I already took some things out before taking the pictures but you have a rough idea that this needed to be dealt with. First I decided to line the shelves with a plastic liner intended for kitchen cabinets. I purchased mine in IKEA.
Then I divided my food into groups and decided which shelf to place them on. I have shelves that contain: kitchen appliances
Then I have the "baking shelf"
the "sweet tooth" pull out shelf
container shelf with pasta and rice and similar products
and finally the can and bottles shelf.
I still have one shelf open right now for any future need.
This was fun!
