Dragon fruit, also known as pitaya, is a tropical fruit that has gained popularity in recent years due to its unique appearance and health benefits. The fruit is native to Central and South America, but it is now widely cultivated in Asia, especially in Vietnam and Thailand.
In terms of nutrition, dragon fruit is low in calories and a good source of fiber, vitamin C, and antioxidants. It also contains small amounts of iron, calcium, and phosphorus. The antioxidants found in dragon fruit can help protect the body against oxidative stress and reduce the risk of chronic diseases such as cancer and heart disease.
