A dietary regimen composed exclusively of transparent liquids, easily digestible and leaving minimal residue in the digestive tract. Examples include clear broths, plain gelatin, strained fruit juices (without pulp), and certain clear beverages such as tea or clear sports drinks. The primary characteristic is the ability to see through the fluid clearly when held up to the light.
This type of diet serves a crucial role in preparing the body for specific medical procedures, such as colonoscopies, or in the initial stages of recovery from certain surgeries or gastrointestinal illnesses. The restricted nature of the intake minimizes strain on the digestive system, promoting healing and reducing the risk of complications. Historically, such regimens have been employed to allow the gastrointestinal tract to rest and recover from various ailments.
