From the cactus family, specifically the genus Hylocereus or sweet pitayas, dragonfruit is football-shaped and has a leathery, leafy skin that is deep red or pink in color. It comes in three varieties, red flesh, white flesh and yellow flesh, all of which are embedded with hundreds of black seeds and have a mild, sweet taste. The best-tasting variety is the one with red flesh, which is succulent when eaten.
One dragonfruit can weigh between 150 and 600g, but with its thick covering, only about 60 percent is edible. To enjoy dragonfruits, it is best to eat the creamy pulp cold. The middle part is the sweetest, and after cutting the fruits in half, you just have to spoon the flesh out. Dragonfruits are common in Asia (particularly in Taiwan, Vietnam, Thailand and the Philippines) and in Central and South America. They are among the many wonder fruits that are said to provide multiple health benefits. In addition, dragonfruits help protect the environment because they absorb carbon dioxide at nighttime, and then release oxygen to purify the air.
If you are looking for fruits that are filling and delicious, but will help keep your weight in check, dragonfruits are a perfect choice.
