From what I understand, in previous versions you could consume food to heal. This was not a well received concept, and was gotten rid of in the most recent patch. For which I am thankful. I don't want food used as healing potions either. They just need to do some tweaking on the current camp supplies system to balance it out better. Just my opinion.
Stealth works pretty good right now actually, although rogue sneak attacks are kinda broken. You just need some practice with it to get the hang of it. There is a button you can push to see enemy sight cones, which let's you know spots you can enter stealth even in combat mode. I have mine mapped to left shift, but I can't remember what the default button is. Just check your keybind settings. Also when you move the cursor around it has different symbols on the cursor itself to indicate shadow levels, which effects your ability to successfully stealth if you enter somethings sight range.
Have a great day !
