Tonight, I finally got around to looking into why food stats weren't adding to actual stats (shown in #showstats).  It turns out that all of the code to calculate food was already there, but the code for calculating item bonuses wasn't allowing food/drink to work.
In bonuses.cpp around line 182, after this:
	Code:
		if (!inst->IsEquipable(GetBaseRace(),GetClass()))
	{
 Add this line:
	Code:
			if ((!inst->GetItem()->ItemType == ItemTypeFood) && (!inst->GetItem()->ItemType == ItemTypeFood))
 
And that whole IF should look like this when you are done adding it:
	Code:
		if (!inst->IsEquipable(GetBaseRace(),GetClass()))
	{
		if ((!inst->GetItem()->ItemType == ItemTypeFood) && (!inst->GetItem()->ItemType == ItemTypeFood))
			return;
	}
 If anyone has any issues with this or thinks it may cause a problem or open possible exploits, let me know.  I can't think of any.  Also, if someone knows of a better way to write it that might be easier on the CPU, feel free to post it.  Otherwise, I will get this added to SVN very soon.  And, just in time for Thanksgiving too *WINK*
