Which food item should be avoided on a low residue diet?

A low-residue diet aims to reduce the amount of undigested food or fiber that passes through the digestive system, making it easier for the intestines to heal. Foods that are high in fiber, such as raw fruits, can increase stool bulk and stimulate bowel activity. Therefore, they should be avoided on a low-residue diet.

Buttered rice, sponge cake, and white bread are typically lower in fiber and would be considered more suitable options for someone following a low-residue diet. Buttered rice and white bread are generally soft, processed foods that do not contribute much to fecal bulk. Sponge cake, while more sugary, also does not contain significant fiber, making it acceptable in moderation.

In summary, the avoidance of raw fruits is due to their high fiber content, which is not appropriate for a low-residue diet aimed at reducing digestive workload.
