I suffer from anxiety related stress and I find taking Bulgarian yoghurt helped tremendously in stabilizing my mood and anxiety. I believe there is a strong correlation between the mind and the gut biome.
That or you're experiencing the placebo effect. I'd try regular, non-bulgarian yogurt without knowing thats what you're eating.
From what I know, there are good studies documenting the effect of Lactobacilli on the physical health. I don't know anything about mental health in relation to the bacteria, however, Japan has tried to 'copy' and be able to implement the bacteria in dairy products who lack it. As a Bulgarian myself, I am happy there is someone who is aware of its benefits, and I suggest that more research is definitely needed.
@@iloveplasticbottles Maybe Bulgarian yoghurt is the same as Greek yoghurt? Maybe it is live rather than pasturised to death? I dont know but it would make a difference.
@@iloveplasticbottles gaba is produced in the gut so if he has a low gaba deficiency his body won't be able to tolerate stress and it'll lead to anxiety symptoms
Hi there!
Since you are interested in food:
It is said that by 2045 we would be producing 40% less food than what we are producing right now and our population would be over 9.3billion people. #nosoilnofood
We can take action now and turn this situation around, and create a significant change. #SaveSoil #ConsciousPlanet #Mentsükatalajt #Tudatosbolygó
I thought it's important to share🌿
Love from Hungary 🌏🌎🌍
When someone say "my gut is telling me ....", that means that their gut were actually telling them
"Ay! Cool it on the McDonald's up there!"
@@ToiletPlugger😂
Yes bacteria 🦠 is your friend
I was completely cynical about this "your gut can affect your brain " theory until a recent bout of food poisoning. I felt perfectly fine after 12 hours or so - except I had zero interest in food which lasted several days. My doctor said my stomach needed a "reset" and probiotics did the trick. I was amazed how much an illness could completely change my thoughts.
1:47 The Vagus Nerve connects the ENS to the brain? So, what happens in Vagus doesn't stay in Vagus.
I haven't got the vagus idea what would happen.
Not enough information, its too vagus
Only if your "second brain" is the one in charge .
you win
What happens in Vagus stays in vagus :)
This is one of the best videos! It is very interesting, when she talked about how a shy mouse can change its behavior, just by changing the bacteria in its gut, that groundbreaking to me. Thank you Olivia!
:) In real life that's so logical. When a person is hungry even if they are shy, they might go ask other people for food or just find them self surprisingly more out going to a point where they might "find them self" stealing food sometimes (it's not an excuse tho). Scientifically it's all gut bacteria!
What i wonder about now : does any kind of bacteria interfere when people are scared, hopeless, traumatized, happy, ... even when they are not hungry?! in other words can the emotional state or even the personality of a person be related to it's bacteria?
I think Naturopathic doctors can have some very misguided views at times, but in this situation I've seen that they definitely have a point. Many have been pointing out this connection for decades and "prescribing" remedies for stress through this medium.
I am so glad you presented a video on this topic - As a microbiologist suffering with Ulcerative Colitis, I find this to be a highly important subject and the explanations you give are more than relevant to my dissertation. I cannot wait to see how what I learnt about stress and the microbiome affects later studies :)
glad to not be a fecal transplant recipient mouse
Research on microbiomes is really hot right now, they seem to have an impact on basically everything
@N K Her early diet failed to turn-on the usual sexuality genes. This is very common these days of GMOs and pesticide food consumption. It is WHY the entire gender confusion expression we see in the news. This is new and not something which was hidden by a tyrannical system run by Charlton Heston and Ronald Reagan. We do have millions more severely screwed up people with gender issues now because of a crappy food supply. The bugs who benefit don't want us changing this in fact the opposite.
It really is. Did you know that changing what you eat can change your gut microbiome in just 2 days?
Remember that old saying....
"You are what you you eat"
Healthy food, good excercise, good friends, and love self. Keep it simple!
so I CAN fill that hole in my heart with food I just haven't found the right food.
