What happens when you eat red pitaya and urine turns red?

Eating red pitaya can cause urine to turn red. Red pitaya causes urine to turn red, not because of anthocyanins, but because of betanin. The main chromophoric group of betanin is betaine, which will be hydrolyzed by the digestive system in the human body. The chromophoric group of betanin is relatively stable and is not easily degraded by the human body. Therefore, there will be feces or urine discharged from the urinary system and digestive system, so that urine is reddish, or red stool when defecating, sometimes there will be reddish sweat when sweating. Therefore, eat red pitaya urine red do not be afraid, generally drink more water a few days will disappear. If you are not assured, you can do routine urine examination to see if it is true hematuria.
