This gives new meaning to having a “gut feeling “ about something.
Oh wow, seriously
It’s like all the microbes convening for a meeting, sending signals to the brain messages of their consensus.
And the 'pit in the stomach' we feel when scared or anxious.
It’s an infectious idea
"You are what you eat" on a whole new level.
also we are what we poo
there is also old beliefs about the fact indirectly claiming that soul of animal you eat live with etc or similar ... also this logic gives a bit more stable and alternatig perspective to soul and ghosts :D
You are what you believe because your cells respond to your thoughts and feelings. Thank you for your comment.
@@ahmetmutlu348 Prove souls and ghosts exist with testable, repeatable, verifiable evidence please. Just an assertion isn’t good enough.
@@kellydalstok8900 well.. i mean the identity of the person when i say "soul" ... or the thin representing it.. or its deology... which may mean same thing ...;)
logically what we can prove is that we know there is something that feells .. bu what it is , is anoter question... and yeah i agree that there is mostlikely no such thing as transparent beings... i think soul i part of universe but its not verifiable. what we know is memories that define our identity define for us who and wht is good or bad... and memories are part of body... so mostlikely not part of soul... which itself clears lots of questions ;D and this research/experiment indicates part of memores ie good bad definitions are not part of brain ...which is definitely rule changer ewen for that perspective .. :)
I'm now wondering if the majority of the people in the world are experiencing this kind of messed up gut leading to all the depression and anger and stupidity in the world especially here in the us where the American diet is the worst of the worst. Full of toxins and all kinds of crap in our processed food and water. Interesting don't you think?
We need more studies on this
Makes you think that the epidemic of anxiety and depression is not just “the economy” but actually gut health problems.
💯
@@ThrobbingBox also babies in crèche from X months old because parents are forced to both be at work full time
Totally! Looking into these things could be soooo beneficial! For example, maybe an abundance of toxin A builds up in the region of the brain responsible for mood regulation (i.e.- anger) so the people who ingest toxin A are more prone to criminality. So instead of dosing them with meds or labeling them with a mental illness, they could just stop ingesting foods containing that toxin. Eventually their brains would re-regulate.
^ yea? ❤
Who do u mean by depression and stupidity lol?
TED, please add affiliation of speakers in your video description in youtube then I can further follow their studies, activity and so on
YES
She has a book, and I’m sure sources will be listed there. Definitely checking it out. Other gut doctors have also made videos on the microbes in our gut! Check out Dr. Will Bulciewicz.
Couldn't agree more
Just type her name into Google...? Her book, this video, and her website are the top 3 results. Not far down the results is her intro page on the TED website as well.
yeah geez Ted act academic why don't ya?
I am so convinced the power of the gut. I have seen a friends son who suffered from major learning disability change completely with gut bacteria treatment. He went from barely reading to a normal happy kid. We really need to dive into this field. Instead of pumping more pharmaceuticals.
What treatment did he recieve?
@@Reme873my guess, I’m not the original poster, but fecal transplants have proven to have great lasting effects.
Besides, it is quintessentially necessary to modern Western society to have something-anything-to blame for whatever is happening other than ourselves. “Our culture peculiarly honors the act of blaming, which it takes as the sign of virtue and intellect.” -Lionel Trilling
Big pharma won't like that
Centuries ago, Hippocrates said all diseases start in the gut. Doctors didn't pay attention?????
This explains why I felt so weird after coming off of antibiotics after I got an infection 😭 Mood swings, felt awful, critical thinking was shot, and just lethargic for weeks after recovery.
They usually prescribe probiotics along with antibiotics now--even for my dog when she was on them.
Centuries ago, Hippocrates said all diseases start in the gut. Doctors didn't pay attention????? Did you get your 80th boo ster yet?
That’s interesting I have just had a course of antibiotics and I have had the opposite reaction not feeling depressed memory had improved energy levels up, but I ate some red meat and my gut just about exploded this Ted talk and your comment have really got me thinking.
This is why the gut should be examined first before pushing anti-depressants on people
That would be amazing but I'm not sure if it's that simple to fix dysbiosis. At least not yet. I have had tests showing that my gut microbiome is out of whack and have worked for years with doctors, (traditional and integrative) trying to get it back in order to no avail. No fix ever lasts. This research is promising but still in the early stages. Hopefully, science will lead us to more options for effective mental health treatments through balancing the gut microbiome.
dont mess with big pharma.
@@kitcat178what kind of treatments did you go though?
@@mrchristian87 Two rounds of xifaxin for SIBO. Low FODMAP diet, Low fermentation diet, Fast Tract Diet. Pre and probiotics based on GI map results.