64standardtrickyness, I know you mean to be funny, but people will agree w/you out of loneliness. You can’t fill the hole w/food; you have to switch your focus away from the hole. Focus on a fuller life - that will start to close the hole.
My grandmother worked for a "resort" in Genova, Italy back in the 1950's where the "rich & famous " would go for a few months to completely cleanse their gut & mind✌🏻👏😱
I’m so glad I took Ayurveda as my way. The Ayurvedic concept of food affecting mental state (Satvik, Rajsik and Tamsik food) is just one among many things which are now making complete sense to me.
I'm an italian medical student and I'd like to compliment this channel, your contents and divulgation efficacy are really amazing! Go on like this
This is really interesting to me, especially as a guy who's had ulcerative colitis for about 10 years now and has struggled with depression for about the same time frame. UC sucks, but UC AND depression make a pretty brutal combination.
Didn't Hippocrates advise us "Let food be thy medicine and medicine be thy food"
And he also said, "all disease begins in the gut."
And he also said, "What's for dinner?"
Great video! To add to this, nutrition issues can result in anxiety. For example, magnesium deficiency can be a problem. This deficiency may result from our soils being depleted of magnesium, the increased amount of magnesium used by the body during stress, medications like birth control, and not eating enough magnesium. One good food source of magnesium (and delicious) is pumpkin seeds!
For the last two years I have had a dysbiosis, Small intestinal bacterial overgrowth. During that time I have been treated with antibiotics twice which has let me perceive at least 4 drastically different gut microbiomes. I have a first hand perspective of drastic mental changes that accompany changes in human gut flora. In the last two years I have felt some of the worst forms of mental illnesses from being suicidally depressed, to crippling anxiety that caused me to become agoraphobic. I have been able to treat all of my symptoms of SIBO, including the mental, with a short dose of antibiotic and long term probiotics. To me it is no question that the human microbiome is at the central cause of everything from IBS, to many mental illnesses. It is my belief that dysbiosis are getting more prevalent due to the increase in consumption of highly ferment-able foods and the widespread use of antibiotics.
Margaret Thatcher I used what's called a low fodmap diet to find what foods I can eat. The diet was at first very restrictive of fruits and vegetables. As I progressed I found that pretty much only wheat and corn are the main irritants to my gut.
Iron Manatee I’m sorry you had to go through that. I hope you are doing better now. I too had to go through two rounds of strong antibiotics and I literally could feel myself becoming more and more depressed everyday. Hopefully doctors start to listen to us.
Very interesting.
Literally 3 1/2 years ago I had to go to a doctor because I was severely ill. He doesn't go through insurance because he really tries to get to the root of the problem. He found out my whole GI tract was inflamed and I had horrible IBS (while my other dr just said pretty much that's the way it is). When he told me that 80-85% of serotonin was made in my gut and could explain why I was so severely depressed and having over 10 panic attacks a day. Once he worked on helping heal my gut- I honestly had hope again. I thought I was dying and there was no way out of the mental hell I was in. By the grace of God. I am doing so much better. And honestly, could be doing even better. I just need to be more intentional. But he knew all of this stuff for years!! If you are not doing well. How is your gut?? I now don't eat gluten (inflamitory or milk) to keep the inflammation a bay. I know some people don't get this whole gluten then but trust me. If you have ibs, anxiety, depression, getting sick all the time-, there's a reason. Don't just let a doctor give you some pills to manage it. Dive in and find what's the problem. There's hope! I will share this with who ever because I know the mental hell and physical pain and how hard that was.
Thanks for writing this.
It helps me. M suffering from anxiety nd don't know how to deal with it. Doctor advised for yoga nd meditation. I will be thankful if you can suggest me some thing to cure it. (Sry for poor english)
Could you elaborate on the "helping heal my gut" part beyond removing gluten? Diet changes? Probiotics? It is not something you covered in your post and I'd like to know more.
Romeo Romeo, are you saying the doctor prescribed NO meds to help with the attacks?!? That is incomplete response to your problem. Yes, yoga and meditation are good ways to fulfill the exercise part, and diet IS important. But unless these have eliminated your problem, you should have meds to carry you through attacks.
