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 Practice Positive Meditation in 2 Simple Steps

How to Practice Positive Meditation in 2 Simple Steps

Just by simply spending some effort and time, staying positive every day can be easily achieved. All that is required is a fraction of your time, 10-15 minutes a day to cultivate the positive you!

But first, what is really positive thinking? Do you have to be in an upbeat, cheerful and enthusiastic mood all day to be positive minded?

No. Positive thinking simply means the absence of negative thoughts and emotions – in other words, inner peace!

When you are truly at peace within yourself, you are naturally thinking positively. You don’t have to fight off negative thoughts, or search desperately for more positive thoughts. It just happens on its own. And here are 2 positive thinking meditation tips to empower you:

1. Relax as You Meditate

A powerful, simple yet rarely used technique is meditation. Meditation doesn’t have to take the form of static body posture. It can be as simple as sitting in a comfortable chair listening to soothing music. Or performing relaxation techniques such as deep breathing exercises.

Meditation is all about letting go of stressful or worrisome thoughts. That’s it! If you spend just a few minutes per day feeling relaxed and peaceful, you automatically shift your mind into a more positive place. When you FEEL more relaxed, you naturally THINK more positively!

Start with a short period of time, like 5 or 10 minutes a day. You can meditate first thing in the morning, during your lunch break, right before you go to bed at night, or any time. The most important thing is to consciously let go of unproductive thoughts and feelings. Just let them go for those few minutes, and you may decide not to pick them back up again at all!

2. Practice Daily Affirmations

Positive affirmations can be used throughout the day anywhere and at anytime you need them, the more you use them the easier positive thoughts will take over negative ones and you will see benefits happening in your life.

What are affirmations? Affirmations are statements that are used in a positive present tense language. For example, “Every day, in every way, I’m getting better, better and better” is a popular affirmation used by the late Norman Vincent Peale.

So how does one go about using positive affirmations in everyday life? Let’s look at some guidelines to follow when reciting your daily affirmations.

  1. Use first person pronouns in your message (I)
  2. Use present tense (I have)
  3. Use positive messages (I am happy)
  4. Repeat your affirmations on a consistent basis

Affirmations have to be said with conviction and consistency. Start your day by saying your affirmations out loud. It wouldn’t take more than 5 minutes to repeat your affirmations; yet when done consistently, these positive affirmations will seep into the subconscious mind to cultivate the new positive you.

Here’s an example of a “success affirmation” you can use on a daily basis:

I am successful in everything I do. Every venture I get into returns wealth to me. I am constantly productive. I always perform to the full potential I have and have respect for my abilities.
My work is always given positive recognition. I augment my income constantly. I always have adequate money for everything I require. I spend my money prudently always. My work is always rewarded.
