I am pretty sure I have seen an app that does food recognition already. Not sure if it was for iPhone, or traditional desktop. The one sad aspect of this idea is that in theory, humans should be able to determine their needs without external monitoring devices - certainly when it comes to food. Perhaps instead of an external device, it would be better to invest in some self awareness? I realize, though, that it is not possible for everybody, in fact, I also don't know a good way to learn it.