I should mention that I used mine as a last resort, and was able to calm myself when an attack began in part by knowing tat the meds were on the cabinet if I needed them. Consider asking your doctor for fallback prescription.
TMI but was one of your symptoms a very loose stool 👀 (asking for myself)
Xxfreak054xx what is the name of the doctor you went through
This really does give some alarming concerns for how various antibiotics can severely damage your mental health.
kiwiboy1999 ...not really.
Not really, at all. The antibiotics we take have minimal effect on our microbiome for many reasons. A major one being that the microbes we don't want usually have a different make-up than the ones we do. We also have so many of the good microbes that any damage to their numbers is quickly repaired.
I have one response to that; we apparently had no idea that the intestines, and the microbes within, had a large impact on mental health and general mood. it'd be foolish to rule out us simply not knowing the potentially damaging effect you'd expect from killing microbes.
Eh, it depends. There's a lot of antibiotics that can give you a C. Diff infection because the good bacteria were killed too.
But if we have never measured a noticeable mental effect from antibiotics. Why would it suddenly start being an issue?
I’m on Antibiotics and Antidepressants, your video is scaring me
It made me really damn happy when Olivia started the episode so chipper and excited! She's my favorite host SciShow has ever had.
In medicine (and psychology) I predict this is going to be the century of the human microbiome.
Stress causes illness, resistance in life causes the body to go into fight or flight. When discernment kicks in. Use it! It's a message from the brain to protect you..... If you live in truth, you'll do what is right, and your gut will flow...and your immunity will be most healthy....live in truth for a healthy life.
Gut instinct/gut feeling really do have a basis in reality after all.VERY INFORMATIVE VIDEO.
Super interesting :-)
one channel watching another channel.
mind blown!
Rare, don't steal.
original character doughnut steel.
You should make a video on Toxoplasma gondii and all the weird research into it!
I always thought it was the Vegas nerve. Today I found out that I'm a moron.
Does this mean people with the lactose mutation could have different brain chemistry to people without the mutation?
Nice thought!
Even worse. Proof that Vegans actually have a different brain than regular humans!
Yes actually, that's possible. I've been working in a feeding behavior-based neuroscience lab for some time now, and the gut-microbiome-brain axis is one topic we are currently exploring. The lactose mutation would cause there to be an increase in sugar availability for those microbes that can metabolize lactose, giving them an advantage. Larger colonies of those microbes could affect the chemistry of the enteric nervous system. (By-products of lactose metabolism could also play a role; gas production in response to lactose availability for example could give a separate species a carbon source). It's an extremely complex system and literally any changes can have an effect on the entire system as a whole.
Sarcastic dog whistle. Props.
Wouldn't the pressence of lactase in the gut deprive the microbes that metabolize lactose of their sustenance, putting them in a Disadvantage?
Thanks for doing an episode on this; I've been wanting one for a while.
what we ACTUALLY understand about nutrition and everything that's involved with it, bacteria, microbiome etc doesn't even scratch the surface of what's going on... this is exciting, proper understanding of this kind of information changes EVERYTHING
I’m here trying to build a case for a natural approach to treating my MS - by strengthening my blood brain barrier/improving my gut-brain microbiome. At the moment, I don’t believe I actually have MS. I believe that the antibiotic I was on for an infected finger crossed my blood brain barrier because it was weak, poisoning me and causing damage to some of the myelin and altering my body’s functions. Lots of natural approaches to treatment use blood brain barrier/gut-brain microbiome science. I’ve decided that this is the best approach for me because it means that I’m completely in control of my own “treatment” and won’t be opening myself up to unwanted side effects or risks. I *think* that MS, Alzheimer’s and other neurodegenerative diseases are actually results of weakened blood brain barriers/gut-brain microbiomes and that by finding ways to strengthen the barriers between the body and the brain, we can reduce or even eliminate the risks of neurodegeneration. I REALLY hope I’m right. Next month I’ll be telling my neurologist all this and hope that he will support my logic and my choice 😅
What if kissing evolved as a means to colonize each other with microbiomes?
