You can select "Copy" to duplicate food as you bring food to the table, or "Move" to actually reduce inventory, which can be used to simulate real-life situation in food consumption/replenishment. You can print out a list of food content when the inventory is full. Once near depletion, print out another list or simply compare with the on-screen inventory, cross out names of the remaining inventory on your originally list and you have a shopping list to go to the market with.
Tip: If you want to make your inventory control more accurate,
remaining portion(s) of a food called out form the
storage should be put back for future consumption.
(For example: if you dragged an apple out to the table,
but only ate half of it, be sure to put one half back
