Final answer:
Cooked split peas contain the most fiber compared to the other food choices, which is significant for those on a high-fiber diet like individuals with diverticular disease.
Step-by-step explanation:
The student asked which of the following food choices by a client who has diverticular disease and is prescribed a high-fiber diet contains the most fiber: White rice, Canned peaches, Whole wheat bread, or Cooked split peas.
Among the items listed, cooked split peas are the richest source of dietary fiber. Whole grains, legumes (such as split peas), vegetables, and fruits are recognized as excellent sources of dietary fiber. This type of fiber is essential for promoting healthy digestion and may benefit in reducing risks of various conditions like coronary heart disease and colon cancer. In contrast, white rice, particularly when refined, is low in fiber. Canned peaches may contain some fiber, but less than whole fruits due to processing. Whole wheat bread is a better source of fiber compared to white bread but still not as high in fiber as legumes like split peas.
