04 Jun 2020 --- An international team of researchers has developed whole-body computational models to further propel research into personalized medicine, including the role of diet on the microbiome. Named Harvey and Harvetta, the virtual humans successfully predict known biomarkers of inherited metabolic diseases and enable the exploration of potential metabolic interactions between humans and their gut microbiomes at a personal level. They are touted as enabling the creation of personalized whole-body metabolic models using an individual’s physiological, genomic, biochemical and microbiome data.
