"Clear liquids" are any transparent drinkable liquid. Like glass, it might have color, but you should still be able to see through it. Usually they contain mostly sugar and water (except for broths and bullion, which are salty). A strict clear liquid diet excludes all solids (even noodles in soup), milk products, and citrus (orange, grapefruit) juices. See the list below for a variety of clear liquid recommendations. They are only appropriate for adults and children over 3 years.
