1. System for holding food in a ready-to-serve state, comprising one or several heat-conducting plates ( 6) on which the food can be placed, either directly or in dishes, in ready-to-serve fashion; one or several Peltier elements or similar devices and one or several heating elements, each of which is or can be thermally coupled to the plate(s) ( 6) and/or to the dishes; one or several selector switches ( 22) as operating controls or the radio-signal receivers of such selector switches by means of which it is possible to select temperatures and/or temperature cycles and/or warming or cooling modes of the plate(s) (6), as well as a control unit by means of which, in response to the selection made via the selector switches (22), the Peltier element(s) can be enabled to cool the plate(s) and/or the Peltier element(s) and/or the heating element(s) can be energized to heat the plate(s).2. System as in claim 1, in which, by employing the heating elements, the plate(s) (6) can be heated more rapidly and/or to higher temperatures than is possible with the Peltier element(s) alone.3. System as in claim 1, in which the heating element(s) is/are mounted under the bottom surface of the plate(s) (6).4. System as in claim 1, in which the heating element(s) is/are in the form of planar sheet- and/or foil-type and/or thin-film and/or screen-printed heating elements.5. System as in claim 1, in which the plate(s) (6) consist(s) of a glass ceramic.6. System as in claim 1, in which the plate(s) (6) is/are mounted on a circular horizontal frame (10) supported by a base (8) with a closed bottom.7. System as in claim 6, in which the plate(s) (6) can be snapped onto the frame (10) and/or the frame (10) can be snapped onto the base (8).8. System as in claim 6, in which the dimensions of the circular horizontal frame (10) including the slide rails and/or the base (8) correspond to one or several standards of the restaurant trade, bakers' trade or Eurostandards.9. System as in claim 6, in which the frame (10) and the base (8), as viewed from the side, are symmetrical in mirror-image fashion.10. System as in claim 6, in which the frame (10) accommodate the selector switches (22) and/or their radio-signal receivers and/or the control unit.11. System as in claim 6, in which the base (8) accommodates a power supply and/or a cooling fan.12. System as in claim 6, in which the base (8) is provided on its bottom surface with two mutually parallel skids (16) as well as specifically adjustable support feet.13. System as in claim 1, in which the Peltier element(s) is/are positioned next to the bottom surface of the plate(s) (6) and/or next to the bottom surface of the heating element(s).14. System as in claim 1, in which the plate(s) is/are heated by means of the Peltier element(s) according to the temperature and/or temperature cycle selected.15. System as in claim 14, in which the temperatures and/or temperature cycles selected are warming temperatures or warming cycles, respectively.16. System as in claim 1, in which the plate(s) is/are heated by means of the heating element(s) according to the temperature and/or temperature cycle selected and, specifically, cooking temperatures in excess of 100° C. (212° F.) can be attained.17. System as in claim 1, in which the plate(s) is/are heated by means of both the Peltier element(s) and the heating element(s).18. System as in claim 16, in which the temperatures and/or temperature cycles selected are warming or cooking temperatures or, respectively, warming or cooking cycles.19. System as in claim 1, in which the plate(s) is/are cooled by means of the Peltier element(s) in accordance with the temperature and/or temperature cycle selected.20. System as in claim 19, in which the temperatures and/or temperature cycles selected are cooling temperatures or cooling cycles.
