     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0017]     According to an embodiment of the invention, a nutrition tracking device may comprise a case of varying sizes and shapes, a screen to display numbers and text, a scanner, a scanner activation button, logic to aggregate data, and memory to store data. Additionally, the nutrition tracking device may comprise a wireless interface to a remote server for storage. The screen may be similar to that of a wireless text pager or a cell phone. The scanner is configured to scan nutrition codes located on a food container, inside a food container, or on a food item itself. A user may activate the scanner by pressing the activation button and then the user may scan the nutrition code. The nutrition code may contain nutrition information of the food item such as, for example, calories, fat, carbohydrates, protein, cholesterol, sodium, potassium, caffeine and/or vitamins (e.g., A, B, C, etc.). The nutrition information would be stored in the memory of the nutrition tracking device or remotely via a wireless interface to a remote server. The logic of the nutrition tracking device may aggregate the nutrition information over a predetermined time period (e.g., day, week, month, etc.). For example, one function of the nutrition tracking device may be to track the calories consumed over a day.  
         [0018]     Any food item may contain a nutrition code. For example, a fast food restaurant may provide food in an individualized one serving package containing a nutrition code on the package. The nutrition code would comprise all the nutrition information corresponding to the food contained in the package. For example, McDonald&#39;s may include a nutrition code on items it serves such as on a Big Mac wrapper, a French fry container, and a cola drink cup. A user may purchase these items, scan the nutrition codes on the food container, and consume the food items. The nutrition tracking device is configured to automatically store the nutrition information corresponding to the food items.  
         [0019]     The nutrition tracking device is configured to display nutrition information on a screen. The screen may continuously display nutrition information responsive to a user&#39;s input such as, for example, the overall calorie consumption for the current day. Additionally, other information may be displayed such as, for example, time, date, etc. The nutrition tracking device may allow a user to view stored nutrition information such as, for example, daily, weekly, and monthly nutrition information. The nutrition tracking device may comprise a scrolling wheel and/or alphanumeric keys for a user to access the nutrition information or it may comprise a voice activation and response system.  
         [0020]     The nutrition tracking device may be configured to allow a user to enter nutritional limits and to alert the user when the nutritional limits are approaching, reached, and exceeded. For example, a user may desire to limit daily caloric intake to 2,500 calories and fat intake to 20 grams per day. The nutrition tracking device may be configured to alert the user of these limits. An alert may be, for example, a sound or silent vibration. The alert could be set for any of the nutrition information tracked by the nutrition tracking device. Additionally, the nutrition tracking device may be configured to alert the user if a certain nutrition value is not reached. For example, a user may desire to consume 200 grams of protein by 4 pm each day. The device may alert the user as 4 pm approaches if the user is below 200 grams of protein for that day.  
         [0021]     The nutrition tracking device may also track nutrition codes from foods that come from a grocery store. For example, foods such as meat, poultry, bread, ice cream, etc. typically come in a package with several servings. The nutrition code on these food items may contain nutrition information corresponding to one serving size. For example, a user may have 2.5 cups of cereal, but the serving size may be 1 cup. The nutrition tracking device may be configured to allow a user to scan the nutrition code on the cereal corresponding to a serving size of 1 cup and then to use the input on the nutrition tracking device to enter 2.5 servings. Additionally, the nutrition tracking device may connect to an internal or external database either directly via a local connection (e.g., RS232, USB, and Ethernet) or via a wireless connection (e.g., WIFI). The database would allow for input of commonly eaten food items, odd sized food items, and food items without a nutrition code. A user may input a food without a nutrition code and connect to the database to download the corresponding nutrition information. For example, a user may input a banana into the nutrition tracking device and the device may connect to the database and download nutrition information corresponding to a banana. The database would also allow external storage of the nutrition information in the nutrition tracking device. For example, the nutrition tracking device may be synchronize with the user&#39;s personal computer with corresponding software to store, print, view, and analyze nutrition information.  
         [0022]     The nutrition tracking device may be contained in a case similar, for example, to a text pager. The case may be sized to fit on a key chain such as, for example, a key fob. Additionally, the functionality of the nutrition tracking device may be added to other devices such as a cell phone, a personal computer, or a PDA with the addition of a scanning device.

The local interface  19  may have additional elements, which are omitted for simplicity, such as controllers, buffers (caches), drivers, repeaters, and receivers, to enable communications. Further, the local interface may include address, control, and/or data connections to enable appropriate communications among the aforementioned components.  
         [0025]     The processor  14  can be any custom made or commercially available processor, a central processing unit (CPU), a semiconductor-based microprocessor (in the form of a microchip or chip set), or generally any device for executing software instructions. When the nutrition tracking system  13  is in operation, the processor  14  is configured to execute software stored within the memory system  15 , to communicate data to and from the memory system  15 , and to generally control operations of the nutrition tracking system  13  pursuant to the software. For example, the processor  14  may be configured to aggregate nutrition information based on a user input.  
         [0026]     The memory  15  may comprise, for example, any one or combination of volatile memory elements (e.g., random access memory (RAM, such as DRAM, SRAM, SDRAM, etc.)) and nonvolatile memory elements (e.g., ROM, hard drive, tape, CDROM, etc.). The memory  15  is configured to store the nutrition information in a nutrition database  18  and the executable instructions of the nutrition tracking device  13 . Additionally, the memory  15  may comprise external storage in a separate device such as a personal computer.  
         [0027]     The input interfaces(s)  16  may be used to receive user input and/or nutrition information. The input device(s)  16  may comprise, for example, a scanner configured to scan a nutrition code  12  and/or a keyboard for manual data input. The output interface(s)  17  may be used to display nutrition information and/or to provide data to an external device (e.g., computer, printer, etc.). The output device(s)  17  may comprise, for example, a liquid crystal display (LCD) screen, a universal serial bus (USB) connection to a computer, or any other computer synchronization device, among others.  
         [0028]     The nutrition tracking device  13  may be contained as a stand alone device, personal computer (PC), personal digital assistant (PDA), or cell phone, among others. The nutrition tracking device  13  in a stand alone device may comprise a portable case resembling a cell phone, pager, or PDA. Additionally, the nutrition tracking device  13  may be contained in a small case which may attach to a key chain such as, for example, a key chain fob. The nutrition tracking device  13  may be contained in an existing device such as a cell phone, pager, personal digital assistant (PDA), or computer.
