People usually drink smoothies from a tall glass or cup, and use a plastic drinking straw to suck it into their mouth. Some dieticians think that drinking smoothies is not as good as eating the original fruit, because the smoothie has less fibre, and does not provide exercise for the jaw and other digestive processes which eating the fruit would give.
Smoothies are similar to milk shakes. Milk shakes are also a cold drink made with an electric blender. Milk shakes are usually made with milk, ice cream, and sweet syrups, such as chocolate syrup.
