3D printers start printing food

A recent study by MIT demonstrated how to increase satiety with smaller portions.

The CSAIL HCI engineering group have conducted a study, during which they learned that the shape or form of food is directly related to the sense of satisfaction that a person experiences during eating. For example, if you increase the volume of space taken up by the portion on the plate, then a sense of fullness will come faster. The texture of our food is also important: the more chewing required, the greater the level of fullness.l.

A 3D printer with a specialised nozzle was used to print an edible paste-like mass.  Dishes which were  identical in nutritional value, but different in form and texture were created. 

Then, printed food was offered to thirty participants in the experiment, whose reactions were recorded with the help of electromyography sensors. Based on these findings, the scientists have developed the FoodFab system - a 3D food printer that can automatically create various food products. It may be widely adopted in medicine in the future.