Amen and environment stress cues
Saw this and immediately ran out in the street shouting, "I'm in control here!" Seriously thought, I think this video deserves a big thumbs up!
That was you? I wondered who it was 🤔🤭.
I had severe depression but I went to a Chinese doctor. She traced it to bad gut bacteria by asking a few questions about my diet. I took antibiotics to kill bad gut bacteria and have never, ever had depression again.
I just finished an antibiotic treatment for hpylori and I never felt so much better! I’ve had brain fog, constant headaches, bloating and GI issues. This caused me anxiety and depression for years!
how do you get that
Yes Helicobacter Pylori, I was treated 20 yrs ago and feel great. I also now consume yogurt and a variety of fermented foods, never felt better.
Please enlighten us too. My body is a mess and I recently became disabled due to it. Could really use a gut overhaul
A naturopath can run a G.I. map which will test for about fifty possible issues in the gut at once. That’s how I finally found I had an h pylori infection. Completely cured all insomnia after antibiotics.
Well antibiotics can do harm aswell🥲...so it's a complicated matter
0:23 🦠 The human body contains microbial tenants, collectively known as microbiota, which influence various aspects of our health, including digestion and even mood.
1:50 🐭 Bubble mice raised in sterile conditions without microbes display behavioral differences compared to normal mice, indicating the impact of microbiota on behavior and learning.
2:20 🤝 Gut bacteria can influence body weight and mental health; transferring bacteria from overweight or depressed individuals to mice can affect the animals' weight and behavior.
3:31 🧠 Gut bacteria communicate with the brain through psychoactive compounds, neurotransmitters, and the vagus nerve, influencing mood and behavior.
4:45 ⚖ Vagus nerve stimulation (VNS) therapy, approved for epilepsy and depression, may strengthen the gut barrier, preventing inflammatory responses that could affect the brain.
5:39 🩹 Microbiota-based treatments, targeting the gut bacteria composition or their chemical actions, show promise in addressing mental health conditions like ADHD, OCD, PTSD, and autism spectrum disorder.
7:09 🦠 Certain bacteria are linked to neurodegenerative diseases such as ALS; researchers have identified bacteria that both accelerate and slow the progression of ALS in animal models.
7:58 🧬 The misfolding of the Parkinson's protein, alpha-synuclein, may be linked to a strain of E. coli in the gut; understanding this connection opens new avenues for intervention in Parkinson's disease.
9:29 🌐 New insights into the origins of diseases like Parkinson's offer potential for developing interventions, sparking optimism in the medical community.
10:02 🤯 The person's behavior is influenced not just by the brain but also by gut microbes, emphasizing the interconnectedness of the microbiome with overall health.
For someone with ADHD, thanks for this super helpful breakdown.
I watched the whole video, but I LOVE having your helpful notes to summarize it. Thank you!

following the topic for years, i wonder when it finally will become a therapeutic option specially for psychological deseases. Hope i will live long enough. Thank you to the scientists for this awesome work!
and me i had 30% kidney failure went and sorted diet out fine now see what happens the next 10 years they had me down for RA etc etc
Many biological psycho therapist are now prescribing different types food/diets for MI
When conventional Med schools start teaching nutrition as the foundation of health, we will see a change.
I am NOT optimistic!
í guess it depends on the country. if you are talking about the US, you might be right @@jld4870
Check out Living well with Schizophrenia. She is in youtube and has changed her mental health with the keto diet.
It’s a shame she didn’t talk about what we can do to improve our gut health as it is certainly in our own hands via nutrition! That’s available right now.
She did a little. Yogurt
Eat a farm fresh organic balanced diet, drink raw milk, and consume turkey tail mushrooms

TED speakers have a limited amount of time to talk. You can Google her to find more of her work where I would imagine she goes into more detail and solutions. There's also an hour-long video from her... I'm sure there's more videos.
Carnivore is the answer to gut problems
"In the symphony of microbes within, our 'I' emerges as the harmonious dance of 'We,' orchestrating the unique melody of our shared existence."
Directly related to the food we eat and how that food is grown. Period.❤
I discovered this idea 3 years ago through the GAPS diet. I still follow most of its principles but have switched to more vegetables than meat. It has helped my autoimmune disease, eradicated all seasonal allergies and helped temper my mood swings without a single medication. I am so glad this is being discussed in the mainstream now.
It really does not take long to make fermented vegetables, sourdough bread, meals from scratch if you plan ahead. Couple that with rarely eating out and altering your skin and beauty products, you will be on the road to health. Food IS medicine.
