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.

Victor de la O Pascual

Postdoctoral Researcher | Precision Nutrition and Cardiometabolic Health

Víctor de la O Pascual is a postdoctoral researcher who obtained his Dietetics and Nutrition Degree from the University of Navarra in Pamplona in 2017. During the last five years, he has actively contributed to the field of preventive medicine and public health as part of the School of Medicine at the University of Navarra in Pamplona, working under the guidance of Prof. Miguel Ángel Martínez-González. His research during this period has been dedicated to the investigation of the impact of dietary patterns rich in protein and protein/amino acid sources on cardiometabolic health. In 2022, Víctor successfully completed advanced studies and earned a doctoral degree in Applied Biomedicine, specializing in Preventive Medicine, Public Health and Biostatistics in the University of Navarra. His doctoral research was conducted under the supervision of Prof. Miguel Ruiz-Canela, chair of the department. Currently, Víctor’s primary research focus revolves around the cutting-edge fields of biostatistics, Big Data analytics, and the development of machine learning models within the realm of precision nutrition and medicine. He is a key member of the Precision Nutrition and Cardiometabolic Health program at IMDEA Food, where he works closely with Professor J. Alfredo Martínez. His contributions are instrumental in harnessing data-driven insights and applying them effectively to enhance our understanding of precision nutrition and medicine. Throughout his career, Víctor has made significant contributions to several research projects, with a particular specialization in Big Data analysis derived from randomized clinical trials in nutrition and chronic diseases. His work encompasses the analysis of models exploring conditions such as cardiovascular disorders and cognitive decline. Additionally, he has also played a pivotal role in clinical trials investigating cooking habits and their influence on type 2 diabetes. Lastly, he has successfully applied advanced statistical models to analyse large observational studies, with a focus on both adult and pediatric cohorts.
