# You Won’t Believe What Happens When You Eat Asparagus—Does It Really Change the Smell of Your Pee?! Ever uttered the phrase “my pee smells funny after asparagus”?
You’re not imagining things—科学研究 reveals that asparagus does affect the scent of urine, and the story behind it is both surprising and fascinating. If you’ve ever walked into a bathroom afterward and noticed a sharp, characteristically strong odor, you’re witnessing a natural biological quirk linked to a common vegetable: asparagus. ## The Science Behind Asparagus and Your Pee When you eat asparagus, your body metabolizes its unique amino acid, asparagine. Unlike most plants, asparagus contains high levels of this compound, which gets broken down into sulfur-containing byproducts—like methyl mercaptan and other volatile sulfur compounds. These compounds are water-soluble and travel through your bloodstream to your kidneys, where they’re filtered and excreted in urine.
