The pitahaya (pronounce like pee-tie-ah-yah)  looks much like a yellow grenade, and even acts like a grenade! An intestinal grenade, that  is! While its gray-white almost transparent flesh,  full of  circular black seeds,  is quite delicious, most people will spend the next day or two in the posture of Rodin’s Thinker after eating one of these. For this reason, the pitahaya isn’t a popular snack among Colombians, except when their need to “cleanse” themselves.

Recently they began exporting this fruit to the USA. I hope it’s sold there with a warning label!
