Colorectal cancer prevention: simple diet and lifestyle habits recommended

Colorectal cancer is one of the most common cancers in France, affecting tens of thousands of people each year. Health specialists stress that daily habits can significantly lower risk. Eating several portions of fruits and vegetables daily provides fiber, vitamins and antioxidants that support intestinal health, while limiting ultra‑processed foods, processed meats and excessive alcohol reduces inflammation and harmful microbiome changes.

Medical experts also highlight tobacco cessation as crucial, as smoking increases oxidative stress in colon cells. A French gastroenterologist notes that “a diet rich in raw, minimally processed produce and low in processed meat is a key protective factor.” In a separate interview, US oncology dietitian Nichole Andrews advises three concrete actions: eliminate alcohol altogether, avoid taking dietary supplements without medical guidance, and remove processed meats such as bacon and sausage from the diet. These combined lifestyle changes are presented as practical, everyday measures to protect against colorectal cancer.
