Skunks stink when they pee normally

Why the urine smells strange after eating asparagus

It is easy to tell that asparagus is diuretic after eating some of the pale sticks. The vegetables consist of more than 90 percent water and also contain potassium and aspartic acid. The liquid drives through the kidneys out of the body and thus the asparagus eater to the toilet. It then smells unpleasant there. But not with all people.

Research into this has been going on since the end of the 19th century and for a long time there was no agreement on whether the urine does not stink in some people or whether there are people who simply cannot smell the odor, even though it exists. In the meantime the riddle has been solved. The answer is: both are correct. Because whether the urine smells like eating asparagus and whether you can smell the scent is a matter similar to rolling your tongue or wiggling your ears. Some can and some cannot.

Genetically conditioned

People whose urine smells unpleasant after eating asparagus have an enzyme that breaks down aspartic acid into sulphurous substances. And sulfur does have an unpleasant smell. Those who don't have a smell of urine also have to go to the bathroom, but they don't reveal what they had for lunch. There are also people who cannot smell the odor of the urine after consuming asparagus, even though it is there. This is due to a mutation in the gene for an olfactory receptor. You suffer from a specific anosmia, i.e. a selective non-smelling.

So it can be summarized: There are people who do not produce the odor in the urine after eating asparagus and there are those who cannot smell it. One thing is certain, however: the unpleasant odor in the urine after eating asparagus is harmless and not a symptom of illness. On the contrary: Asparagus is very healthy and contains a lot of fiber, iron, vitamins and calcium. It is a good remedy for constipation and has a positive effect on the heart and circulation.

So: bon appetit.
