Is Eating Your Boogers Good For You?

Cindy asks: This is kind of ewww, but I read that eating your own boogers helps boost your immune system.  Is this true?

picking-noseDoes physically taking boogers out of your nose, putting them in your mouth and swallowing boost your immune system?  The short answer is probably not.  You ingest your snot all the time without needing to channel it through your mouth. So if there is a benefit here, you get it without needing to munch your nose nuggets.

That said, there are a couple medical professionals willing to comment on the benefits of mining for green candy, particularly touting benefits to one’s immune system.

One of the more credible sounding proponents of the habit is Scott Napper, a professor of biochemistry who made waves around the world’s media outlets in 2013 when he half-heartedly proposed to a group of his students that eating one’s boogers allows our bodies to safely develop anti-bodies to the weakened pathogens present in our snot and noses. He also suggested that the reason boogers have a sugary taste is to entice children to eat them, thus helping bolster their immune systems… It’s evolution.  You can’t fight it.

While he was mostly just trying to get students interested in doing science by an unconventional proposition, Napper’s hypothesis, thanks largely to the media, has since morphed into many seeming to think that he actually did some sort of study on this, and that there is evidence to support it.  The truth is that to date no such study has been done, though Napper has expressed interest in doing one, and no doubt would win an IG Nobel Prize for his work if he ever does it.

Of course, as you might expect, finding a large sample size of volunteers is something of a hurdle.

Another name that comes up whenever the subject of eating boogers is mentioned is lung specialist Dr. Friedrich Bischinger.  In 2004, he reasoned that eating boogers is healthy for a similar reason that Napper did.  The Museum of Hoaxes did a little background check on the good doctor and noted that Dr. Friedrich Bischinger has never published a medical study on the subject and his original quote about the benefits of eating boogers comes from a poorly translated  interview with a German magazine. As far as we can tell, Bischinger has never really elaborated upon his original hypothesis since then.

So without any study to date on the subject, to answer the question at hand, we’ll need to analyze the plausibility of the hypothesis.  Is he correct about the microbes and other things in your nasal mucus?  Yes, that’s one of the functions of it- to help filter out dust and pathogens.

But there is a problem from here.  As pointed out by Dr. William Schaffner of Vanderbilt University, we humans ingest our nasal mucus all the time- day and night.  The wet mucus in our noses generally gets shuttled back into our throats via cilia, and sometimes via simple gravity when our heads are in the right position.

So, if you didn’t know it before reading this article, you ingest boogers every day.  You might have just swallowed some right now.  Think about it.

Needless to say, few medical professionals give credence to Napper’s or Bischinger’s  hypothesis. In order for it to be true, there would have to be something special about the relatively dried mucus that you have to pick out over the wet or dried mucus you snort up and swallow.  And there is simply no reason to think there would be any significant difference other than, potentially, moisture content.

However, not all hope is lost for you bogey fans, as Dr. Joseph Mercola notes, there’s an increasingly popular hypothesis that our obsession with cleanliness as a society is causing more of certain types of diseases because our bodies aren’t being exposed to certain pathogens regularly, and thus our immune systems are weaker as a result- the so called “Hygiene Hypothesis.”

So it is plausible enough that ingesting mucus does indeed expose our bodies to pathogens it can handle and is helping the immune system in this way.  But, as mentioned above, this happens anyway. There’s no need to manually pull it out of your nose and put it in your mouth… unless of course, you like it.  Either way, it’s going to end up in your stomach.

That said, while it may seem gross to those of us who’ve never tried (or don’t remember- nearly all children do this at one point or another), according to the sparse few studies that have been conducted on booger eaters, the vast number of people who eat their nasal mucus find it palatable, which probably isn’t a surprise to anyone as if they didn’t, they’d likely just stop. As Sidney Tarachow in a 1966 report on coprophagia (the compulsive eating bodily secretions) noted, “persons do eat nasal debris, and find it tasty, too!”

So to sum up, at least to date, there is no scientific proof that ingesting snot by passing it through your mouth is beneficial.  That said, it is plausible that the snot we do all ingest all the time is benefiting us in the way snot-eating proponents suggest.  It’s just that we don’t need to put it into our mouths to see the benefit, if such a benefit does exist as hypothesized.

In the end, though, as long as you’re careful, picking and eating is not generally going to hurt you, and many find it tasty… so, if that’s your thing, bon appétit!

