Asparagus is delicious, but it comes with one quirky side effect: smelly urine. Here's why it happens and whether it's universal.
After eating asparagus, some people notice a distinct sulfurous smell in their urine. This occurs because the body metabolizes specific compounds in asparagus into volatile sulfur-containing molecules that are excreted. It's completely harmless. Studies indicate that around 60% of people don't detect any unusual odor, thanks to genetic variations. A small mutation in a specific gene means some individuals simply can't smell these compounds.
