With the emergence of the concept of precision nutrition and the need to understand individual responses to dietary interventions, it is an opportune time to examine the impact of these tools to date in human nutrition studies. Advances in our mechanistic understanding of dietary interventions were realized through incorporation of metabolomics, proteomics, and, more recently, metagenomics. A common observation across the studies was the low intra-individual variability of the omics measurements and the high inter-individual variation. Harnessing this data for use in the development of precision nutrition will be important. Metabolomics in particular has played a key role in the development of biomarkers of food intake in an effort to enhance the accuracy of dietary assessments. Further work is needed to realize the full potential of such biomarkers and to demonstrate integration with current strategies, with the goal of overcoming the well-established limitations of self-reported approaches. Although many of the nutrigenomic studies performed to date were labelled as proof-of-concept or pilot studies, there is ample evidence to support the use of these technologies in nutrition science. Incorporating omic technologies from the start of study designs will ensure that studies are sufficiently powered for such data. Furthermore, multi-disciplinary collaborations are likely to become even more important to aid analyses and interpretation of the data.||Funding Details:||European Research Council||Funding Details:||Scottish Government’s Rural and Environment Science and Analytical Services Division||Type of material:||Journal Article||Publisher:||Oxford University Press||Journal:||The American Journal of Clinical Nutrition||Volume:||113||Issue:||3||Start page:||503||End page:||516||Copyright (published version):||2021 the Authors||Keywords:||Humans; Weight loss; Nutritional status; Eating; Research design; Nutrigenomics; Biomarkers; Precision medicine||DOI:||10.1093/ajcn/nqaa366||Language:||en||Status of Item:||Peer reviewed||ISSN:||0002-9165||This item is made available under a Creative Commons License:||https://creativecommons.org/licenses/by-nc-nd/3.0/ie/|
