Objectives: observational, cross-sectional and longitudinal studies have evidenced that obesity rates and
associated complications such as type 2 diabetes, dyslipidemia, liver steatosis and cardiovascular events
are continuously rising as a health burden with increasing costs. In this context, subjects elicit variable
responses to the dietary intake depending on phenotypical and genotypical factors whose understanding
is helping to provide Precision Nutrition management.
Nutriomics offer a huge prospect to feature and assess the variety in the reactions to diverse nutritional therapies as well as for medical applications. Research on candidate genes together with Genome Wide Association Studies (GWAS) and meta-analyses of GWAS have characterized a number of polymorphisms associated with cardiometabolic and liver related adverse features, while nutrigenetics is involved in the recognition of genediet interactions, putatively explaining phenotypical differences accompanying food and dietary consumption.
In addition to discover differences associated to the genetic make-up, transcriptomic strategies measuring mRNAs levels have found that the energy intake plus nutrient contents and quality could affect the expression of genes involved in fuel intermediate metabolism, insulin signalling, lipid turnover, and inflammation in different organs and cells such as liver and adipose tissue . Further studies have revealed the occurrence of epigenetic processes (mainly DNA methylation, covalent histone modifications and miRNAs) that may modulate gene functions and participate in nutrition-related diseases and personalized differences.
The investigation of newer metabolomic biomarkers is essential to progress in the evaluation of patient’s metabolic dysfunctions and unhealthy conditions, which will enable to better define health and disease statuses and discriminate responders from non-responders to a given nutritional prescription. Also, metagenomics researches have demonstrated that lifestyle factors such as diet or physical activity can impact intestinal microbiota composition, with possible influence in body weight homeostasis/maintenance, type 2 diabetes, cardiovascular or liver diseases. Integration in the near future of omics data into Precision Nutrition will allow the implementation of personalised nutritional treatments to prevent and manage chronic diseases and to monitor the individual’s response to novel therapeutical interventions.
