Why does urine smell like corn?

Urine doesn't usually smell like corn unless you have been eating a lot of corn or foods with corn syrup. This is because corn is a food that is high in sugar and sugar can cause your urine to smell sweet or even like corn. If you have been eating a lot of corn or corn syrup and your urine smells like corn, it is not a cause for concern and will likely go away on its own. However, if you are concerned about the smell of your urine, it is always a good idea to talk to a doctor.
