If you’ve had one of these Marshmallow Peeps Oreos, you may have experienced this very interesting side effect in eating it. In an article from Cnet, the side effects are seen on your tongue, and kind of grossly, in the toilet.
This delicious treat causes your tongue super pink and your poop pink as well. Oreo’s parent company, Mondelēz International says that “this is common with brightly colored products such as ice pops, gelatins and drink mixes, as well as with certain fruits and vegetables, including beets and cranberries.”
So just be mindful, if you experience any of these “symptoms”, don’t fear, it’s only temporary.
