotypic and genotypic data to personalized nutrition advice does not provide added benefit over advice based solely on current diet analysis.
Do not pay for expensive genetic or phenotypic testing for personalized nutrition advice. The Food4Me study showed that advice based only on your current diet is just as effective as advice that includes your genes or body metrics.

However, including more complex phenotypic and/or genotypic information in developing the personalised nutrition advice had no added benefit.
Why this rating
Based on the Food4Me RCT which compared levels of personalization.
