Claims have been made that the smoothie was invented by Stephen Kuhnau in the late 1960's. Since 1920's, Orange Julius has been making a beverage very similar to smoothie. A smoothie is a beverage (non alcoholic) made from natural ingredients, generally juices and fruits. Natural flavours like peanut butter and chocolate are sometimes used to make it exciting. Partially frozen beverages use ice or frozen fruit. Although they sometimes appear like milkshakes, they do not contain dairy products like ice cream. They appear like milkshakes because they have a thicker consistency unlike slush drinks. Smoothies are often made with nutritional supplement mixes and vitamin and target health conscious people. To get their creamy and thick texture, many smoothies depend on bananas. They are often mixed with alcohol or soda pop to make a cocktail.