One caveat: this is an expensive way to live but would you rather pay as you go and enjoy the benefits or pay the medical field to experiment on you and languish in a hospital?-- to put it crudely.
I am shocked. Thanks a lot for this TED. It was very exciting.
very powerful presentation skills and great content, well done
Thank you Kathleen and others for all your work on this. This makes me wonder if one time we get food poisoning, if it could lead to that domino effect? The general public needs more information about all this and what if anything we can practically do to try to prevent severe outcomes.
Ted Talk improves my English level.
Thank you for providing interesting videos:)
For me, this video only showed how low my level is
The s should be after "talk" like this, "ted talks improve my english." ;) unless you mean this one specifically, in which case it would be, "This ted talk improves my english." Good luck!
was probably a bot learning but love your enthusiasm to teach. @@huy2496
Outstanding and brilliant talk! Thank you,
Fantastic talk! So glad to hear about the research. It makes me wonder about some of the more rare mental illnesses like bpd.
OK, so this is fascinating - but presenting this information without any insights on how to improve "good" gut bacteria is frustrating. Should we all be taking probiotics?
Exactly my thoughts too!!
Just eat Yogurt and Kimchi daily, it’ll do wonders for your gut microbes.
@@pattibase2293 when have throughout human history did we regularly take probiotics? Probiotics are pointless if you need them that means you have a problem thats preventing microbes in general and probiotics from reaching the desired place. Poor dieting causes this stuff and a healthy diet/lifestyle fixes it
@@starc. Your first dose of microbes is when you’re born (naturally) and through breast feeding. Fermented food has been around for thousands of years and was used to store food and it’s a great source of microbes. A lot of foods in the grocery store though have been irradiated to control food borne illness, unfortunately it kills all the good microbes too. I agree that a healthy diet is great but the added boost from fermented food is backed up by quite a bit of recent research. You can find it with a quick Google search.
@@starc.this sounds right to me but the money machine has to keep turning and people love a medical intervention!
Great topic coverage
Great summary, been looking a lot into this recently.
Fascinating Conversation 💡
EXCELLENT TALK!
I started talking a good quality probiotic about 5 months ago.
It has made a huge difference in my tendency to depression.
You can stimulate your Vargas Nerve yourself at any time by closing your ears with your fingers, deeply inhale, and vocally hum “Ommmmmmmmm” going up and down in high and low pitch, experimenting and feeling the sound going up & down your Chakra energy system and Vargas Nerve until you run out of breath, even making vocal noises like Tibetan Monks do in your throat using your tongue, using your own tonal sounds. This has been done for thousands of years. Try it in sessions of 3-5 minutes at a time and see how your body, mind and spirit feel afterwards. Be your own scientist and healer. I appreciate this video, the scientific study, the sacrifices of mice for our learning, and scientists while adding there are additional approaches involving consciousness that conventional science can leave out of the puzzle. We’re not victims to genetics and outside forces unless we believe we are. We must go deeper and excavate to see what’s true for each of us based on belief. Thank you.
we means less I...add loving-kindness & we're on our way to being Bodhisattvas!
Plants too have their root microbiomes and the resilience of plants to climate change can be fortified by inoculating beneficial microbes to root microbiomes.
Thank you 🎉🎉
This is probably the most interesting Ted talk I've come across. I'm obsessed with her fluency. I understand everything she's saying. And I'm actually directly dealing with this on my own. I was wondering why my fridge is filling with greek yogurt. And even studying the lesser known Vegas nerve.
I have known this for years, my microbiome has huge influence over me 24/7
Have you seen good changes in response to taking up probiotics?
Please, tell me how to fix it.
To enhance your gut microbes simply apply the proper diet. No carbs, zero sugar and absolutely no plants. Yes, NO plants. Plants (most) contain oxalates, these oxalates are not meant for human consumption. Look into the carnivore diet. Dr. Ken Berry or Dr. Anthony Chaffee. The carnivore diet completely changed my life. I highly recommend looking into it.
@@charleyarchuleta4932I take probiotics that contain (lactobacillus acidophilus, lactobacillus rhammnosus, bifidobacterium longum, bifidobacterium breve, bifidobacterium bifidum and lactobacillus lactose in one capsule per day within my diet). These fellas have been great with my body and since I have autism, eczema and Allergies, they have been essential for me.
@@charleyarchuleta4932 there is no point in taking probiotics because the very thing causing a microbiome problem that you drink the biotics to fix is causing the probiotics to never reach that spot in the first place
Wow 😳🤩!
Kathleen McAuliffe`s lecture is an eye-opening experience for me and, perhaps, points the way to the right direction!
