There was a hackathon this weekend at EPFL, Switzerland and some of the teams were working on this dataset. Quite a few interesting hacks came out of it. A few interesting ones were : * an app to check for allergens * an app which lets you know what are the "healthy" recipes you can make using a particular product * an app which lets you take a photo of a restaurant menu (ANY restaurant menu !!), and then uses the openfood dataset (along with a few other openly available dataset) to give you a health footprint of all the food items !! I would say datasets like these are pretty rad !! Its painful to collect them in one place thats why there are not plenty of them around.... !!
