Which of the following best describes a low-residue diet?

A low-residue diet is specifically designed to limit the intake of fiber and indigestible substances, making it easier for the digestive system to process food. This type of diet can be beneficial for individuals with certain gastrointestinal issues or those preparing for surgery or medical procedures that require minimal bowel activity. By reducing fiber, the diet helps decrease the volume and frequency of stool, which is crucial for managing symptoms associated with various digestive disorders.

The focus on fiber reduction is key, as fiber can increase intestinal bulk and lead to more frequent bowel movements, which may not be desirable in certain medical scenarios. Therefore, the correct description of a low-residue diet is that it limits fiber and indigestible components, supporting better digestive health in specific situations.
