feeding upgrade uses regular food regularly, but does not use Endless Ham when it is in a backpack. also, Endless Ham cannot be placed in the inventory of the feeding upgrade filter.

Only food items can be put in feeding upgrade, adding compatibility for normal items is not possible/possible but with way too much work