Mind-blowing
it definitely transfers sex hormones
Are you serious?
If it was we'd all have ulcers
Good point. I think it is rather naive to think any behavior we do is NOT being driven by microbial need. I think it is rather obvious the oldest parts of the brain are the ones responsible for the most basic of human functions. They house the original microbes. The pecky order flows from there.
This is a topic that means a lot to me since when I take a probiotic it really helps my mental state & I have tried to go some time without them & I just don't feel as well.
A possible use for this research could be future space travel in which some humans are almost germ free but that sounds like something we would need way down the line
For those who are interested in this topic, I'd recommend the book "I contain multitudes." I'm going through it right now and it hits on all of the topics in this video and then some (like, for instance, how cows and other rumanids need their microbiome in order to actually digest their food). It's also pretty fair about what evidence on the impacts of the microbiome are more "certain" or more speculative.
I already knew that microbes in my guts have some impact on my brain, but didn`t exactly knew what and how they cause. Thank you for explaining this to me. And especially thanks for the host, whose voice I can listen whole day.
Of course SciShow would be super beneficial to my dissertation work. Thank you.
Thanks Olivia! This is some crazy stuff I want to hear more about in SciShow Psych
What if we aren't controlling us but the little city in us is.. lifeception

Does this mean by kissing someone you become more like them?
If you're kissing their ass,yes.
59acres specifically the anus
59acres Because someone eats your booty like groceries.
It means that if someone vomits in your mouth and you swallow it, you become more like them.
So Rick & Morty got it right.

Putting a literal meaning to the term 'gut feeling'.
I was really stressed to watch this video, during that day this video was uploaded. This is really amazing!
Given that everyone in my family from my Dad on down- I don't know about his siblings or parents except that his mother had many of the same health issues I do- has IBS/food sensitivities/fodmap issues, this is a VERY important topic to me. If there's a way to tweak our systems so we react less to foods that would help all of us. Especially me, since I have the worst of it- the inflammation and blood sugar issues from our normal diets contributes to pretty much every health problem I have aside from the inability to sweat normally that my sister and I were born with. Anything that would let me lose weight, somehow fix the hypothyroidism, help me to get my blood sugar under control, make my mental illnesses less serious, and cause my stupid asthma to tone it down to what it was when I was a kid and I could still go hiking and ride my bike as far as I wanted to would be an absolute Godsend.
Have your doctors ever considered a decade transplant?
@amberkat8147 This is going to sound way out there but aside from all the info about chemicals, bacteria and such there is one thing no one is talking about. It’s the mysterious interactions that happen inside the tiny spaces between the neurons. Called the synapse, this space could be infused with a calming power that can cause dramatic positive changes in how you experience your life. For example, if you could optimize both your head and gut brain together you would find huge improvement in your mental health. Let me know if you’d like to know more.❤
This is a super-interesting and extremely well-done presentation. I have just gone through an entire course on the microbiome on the edX platform which I think is rather boring in comparison. Thank you very much and keep up the fantastic work!
This is the most interesting i have ever seen by you guys. This might have confirmed a lot of my own thoughts and observations.
This is deeply fascinating. It kind of makes me wonder if an individual's microbiome is involved in the cluster of information and conditions we refer to as wisdom.
Have to study for something completely diffrent, yet here i am.
If they want to learn more, they should study me. I've always felt blah. I've drank heavier over the years to the point my gut was getting really screwed up, to the point where eating soluble fiber was a major problem while heavy drinking. When this happened, and I ate something with simple sugars, I had the greatest highs and wish I always felt like this. It wasn't a sugar high, I never had a crash and was wondering how I could always feel like this. Hapiper and more confident. Anyways, I would have to go to a clear liquid diet to let my gut heal.
Wowowowow your speech has improved so much this was a joy to listen to! Well done
Great video!
I don't know if anyone has tested this, but could the reason the mice were getting more stressed be because their gut wasn't creating as much seratonin, due to the reduced variety of gut microbes? I didn't read the paper, but it seems plausible to me.
