The average human being hosts tens of trillions
of microbes in and on our bodies, most of which reside in our intestines. Depending on the person, 2-6 pounds of our
entire weight could be purely microbial. That’s a lot of roommates who aren’t paying
rent, if you ask me. It turns out these microbial passengers are
both giving back to us and potentially sabotaging us… Scientists are calling this the gut-brain
axis… And some have even named it your ‘second
brain.’ It turns out that the teeming and diverse
community in our gut — acts as a collective unit with a mind of its own—quite literally. That’s right—we’re talking microbial
mind control, y’all. For example, your bacteria may be making food
choices for you. Some bacteria love eating fiber, some love
pure sugar or fat—and depending on your diet, you may be cultivating a gut population
with a preference for one over the other.. Whichever your ‘second brain’ prefers,
it’s probably going to to tell you what it wants—loudly—and then complain when
you don’t feed it: cue that ‘hangry’ feeling when you just really need a chocolate
bar at 3 pm. Your microbes do this by hijacking your neurotransmitters
until you feed them what they want. And when you do—there’s a wave a relief
as those bacteria release their happy feelings into your system…making you feel happy too. This interaction between your cravings, your
microbiome, and how your brain registers all of this is really complex, so if you want
to know more just let us know and we’ll look into it. When your bacteria feel happy, you feel happy
because… Bacteria, it turns out, communicate with one
another via neurotransmitter— the same kind of chemicals used in your regular brain: like
serotonin, dopamine, cortisol, and GABA. These chemicals transmit messages from one
neuron to another in your brain, and because you host so many bacteria — when they use
them it can affect you–and your mood–too. The thing is we’re still unclear on how
exactly these signals get from your gut to your brain—a likely candidate seems to be
the vagus nerve, a long nerve that connects your stomach and intestines to the base of
your brain, but it could also be your immune system or your endocrine system. Maybe it’s both! But the results that are coming in from this
kind of research are pretty remarkable. One research group at University College Cork
in Ireland fed Lactobacillus rhamnosus, a good bacteria — or ‘probiotic’ you can
usually find in yogurt — to one of two groups of mice.The probiotic mice were much more
likely to persevere and succeed in the face of adversity tests than those not treated
with the probiotic. They repeated a similar study in humans, with
the probiotic-fed humans displaying improved resilience to negative emotions than those
without the probiotic. Some scientists hypothesize that the root
evolutionary cause of this may be that your bacteria’s ultimate goal is to spread, so
when we cultivate a healthy gut population, the signals they send to our brain are encouraging
us to be happy and social and go out in search of food so we introduce them to more hosts… So, by shaking each other’s hand or kissing
other people we’re both picking up other peoples’ bacteria and spreading our personal
microbiomes — with all the benefits and drawbacks that entails. That’s terrifying. There’s all KINDS of crazy ways that the
bugs living inside of you are connected to your brain, and its a burgeoning research
field that has great potential for personalized medicine. Imagine your doctor sampling your microbiota
and knowing exactly which bacteria were sending you what signals and then being able to modify
your behavior, whether it be mood or diet-related, by supplementing your gut environment with
some new critters. Freaky. Want a healthy diet of science in your life? Why not subscribe? And watch this video about how antibiotic
resistant bacteria have a new ENEMY in the CRISPR pill. Yeah. It’s cool. Did you know that fecal transplants can potentially
be life-saving? That’s right, a transplant of a healthy
donor’s stool could save someone suffering from a fatal gut infection. The power of poop! Thanks for watching.

  1. Hmmmmm…!
    Well that street work 2 ways !
    Bad microbes like "H.Pylori" could have very bad influence on patients mood !
    Ex. These tend to make you have irrupted bowl and gives us reflux !
    Study on behaviours of people infected with this microbe might prove or disproved this very dangerous hypothesis !
    Also if we stretched it a little bit that might mean Viruses might have same influence via deferent neurological channels other than proposed vagal nerve !
    This might mean virtually "any" infectious disease might have influence on patients mindset to push itself to survival via spreading out !
    You know that's creepy !

