Does dragon fruit make your bowels black?

I have been eating the red variety of dragon fruit for the past week, and have noticed that my poop have been getting darker in color, in fact its black now. I have not felt anything wrong with my tummy to warrant bloody poop, and my guess is that the dark red coloration of the dragon fruit is the cause.

Does dragon fruit make your bowels black?
I'm unsure of any corralation between eating dragon fruit and black stool. What I do know for sure, is that blood in the stool, without pain, is often the first presenting sign of colon cancer. The test used to detect the presence of blood in stool is called a 'guaiac test'. It is both simple and painless and only requires a very small amount of stool be put on a card that is treated with enzymes. Then a few drops of liquid are used to wet the area and the results are obtained by a color change.



Forget about eating dragon fruit for a couple of days (it shouldn't take any longer than that to get out of your intestines). Then, if your BMs don't return to a normal color GET YOURSELF TO A DOCTOR'S OFFICE!
Reply:stop eating it for a week and see if your poop goes back to normal... then go back on it for a week and see what happens.. if it goes black again then yes it the dragon fruit.
Reply:Most likely you are right.
Reply:I can find NO evidence that eating dragon fruit makes the stool darker in color.. I believe that this fruit contains nitric chemicals (which are good) and it is possible that they cause the stool to turn black...



I used to eat this fruit ALLLLLLLLLLL the time when I was in Asia.. I loved the fruit.. do not know why as it had no taste to speak of.



In all likelihood, the dragon fruit is causing your stool to be darkened but that certainly is not posing any health risks by doing so.
Reply:Why, yes it does. I've been eating dragon fruit for 3 weeks now and if "black is beautiful" like they say, then I just crapped a masterpiece.
