Colorectal cancer (CRC) represents the third most common type of cancer worldwide with high incidence rates in our country as well. Both dietary habits and lifestyle factors have a strong contribution in preventing colorectal cancer. A healthy dietary pattern based on adequate intake of fruit, non-starchy vegetables, and whole grains is associated with positive outcomes regarding CRC development. The aim of the present study was to evaluate the dietary intake of plant-based food and food groups, along with lifestyle habits of CRC patients. A case-control study was conducted during April 2015 – October 2017. Patients (n=151) recently diagnosed with CRC and undergoing conventional treatment were recruited from Medisprof Oncology Hospital. Controls (n=151) were selected randomly from generally healthy adults. Dietary and lifestyle data were collected during a face to face interview and the applied lifestyle questionnaire included 74 items. The results showed that intake of specific food groups with high content of bioactive components was significantly higher in the control group compared to the CRC group (p<0.05), even though overall vegetable intake was similar between groups (p=0.51). Results also showed significant lower intakes of fiber-rich foods such as whole grains, nuts and legumes in the CRC group.