Does anyone know how to get into this type of research? What do you need for that? What kind of studies you need?
Robert Opran Biochemistry. Biology.
thank you.
study a subject called microbiology. Or just biology. Actually, you can study pretty much any of the basic sciences and still get into this research because its all interdisciplinary nowadays
Strains of Bifidobacterium, which is common in the gut flora of many mammals, including humans, have generated the best results so far. Cryan recently published a study in which two varieties of Bifidobacterium produced by his lab were more effective than escitalopram (Lexapro) at treating anxious and depressive behavior in a lab mouse strain known for pathological anxiety. Although Cryan is optimistic that such findings may point the way to the development of psychobiotics, he is wary of hype. “We still need a lot more research into the mechanisms by which gut bacteria interact with the brain,” he says.
www.scientificamerican.com/article/mental-health-may-depend-on-creatures-in-the-gut/
A decade ago a research team led by Nobuyuki Sudo, now a professor of internal medicine at Kyushu University in Japan, restrained germ-free mice in a narrow tube for up to an hour and then measured their stress hormone output. The amounts detected in the germ-free animals were far higher than those measured in normal control mice exposed to the same restraint. These hormones are released by the hypothalamic-pituitary-adrenal axis, which in the germ-free mice was clearly dysfunctional. But more important, the scientists also found they could induce more normal hormonal responses simply by pretreating the animals with a single microbe: a bacterium called Bifidobacterium infantis. This finding showed for the first time that intestinal microbes could influence stress responses in the brain and hinted at the possibility of using probiotic treatments to affect brain function in beneficial ways. “It really got the field off the ground,” says Emeran Mayer, a gastroenterologist and director of the Center for Neurobiology of Stress at the University of California, Los Angeles.
Searching the internet for Emeram Mayer is a good place to start.
I can see a new field in psychology being formed during the next few years. It'll be called microbe-psychology.
great great information! thank you
this was an awesome video. great job.
does that mean if microbiomes are passed from generation to generation that mental illness in families might not be purely genetic? would be interesting to know. do to my family history.
That had to be a fun grant proposal to review..."Hey Marty, these guys wanna take poop from people and put it up some mouse butts and see if it makes them act funny. They got some freaky scientists over at (whatever university did this study)!!!"
Alexander Cooper they shoved poop 💩 up there butt and then cut the brain up to study it.
......it's a joke
I'm really anticipating more findings because, as a migraineur, my personal experience is one of both brain and gut suffering.
Fascinating, now I want to know more!
In a video about the microbiome the channel What I’ve Learned made, he talks about how certain bacteria might cause autism. He tells the story of a kid who was developing normally, but after several antibiotics courses started acting weird and was later diagnosed with severe autism. Noticing a link between the antibiotics and the sudden autism, the mother dove into the studies and found that antibiotics could cause autism-like behaviour in mice. Antibiotics targeted a lot of bacteria, but not a certain bacterium which was also overly present in autistic children’s guts. So she found a doctor willing to experiment and gave her son a antibiotic targeted specifically at this bacterium and the autism in the kid slowly became less.
I find it very interesting how much your microbiome affects your brain and how it could be the cause of a lot of mental issues. Another example: a transplantation of gut microbiome between two sisters led the receiving sister to become overweight like the other sister, even though she didn’t change her diet or workout schedule.
Future research about this topic really could result in a lot of problems disappearing, it’s amazing
Beautifully stated but the sci show will not look at or address this ground breaking discovery
Uh maybe those mice were stressed out more because they'd been separated from their mothers at birth. In fact I'm willing to bet they didn't even patch up those c-section mice mommas up after their babies were pulled through their abdomens.
yes I have hope now, these studies might help to people that suffers from depression, thank you SciShow, and I am learning everyday
That is super interesting. in Costa Rica, the Bribri people (an indigenous people) believe that you actually do a lot of your thinking with your gut. They believe the stomach and the liver do the same or more thinking than the brain. They have based their ancient medical treatments (based on herbs and different ways to prepare them) on that belief. It turns out they seem to have, at least, a solid ground for that.
