BioTransform is a multidisciplinary doctoral network (DN) aiming to investigate the role of health promoting constituents found in food products (food bioactives – FB), focusing on their metabolism. Even though the role of the gut microbiome is nowadays considered imperative in health homeostasis  and disease prevention, the available information regarding gut microbiome-driven FB biotransformations after food intake remains scarce and highly unexplored even regarding common food products. Thus, the goal of BioTransform is to combine state-of-the-art methods, technologies and approaches in a complementary and integrated way to reveal the role of metabolism in the digestive tract, and the impact of FB and their metabolites (biotransformation products) on health and disease. To this end, human pilot studies, in vitro and in silico metabolism simulation methods, gut microbiome sequencing, metabolite profiling and metabolomics will be employed. The BioTransform objectives will be accomplished through 11 complementary doctoral projects from 9 education and research entities, additionally including the participation of 6 associated partners from the private sector and one from academia.
