This mod displays what food and healing items have what hunger, health, sanity values (including rotting).
It will work for items in inventory, backpack or in containers.
You can use ALT button (force inspect) or button 'Y' if you use controller to see how many days there are left until food spoils.
WARNING:
For now only host can see the values of food. I'm trying to fix it.
Mod in development, bugs expected.
