Cap’n Crunch Berries Cereal: Oops All Green Poop (WTF!!!)

Let me preface this article by saying that I am a fan of Cap’n Crunch Berries: Oops All Berries

Learning About Crunch Berries & Green Poop…

Although I rarely eat cereal anymore, back in December 2012, I was grocery shopping with my cousin (who I lived with at the time) – and fiending for some cereal.  While browsing the cereal aisle, it didn’t take long for me to make a decision…

My pick was Cap’n Crunch Oops All Berries… Thereafter, my cousin cosigned my decision and snagged a box of Oops All Berries for himself.  Immediately after grabbing a box, my cousin was like, “Dude, you know those (Cap’n Crunch Berries) turn your poop green right?”  My reaction to this hilarious question was a chuckle… I assumed he was cracking a joke – mostly because the cereal is so damn colorful.

But dude was not playin. After hearing me laugh he says, “I’m serious dude – you will sh*t green”…  At this point I’m laughing even harder, nearly to the point of crying… I still thought he was joking around.  I called him out on the “joke” but he insisted that he wasn’t playin.

At this point I’m still laughing and am like WTF did you just say?!?! Haha.  I asked him how he knew that Cap’n Crunch Oops All Berries cause green sh*ts.  He explained that he had a highly reliable “source” for his information.

The source: His former co-worker.  Apparently while on shift (at a grocery store), his co-worker had to drop a deuce.  After examining this deuce, he reported back to his fellow co-workers that the deuce was discolored – it turned Hulk green.

This deuce report intrigued his co-workers, each of whom asked him what he ate.  The response: “Crunch Berries.”  Next, he and my cousin Googled the following “Crunch Berries” + “green poop”… and sure sh*t – they’d discover a myriad of anecdotes from others who experienced the green deuces after eating Crunch Berries.

My Experience: Crunch Berries Causes Green Poop

After listening to my cousin’s story and Googling “Crunch Berries and Green Poop” for myself, I believed that it was possible for some people to deuce nuclear radiation green from the colorful cereal.  That said, I assumed that the Hulk deuces only occurred in a small percentage of Crunch Berries consumers… Moreover, I didn’t think that Crunch Berries would cause me to light up the toilet with an absinthe steamer.

That said, I can verify that I had my own green deuce experience for the first time ever after consuming Crunch Berries cereal.

The first few times I had eaten Crunch Berries, I either:

  1. Never dropped a green deuce.
  2. Or… never looked at my deuce to notice it was green.

However, once my cousin suggested that I look out for the green deuce – I was on patrol.  On the day that I ate Crunch Berries cereal, I laid a healthy UPS brown deuce… Anyways, the next day I woke up and had to deuce.  I went to deuce, and I’ll be damned – the security deposit was an obvious Hulk green.

I was like WTF. Laughed some more, called the cousin to report the incident.  To make a long story short – I finally experienced the incredible hulk deuce thanks to Crunch Berries… and no I’m not going to provide evidence (nasty AF mane).

My GF: Skeptical of Green Poop from Crunch Berries

Fast-forward my life by 6-12 months and I’m out grocery shopping with my girlfriend who happens to like Crunch Berries cereal.  She grabs a box of Oops All Berries, I informed her that she would sh*t green… Her reaction was similar to my initial reaction (while cereal shopping with my cousin); she laughed and assumed I was joking.

She ate a bowl or two of Crunch Berries each day – and I continued asking whether it turned her sh*t green.  She reported no abnormal deuce coloring… and continued assuming that I was full of (green) sh*t with my claim that Crunch Berries cause green poop.  I told her that maybe she’s somehow immune to the green deuce effect…

Months would eventually pass and she mixed up her cereal lineup… No more Crunch Berries for a while.  Eventually she got around to buying another box of Crunch Berries.  As she eats a bowl, she jokingly asks: “Am I going to sh*t green?”  I responded with: “IDK. Maybe not.”

A couple days pass and… *drumroll*… she finally sh*ts green!!! Finally another believer in this (green) sh*t.  (Unfortunately there are still plenty of green poop skeptics out there).

