The  dragon fruit is less commonly referred to as The Pitaya.

Dragon fruits contain around 60 calories each and are rich in vitamin C, B1, B2 and B3, and minerals such as iron, calcium, and phosphorus. 

Eat dragon fruit as a good natural source of anti-oxidants which help to prevent the dangers of free radicals which can cause cancer and other undesirable health detriments. The number, quantity, and variety of antioxidants in real foods like dragon fruit is completely unmatched by any food supplement or pills - even those claiming to have 'antioxidant' health benefits.
