How would nutrition research look like in 10 years, what infrastructures do we need and how do we make these?
1 – The world is my cohort • Classical epidemiology will be dead • E-health is accessible for research purposes • Everybody has open access to all cohort data • Virtual cohorts are created by personalized health monitoring and internet communication • Food intake quantification is obsolete, and fully replaced by ‘health biomarkers’
Not these … the “bowtie” principle food / intake absorbed / plasma Target organ concentration early effects late effects regulation of homeostasis and efficacy Individual variation THIS is the point from which nutrient requirements need to be derived
2 - My health is my concern • Personal health monitoring will be daily practice. • Access to my health information is normal: my genomic variation is determined and translated in life style advice • I have PDA-access to my health status, fed by a series of frequent bioassays in my home setting. • My electronic medical record is integrated • Food companies have evolved into life style companies, offering diet suggestions based on my lifestyle and monitored health status
Routine Analyses on Individual Patients with 10 years Copied from a presentation of Lee Hood Institute for Systems Biology, Seattle
Individual Patient High Throughput Assays of the Future Complete individual genome sequences—predictive health history—will be done sequencing families Sequence 1000 transcriptomes simultaneously in one DNA sequencing run from single cancer cells or single cells from biopsies--to stratify disease. 2500 blood organ-specific blood proteins—twice per year (50 proteins from 50 organs)—wellness assessment. Analyze 10,000 B cells and 10,000 T cells for the functional regions of their immune receptors—past and present immune responsiveness—follow vaccinations. Analyze individual stem (iPS) cells from each individual differentiated to relevant tissues to get important phenotypic information—molecular and imaging.
3 - Nutrition research • Extensive phenotyping is the keyword • Nutritional intervention studies are performed according to accepted standards and protocols • This allows seamless merging of study data and integration in WWW information sources. • Access to hundreds of ‘gold standard’ intervention studies creates a new virtual cohort and goldmine for ‘in silico nutrition’ research.
A major transition! Basic drivers • Technology becomes standard and cheap • Information becomes accessible • Results are shared • Participatory research
Divergence into 2 types of studies • Observational – “worldwide” • Interventional – extensive phenotyping
So what tools does nutrition research need? • Generic information systems • Dedicated nutrition research tools • A way to share, integrate and evaluate results
Generic information systems These are the tools that provide in depth generic biological information • Genetics and genetic variation databases • Genotype – phenotype translation tools • Protein-protein interaction databases • Transcriptome databases and bioinformatics • Pathway information and tools • Etc etc
Dedicated nutrition research tools • Food composition databases • Elaborate information on “nutrient biology” • Accepted research methodologies
A way to share, integrate and evaluate results • My results are mine until I decide to share, and with whom. • Once I decide to share, my results connect to all other results because the formats and methods are identical. • The advantages of sharing are so obvious that I cannot wait for the moment … We need an IT-infrastructure that facilitates this.

Results of the first nutritional metabolomics workshop We are now organizing the third – which is STUPID! Technology should be developed by the technology community These efforts are now alligned with the Metabolomics Society

Fundamentals of dbNP • Environment for extensive phenotyping in nutrition studies • Study driven instead of technology driven • All part stick to basic rules (a.o. ISA-tab) • Nobody owns - everybody contributes (open source community project) • You have your own local installation – free to adapt • All parts are modular – take out one, insert yours • example: Arraytrack, Base, Madmax: • input is the same: RNA-sample • Output is the same: annotated relative gene expressions • Made for nutrition research, applications are much broader • Nutrigenomics Organisation is ‘governing body’

Now that we know this, we can act accordingly … • A small problem: everybody needs it, nobody wants to do it. • (“Saturday morning projects”)
Datasharing IT network within NuGO:distributed information system • Control & IP remain with partner • Data and results are standardized • Software is centrally updated • “ready to share”

From NuGO to NuGO Infrastructure needs a global dimension, so we transform the European Nutrigenomics Organisation (NuGO) to the Nutrigenomics Organisation (NuGO)
So • The research infrastructure side of NuGO develops into a bridge between generic infrastructure (NCBI, EBI) and the nutrition research community • NuGO moves from European to Global • NuGO moves from a funded organisation to a community effort
Conditions for the optimal roadmapBetween Wild West and Kremlin?Between Chaos and Despautism? • Create a “servant leadership model”? • nobody owns • everybody is recognized • all contribute • complete data ownership • agreed standards • agreed agenda • Forget about ego`s • only ONE global roadmap