I have no brain, though. CheckMate, microbiome! 😁
Memes are like the microbiome of the internet. They are little, they reproduce and they spread inside the guts of the net... and I'll tell ya, they surely affect our brains!
This has been known since the late 90s. memetics Richard Brodie...he also developed the original Microsoft Word...duh en.wikipedia.org/wiki/Richard_Brodie_(programmer)
There's a thing that can happen where yeast becomes a part of your microbiome, and it causes you to get dangerously drunk when you eat too much sugar and simple carbs like bread. It can be hard to diagnose because it's pretty rare, and because doctors tend not to believe the patients when they come to the hospital drunk and say they haven't been drinking.
I have been logging my symptoms with the King's College, London, Zoe app which are front runners in researching the gut microbiome. It's fascinating! I have been logging since it started at the beginning of the pandemic and recently its branched out to other areas of health as it has the largest group of test subjects ever, logging whatever they need. It's a new and amazing way of testing things and of keeping tabs on whatever symptoms each survey needs. It's truly ground breaking and if you can join in the US it's a great way to help scientists and you feel like you've actually contributed.
SciShoe, please do a presentation on the Vagus system. I have just been introduced to it, told it probably figures largely in my mental heatflt struggles.
She looks like amy from big bang theory 😂
lmao fr
I'm glad to see some news about this subject, since I was assuming nothing much was being done about it and would be another 20-30 years before the science and medical community as a whole was clued on to the idea that gut health plays a surprising role in both metal health and physical health.
Right now I have a doctor directed nutrition and diet plan (yes, with probiotics) to help with chronic depression, and I'm making slow but encouraging progress after dealing with it for most of my life. But one thing that seems to keep coming up when trying to get things fixed right has been gut health. Honestly, I've ran into more stuff about the connection between mental disorders and nutrition and gut health than I'd ever care to know.
Shame though, since I know that the big pharmaceuticals (mostly here in the US) aren't going to like the idea that proper food and microbes might actually be the best medicine, and not the drugs they have spent so much money on researching and looking for a use for.
Explains why my depression isn't as bad now that I'm paying attention to my gut health... maybe?
What did you do to change it? And how significant was the change
I'm currently working on this for my thesis and it's really interesting!!
Uploaded just a minute ago and there's already anus jokes
great video, thank you.
amazing video as always
If you're interested in this video, you may also be interested to know that when the gut microbiome is out of balance, it typically has 2 characteristics: low production of butyrate-producing bacteria, and overgrowth of bad bacteria! The more you know!
I have nothing of value to say.
invinciblenoodle don't we all?
You don't need to because you're a valuable person and I love you.
Are you really completely invincible?
If only everyone had your capacity for self-awareness.
Best comment I've ever seen. I'll say that instead of letting people I don't know, know what I think.
Interesting..but I really would like it if they would pitch down a bit and talk more quietly.
Excellent video. Loved it!
This makes for two fecal transplant conversations in a row during lunch today...
I feel that i can relate to multiple parts of this video from being a cesarean birth, and have major issues be bound or restrained. I also can easily adjust to basically any environmental situation or living situation without it becoming to big of a problem. I in fact have a harder time going to a public place than facing complete power grid failure in the u.s. rational? Nope ? Id help it if I can just figure out how. I can relate by feeling mentally terrible when I eat a poor diet. Depressed and lethargic and dim. I had internal chemical burns in the early two thousands and my digestive track no longer works right. When I have a steady intake of live culture yogurt and/ or Keefer, I have a much easier time of life internally and externally.
there she is...
and what about midi-chlorians?
Can we then make a microbiome promoting baby formula to make super children who learn and handle stress easier?
ridjf breast milk actually contains many different oligosaccharides which the baby cannot digest to promote helpful bacteria colonization of the gut by feeding them. Baby formula needs to incorporate those to get close to breast milk.