Why Crunch Berries cereal might cause green poop

There are a few reasons that Cappy Crizzy Unch a.k.a. Crunch Berries might transform your poop from a dull Starbucks coffee brown to a glowing hue of superhuman green.  I suspect that the color change is attributable to the artificial coloring additives within the Crunch Berries cereal (common sense).

  • Artificial coloring – The artificial coloring additives within Crunch Berries cereal are the reason you end up with mint chocolate chip green stools.  I’m not sure if these are actually unhealthy, but personally, I’ve never experienced this color of green deuces from any other cereal (or food).
  • (Green) Food coloring – The primary reason that your poop turns green is because of the coloring in this cereal.  There are green berries – that might play a big role.  When it goes through your digestive system, it retains the coloring from eating this cereal.
  • Unhealthy – This isn’t really a reason, but the cereal is unhealthy.  Who knows if that colorization will one day be linked to some unknown disease or sickness.  I would think that eating Crunch Berries is safer than drinking paint (some people actually do this on the show My Strange Addiction – I wonder what color their sh*t is).

A more scientific answer to explain the Crunch Berries Green Poop

Food coloring. Experts suggest that when foods like Crunch Berries with a lot of artificial colorings are consumed, the food coloring (or dye) isn’t always fully absorbed by the intestines during digestion.  The dye that isn’t absorbed ends up seeping into food material that’s sitting in the gut, transforming it into a green color before the stool is passed.

A combination of the artificial colorings in the green, blue, purple, and red Crunch Berries eventually mix with each other – as well as with yellow-green bile fluid present in your intestine.  This intermixing then transforms food material in your gut to an unnatural shade of seafoam green, thereby causing you to drop a green deuce.

Despite the fact that green poop is abnormal, it’s not usually something to worry about if it was caused by artificial colorings in food.  Experts suggest that it’s probably not bad for your digestive health.  Nonetheless, some speculate that regularly consuming foods that are high in artificial colorings may be bad for your long-term health (increasing risk of certain diseases).

Are other foods besides Crunch Berries associated with green poop?

Yes. There are plenty of other foods that, when consumed, may cause you to poop green.  That said, it is unclear as to whether they will generate the same shade of parakeet green as Crunch Berries.  From a simple Google search, I was able to determine that both: artificially-colored foods and plant-based foods cause green stools.

  • Artificially-colored foods: If the right combination of artificial colors are present within the foods that you eat, you may end up deucing up some green.
    • “The Halloween Burger”: An example of another popular food item associated with green poop is “The Halloween Burger” at Burger King. (I’ve never tried this).  Apparently the Halloween Burger has dark charcoal black-colored buns as a result of a potent combination of coloring dyes.  I guess the yellow and blue dyes used in the dye combination weren’t easily absorbed into consumer’s intestines… resulting in a #greenpoop trend on Twitter.
  • Plant foods (chlorophyll): Not all green deuces are from artificial additives… green poop can result from consuming high amounts of chlorophyll-rich greens such as: kale and spinach.  In case you didn’t know, chlorophyll is the green pigment in plants that allows them to absorb sunlight for energy.  That said, I guess it takes a lot of chlorophyll to deuce green from plant consumption – so maybe vegans and/or vegetarians would be more likely than others to experience this.

For all the skeptics of “green poop” from Crunch Berries

If you remain a “green poop” skeptic, perhaps you should try a self-experiment.  Order a few boxes of Crunch Berries and eat as much of the cereal as you can in one day…  There’s a good chance that if you only eat Crunch Berries, your intestines won’t be able to absorb all of the dye and you’ll end up with the extra lit, absinthe colored Cleveland steamers.

