Red feces excreted after eating red dragon fruit will disappear in about 1 to 2 days, not more than 3 days at most. Also, the urine discharged from eating red hearted dragon fruit is red in color.

This red feces or red urine is a special odor, because the anthocyanin contained in dragon fruit exceeds the upper limit of the human body's decomposition and metabolism, so it is discharged with a color change in the feces.