Dark Rainbow I'm glad someone pointed that out! I wonder if anyone is studying possible correlations between dramatic decline in breastfeeding rates and dramatic increases in mental health issues in the 'developed' world? Probably not as there is no profit in it! Yet it could be one answer to a conundrum of mental health issues in the developed nations.
it's called breast feeding
+Clare Lusher I was thinking something similar. How much does one's diet affect one's mental health or even how one reacts to daily challenges? This entire field of study will likely lead scientists to the conclusion that maintaining a healthy diet is imperative to healthy brain development and maintenance. All these kids who were raised on McDonalds and taught to use these soaps and hand sanitizers that kill 99.99% of bacteria might be so disadvantaged by the negative impact on their microbiome. If you really stop and think about how much you could be effected by poor diet, it kind of puts a lot of things in perspective.
There already IS a "formula" for that! It's called BREAST MILK from each of our mothers! XD
We need to stop trying to create fixes for things, most of our "fixes" lead to more problems. Nature, living by the natural order of our own biology, already has all the fixes! It's because we have moved so far from the natural order of the world that we have so many problems/disorders/illnesses to begin with.
I was a part of a study relating to this research cuz I had IBS...That sounded a lot cooler in my head😬
Speaking of the vagus nerve, you all should do an episode about the vasovagal response. It's interesting how many different things can trigger it.
Great video topic, very intresting, however I'd like to say that:
AS a person WITH DYSLEXIA i FIND it pretty HARD TO read some OF YOUR TEXT in the VIDEO. ESPECIALLY HAVING A smaller font LETTERTYPE which IS still TYPED IN caps.
Easy to read: 7:04
Realy hard to read: 4:28
I can imagen that you do this to make it more clear, but for me it actually worsens the readability.
She is speaking to fast! Neither of my brains can operate with that stress!
These people sound so sure and yet so doubtful at the same time.
Well done!
Always had a gut feeling about this.
I read an article about this from a magazine that just came out this month, coincidence?! Yeah, probably.
I'm going to post the entire article here for anyone interested in it.
"The Enteric Nervous System-Your Body’s “Second Brain”?
HOW many brains do you have? If you answer “one,” you are correct. Yet, there are other nervous systems in your body. One network of neurons is so extensive that some scientists have referred to it as a “second brain.” It is the enteric nervous system (ENS) and is located, not in your head, but mostly in your belly.
It takes an enormous amount of coordination and effort for the body to transform food into fuel. Hence, it is fitting that the brain is designed to delegate, as it were, most digestive control to the ENS.
While much simpler than the brain, the ENS is immensely complex. In humans, it is made up of an estimated 200 to 600 million neurons. This complex network of neurons is built into the digestive system. Scientists believe that if the function of the ENS were to take place in the brain, the needed nerves would be too thick. According to the book The Second Brain, “it is thus both safer and more convenient to let the [digestive system] look after itself.”
“A CHEMICAL WORKSHOP”
Food digestion requires a variety of very precise chemical mixtures produced at the right times and delivered to the right locations. Professor Gary Mawe aptly describes the digestive system as “a chemical workshop.” The sophistication of this chemical operation is mind-boggling. For instance, the intestinal wall is lined with specialized cells that act as chemical detectors, or taste receptors, identifying chemicals present in the food you eat. This data helps the ENS enlist the right digestive enzymes to break the food down into particles that the body can absorb. Also, the ENS plays a vital role in monitoring the acidity and other chemical properties of food particles and in adjusting the digestive enzymes accordingly.
Think of the digestive tract as a factory line managed mostly by the ENS. Your “second brain” moves food through the digestive system by directing the muscles along the wall of the digestive tract to contract. The ENS varies the strength and frequency of these muscle contractions as needed to make the system function like a line of conveyor belts.
The ENS also supervises safety functions. The food you swallow is likely to contain potentially harmful bacteria. It is no wonder that about 70 to 80 percent of your body’s lymphocyte cells-a vital component of your immune defense system-are housed inside your belly! If you ingest high levels of harmful organisms, the ENS protects the body by triggering powerful contractions that expel most of the toxic matter through vomiting or diarrhea.
