Which Foods Are Most Demanded?

Description

The following plot shows the total amount of cases of each food demanded, totalled from 2005 to 2014.

Using cases as a measure of demand is problematic, as (for example), a case of peanut butter likely does not have the same cost, nor value to the recipient as a case of popcorn.
As an overall measure of the level of demand of each food it is reasonable.
Should a dollar figure for each food item be made available, the analysis could be redone on a dollar basis.
