First let's get the specifics out of the way. This is not some fictional piece on a weird dystopian, post apocalyptic scenario (although it could be. And hey, weirder shit has happened in the movies).

Basically, you know how when you eat pineapple, the inside of your mouth feels like you just swallowed a cactus? Or worse.

So, we did a little digging and we found there's actually a solid scientific reason behind this.

So the deal is, that pineapples are a source of the enzyme Bromelain. Correction: pineapples are the only natural source of Bromelain.

Now, Bromelain is an enzyme that breaks down protein. What that means is essentially, when you're eating a pineapple, it's eating you!

Apparently, if it's given enough time, it can eat away at a human tongue.

I know what you're thinking. When I first read that, I had visions of that little piece of pineapple burning a hole right through my body. Just like the Tesseract in Captain America.

But of course, this only works in the mouth. We have the stomach acids to thank for that.

So yes, we just thought we'd let you know about the fruit that takes a bite out of you, every time you take a bite out of it.
