Two weeks ago, Oreo released a limited edition with a vanilla shell and a bright pink filling flavored like the marshmallow candy Peeps. And people who have tried them have noticed an interest side effect: the pink dye used in them turns your tongue, your spit—and your poo—a shade of pink.
One reviewer said, “My spit looks like Pepto-Bismol”, while another said that, “My roommate ate a whole pack of Oreo Peeps and left a pink stain in the toilet.”
While Oreo has yet to comment, USA Today previously reported that stuffing your face with foods heavy in dyes can produce “a greater spectrum in your rectal rainbow.”
