This gives new meaning to having a “gut feeling “ about something.

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.

TED, please add affiliation of speakers in your video description in youtube then I can further follow their studies, activity and so on

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

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.

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!

"You are what you eat" on a whole new level.

This is why the gut should be examined first before pushing anti-depressants on people

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!

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!

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.

"In the symphony of microbes within, our 'I' emerges as the harmonious dance of 'We,' orchestrating the unique melody of our shared existence."

A great talk. I make my own fermented vegetables (with over 60 varieties) and eat about 2 small cups a day in 2 sittings. I have not had or needed antibiotics in 4 years. My approach to eating is to feed the gut. I make sure every meal has something for my gut microbes. I do not remember being healthier in my life. I can confirm the impact on personality. I realise now that I used to be grumpy without knowing why. Now I seldom get upset and marvel at how relaxed I am compared to my old reactions. My next stage is to pay more attention to my microbiome signals.

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.

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.

Directly related to the food we eat and how that food is grown. Period.❤

when i get thru a week or so on a ketogenic diet, i feel like a different person (which changes the microbiome) i become more calm, upbeat, less irritable, more clear-headed. removing sugars, wheat, rice and potato (or any carbohydrates) seems to shift my mood in a positive direction.

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.

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:)

I am shocked. Thanks a lot for this TED. It was very exciting.

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?

very powerful presentation skills and great content, well done

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.

"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.

I have known this for years, my microbiome has huge influence over me 24/7

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.

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!

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.

Plants too have their root microbiomes and the resilience of plants to climate change can be fortified by inoculating beneficial microbes to root microbiomes.

She has a relaxing voice

Fantastic talk! So glad to hear about the research. It makes me wonder about some of the more rare mental illnesses like bpd.

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.

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

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....

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.

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

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… ❤️🌱🌱🌱

Outstanding and brilliant talk! Thank you,

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!

A list of sources, papers, studies referenced in the talks would be helpful

I started talking a good quality probiotic about 5 months ago. It has made a huge difference in my tendency to depression.

good speaker💐

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)

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.

I've got the guts to do anything now! Thanks gut bacteria.... Thanks...😂

How sad knowing that animals are so smart and yet we take advantage of their inability to defend themselves to experiment 🙁

Fantastic. So lactobacillus is what we should try and elevate to balance our moods?

Great summary, been looking a lot into this recently.

so what is the recommended diet or supplements?

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.

"We" are intrigued...

I developed gastritis and depression right after losing my parents, I wish I had known about the stomach and brain connection, I wouldn’t have suffered the way I did. Whenever my stomach doesn’t feel right, I become sad, once my stomach feels better, I’m happy again. Everyone should know this.

Who knows what we'll discover about our bodies in the future! There's still so much we have to learn. Who knows, maybe my thoughts are the bacteria thoughts!

This has become my Roman Empire

Is there a website where a person can become their own health care practitioner?

Great topic coverage

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.

Expertly delivered 🙏

Yep, they do influence it

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.

Furturoma had an episode on just this subject.

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 ?

You're amazing and doing amazing work

Sophie Strand is saying this for years! Her work is also amazing

Yes they do..... Some of my pets got worms and acted different... Until I medicated them and returned to normal

EXCELLENT TALK!

I've been trying to tell people this for ages!

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.

Micro biome be like, I told you not to drink alcohol at the party, but micro biome be like I am the party. Micro biome, be like how can I explain fish and chips to the rest of the world without all that gas?

fascinating... that old saying "you are what you eat" springs to mind...

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.

does this mean that eating psychoactive mushrooms could permanently alter personality for reasons other than the psychedelic experience itself...?

Welllllll.....We've long used the expression "I don't know. I just had a gut reaction" or "a feeling in my gut".

I am reminded of that scene in the movie “The Alien” where that freaky thing popped out of the guy’s stomach!

I appreciate this.

Satnaam ji, that’s why in India there is old saying, “as is the food as is the mind”

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.

It would have been nice to get specific bacteria / chemicals /neurotransmitters mentioned

Gives new meaning to “My name is Legion, for we are many.“ … maybe it was a gut bacteria thing?

Fascinating Conversation 💡

I often think of this with fungi. Are we the things raised and farmed?

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.

What bacteria molecule is she referring to which can cause anxiety in people with Autism? Inflammatory cytokines?

Thank you. This is exciting and sounds very promising

The more I hear about the gut, the more I think we need to change how we eat. All this processed food is killing us. Big Food and the usual combination of greed and money and power.

Each of us is a system. Good that western science started seeing this even now.

Could certain microbes present in dogs cause behavioural changes in humans once they enter the human’s digestive tract? This would support my theory and explain why dog fanatics engage in high-risk/self destructive behaviours, such as venerating and glorifying the ownership of an unpredictable, remorseless, bloodthirsty predator (dog) which is responsible for over 28,000 reconstructive surgeries every year in the USA alone and 30-50 deaths per year in the USA alone, transmission of zoonotic diseases, destruction of property, creation of noise pollution, violence between neighbours, ruining of relationships, pollution of our water, etc. Someone please research this! The behaviour of dog worshippers is exactly like the irrational, self-destructive behaviour you see in animals infected with mind-controlling parasites.

Great talk!

Excellent findings! Now. Who’re working on reviving the small intestine and putting celiac disease into the pages of history?

Thank you 🎉🎉

This is interesting because I've observed very different behaviour patterns according to people's eating habits....

Recent studies suggest VNS therapy to be ineffective.

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?

The vagus is the vaguest nerve in the body.

Why am i reminded of Severus Snape?

These days, everything controls you - but you.

Good information.
