1. A scale comprising a weight sensor;
- a database memory for storing data related to single-valued nutritional indicators for a plurality of common foodstuffs wherein the single-valued nutritional indicators are based on caloric content of the foodstuff and at least one other nutritional attribute of the foodstuff;
user input means for identifying a foodstuff being weighed;
a processor for selecting data from the database memory related to the single-valued nutritional indicator for the identified foodstuff and for calculating a single-valued nutritional indicator for the weight of the identified foodstuff as detected by the weight sensor; and
means for displaying the calculated single-valued nutritional indicator for the weighed foodstuff.

14. A method of providing a total, single-valued nutritional indicator for a food serving or recipe containing plural foodstuffs using a scale with a weight sensor, database user input, processor and display comprising:
-
(a) placing a food vessel on the scale;
(b) zeroing the weight reading of the weight sensor;
(c) placing a foodstuff in the vessel;
(d) entering an identification of the foodstuff using the user input;
(e) employing the processor and database to provide a selected nutritional indicator per unit weight of the identified foodstuff and calculating a single-valued nutritional indicator for the weight of the identified foodstuff sensed by the weight sensor;
(f) repeating steps (b)-(e) at least once;
(g) calculating a total single-valued nutritional indicator for the foodstuffs in the vessel;
(h) displaying the total, single-valued nutritional indicator for the foodstuffs in the vessel. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A scale comprising:
-
a weight sensor;
a database memory storing a database of specific nutritional parameter values for a plurality of foodstuffs;
a display;
user input means for inputing information into the scale; and
processing means configured to be responsive to operations of the user input means for selecting nutritional parameter values from the memory and generating respective absolute nutritional parameter values in dependence on an output of the weight sensor, wherein the processing means is configured for accumulating a plurality of total nutritional parameter values, generated in response to a plurality of respective user input operations, using the user input means and controlling the display to display the resultant accumulated absolute nutritional parameter value. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