Bonus Facts:

  • The correct term for eating one’s own mucus is the decidedly less off-putting sounding term: mucophagy, and according to the BBC, at least 10% of people who regularly pick their nose “occasionally practise mucophagy“.  Further, about 90% of the adult human population in the same survey admitted to picking their nose (a figure that climbs to 99% in younger people).  So the habit is oddly common considering the extreme taboo that surrounds it.
  • As mentioned, for the most part, the act of picking one’s nose is entirely harmless and as long as you’re careful or don’t try to cram a fork up there or go knuckle deep or something, in the vast majority of the cases, you’re not going to do yourself any lasting harm.  That said, picking one’s nose is still listed as one of the leading possible causes of nosebleeds. For instance, in a 2001 study on rhinotillexomania (compulsive nose picking), it was discovered that 25% of teenage subjects who mined their nose 4 times per day or more suffered from nosebleeds as a result of their activities.
  • In a study published in 2006 on the link between nose picking and staphylococcus aureus (a bacterium commonly linked with skin and sinus infections), they found that habitual nose pickers were about 20% more likely than non-habitual pickers to have the bacterium present in their nose, suggesting a “causal link” between the two.
  • Because blowing out dried snot from your nose can sometimes require a great deal of pressure, which can cause damage to your nasal septum, it is generally recommended that you simply use a clean finger to gently remove the offending nose crusties instead-  in the process joining the 90% of adults who stood up and proudly proclaimed in the above study that they are nose pickers.

  • Interesting article. No where in the article was the possibility of transference of viruses or germs from one’s finger might be ingested as well, thus introducing them to the digestive system and helping to build an immunity to those illnesses.

    • Daven Hiskey

      Good point. If they Hygiene Hypothesis is correct, regularly putting your fingers in your mouth may well be where any potential benefit here is coming from rather than the boogers themselves. :-)

  • Never refer to Joseph Mercola as a credible subject matter expert. He’s a quack.

  • Does the body get any nutrition from eating boogers? If I was lost in the desert and had a bunch of boogers to eat, would it be beneficial to my survival to eat them?

  • sounds tasty. :)

  • Here’s a fact that most won’t mentions. You can get extremely sick from eating body waste (excrement). That’s really was this is.

    • False. I have been eating snot, mucus, and boogers since I was a kid. I am 35 now. I rarely get sick but maybe once a year.

    • Your mucus is not excrement, which is what boogers are made of. It lines your esophagus you nasal cavity there are tubes that run from your ears to your throat to drain ear wax. excrement or human wast refers to; poop, shit, doodie, the brown stuff that i imagine comes out of your mouth.
      Lol I cant even.

  • I admit that ive eatin my boogers my whole life and I havent been sick in almost 10 years.

  • I eat buggers regularly. I started 5 years ago as I was diagnosed with Kennel Cough. Since eating buggers, every day before my main lunch meal and before dinner, I’ve been healthy and surpassed my sickness.
    Can not stress it enough, but buggers healed my condition.

  • I wonder how many people in the world use boogers or snot for sexual purposes?

  • hey. I’m 37 years old, i ate my boogers as long as I remember. about the sickness, well i really don’t remember last time i have cold, none nosebleed, etc.

    I’m married to my beautiful wife, she always is disgust from it (I hardly try not to do it in front of her).

    got 3 children, 2 girls & a son. my son of my eldest daughter eat their boogers too, but not as many times as I do.

    everything is Normal, Not a single illness for them. we are all truly healthy.


  • Tastes great on a burger too!
    Snot burgers are more flavorful and juicy (unless you get the crispy ones, tasting like bacon)!

  • I’m honestly happy that I did some research on this particular subject. I’ve always thought that I was different, that no one in their right mind would pick their boogies and munch on them as if it were candy. I, honestly, began to think that I was gross and it was just…horrible. I wanted to see if it was a health defect, if I was “abnormal”.

    I can’t tell you how much this really means to me, and to see all of the comments below this article just helps me understand that really, I’m not the only one. I can’t possibly tell you the amount of disgust I held for myself until I came across this article and all of the commentors below it. It just felt… I felt like things were right for once.

    I so rarely get sick, but when I do, man it’s horrible. I’ve eaten my boogies ever since I could remember. I’m 22 years old now, but I never stopped to think about the consequences of my actions or the health issues that my entail with eating boogies.

    I guess….I guess now I have some peace of mind. ^_^

  • I’ve been eating boogers for the past several years now and have found them to be a terrific snack between meals. I’ll usually indulge on a few when waiting at a restaurant for my entree to arrive.

    Stopped at a red light is also a good time for a quick bite. However, I don’t recommend picking and eating while driving on the freeway as it can become distracting and take away from focus on the road.

  • I have always eaten my boogers occasionally on a daily basis. I am 30, and I rarely get a cold or fever (maybe once per year). I am a healthy person. More peer reviewed studies on this topic would be a good thing.

  • The practice of having a hankercheif with you today is become far less freaqent. Dare I sugest that not knowing what to do with boogy after picking it is the problem, so people tend to eat it.

  • I enjoy eating boogers on occasion. However, i’ve discovered when i start to feel a fever coming on i’ll eat a lot more and within a day or two I’ll feel great. I’ve saved a lot of money with this mothod not having to make doctor’s appointments.
