First, the absolute best news: paper is mostly cellulose. Cellulose is just plant fiber. It’s the same stuff in celery and lettuce, except paper has been pulped, bleached, and flattened into sheets.
Your digestive system treats that pinch of paper like a rude guest at a party. It looks at it, says “Nope, not on my list,” and shoves it right through. You won’t digest it. You won’t absorb it. It will simply... pass on through, usually within 24 hours.
Think of it like eating a single popcorn kernel that didn't pop. It’s a weird little lump that takes a ride through the digestive waterslide and comes out the other end. No harm, no foul.
But What About the Funky Ink and Gloss?
Ah, here’s where we get a little more thoughtful. A plain sheet of notebook paper? Mostly fine in a pinch. But that glossy magazine page with the bright perfume ads? Or the receipt from the gas station? That’s a different story.
Inks can contain heavy metals like lead or chemicals like BPA (which you might know from plastic bottles). Glossy coatings are often made with clay or plastic resins that are a bit rougher on your gut.
Eating a tiny lick of a receipt won’t send you to the hospital. But if you’re a compulsive paper-eater, chomping on glossy stuff daily is like asking your body to play a game of chemical roulette. Not fun, and not worth it.
