2. Coffee
Have you ever had the experience of drinking coffee, then heading to the restroom only to have your urine smell — well, kind of like coffee, only stronger? Experts believe that this happens because coffee is a diuretic and it makes you need to urinate more frequently. As a result, the uric acid, chemicals and vitamins may be more concentrated in the urine, leading to a more pungent odor. Also, experts think that the insoluble oil released by coffee beans when they’re roasted may affect the odor of the urine, as well.
