Which groups are affected by certain chronic diseases, and which groups aren't? This depends on genetics (30%) and on the exposome (70%). By exposome, we mean all kinds of factors in everyday life, including what we eat and drink, the air we breathe, our social interactions and lifestyle choices such as smoking and exercise. The individual’s biological response to these factors also forms part of this exposome. Much remains to be discovered about the exposome, and therefore about the development of chronic diseases. A consortium led by Professor Roel Vermeulen, affiliated with Utrecht University and University Medical Center Utrecht, will investigate which factors of the exposome are important for health and how these factors work. To this end, the consortium has been awarded 17,4 million euros from the prestigious Gravitation Grant. The participating institutes themselves are contributing more than 8 million euros.
Vermeulen: 'In their daily lives, people make all kinds of choices that have a major impact on their health. Thanks to the grant, we are able to identify all non-genetic risk factors for the health of the Dutch population.' Much is already known about the human genome, and the researchers now also wish to systematically analyse the human exposome for the first time. 'We know that the disease burden of people with chronic illness is largely influenced by the exposome. That’s why this grant is so important. We will start by researching the causes of cardiovascular disease and type 2 diabetes. The techniques and insights from this study can also be applied to other chronic conditions.'
