If we really have to collect and manage food items, they should use Rations..
+1 There is no point to having different types of food in the current camping system.
- We can no longer eat food to regain food, which means that having different food that regains different amount of hp is worthless. This is good; please don't bring back eating during combat
- Different foods don't give different effects during long rest. It'd be interesting if the most common food used gave slightly different bonuses. Though i'm not sure this benefit would be worth the hassle of inventory managing the different food types. A better solution is to just use rations, but allow cooking of different meals for different benefits.
