When dragon fruit or pitaya fruit first started appearing in the markets in India a few years ago, people were confused by its unusual shape, its weird-looking flesh and its exotic name. I remember at one point, it was also steeply priced at Rs 400 a fruit! This made a lot of shoppers look the other way. Today the exotic status of the fruit is waning along with its price, making it more affordable to Indian households. If you are planning on buying the dragon fruit, you should know about its health benefits.
Helps gut health: Are you always bloated? Then you need prebiotics, a plant fibre that nourishes and helps the growth of the good bacteria in the gut. In other words, they work as food for the good bacteria. Dragon fruit contains a carbohydrate known as oligosaccharide which works as prebiotics to improve your stomach health and digestion. 
Great for diabetics: Diabetic patients have to think twice before deciding which fruit to eat. Dragon fruit is a great option for those who are diabetic and crave fruits. Because not only can it help stabilise blood sugar levels, but also prevent sugar spikes . But that's not all; It reduces oxidative stress and cardiovascular complications in diabetic people. 
Restores energy balance: Our sedentary ways, poor lifestyle, bad high-fat diet disrupts the energy-balancing mechanism of our body, promoting obesity and other lifestyle diseases. A dragon fruit a day will help your body increase the energy intake without increasing your body weight. 
Fights cancer: Like tomato and watermelon, the pitaya fruit also contains rich reserves of lycopene. Lycopene, as we know it, is a compound that blocks the damage-causing free radicals. It is a known cancer-fighting agent, especially ovarian cancer.
