Purpose of review: The purposes of the present review are to examine the emergence of nutrigenetics/nutrigenomics, to analyze the relationship between nutrigenetics and nutrigenomics, to explore the impact of nutrigenetics/nutrigenomics on healthcare with respect to noncommunicable diseases, and to discuss the challenges facing the implementation of nutrigenetics/nutrigenomics within healthcare.
Recent findings: Nutrigenetics/nutrigenomics is certainly a thriving specialty given the sharp increase of publications over the last two decades. The relationship between nutrigenetics and nutrigenomics is proposed as complementary. The current clinical and research literature supports the significant impact nutrigenetics/nutrigenomics has on treating and preventing noncommunicable diseases. Although several challenges face the implementation of nutrigenetics/nutrigenomics into healthcare, they are not insurmountable. Nutrigenetics/nutrigenomics plays an important role not only in treating diseases and illnesses but also in promoting health and wellness through both basic and clinical research; and it is critical for the future of both personalized nutrition and precision healthcare.
