Nutritional biomarkers and machine learning for personalized nutrition applications and health optimization

The doctrine of the "one size fits all" approach in the field of disease diagnosis and patient management is being replaced by a more per patient approach known as "personalized medicine". In this spirit, biomarkers are key variables in the research and development of new methods for prognostic and classification model training based on advances in the field of artificial intelligence [1-3]. Metabolomics refers to the systematic study of the unique chemical fingerprints that cellular processes leave behind. The metabolic profile of a person can provide a snapshot of cell physiology and, by extension, metabolomics provide a direct "functional reading of the physiological state" of an organism. Via employing machine learning methodologies, a general evaluation chart of nutritional biomarkers is formulated and an optimised prediction method for body to mass index is investigated with the aim to discover dietary patterns.