I truly hope that the outcome of further/ future studies and researches will at long last the game changer so many affected people and all scientists around the world hope for, as solving the mysteries in links between all bacteria, microbes etc., living in the human body, may hopefully lead to a world at peace!
Best of luck and success!

Great talk!
Expertly delivered 🙏
Gave my wife shirota bacteria and reuteri because she was in really bad shape. Changed mood and physical activity very quickly. About 3 days after years of suffering.
Can you name the brand?
"Bubble" mice are an interesting concept. Could some of today's kids be nearly "bubble" kids as regards naturally bacterias? Have limited diets and ultra-sanitized environments caused mental illnesses in young kids? Is lack of contact with soil something we should look into, to make sure kids literally "touch grass"? Lot of interesting extensions off of this topic.
Yes I have noticed so as well
Very true. But I do all that for my kids they are still sick every month. lol
A study from Switzerland conducted several years ago revealed a link between the lack of exposure to various microbes during childhood and an increased risk of developing different illnesses. In other words, children in Western societies live in excessively clean environments.
I've also noticed that children today are more prone to allergies and other illnesses compared to those from a few decades ago.
literally touching grass more would be the worst way to fix possible problems caused by lack of biodiversity. you dont know whats in the soil. it may do nothing for the problems you're experiencing or end up giving you more problems. our best way forward is to learn exactly what bacterias do what and then isolate them to make therapies specific to the problems people are having. you shouldnt carpet bomb your immune system more to possibly aquire a benifical bacteria.
@@paulatreides6779 yeah that's probably because most of the kids with serious food allergies just died young. the increase in people with issues is because the threshold for survival got easier. moving backwards isnt going to fix these issues. it'd likely just lead to more kids dying.
Thank you. This is exciting and sounds very promising
You're amazing and doing amazing work
This is a really fascinating topic as it seems very un-intuitive to me. I wish there were links to some accessible review articles covering each of the mentioned findings. When I search for such things on my own I seem to find either vague popularizations written by people who don't seem to understand the topic, or extremely specific, primary research articles with a minute focus, that speak in dense jargon and lack a big-picture view of the larger topic.
wow, this helps open the box to my own symptoms since I've had H=pylori. I've really slowed down mentally and emotionally. I'm also dizzy all the time.
You can try reading Dr. William Davis's book "Super Gut" and make his l.reuteri yogurt. L.reuteri can eradicate h.pylori.
Good start
“You are what you eat”
This is so interesting!!
I've suffered from chronic I.B.S., anxiety and depression ever since I came home from over seas "Iraq"....
This really makes me want to get someone healthier and transfer thier gut bacteria to mine....
Probably those MREs with their preservatives messing with your gut.
@1:00 YAY 😍
Just Thank You.
I believe it has been widely recognized for quite some time that the bacteria in our gastrointestinal tract can influence our brain and emotions by modulating hormones.
So true, I don’t understand why this information is not ubiquitous… ❤️🌱🌱🌱
good speaker💐
Yep, they do influence it
You only mentioned drug Solutions I really expected you To talk about how our food choices Could also Reverse Disease issues Like Ultra refined Foods especially carbohydrates
Had i gone toward an MD/PHD 10 years ago - this is exactly what i had said i would study.
I was interested by the idea that bacteria cause mice to seek out cats.. and came to the hypothesis we may have similar reactions.
Good information.
love this.
She has a relaxing voice
Fascinating
It would have been nice to get specific bacteria / chemicals /neurotransmitters mentioned
In ayurvedic treatment there is a great emphasis on gut cleaning and rebuilding stomach microbes with herbal remedies and food.
I frequently suffer from the hiccups and bacteria play a great role in that. Can it lead to more serious issues if treated with only antibiotics?
My own story goes: I worked for a paleo restaurant for a few years and also dated a guy who was gluten free at the same time so I just naturally stopped consuming gluten and I had already stopped eating dairy bc I figured out I was (still) allergic to it.
Once I stopped dating the gluten free guy I started dating a guy who had no restrictions so I started eating gluten again bc I thought it was fine for me but it absolutely was not. Not only did/do I get TERRIBLE gastro issues if I get even so much as a crumb of gluten (these days) but I also figured out that it literally gives me "mood swings" or at least makes me MUCH quicker to rage and at veritably anything. I felt like I wasn't myself so I stopped eating it and never went back!
