The only RED Dragon Fruit (aka pitaya or pitahaya or strawberry pear) that I am used to were those with RED SKIN and WHITE FLESH (Hylocereus undatus). It tasted a bit bitter to me and I didn’t like the after-taste. Other reports said it tastes like a mix of kiwi fruit and watermelon.
I didn’t take notice of it other than eating what was being served to me until a friend shared about its benefits and salad recipe. As it is beneficial to health, I posted it here under “Why Dragon Fruit?“. Only then did I notice that there is a RED SKIN Dragon Fruit with RED FLESH (Hylocereus polyrhizus) variation.
Now I also found out that there is YELLOW SKIN variety (Selenicereus megalanthus) and with only white flesh.
The taste of the red flesh variety is sweeter and the after taste is great to me. Other reports said it tastes like raspberries. I will usually eat 1 whole fruit (about 300-500gm) willingly which I normally won’t with other fruits. However, it is not that common as they are in Malaysia.
Yesterday, at a neighborhood market, I saw red Dragon fruit selling at a stall and as usual, only white flesh variety was on sale at S$1.50 (approx. US$1) per fruit. When asked, the seller said that white flesh variety is preferred by most consumers because those who consumed are paranoid about the reddish variation of urine or stools that they will pass out after consumption. They are apparently worried that the red flesh is a result of genetic modification, adding of artificial coloring or preservatives, etc.
This red “symptom” happened only if one eats quite a bit, a fruit or so as I have experienced myself.
Exporters in Malaysia for pitaya explained that the color is 100% natural and that it is not genetically modified or dyed red. The color comes from natural pigments known as hylocerenin and isohylocerenin and is also known to have natural florescent property. That makes the red flesh variety prettier when served.
If one were to eat a lot of blackberries or those fruits with such pigmentation, the output into the toilet bowl will be similar. However, how many people eat 0.5kg or more of such berries?
Yet, red flesh variety is more expensive and they are sold here in kilogram (S$4-S$5 per kg) instead of by quantity. I recently bought 2 red flesh fruits for close to S$4.00 (approx US$2.80).
Malaysian exporters justified the higher cost to its benefits. One reported that “Eating red-fleshed pitaya fruit was reported to increase bone density, prevent colon cancer and ease constipation. This can explained why red pitaya cost more expensive as compared to white pitaya“.
It was also reported that the red flesh variety is believed to be rich in antioxidants and has an exceptionally high content of soluble fiber. It is considered a good source of vitamin C and its vitamin C is more easily absorbed than vitamin C from a pill supplement. Some bloggers swear that it helps to lower blood glucose levels in type 2 diabetes.
Well, anyone out there got a health benefit comparison report between the red and white flesh? Ahh, don’t forget the yellow skin.
Meanwhile, I will still go for the Red Flesh Red Dragon Fruit whenever possible.

I got hooked on to eating the red version of the dragon fruit after being introduced to it by a friend a couple of months ago. I eat about 1 whole fruit each day. However I find that my bowel movements have changed drastically, not only my stools are red but I visit the toiled after every meal. This has been bothering me but I cant stay away from the fruit. I was so glad to read about your comments, especially about the red colour of the stools and urine. Yet I am still a bit apprehensive about the fruit though I cant stop eating it. Any comments to add. Thank you.

I wonder if any scientific research has been conducted on the health benefits of the Red Dragon Fruit? I’m a big fan but has recently been worried about its genetic status. Your article does help reassure me a bit but at this point, I’m going to do the Red Dragon Fruit with moderation, applying the golden rule “Moderation is key”!
Thanks for the info.

I have tasted the red skinned white flesh dragon fruit and to me it is better to mix it in a salad. Can anyone send me a detailed information on how to plant and grow the Dragon fruit. Thank You !

I haven’t tasted the purple-fleshed dragon fruit yet. But your right the white-fleshed one isn’t that tasty. Looking forward to trying the purple thing. Anyone interested in importing dragon fruits? Im from the Philippines, and my family plans to start a dragon fruit plantation. We’ll plant red and white-fleshed variants, and possibly we’ll include the yellow-skinned one. If anyone’s interested you can reach me at doradexplorer_101@yahoo.com

the red pigment passing out during defecation is often known as Pseudohematuria, a harmless reddish discoloration in urine and faeces. i eat red dragon fruit everyday. sometimes i cut it into pieces but most oftenly i blend it into juice by adding little bit of water just to ensure it is not too muddy. I never added sugar because the fruit already has its own natural sweetness. If you guys thinking of trying this recipe please make sure don’t blend it for too long.

Glad to hear you guys like red dragon fruit so much. I love it too and take a fruit a day. I like to blend it as it make a very nice refreshing drink and the seed is broken up to ease absorbtion of it anti oxidant.
Guys, try organic dragon fruit. check out http://www.kenkorealorganic.com.

I love red dragon fruit and while my stools do appear to have the red pigment several hours after eating, the benefits of this fruit outweighs the colour. Dark pigmented fruits and vegetables have strong anti-cancer properties and since it is also rumoured to bring down the blood sugar levels in type 2 diabetes (which I suffer from), I eat red dragon fruit as often as I can. I recommend it to anyone who wants a good, natural antioxidant… Be healthy.. eat more red dragonfruit.
