The game adds a new level of complexity to food that we don't have in other games.
Neither you as the player, nor your villagers actually need food to survive.
Soldiers will stop following commands and abandon you if they have no food.
But the point, is that instead of having a potions system, the game integrates potions and food into one thing.
That is cool and all, but it makes it a lot more complicated to manage food production and consumption.
Right now, I can choose what I eat (As long as I have it ), but there is no direct way for me to choose what my villagers will eat.
I have seen this stats:
Nutrition Duration - How long till hunger comes back.
Health - the food adds points to the health bar.
Health regeneration - How fast health will regenerate.
Stamina - Adds point to the stamina bar.
Stamina Regen - How fast stamina regenerates.
Productivity - How much more will be produced
Skill XP gain - How fast will I or the NPC level up.
Combat Attributes - Increases the combat attributes.
Hunger speed - A negative value to decrease the hunger.
Now try to manage all that and consider what profession should eat what.
The woodcutters go outside the village and need health and stamina.
Even if I had granular control over what they eat the decisions are not easy.
