What is one type of liquid that is NOT permitted in a clear-liquid diet?

In a clear-liquid diet, the primary objective is to provide hydration and minimal calories while allowing the digestive system to rest. Clear liquids are those that are transparent and can be seen through, ensuring that they leave little residue in the gastrointestinal tract.

Milk, while a liquid, does not fit the criteria for a clear-liquid diet because it is opaque and contains fats and proteins that can be hard to digest and leave residues. This can interfere with the purpose of the diet, which seeks to keep the intestines clear and free from any substances that require more extensive digestion.

In contrast, options like fruit juice without pulp, water, and popsicles are all considered appropriate for a clear-liquid diet. These liquids are transparent and do not leave a residue, making them suitable for patients who may be recovering from surgery, experiencing gastrointestinal issues, or preparing for medical procedures.
