It will be good to know if we could get a hold of their data - this is a fascinating experiment.

While you are waiting, I just googled around and found this - http://kasabi.com/dataset/foodista - Haven't looked into it to see if it has much though :-/

please do, I would be really interested in using this dataset for a project

Its a good data set. I have been running it against the USDA food data for a new project I am working on. Let me know what they say and I might be able to provide it to you in a more workable format.