GOOD COMMUNICATION
While the ENS seems to function independently of the brain, these two nerve centers engage in constant communication. For example, the ENS plays a role in the regulation of hormones that tell the brain when you should eat and how much you should eat. ENS nerve cells signal the brain when you are full and may possibly trigger nausea if you eat too much.
Even before reading this article, you may have suspected that there is a communication link between your digestive tract and your brain. Have you noticed, for instance, that eating some fatty foods seems to improve your mood? Research suggests that this happens when your ENS sends ‘happy signals’ to your brain, starting a chain reaction that makes you feel better. This may explain why people tend to eat so-called comfort food when feeling stressed. Scientists are exploring the possibility of artificially stimulating the ENS as a treatment for depression.
Another example of communication between the brain and the digestive system is what has been described as having butterflies in one’s stomach. This feeling may be the result of the ENS diverting blood away from the stomach when the brain experiences tension or stress. Nausea can be another result, as during stress the brain triggers the ENS to change the gut’s normal contractions. According to experts, this brain-gut connection might also be the basis for so-called gut instincts.
While the ENS may generate such gut feelings, it cannot think for you or direct your decisions. In other words, the ENS is not really a brain. It cannot help you to compose a song, balance your bank account, or do your homework. Still, this marvelous system continues to amaze scientists for its complexity-much of it perhaps still undiscovered. So the next time you are about to eat a meal, pause and think about all the monitoring, data processing, coordination, and communication that is about to take place in your digestive system!"
Thank you
Great job Olivia
Can't think of any jokes, might ask my gut
Sean Ross pulled out the biggest fart ever
Too bad my brain didn't send enough signals to certain parts of me because they are now forever stuck being micro.

Not only Asians have small hands.
KamiltheCamel Ya, you were _totally_ talking about your hands... 😉
Well at least I like to use my hands on it.
KamiltheCamel hey wow
This is so cooool!
Love this topic!
I went to my neurologist a few years ago and asked if my Vagus Nerve could be affecting my Fibromyalgia, Mitochondrial Myopathy, and Traumatic Brain Injury thru my gut. He got really nervous, called his nurse and they took me into his office and closed the door. They asked how I knew about the Vagus Nerve, they were angry, they said I didn't know what I was talking about, and that I should forget what I was talking about. They took me into another office and wanted me to discuss this with another one of the PA's there. I left and never went back. How many physicians KNOW that the cures are easily found - cutting their practices out of the profits to be made. Do I seem paranoid? Not really, just waking up to what the medical "industry" is doing, and how cures are not welcome. I eat my yoghurt, and have increased my probiotics, see my Naturopathic Doctor, and guess what? I'm getting better!
Your story doesn’t make sense at all. You sound like a paranoid conspiracy theorist.
6:19 serotonin produced in the gut doesn't get to the brain I believe. it acts differently in each organ
that is true. The function of a neurotransmitter seems to vary depending on where they are localized to.
Sure doesn't, so unless gut and platelet serotonin is what emotion & behavior is all about.... Also, tryptophan does get to the brain (serotonin precursor), but little/no evidence microbes influence ppl's tryptophan levels.
1:17 mouse mouth lol i love it
Well hopefully we can figure out how to make sure we are getting beneficial things from this microbiome
Nothing about this is weird.
We have always known, "You are what you eat"
those mice must have eaten fecal matter as heavenly possible
I dont remember eating a human
Redstone Pro duhhhh your memory was wiped
Zenn Exile so if I eat pssy then does that turn me into a pssy.
Every single day you consume a measurable amount of human, in the form of hair and skin cells.
So it is not that you don't remember, Redstone Newb, it is that you did not even notice. Because you are a disgusting waste of cognitive ability, and have developed no concept of what it means to have a single perspective, among many.
You kinda disgust me tbh.
As the old saying goes: 'the way to a man's heart is through his stomach'.
Idt it pays homage to pin it down to one detail or another.. IDK all I can tell you is that this is something about you that totally gives me the Amy Farrah Fowler vibe!! And I fking love it!!!! So, thank you for doing this job!!!! I hope you're having a blast as much as I enjoy spectating!!!!!
Great video, glad to be early!
