Which diet consists of foods that are liquid at room temperature and leave little residue in the intestine?

• A. Clear liquid diet
• B. Full liquid diet
• C. Regular diet
• D. Mechanical soft diet

Answer: (A)

The main idea is to rest the digestive tract and minimize solid residue by using fluids that are clear and pass through the GI tract with little or no solid material. A clear liquid diet fits this exactly because it is made up of liquids that are transparent at room temperature. These fluids provide hydration and some energy but leave almost no stool residue, making them suitable for short-term use before or after procedures or when the GI tract needs a gentle rest. Examples include water, broth, clear fruit juices without pulp, tea or coffee (without dairy), and gelatin.

In contrast, a full liquid diet adds liquids and some liquefied foods that aren’t completely clear (such as milk, strained soups, yogurt, and ice cream), which can produce more residue. A regular diet includes solids and fiber, producing more residue, and a mechanical soft diet includes soft solids rather than liquids.
