A liquid diet may be prescribed by a doctor to cleanse the intestines.
An all-liquid diet was a popular diet for patients in hospitals in the past, but today the diet is avoided except in instances when the gastrointestinal tract needs to be clear of digested food.
Reasons
The liquid diet is used to cleanse the intestines and stomach before surgery of these areas. It can also be used after surgery to get the patient's digestive system ready for solid foods again. People with conditions like diverticulitis may use a liquid diet during a flare-up.
Allowable Foods
Things such as water, clear broth and Popsicles are allowed. Also a patient can consume tea or coffee but with no creamer. Apple, grape and cranberry juice is allowed as long as the juice does not contain pulp. Liquid supplements like Boost or Enlive! are permitted.
Prohibited Foods
Anything with milk, like creamers or milkshakes, is prohibited. Also high acid juices like orange, grapefruit or tomato juice are on the do-not-drink list.
Risks
The liquid diet will keep you hydrated, but lacks sufficient calories and nutrients. According to the Baptist Medical Clinic, a person should only stay on the diet for three days.
