Editor's note: here's the short answer -- blue food coloring turns your poop green. Keep reading to find out more, and then peruse the many, many comments for corroboration.

Since my freshman year in college (a small liberal arts college in
northern Vermont), I've been fascinated with the correlation between the ingestion of
food-coloring and the color of the poop produced. Lest you think I'm fabricating, here's the background:

The year was 1996. I was a biochem major at St. Michael's College in Winooski, Vermont.
I had consumed copious quantities of Purplesaurus Rex
Kool-aid in a one night time frame. A few hours later, I pooped. It was
green. Bright green. I was fascinated, and called as many of my
floor-mates as would come into the stall to marvel at the miracle of the
"not brown, not bloody shit".












I was a bit of a celeb for a while, until others replicated my
"experiment". Similar results ensued, with me being notified of each event
via e-mail. So, a craze started.

As the progenitor of the new species of poo, I was caught in the middle. Research spread far and wide; of
a campus of 2700 students, I was receiving up to 45 e-mails a day from
poopexplorers.

Anyway, enough drivel. Here's the science:

The dye used in purplesaurus Rex is FDA Blue #5, and dye-lake
red. Turns out that when metabolized in sufficient quantity, the blue dye combines
with bile, and forms a brilliant green. The red, absorbing at a 595nm
spectrum, is harmlessly eliminated.

What matters is quantity. I consumed 6
liters of the Kool-aid in the night in question (sans alcohol, that comes
later). I set up a study in the dorm, with people consuming anywhere from
(1) 250mL glass of the stuff (approximately (1) 8oz glass) to the maximum tested
so far, 6L. The experiment was structured on a single-blind study (won't get FDA
approval, but sufficient), with only myself knowing what each was consuming.

How did the experiment come into being, you might ask? Well, I campaigned for 24 "volunteers"
(the first consuming 1 glass, the last consuming 24 glasses). How did they
not know what they were drinking? Well, since it was only single-blind,
they essentially did -- though all were required to drink 6L of fluid total,
and ordered not to defecate at all in the 6 hours of the experiment.

Example: Subject 1 received 250mL of the subjected test substance, and
5.75L of water. Subject 2 received 500mL of the stuff and 5.5L of water.

Everyone was agreeable at first, but soon dissention reigned prime. But order
was maintained. After 6 hours, orders were given to poop, supervised (more or less).
Since I had unrestricted access to the chem and bio labs, samples of each
"extrusion" were taken, in the amount of 2g.

The results were heartening. I plan on getting a PhD (which, in this instance would probably mean, "PUSH
HARDER, DUMMY!") on this someday, so I won't post my final data, just enough
to give an idea:


  • Subject 1: 250mL Purplesaurus Rex with 5750mL water:

    Stool, firm and brown. Spectrophotometer reading: normal.

  • Subject 12: 3000mL Purplesaurus Rex with 3000mL water:

    Stool, firm(ish) and green(ish). Spec reading 550nm (definitely Green...just not GREEN)
  • Subject 24: 6000mL Purplesaurus Rex with 0mL water:

    Stool, Firm(ish) and
    Green, resplendent of original test subject (me). Spec reading, 535nm. Definition of GREEN confirmed.

  • Further experiments considered fruit punch (mostly synthetic, only 2.5%
    fruit juice), Hi-C of various persuasions, and various and sundry other
    store-bought concoctions.

    If you're interested in my results, let me know...I'll gladly share them for
    the good of society.

    dear poopreport,

    i know you may find this hard to believe, but you just eased my mind tremendously about our daughter's "poop situation." beginning yesterday about 5p.m. our daughter began having bright green dirty diapers. she has had four in a 24 hour period and i (being an over paranoid mom) have contacted everyone i know, including our pediatrician, and no one had any answers other than it will probably go away. that response just does not cut it with me. i had to have answers. i have been on-line non-stop trying to dig up a possible answer. i told our doctor that the only new food or drink she had consumed was "purple kool-aid" and lots of it. he told me that purple kool aid would not produce green stool. after reading your article i realize it can. thank you soooo much. after hours of searching and worrying, i am off to bed.

