A clear or full liquid diet, or a diet containing no solid foods, is often prescribed for gastrointestinal illness or before or after certain types of surgery involving the mouth or gastrointestinal tract. A clear liquid diet consists of transparent liquid foods such as vegetable broth, bouillon, clear fruit juices, clear fruit ices, popsicles, clear gelatin desserts, and no carbonated drinks. Soda's carbonation expands the gastrointestinal tract. A full or strained liquid diet consists of both clear and opaque liquid foods with a smooth consistency. It includes milk, milkshakes, ice cream, puddings, strained cream soups, fruit nectar with pulp, smooth cooked cereals such as porridge and cream of wheat, butter, and honey. Fruit juices (without pulp), coffee, gelatin, popsicles (without pulp), water, and clear carbonated beverages are also acceptable.