    1. Order Cap’n Crunch: Oops All Berries: Order some Crunch Berries on Amazon or go to Wal-Mart and buy a few boxes.
    2. Chow down Crunch Berries: To increase your chances of a green steamer, you’ll want to eat as many Crunch Berries as possible… eating a just a small bowl may not get you the green hue poo (or the particular green glow that you were hoping for)…  The quantity of Crunch Berries that you eat definitely matters. (Lower quantity consumed = lower chances of green deuce).
    3. Wait for a bowel movement: Tick, tock, tick, tock…
    4. Observe the outcome (pls, no pics): Examine whether your deuce color transformed from the Crunch Berries.
    5. Report back here to the comments section: Mention whether your deuce acquired dat glow.

Final note: If (for whatever reason) you want your poop to glow like Flubber, then eat Crunch Berries Cereal – it’ll do the trick.

    Family picked up this cereal a few days ago and I’ve been devouring it since. Lo and behold, I went to poop this morning and was like “WTF is my poop green???” then I remembered reading an article about this cereal turning your poop green awhile back and it all made sense. LOL.

  • Mallory Aug 27, 2018 @ 15:12

    Completely got this cereal on a random chance. Never even had crunch cereal before. I was a weird kid for not having this brand before. Not only did this cereal destroy the insides of my mouth but destroyed my bootyhole too!

    What the hell man! This is suppose to be the most important meal of the day! Not some science experiment on my bowel movements. Somewhat salty.

  • Isabel Aug 25, 2018 @ 16:57

    I ate a jumbo box of oops all berries cereal in less than a week and I’m still pooping green and I googled it. 😂😂😂

  • Ty Aug 22, 2018 @ 6:40

    LMAO. My stove and oven broke so I’ve only been chowing down on MF Crunch Berries. Thought I was gonna die with how vivid green that shot was. Glad it’s normal.

  • Logan May 31, 2018 @ 15:39

    This just happened to me and was all “WTF did I eat?!?”

    After a minute thinking about it I remembered yesterday I was snacking on dry Oops all berries and realized it just had to be from all the dyes in that.

    One google search and this is the top result. lol.


  • Trenice May 28, 2018 @ 11:41

    I feel victim to the Captain so here I am doing the big google search to see WTF. Well I’m a believer. I was like ohhhh my cheat day was full of karma. Haha. I thought my body was trying to kill me for cheating.

  • Danny May 20, 2018 @ 4:17

    Oh man I’m so happy I found this conversation, bro I’ve been eating crunch berries since a kid (I’m 25) and I’ve always had crazy discolored bowel movements after eating said cereal. Thank god I’m not alone on this.

  • Jarronimo May 14, 2018 @ 17:17

    Yes it’s true, it took me a while to figure out it was the Oops All Berries Cap’n Crunch cereal that was turning my stool green.

    I thought it was the coffee I was drinking at first, but then I realized it was the cereal when it was all I have eaten one morning.

    I thought I was tripping.

  • Jade Apr 22, 2018 @ 15:03

    Glad I’m not the only one! On a drunken night I came home and devoured 2 huge bowls of oops all berries and the next morning I was in for such a shock!

    I thought I had gotten bad beer and my husband reminded me of the 2 huge bowls of cereal so I googled and found this hilarious article about everyone else having the same issue!

  • Logan Apr 10, 2018 @ 3:51

    The greenest green. I’ve been eating a bulk bag of crunch berries for a week now and I couldn’t figure it out. I thought it was a bike problem. My boyfriend literally kept mentioning the black bun thing from BK so you vindicated him and made him smile and Solved the Mystery! Thanks!

  • Haydingus Apr 2, 2018 @ 2:05

    THIS IS SO FUNNY. I literally just ate like four bowls of this cereal last night while I was drunk. I had the typical hangover shits and to my surprise, my turds were TEAL. Not green, but TEAL. I was baffled and I quickly searched google because I was convinced my internal organs were fucked until remembering I ate four bowls of that shit. It’s such an experience.

  • Monica X Mar 15, 2018 @ 12:34

    My 8 year old daughter and I love oops all berries. She had shown me a few of her crazy green poops. At first I thought she was sick, but then I saw one come from me! That’s when I started to suspect the cereal.

    In doing a quick Google search, I found your website and very funny article about your experience with the green poo. Nice to know I’m not crazy and that my daughter isn’t sick!!
