Diet Barcode

A device that can be used to monitor diet by scanning nutritional info
  [vote for,

This idea is for a device that would be used primarially to monitor one's diet. Nutritional information such as calories, total fat, saturated fat, vitamin content, etc. would be coded into a barcode and this would be placed on the packaging of all food products. People would scan the nutritional barcode, and enter in the approximate number of servings they are eating. I envision the device to be similar to the laser type things used to read regular barcodes at a supermarket. Data could be transferred to a computer via USB and people could compare what they have been eating to their recommended daily allowance, enabling them to monitor their dietary intake. I see this as being especially valuable to people with certain medical conditions.

       It seems to me that such databases must exist and that they can be queried using UPC.

       Very good for diabetics, people with gluten intolerance. Could be discreetly printed on menus in food outlets as well.   

       I have a barcode reader for programming some of my videos; it has an LCD display and it's not much larger than a big pen. Sounds like the same form factor.   

       Have a croisssant ..... <BEEP>.

       I thought I saw this before at the bakery, but it was just an annotation in another idea (see link). Good for you for formalizing it as an idea.

       It will need a database carrying more information than you can code into the barcode. The UPC barcode holds less than a dozen bytes. The scanned code will need to be just the database key, which links to the data carried in the reader.   

       This would be perfect for those with odd needs that are never included on the package: A dialysis patient needs to know the phosphorus content. Certain transplant patients must avoid grapefruit. Peanut-sensitive persons need to know not only whether the food contains peanuts, but even if it was processed with equipment that also processes peanuts. Most manufacturers don't want to add more labelling to food products, as it tends to cause customers to be alarmed.   

       Program it to select the data *you* are interested in. Point - *bleep* - customized labelling.

       Cuecat. Because this exists, there is hope for ALL half-baked ideas. Diet barcode could work great if you integrated it with a PDA and built in scanner. Could have a wireless link to an internet ready pc to access caloric/serving size databases.

       You mean like the Socketcom CF-card scanner or the Mitigo digital camera based scanners and the PocketPC?

       The product you have imagined exists! Check out http://www.bfitapp.com (the Website seems to load slowly, so be patient). I have not used it and don't know how many records the database has, but they definitely have the same idea.

       For this to be useful, i think your diet must consist of lots of prepackaged foods. (as opposed to say, fruits and vegetables)
