For almost 30 years, Europe has been looking into the link between cancer and diet. They created the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Funded by Cancer Research UK and other funders including the European Union, research was collected and added to the EPIC database. Managing this was helped by the World Health Organization’s (WHO) International Agency for the Research on Cancer (IARC). The scale was considerable, involving more than half a million people, enrolled at 23 research centers across 10 countries in Europe.
