Juicing is the method of extracting juice from a fruit or vegetable, leaving the fiber and pulp collected in the machine. You can combine handfuls of green, leafy produce with a few fruits for a tasty liquid combination.
A smoothie is a blend of whole foods. The whole food is blended into a thick drink, using all the fruit except for nonedible things like banana peels or certain seeds. Smoothies generally have a thick, creamy texture.
