Aim: Nutrigenomics reflects gene–diet interactions. In recent years, the science of nutrigenomics has become more sophisticated. We seek to answer the question as to what this might mean for the dietetics profession.
Methods: We have critically reviewed recent developments in the area, and considered the importance of new business opportunities being opened up, which exploit the full potential of nutrigenomics for dietitians.
Results: Whereas early business models sold genetic test results through direct-to-consumer testing, new business initiatives move dietitians to a central role. This now provides a robust framework that can inform dietitians in their practice.
Conclusion: This field represents an important advance for dietitians.
