Additional field for a Food Diary

[timbatog]

I've a few users looking to keep a track of their food intake - there are many people whose health is impacted by IBS and other gastrointestinal related issues who need to track this over a long period to help identify trigger foods. Having this as a field to add the specifics food items and their meal/time of day this was consumed would be really really useful.

Is this something that could be easily and quickly added - perhaps even the ability to add a custom data field for other types of health data that need tracking?
