Abstract
Personalization of nutrition advice is a process already familiar to registered dietitian
nutritionists, but it is not yet clear whether incorporating genetic results as an
added layer of precision improves nutrition-related outcomes. Therefore, an independent
workgroup of experts, supported by the Academy’s Evidence Analysis Center staff, conducted
a systematic review to examine the level of evidence measuring the effect of incorporating
genetic testing results into nutrition counseling and care, compared to an alternative
intervention or control group, on nutrition-related outcomes. This systematic review
revealed that only weak quality evidence is available in the scientific literature
and observed that this field is still maturing. Therefore, at present, there is insufficient
scientific evidence to determine whether there are effects of incorporating genetic
testing into nutrition practice. The workgroup prepared this Consensus Report based
on this systematic review to provide considerations for the practical application
of incorporating genetic testing into the nutrition care process.
