Residents who are on a low-residue diet must limit which type of foods?

1. Foods that are spicy

2. Sugary foods

3. Foods that are high in fiber

4. Low-fat foods

The correct answer is: Foods that are high in fiber

A low-residue diet is designed to reduce the frequency and volume of stools, making it particularly beneficial for individuals with gastrointestinal issues or those preparing for certain medical procedures. In this diet, the primary focus is on limiting the intake of foods that are high in fiber, as fiber contributes to bulk in the digestive system, which can lead to increased stool production. High-fiber foods include many fruits, vegetables, whole grains, seeds, and nuts, all of which should be minimized or avoided entirely in a low-residue diet. This helps alleviate stress on the digestive tract and can aid in managing conditions such as inflammatory bowel disease, diverticulitis, or before surgeries related to the bowel. In contrast, spicy foods, sugary foods, and low-fat foods do not directly relate to fiber content; thus, they do not have the same impact on residue in the intestines. Therefore, the primary focus on limiting high-fiber foods is what makes this diet effective.
