Here’s the real issue: Peanut shells aren’t exactly clean. They grow in the dirt. They get washed, sure, but they also get all the fun stuff—pesticides, dust, and whatever was on the factory floor.
Plus, they’re sharp. Think about it. You’re chewing on splinters. A big chunk can scratch your throat or, worse, your insides on the way out. Fun, right?
Moral of the story? If you swallow a piece on accident, don’t panic. You’ll probably just pass a fascinating, crunchy poop. But making it a habit? That’s a terrible idea.
What About Roasted Shells?
You see those fancy roasted peanuts in the shell at the store. They look appetizing. Some people even fry them. Does cooking fix the problem?
