First, the good news: paper is not poison. Most paper is made from wood pulp, which is essentially cellulose—the same tough fiber found in celery and broccoli stalks.
Your stomach, however, is a bit confused. It doesn’t have the enzymes to break down cellulose like a cow or a termite does. So, that paper square you swallowed will basically pass through your digestive system mostly intact, acting a lot like roughage.
Think of it as unexpected dietary fiber. In tiny amounts, it’s harmless. Your body will simply wave it goodbye in about 12 to 48 hours, none the worse for wear.
When “Snack” Becomes a Problem
Let’s be real: eating a single corner of a sticky note because you’re anxious is very different from eating the Sunday newspaper. The key is quantity and frequency.
Consuming large amounts of paper can create a bezoar—a dense, indigestible mass in your stomach. That’s a medical situation involving blockages, discomfort, and a very awkward conversation with your doctor.
There’s also the matter of additives. Glossy magazines, colored flyers, and receipt paper are not your friends. They often contain bleach, inks, and BPA (an industrial chemical) that aren’t meant for internal consumption.
