Hylocereus megalanthus (Yellow Pitaya) has yellow-skinned fruit with white flesh
The fruit weighted is from 150-600 grams and the flesh, which is eaten raw, is mildly sweet and low in calories. Eating the fruit is sometimes likened to that of the kiwifruit due to a prevalence of sesame seed-sized black crunchy seeds found in the flesh of both fruits which make for a similar texture upon consumption. The skin is not eaten. The fruit may be converted into juice or wine; the flowers can be eaten or steeped as tea. Although the tiny pitaya seeds are eaten with the flesh, the seeds are indigestible. It is generally recommended that dragon fruit be eaten chilled, for improved flavor. Ingestion of significant amounts of red dragon fruit may result in a reddish discoloration of the urine (www.medicine.com.my).
