I've had similar idea with supermarket receipts about 10 years ago, but had trouble with implementation — OCR APIs were very enterprise-oriented and unreliable. However, instead of nutrition, I was thinking more into automatic recipes, and re-ordering online, getting feedback about the stuff you bought to build your taste profile and recommendations.

If you have good data of all the households purchases, you can do so much good stuff with it, the problem is getting this data reliably.

Good point! What would be most valuable to you from this data? Recipe suggestions could be one thing, but I guess most people build their shopping list from recipes. Re-ordering is probably something that retailers will try to make easy.
