The study
Various nutritional and lifestyle factors affect the risk of developing colorectal cancer. A Western dietary pattern for example increases this risk. A typical Western diet consists of much red meat, processed meat and alcohol and barely any vegetables and fruits. Furthermore, overweight people have a higher risk of developing colorectal cancer, whilst physical exercise reduces the risk.

But are nutrition and lifestyle also important after the diagnosis?
Is it possible for a patient to influence his/her disease by living a healthier lifestyle or by eating healthier?
Should he/she refrain from eating certain food products?
Is it beneficial to start taking dietary supplements during and after the treatment?

There is still no clear answer to all these questions. In this study, we collect all kinds of data from colorectal cancer patients in order to enable us to answer these questions.
