Dragon fruit is native to Central America, but also developed and exported from several countries of Southeast Asia, such as Thailand and Vietnam. Hylocereus undatus, the Latin of dragon fruit, is a low-calorie fruit but offers a lot of nutrients including vitamin B and C, phosphorus, protein, calcium, fiber, captin, and antioxidants.
I have never seen this fruit in real life nor tasted it, so it is very difficult for me to know its taste, however from the picture it is looking quite great.
Let's appreciate nature for this wonderful fruit.
