Food spoilage, vomiting its the same thing. You are eating food that might be spoiled, you don't really know. I typically have 5 stacks of meat and loads of canned food, stuff I grew, enough food to feed 20 people for a month, without iron gut perk which lowers metabolism, without ANY cooking perks, and I never buy any food ever. WE're finally getting it to the point where you might have a small struggle with food on the first couple of days probably. Its a good change IMO.
Read all the requests for food spoilage and a reason to horde food or even buy it. Finally I'm buying some food or doing buried treasure quests to get food, and a player SHOULD freak out and hunt every animal he sees not pass them by because you have 5 stacks of meat and a full chest of food stocked up without even trying.