    -- grateful mom

    I saw an opportunity yesterday: at a bake sale I bought two cupcakes, one with thick green frosting, one with blue; ate them both as dessert for lunch. I was sure there was not enough food coloring to give me a real green poop, and I was right. However, the resulting movements were not brown--sort of a tinted gray with a hint of dull green. Some day . . .

    mandy m.'s picture

    I too had this problem of green poop. St. Patty's day green poo! for 2 whole poops. anyway, i had only 1 serving of Welch's grape juice and I also had only 6 peices of steamed asparagus the day before. So, who knows. i did not consume a lot of water. so maybe that helps your experiment. because it was very very green and very little grape juice consumed.

    Anthony L.'s picture

    Dave J your study was incredible. Today, I too, had a poop greener than ANY green I've ever seen in my LIFE! Like the others posting here, I was freaked, Googled it, and now I'm home free! MORE GENERIC "GRAPE DRINK" FROM CUB FOODS COMING RIGHT UP!

    I've had bright green stool for the past week- I just can't resist the slushies from my (northern vermont) convenience store. They usually consist of blue raspberry. You can literally see the poo dye the water in the toilet bowl- it looks like when you drop a bit of green food dye in a cup of water.

    Well, to add to the fun blue powerade will do it every time. Also, if any breastfeeding moms eat fruitloops they will turn breastmilk red...I didn't know this and kinda freaked the first time it happened...I thought the babies mouth or my breast was bleeding. lol.

    As a result of a heavy stomachache, and appendicitis kind of pains, I was suggested by doctors to drink Gatorade.
    I bought a 6 pack of "purple rain" flavour (grape - colorant: dark blue).

    My poop turned out to be "leaf green".
    Thanks for your web site, I thought I was becoming an alien!

    I just changed my daughter's diaper and about fell over. It looks as if somebody had dipped her little dooty in green paint (as green as grass). I instantly recalled what her face looked like last night after eating one kid's size scoop of Baskin Robbins Blueberry Sherbert/Blue Raspberry Sorbet...very blue. Oddly enough her stools turned green, wow! Can't wait to show her mommy what a great poo she had. It even stained her ass green! I wish I could post a picture for all to see (oooh gross, I know).

    Almost

    A few years back I was working on a mansion in Marin county. After 5 hours of intense wrangling over the second phase of a multi-million dollar contract, one of the lawyers, Eustace, stepped out. With a sour look on his face he sat on the tail gate of the electricians truck and let out a series of heavy rippers. At just under 300 lbs. he had that truck rocking with each one. I'm sure he would have blown the negotiations sky high.

    i have experienced multi-coloured poo... it was awesome. i was originally eating licorice, and found purple nestle quick (wild-berry flavour, yummy, but never found it in the shops again)and started eating spoonfuls of it. that afternoon i had a half green half purple poo... it was sooo cool, but i didnt deem it appropriate to take a picture. sorry.

    THANKS!!!
    I was just trying to figure out why my daughter's poop was so bright green! I was so worried. And here I am, reading your page!! She hasn't had any purple-colored drink, but she ate quite a lot of "cotton candy" ice-cream the other day, which was a brilliant blue color. I'm guessing that is the culprit.
    Oh, and by the way, once I drank several liters of fruit punch flavored Gatorade and the next day my poop (yes...sometimes girls do poop) was bright red. It really freaked me out at first until I realized it was from the Gatorade.
    Thanks for the informative page!! You've eased my Mommy mind tremendously!!

    In a little less then six years this thread has managed to garner over 1000 replies of "OMG me too" or "Thank God my kid isn't gonna die." That means about one comment every two days. To put this in perspective, think about only the group of commenter's who are trying to make sense of their kids off color poo.

    Each year about 6 million children are born to english speaking parents. Lets say a tenth of them (600,000) one day see green stool coming out of their little kids butt. Of that group suppose one in twenty (30,000) are so frantic that they call the doctor but can't wait for an answer so they google: "Why does my kid have green poop?"

    Now, of this supposed 30,000 it is evident that a few are desperate enough to read past the first three search engine hits and still click the link to this thread. From the original pool of 6 million what's left are a hard core group of parents with a pathological obsession over their children's health. Year after year.

    Trying to keep this thread off topic would be a sisyphian task of epic preportions.
