As a tropical fruit, people who don’t know about the nutritional value of pitaya definitely don’t know how high it is. Many people like to eat pitaya, but how much do you know about the nutritional value of pitaya ?

Pitaya is rich in nutrition and unique in function. It has excellent effects on human health. It contains plant albumin and anthocyanins, rich vitamins and water-soluble dietary fiber, which are rare in general plants. Albumin is a viscous, colloid substance that has a detoxifying effect on heavy metal poisoning. Due to the lack of attention paid to the treatment and recycling of industrial wastewater and waste, various water resources have been seriously polluted by heavy metals. In addition to direct drinking water poisoning, humans are also prone to poisoning when they consume excessive heavy metals in food. When albumin encounters heavy metal ions in the human body, it will automatically combine with the heavy metal ions and be excreted from the body by the excretion system, playing a detoxifying role. Therefore, eating pitaya rich in albumin can avoid poisoning caused by the absorption of heavy metal ions. Albumin also has a protective effect on the stomach wall. Moreover, the albumin in pitaya flowers, fruits, and stems is very good and has excellent stability. The aggregation of these albumins constitutes the main component of cactus mucus.

In addition to rich albumin, pitaya also has a more special ingredient - anthocyanin. Anthocyanin is found in fruits and vegetables such as grape skin and red beets, but the content of anthocyanin in pitaya is the highest, especially in the red flesh fruit. It has antioxidant, anti-free radical and anti-aging effects, and can also improve the prevention of brain cell degeneration and inhibit the occurrence of dementia. At the same time, pitaya also contains vitamin C that whitens the skin and rich water-soluble dietary fiber that has the effect of losing weight, lowering blood sugar and moisturizing the intestines, and preventing colorectal cancer.
