  • "Have you ever had a gut feeling or butterflies in your stomach? Has hunger ever changed your mood? Our bellies and brains are physically and biochemically connected in a number of ways, meaning the state of our intestines can alter the way our brains work and behave, giving a whole new meaning to 'Food for thought'. As a nutritionist, microbiologist and neuroscientist, Ruairi Robertson is passionate about the link between our bellies and brains. His research is examining how our intestines and the microbes within them can influence both physical and mental health, and most importantly how our diets influence this relationship. Ruairi has travelled the world researching food, and believes it is the key to global public health. Ruairi is a PhD student in University College Cork in Ireland and current Fulbright Scholar (2015/16) to Harvard University. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at

    I agree with this 100% this supports the conclusion I've come to recently just in paying attention to how my moods have changed since I've become vegan. I notice when I eat junk food like mass produced pizzas and fried chicken I get in these really depressive moods and anything can tick me off, I also notice I get really depressed when I'm constipated. But since I've changed my diet I feel happier less irritable. I figured that my what I'm eating must affect my moods somehow, so happy YouTube suggested this to me.

    Incredible research, I'm so fascinated! I recently started eliminating sugar and adding healthy fats to my diet and instantly noticed a decrease in my stress levels and increase in mood. I think my gut thanked .e with some seratonin. Phew!

    We are all aware that we have bacteria in our gut and through out the body, but I never realized it was a 9:1 ratio (9 bacteria to every 1 human cell). I also never considered how much what we eat can affect that bacteria, the bacteria affects not only our digestive system, but also our brains and the way we think. It surprised me that there was enough of a connection with the gut and brain that it can actually produce serotonin to create either depression (a low level of serotonin) or anxiety (a high level). And that if we are noticing symptoms we can correct them by eating more starch (to decrease serotonin levels by 10%), or eat more protein (to increase serotonin levels by 35%) for breakfast. This video makes you think of what your body and consider that the food we eat alone can affect our moods, digestive system, and even personality. This was very informational and interesting considering how much what we eat really does have an impact on us in many ways.

    I can definitely see how taking care of my gut health with my natural supplements, eating habits, and exercise has directly contributed to how I've felt, behaved, and and even thought these past five months. It's been an amazing journey and I feel like I'm just getting started!

    Huge implications for mental health. Probiotics and better diets instead of antidepressants!

    Beyond being one of the best TED ever, this TED gives the answer of life. It tells to take care of your stomach so not drinking, eating well, sleeping well and more importantly HAVE A GOOD POSTURE. Because posture can block your diaphragm and we know that diaphragm massages the stomach. Take care of your body and enjoy your life

    Ayurveda, the Indian traditional medicinal system has always talked about the gut being a central pillar of human health (mental and physical). This is just one more validation for it from the western science.

    I had to have a c section unfortunately. As I was aware of the microbiome I did a swab so that we could rub as much bacteria over our baby as possible. The hospital were totally against this as it was unheard of but we pushed it anyway and signed a waiver (just saying if anything went wrong it was on us). After that more of the Doctors and Nurses there actually looked into it and are now much more open minded for others who may want to do this in the future :)

    Depressed, and having studied taoism and buddhism, I asked myself, 'since I am not thinking bad thoughts and nothing bad has happened, not only why do I feel depressed, but where is this depression'? I wanted to see if I could point to the feeling. It was then that I noticed it was a vague feeling in my gut that resulted in my sullen mood. In fact, once I leaned to the side and belched, my emotion changed. This may sound silly, but I have other examples as well and am now intricately more aware of my gut. I have successfully helped myself with intermittent fasting, though I have not altogether alleviated sadness, which is largely linked to being alienated from my children, and to my subsequent realization not only of human nature but also to our system of governance. But, to what I can control, is where I will ultimately hope to focus. Great Ted Talk.

    I truly do believe that this almost conveys what our grandparents were always trying to teach us. But, somewhere along the line, but, we missed the point. We do need to get back to our basics. I truly believe that this is a great reminder of that way of life.