It all goes back to Monsantos anti bacterial weed killer and the various effects or ag practices like using animal waste then it all gets in the river and bacteria with resistance thrive
Sophie Strand is saying this for years! Her work is also amazing
Let's gooo! Really exciting findings
Yes all true
Our mind is just a pattern storage and recognition organ. It compares input patterns (sensory perception) to stored patterns (memory) and calculates likely outcome patterns (thought).
This is the you that you think you are.
The gut feeling (emotion) is just an older internal operating system closer to the one used by your organs.
Think of your organs as separate organisms, they like and dislike things just like you. They actually have authoritative control (emotional irrational behaviour, fight or flight)
Your mind was developed to protect and provide for the body of organisms (organs and their inhabitants) you are their interface with the outside world. you are their ruler but they can be unruly if you mistreat them.
I've heard there are ways to naturally stimulate the 'Vegas nerve' without the need for external devices... I'm not saying the device route's bad/wrong, just that there are alternatives that are easy to do at home (including humming, breathing deeply, & other simple, relaxing techniques)
You are correct.

Gut-Mind blowing information.. 🎉 Thanks 🙏
serious question here , Given the gut affecting our character, and personality , IS there a relationship between the plastic and chemicals we subject ourselves to in a door polluted diet ?
There's some interesting research on the interactions between LSD gut bacteria and also brian amoebas. To bad were 75 years behind where we could be.
I've been trying to tell people this for ages!
Great talk...thank you Kathleen.
so what is the recommended diet or supplements?
Furturoma had an episode on just this subject.
Good job.
brava, chiarissikma.
"We" are intrigued...
I see what you did there 😁.
Recent studies suggest VNS therapy to be ineffective.
Paleobacteria is of interest to me in Addiction disorders and Alcoholism. Nutrition based recovery from these diseases is possible and practical. The microbiome do for us what we can not do for ourselves. On a not so different topic, it is my belief that cancer and heart disease and depression and diabetes and obesity (to name but a few) are in-fact contagious.
What bacteria molecule is she referring to which can cause anxiety in people with Autism? Inflammatory cytokines?
Welllllll.....We've long used the expression "I don't know. I just had a gut reaction" or "a feeling in my gut".
I struggle with autoimmune psoriatic arthritis and debilitating depression. What if it is all based in my gut microbiome? How does one radically alter it?
they do when i'm alone.
I had abrupt personality changes after using Wegovy to control appetite. I had several digestive changes and discomforts, I wonder if it's related.
I had to stop the medication.
Yes they do..... Some of my pets got worms and acted different... Until I medicated them and returned to normal
fascinating... that old saying "you are what you eat" springs to mind...
I'm glad this is finally getting attention. I've known this instinctively since I was a kid. I never took antibiotics without a real need (i.e. death) and did my best to avoid toxic foods. Look at the rates of C-sections that deprive the newborn of the initial inoculation from the vaginal canal. Consider the volume of herbicides and pesticides dumped onto our farmland to kill life; the same life found in our gut. Look into the drastic changes in kids who receive unprocessed, real food for the fist time. Sterile food full of preservatives does nothing for you. If it wont go bad on the shelf, it will not feed your micro biome. Think of how much money the pharmaceutical companies have been making selling the poison they put on your food, selling farmers the seed that the poison is applied to, then selling you a pill to "fix" all the problems it has caused. Eat real food, not processed poison.
fascinating
Reminds me of the research by the University of Aachen on how trees 'talk' to each other. Think this lead to the cutting down of a large area of woodland to make way for the building of a wind farm, because they overheard the trees were climate change deniers.
😂that kind of talk spreads
With the talk of interfacing the mind with computers or downloading the mind , what wou,d you get without the microbiome. Would,d you get a depressed sluggish possibly insane version of the orimind ?
This is interesting because I've observed very different behaviour patterns according to people's eating habits....
Very interesting - following
Is the malfunction of these bacteria caused by eating food covered with pesticide and herbicides? It will be a long time before the regulators allow this to be found out I think, but there weren't so many people with "divergent neurological" conditions years ago when all food was organic
What we eat or ingest matters far more than initially understood. Food is either medicine or a slow poison. Clean water and air also have a massive impact. We have the biggest impact on what we eat. It's one of the few things we have FULL control over. Choose wisely. Moderation in everything.
Is there a website where a person can become their own health care practitioner?
Satnaam ji, that’s why in India there is old saying, “as is the food as is the mind”
Can some tell us what to do?
My father died from Parkinson's so this is exciting news to me. On the other hand it is also kind of scary that so many of us are oblivious to potentially deadly diseases caused by something we don't even know we have. 😮
Amazing
I am reminded of that scene in the movie “The Alien” where that freaky thing popped out of the guy’s stomach!
