What happens when you eat expired pudding?

Depends on how long it has been expired for. If it has only been a few days to a week, it's likely nothing will happen. If it has been expired for a month or more, you'll probably get food poisoning, so you should get medical attention if that happened.

It all depends on the person. Sometimes nothing at all happens to the person, but sometimes people may experience upset stomachs followed by vomiting and diarrhea. It is never a good idea to eat expired items, but those are some possible side effects.<br>

Yes, it also depends on how long the item was expired.
