A nurse teaches a client who is at risk for colorectal cancer. Which dietary recommendation would the nurse include?

Choice A reason: Low-fiber and low-residual foods are typically recommended for patients during acute flares of inflammatory bowel disease to rest the bowel. However, for cancer prevention, these foods are contraindicated because they increase transit time and the duration that potential carcinogens remain in contact with the intestinal lining. Choice B reason: Cruciferous vegetables like broccoli and cauliflower are high in fiber and contains chemopreventive compounds. High fiber intake increases stool bulk and decreases transit time, which dilutes potential carcinogens and reduces their contact with the colonic mucosa, significantly lowering the long-term risk of developing colorectal adenocarcinoma. Choice C reason: Diets high in animal fats are strongly associated with an increased risk of colorectal cancer. High fat intake increases the secretion of bile acids into the gut, which can be converted by intestinal bacteria into secondary bile acids that act as promoters of cellular mutation and malignancy. Choice D reason: While white rice and bread are refined carbohydrates that are easy to digest, they lack the essential fiber necessary for colorectal health. A diet heavy in refined grains is associated with higher glycemic loads and increased cancer risk, whereas whole grains are preferred for their protective fibrous qualities.
