A group of investigators in Europe looked at the relationship between risk for colorectal cancer and adherence to the Mediterranean Diet in the European Prospective Investigation into Cancer (EPIC) and Nutrition study. For the EPIC study about 520,000 apparently healthy people were recruited from 1993-2000 in 23 research centers in 10 European countries. After an average follow-up of around 11 years the researchers found evidence that suggests that adherence to a Mediterranean Diet is associated with moderately reduced risk of colorectal cancer.
