The pitaya, also known as the dragon fruit, is a fruit native to Central America. It is oval, with thorns on the outside and three varieties can be found: yellow on the outside and white pulp with seeds on the inside, red on the outside, and white pulp or red pulp with seeds on the inside. It is very aromatic and its flavor is very sweet and pleasant.

When consuming the Sonora pitahaya, one must keep in mind that it is a completely organic fruit and that the characteristics of its ecosystem provide it with a flavor and properties different from other parts of Mexico. The pitahaya has antioxidant properties, which is mainly attributed to the presence of betalains that give it the red color; therefore the fruit represents an alternative to increase and diversify the intake of antioxidants among the population of arid and semi-arid areas of Mexico.

The pitaya is a treasure from the nutritional point of view, it contains antioxidants, mucilage, ascorbic acid, phenols. It is rich in Vitamin C, it also contains B vitamins, minerals such as calcium, phosphorus, iron, and it has high water content and has vegetable protein and soluble fiber. The edible seeds contain beneficial fatty acids. And one of its most outstanding properties is its anti-inflammatory and antioxidant action, which is why the WHO recommends its consumption.

Despite its peculiar appearance, the pitaya is eaten like any other fruit. It is cut in half and the pulp is spooned out, and the seeds are also eaten. It can be incorporated into the preparation of smoothies, ice cream, and cakes, and is also used to make jams and competes. If pitahaya is bought in the public streets, it is necessary to pay attention to the state of maturity of the fruit and to check that its peel is not burst, to avoid consuming a product that could have been contaminated during its collection, transport, handling, and commercialization, and cause intestinal infections.

The term pitaya or its variants such as pitalla, pitahaya, pitahalla, pitajalla, pitajaya, pitaya de mayo, pitaya xoconostle, among others, is commonly used in the different states of Mexico to refer to the fruits of several species of the genus Stenocereus that produce the fruit called pitaya, and "pitahayas" or "pitajayas" to the fruits of Hylocereus Selenicereus. The former are also known as columnar cacti and the latter as vine cacti.

Pitaya and Pitahaya: aren't they the same?
