answer:Never played this, so I have no idea, but looking it up I believe the game has an inventory you bring up, and whatever snacks you’ve collected should be there. Some refill your health, while others refill your stamina. Here’s what I got on GameFAQ’s; ’‘When you find food resource that you have to load up in a rucksack by holding A, you can instead hold X to break it up, they usually break up into a couple snacks and a coffee or energy drink. The coffee and energy drink only remove stamina penalties caused from being tired. I don’t think any thing else refills your stamina other than snacks.’’ It would appear that some snacks refill stamina and not your health, and said snacks, like coffee or energy drinks or whatever, can only be used when your stamina drains enough. For replenishing health, I think it’s different things that do it, like pain killers. Either you guys didn’t come across any, or are not accessing the inventory. …more or less a wild guess here, though. :/
