What is claimed is: 1. A device for preparing a fluid food with a desired consumption temperature on demand, the device comprising: (a) a first water reservoir which comprises a first controllable water outlet, a first heater operable to heat water in said first reservoir and a first thermal sensor

What is claimed is: 1. A device for preparing a fluid food with a desired consumption temperature on demand, the device comprising: (a) a first water reservoir which comprises a first controllable water outlet, a first heater operable to heat water in said first reservoir and a first thermal sensor operable to report temperature of water contained in said first reservoir; (b) a second water reservoir which comprises a second controllable water outlet, a second heater operable to heat water in said second reservoir and a second thermal sensor operable to report temperature of water contained in said second reservoir; (c) a first container for holding a formula, said first container having a first controllable dispenser for dispensing said formula; (d) a data-processor/controller operable to receive water temperature data from said first and second thermal sensors, further operable to calculate a quantity of water from each of said first and second reservoirs needed to mix with a quantity of said formula in order to prepare said fluid food at said desired consumption temperature, and further operable to control operation of said first and second controllable water outlets so as to dispense said calculated quantities of water for mixing with said quantity of formula, said data-processor/controller being further designed and configured to command alternating periodic heating of water in said first and second reservoirs to sterilization temperatures, said periodic heating being so controlled that at first times said first reservoir contains water at a temperature above said desired consumption temperature and said second reservoir contains water below said desired consumption temperature, and at second times said first reservoir contains water at a temperature below said desired consumption temperature and said second reservoir contains water above said desired consumption temperature, thereby enabling periodic sterilization by boiling of water in both said first and said second reservoirs, and also enabling said production of food at said desired consumption temperature by mixing of said formula with selected amounts of water from said first and second reservoirs. 2. The device of claim 1, wherein said data-processor/controller comprises a data processor and controller integrated on a single electronic chip. 3. The device of claim 1, wherein said data-processor/controller is programmed to boil water for a period of at least about 20 seconds during said periodic re-heating of water in said first and second reservoirs. 4. The device of claim 1, wherein least one of said first and second reservoirs is sealed such that steam produced by boiling water therein remains captured and reliquifiable upon condensation when cooled. 5. The device of claim 1, wherein said data-processor/controller is designed to periodically reboil water in said first reservoir at predetermined intervals. 6. The device of claim 5, wherein said data-processor/controller is designed to boil water about every 1-5 hours. 7. The device of claim 5, wherein said data-processor/controller is designed to boil water about every 2-4 hours. 8. The device of claim 5, wherein said data-processor/controller is designed to boil water about every 3 hours. 9. The device of claim 1, wherein said desired consumption temperature is about 25 to about 35 degrees centigrade, said data processor and said controller being designed and configured for determining said quantity of water from each of said first and second reservoirs needed to mix with said quantity of said formula in order to produce said fluid food at a consumption temperature of between 25 and 35 degrees centigrade. 10. The device of claim 1, further comprising a second container for holding at least one additional ingredient, said second container having a second controllable dispenser for optionally dispensing a quantity of said additional ingredient. 11. The device of claim 10, wherein said additional container is designed to dispense one of a group consisting of a food supplement, a medicament, and a flavoring. 12. The device of claim 1, wherein said data-processor/controller is operably coupled with a user interface, said user interface being for displaying information related to said fluid food and for accepting input related to said fluid food, such that said data-processor/controller controls dispensing of said quantities of water and said quantity of formula according to said input. 13. The device of claim 1, designed and constructed to be operable to dispense water from said first and second reservoirs and formula from said first container into a recipient suitable for feeding an infant. 14. The device of claim 1, designed and constructed to be operable to dispense water from said first and second reservoirs and formula from said first container into a recipient suitable for feeding an adult in need of liquid feeding. 15. The device of claim 1, wherein said container and said first controllable dispenser for dispensing said formula are designed and constructed so as to substantially avoid dispensing any of said formula such tat said first and second controllable water outlets will become contaminated with remnants of said formula. 16. The device of claim 1, wherein said first container is designed and constructed for recharging with said formula when depleted. 17. The device of claim 7, wherein said container is prepackaged with said formula and is disposable when depleted. 18. The device of claim 1, wherein said container is designed and constructed to operably accept therein a prepackaged refill containing said formula. 19. The device of claim 1, wherein said data-processor/controller is operable to communicate information related to its operations via a communications network. 20. The device of claim 1, designed and constructed to be operable to dispense water from said first and second reservoirs and formula from said first container into a recipient suitable for enteral feeding. 21. The device of claim 11, further comprising a weight sensor operable to weigh a recipient for said fluid food before and after filling of said recipient. 22. The device of claim 1, wherein said data-processor/controller is further operable to calculate and to record amounts of food consumed by subtracting, from a recorded weight of a recipient containing freshly prepared food, a detected weight of said recipient subsequent to food consumption by a user. 23. The device of claim 1, wherein said data-processor/controller is operable to record and report times and amounts of food preparation.
