Old food tables: Finish, or replace?

I've already tried looking through the itemdb for an patterns, but there seems to be no correspondence between any items that provide the same stats.

I wish it were determined by ID; it would make the job a LOT easier.

If it were based on ID number, it might be easier to figure out, but it would be very hard to share what we know via the wiki since we're back to not discussing mods/data mining.