  2. OMG YES, I NEED THIS! Please, dig deep into this subject; and don't forget about lactose intolerance and the consequences of cutting dairy off the diet. I was super healthy until I somehow develop lactose intolerance. Now I need to take probiotics at leat once a day to live a normal life.

  3. Well I love my gut flora because they like Dr Pepper so there fore I like Dr Pepper their happy therefore I’m happy much love gut flora stomach and brain high five

  4. omg omg omg…my gut is telling me it wants some McDonalds and I keep telling it no!!! My gut is now pouting about it and I told it to "go to your room!"

  5. So thats why i feel like dying when i wasnt able to eat any form of rice for 3 days. I felt like i was still hungry even after eating but when i try to eat meat or mashed potato or any form of food, my body would say its full but i will still feel hunger and craving for rice

  6. whoa! ya i would like to see more. ive heard a few things here or there about gut bacteria but i havent seen a ton of articles (its not like im searching for them). This might be a classic case of "more research is needed".

  7. oh, yeah, we'd like to see more detailed explanation for that interaction, this is actually really interesting

  8. I had some pretty powerful antibiotics and I've commited genocide against my bacteries. Month and a half with ragin diarrhea!

  9. yeah lol, parasites do that and pathogenic bacteria maybe too.that's not normal.what are we now brainwashing channel for ignorant sheeple?

  10. I like the comments for this video. It seems that smart people are funnier and less hateful than the average commenter.

  11. Wouldn't our guts be our third brains since our reproductive organs are generally referred to as our second brains???

  12. Corrected references:

  13. remember if you keep your evil bacteria happy they will make you sick. Breed up the good ones with healthy food before listening to the cravings

  14. I wonder what would happen if I suddenly became vegan. Would some of these microbes die, or what would happen?

  15. remember when SciShow had that female host? Remember it didn't go over well? Remember when people cried sexism? THIS IS HOW YOU PRESENT!!! GOOD JOB…AND HOW A WOMAN….AND WOW LOOK AT ME LIKING THE VIDEO

  16. My bacteria like drinking beer and eating bacon. They also absolutely love playing video games instead of working out, so it is not my fault that I'm getting fat. It's science. More bacon is required.

  17. So.. Jamie Lee Curtis is always smiling and happy and kickass due to all the yogurt/probiotic she's eaten? Seriously, could an injection of healthy particular microbes help those who are overweight or underweight?

  18. On a serious and personal note, I like to eat girls assholes out during 69ing. I know someone on here can relate and a lot of ppl do this mainly when the recipient is attractive. Is it possible we are trying to obtain their gut microbes or gut microbes are a reason for this behavior?

  19. i knew it, physical contact with some peeps might make you one of em and vice versa, just dn't have the science to prove it. haha

  20. Researchers will study the gut health of people with Alzheimer's to see if diet can play a role in managing the behavioural and psychological symptoms of the disease.

  21. Thanks! This is not really that surprising. We have more microbes (by weight) in us & on us, then there actually is of us! That's right – you're made up of more 'germs' than human tissue. So it's not really a stretch to think that these bugs send signals to us, as well as to each other. Our bodies need to be able to respond in some non-harmful way to our microbiome, so that we can live as one (generally) harmonious unit. But… consider the following bugs**t statistic: upwards of 40 million people – in the U.S. alone – are infected with something called toxoplasma gondii. Only a smaller percentage of us exhibit symptoms – called toxoplasmosis. But this single-celled parasite is known to send chemical signals that can actually control some animals' behavior; causing them to engage in highly dangerous situations – even fatal ones – all to benefit the spread of itself from one animal to another. A sobering thought. Anyway, thanks again for the video. 𝓡𝓲𝓴𝓴𝓲 𝓣𝓲𝓴𝓴𝓲.

  22. I love the way she speaks, so clear articular and she ENUNCIATES. Her pace is also great, not too quick, not too slow, and the timber and tone are also just balanced. Some people just have a gift for communicating,.

  23. Salute To All Of MY CHOSEN Ones Off In This Motherfucker Mane!!! (EYE) Am The Black Dragon!!! (INTELLECTUALLY) IMMORTALIZE ME SHAWTY!!!
