Habitual intake of fruits and vegetables amongst patients at increased risk of colorectal neoplasia

« We assessed consumption of fruit and vegetables amongst patients with ulcerative colitis, colorectal polyps or previous carcinoma. The dietary intakes for 119 patients attending a gastroenterology clinic for colonoscopy were assessed using a questionnaire. A single age- and sex-matched control subject was recruited for each patient. The patients consumed 12.8% less energy than the controls (P < 0.02) and 28.9% less fruit and vegetables (P < 0.0001). Patients with neoplastic disease consumed 21% less fruit and vegetables than the controls (n = 60; P < 0.01). This group of patients at increased risk of colorectal cancer selected diets containing significantly less fruit and vegetables than symptomless controls."
