I'm interested in data on people's eating habits. Ideally this would be a "food journal" type of thing that has data from individuals showing what they ate at what times/days. Ideally it also would include information like whether they were eating at home or at a restaurant. As always, I'm interested in data at as fine a level of granularity as possible, so I'd prefer a dataset of individual records of individual people's individual meals/snacks rather than aggregated data showing how much people in some group ate on average.
Any ideas on where I can obtain such data?
