Answer: Asparagus Urine

If you’re one of the people who can smell the pungent and sulfuric smell of urine produced after a meal heavy with asparagus, you’ll likely be shocked to find out that you’re in the minority. Although the majority of the people in the world excrete extra sulphur-related compounds in their urine after consuming asparagus, only about 22% of the population has the specific olfactory gene that makes them sensitive to the smell. Some people, it would seem then, can eat their asparagus blissfully unaware.
