Which .json file do I edit to make fridges have less food?

I’ve been trying to lower the spawn rate of food in cities, break rooms, etc. by editing the .json files but I can’t seem to find the right one. I’ve tried fridges.json in the SUS folder, and the fridges section in collections_domestic.json. I don’t seem to be having any effect in-game, fridges are still loaded with food unless I’m not doing something right. I can’t see any other itemgroups to edit. Am I doing something wrong here? I am totally new to json editing and any help would be greatly appreciated. Thanks.

There is the fantastic No Hope mod doing exactly this. You may want to check out what said mod changes.

if your just trying to lower the spawn rate of items you can do it settings to and set it to like 0.5 or something
