Agreed - ideally, in the "kitchen of the future":
1. You'd go online, find a recepie for the upcoming meals you'd want to make.
2. Your network connected fridge and pantry would take inventory of what you have, and automatically make a grocery list, or contact somewhere to have the raw ingredients delivered. Also, it could let you know when things need to be used by, are expired/etc.
3. Based on the above, generate a description of caloric intake, etc.
The hardware/software integration to make this happen would take a lot of work...
