Routine hospital diets: clear liquid, full liquid, soft and normal
Hospital diets change in consistency: clear liquid, full liquid, soft, then normal. A patient moves up the ladder as tolerated.
Draw it: the diet ladder
Not every patient climbs every step. A patient after minor surgery may go straight from clear liquid to soft.

Other hospital diets you should know
- Mechanical soft (minced) diet: normal foods minced, mashed or ground, for patients without teeth or with jaw problems.
- Bland diet: free of irritants such as chilli, pepper, strong spices, coffee and alcohol; once used for peptic ulcer, now kept for patients who feel pain with these foods.
- Light diet: between soft and normal; plain, easily digested foods with little fat.
- Tube feeds: liquid feeds given through a tube when the patient cannot eat (see enteral feeding).
In the ward the dietitian checks the diet order on the case sheet each morning and moves the patient up the ladder as soon as the doctor allows. A patient left on clear liquids for days loses weight fast.
