I'm working on an app (Bitesnap) to help people keep track of their diet. At some point we'd like to add more features to help users figure out what's causing their dietary issues.
I'm using a simple Excel worksheet to record everything and once a month I move the data to an SQL Server table for easier correlations.
BTW, make sure you also give the ability to record beverages because in many cases they're the root of stomach problems. And you could add some social functionality so users could correlate with others who have similar dietary habits.
