Do Gut Microbes Control Your Personality? | Kathleen McAuliffe | TED

Biologist Kathleen McAuliffe dives into new research that suggests certain bacteria in your gut can influence major parts of who you are, from your personality to life-changing neurological disorders. Learn more about how this emerging science could change how we treat disease — and discover the impact of your internal microbial makeup on your mood, weight and more.

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

[rdapigleo]

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

[coolbear]

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

[peter_parkour]

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.

[jonatani]

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

[Knowledgeispower]

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.

[coolbreeze]

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

[yoursoulisforever]

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!

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.

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.

[nusu]

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!

[tonyosime]

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.

[ikaren]

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!

[aujax]

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.

[marylamb]

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.

[BandiMuraliKrishna]

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

[MayaLove]

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.

[allisonmcfadden]

You can stimulate your Vargas Nerve yourself at any time by closing your ears with your fingers, deeply inhale, and vocally hum 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.

[michaelhoush]

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

[Taras.Havryliuk]

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