Despite what many people believe, cherries cannot in fact cause red urine. There are certain foods that can cause your urine to turn if enough is consumed though, such as beets. Other causes for red urine include bladder stone, kidney infection, enlarged prostate, certain medications, food dye, bladder or kidney tumor, and Wilms’ tumor in children.
As for food like beets which can in fact turn urine red, one has to consume a massive amount of it at one time in order for this time to happen. If you find that your urine does turn red after consuming a certain food, it is most likely not serious and does not require any medical attention whatsoever.
