If You Smell Funky Asparagus Pee, You Have This Special Gene

If You Smell Funky Asparagus Pee, You Have This Special Gene

Have you ever eaten asparagus and noticed how it changes the way your pee smells? You may have heard about the phenomenon but wonder why it seems to affect some people and not others.

Many researchers agree that the smell of asparagus pee results from the metabolism of a compound found exclusively in asparagus known as asparagusic acid. The compound is broken down into sulfur-containing compounds such as methanethiol, dimethyl sulfide, and dimethyl sulfoxide –which are responsible for the most prominent odor detected in asparagus pee. All of the above components can easily vaporize into a gaseous state at room temperature [1] –which brings them to your nose.

Why can’t some people smell it?

The whole asparagus pee smell issue is a little complicated. Various theories attempt to explain why only some people can detect the odor in their pee after eating asparagus. Some researchers suggest that people who don’t detect the asparagus smell in their pee do not have the ability to produce the scent; others argue that everybody breaks down the asparagusic acid in the asparagus equally, only that some people simply lack the ability to detect the smell.

M Lison and other researchers [2]carried out a study to explore this phenomenon back in 1980 and discovered that actually everyone produces this “asparagus smell” but only a few people were able to smell it. The study also revealed that people who were able to detect the smell could even smell it in the urine of those who could not smell it. This reinforced the idea that the difference in the two groups of people was more as a result of perception than production.

Another study published in the Oxford Journal [3] throws in yet another interesting twist. The study revealed that there still existed some differences even within the groups of subjects who could detect the smell and those who could not. Nevertheless, most scientists generally seem to back the theory that perception is the main reason some people are not able to detect any difference in the smell of their pee after eating asparagus.

Could the variation be genetic?

A DNA-sequencing company (23andMe) carried out an investigation in 2010 to find out if the ability to smell asparagus pee was linked to any genetic component. The study asked subjects if they could detect any odor in their urine after eating asparagus, and investigated the genetic similarities in the two groups. Findings revealed that the ability to detect the asparagus smell was linked to a certain DNA sequence that varied among different people. This means that a single mutation in the genes responsible for smell [4] may be the reason some people are unable to smell asparagus odor in urine.

When all is said and done, it’s important to mention that only about 25% of the population seems to have this unique DNA sequence that allows them to smell asparagus pee. So basically, you do not need to worry about a thing; if you are able to smell the funny scent in your pee after eating asparagus, you’ve got a good nose and can be proud of it.

How to Tap Into the Power of Positivity

How to Tap Into the Power of Positivity

As it appears, the human mind is not capable of not thinking, at least on the subconscious level. Our mind is always occupied by thoughts, whether we want to or not, and they influence our every action.

When we were still children, our thoughts seemed to be purely positive. Have you ever been around a 4-year old who doesn’t like a painting he or she drew? I haven’t. Instead, I see glee, exciting and pride in children’s eyes. But as the years go by, we clutter our mind with doubts, fears and self-deprecating thoughts.

Just imagine then, how much we limit ourselves in every aspect of our lives if we give negative thoughts too much power!

We’ll never go after that job we’ve always wanted because our nay-saying thoughts make us doubt our abilities.

We’ll never ask that person we like out on a date because we always think we’re not good enough.

We’ll never risk quitting our job in order to pursue the life and the work of our dreams because we can’t get over our mental barrier that insists we’re too weak, too unimportant and too dumb.

We’ll never lose those pounds that risk our health because we believe we’re not capable of pushing our limits.

And we’ll never be able to fully see our inner potential because we simply don’t dare to question the voices in our head…

But enough is enough! It’s time to stop these limiting beliefs and come to a place of sanity, love and excitement about life, work and ourselves.

So, how can we tap into the power of positivity?
