  • "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.

    Ditch meat, dairy, and eggs completely. Good gut bacteria proliferate from plant foods which promote health; while bad bacteria proliferate from animal foods promoting illness.
    Improve your health, protect our environment, and increase your humanity towards animals by going vegan.

    Actually not only microbes in intestine, but the secretion power-absorption power, activity of intestine is also the base of physical and our mental health. It is said in Ayurveda and since thousands of years Ayurveda doctors are using this fact in the treatment of bodily and mental disorders. Its just we neglect our ancient knowledge and wisdom and call ourselves modern..!!

    I loved hearing this scientific explanation of the Biblical phrase, "bowels of compassion." It always sounded very odd to me, as a young Christian. Now, it makes perfect sense! Just like when it was declared in the book of Job that God hung the sphere of the Earth on nothing long before anyone had scientifically posited the possibility of the Earth being a sphere.

    so much information eat dont eat, fast dont fast, skip breakfast, eat one meal a day, avoid grains, then eat whole grains, go vegan then dont eat vegetables as plant based diets now cause dementia.
    eat only carbs in the evening or eat only vegetables yet they are spayed with more chemicals just like food is pumped with chemicals best not to eat anything.
    we will end up vitamin deficient so now being over weight is better as we get older to avoid the diet face and nutrient loss face. I have heard so much information I find it fascinating with these anti ageing creams they have today I would like to see it used on a live 100 year old model and watch their skin turn to the same texture a s a 12 year old within 10 minutes.
    I have seen thin fit healthy people die of heart attacks vegan eaters get cancer seen thin people have stokes I have seen over weight people with no issues I wish I had one clear answer on how to live my life I have done fads never touched alcohol until I was about 30 (until I got pressured...)I have never smoked however and I have done days of not eating fasting etc then ive had years of eating junk food then years of protein only meat etc
    I was at the happiest and felt better eating chocolate and drinking ;)
    starving myself and avoiding 99% of food I suffered mental issues and panic attacks because I couldn't find anything that was good for me there was always something that was bad.
    even the best super food will have something that is bad for me.
    what is a gut friendly diet?
    eating nothing?

    Great talk Ruari. As a mom who spent three decades trying to help her daughter overcome chronic worry, fear, avoidance, chronic fatigue, panic attacks..all limiting her day to day existence in the world, the real answer lied in stepping away from the western mental health professionals view and paying attention to the foods that drove the waves of anxiety. The right-for-her toolbox included identifying that foods high in histamine immediately triggered her symptoms. Histamine intolerance is overlooked by the mental health professionals of which our family has given tens of thousands of dollars to only to receive failed after failed protocol. Finally, by taking a closer look ourselves, we identified the relationship between fermented foods, probiotics, whey, most leftovers, canned foods...essentially, foods high in histamine and immediately, she reclaimed her life. Her her body and mind now can begin to heal. Living life on your terms lies in the right-for-you protocol. Our learning is that yes, the answer lies in the gut, but not all guts and brains are alike. To lessen the symptoms and give our bodies a chance to heal, one is required to be self-aware in identifying the food groups that trigger the symptom, thereby uncovering the clues that lead to the right-for-you protocol.

    Good talk!. part of the reason western medicine took the path of waging the battle against microbes may have been a side-effect of the approach western medicine takes. Gut micro biome take some time to restore and evolve i suppose and in modern medicine , we expect problems to be solved within a reasonable time. This leads me to believe, maintaining a healthy gut is more of a preventative measure.

    Thank You, for supporting a long forgotten system that makes alot of difference to the quality of our lives, not many people speak of our digestive system, but when you really
    think about the body and irs working its the gut that is the most influential, cause the brain is fed by the gut.
    I have in all my years never been taught how important healthy gut bacteria is, only now am I fully realising the influence it has on mental health, as well
    disease prevention, which is truly common sense, which sadly has not been common.
    Its about time we stop straving our healthy bacteria and start feeding them conscientiously, and consciously by including Fermented Foods in Our Diet.
    Its Amazing to think, that we can eat a whole meal without feeding abyrhing to our good bacteria, ultimately to our own detriment.
    So thanks again for your very good advice, it is very much appreciated,Please Keep Up the Good Work Of Educating the Public. Kind regards & God Bless
    You & Yours SherrilL.Carss

    This theory had been told several thousand years ago by great saints as part of Ayurveda, Spiritual Astrology and Principles to be followed by humans as per "manyusuktha" Indian mythological books. Also in the book of Mahabharata, Acharya Bhishma says about food as part of the do's and don'ts by humans. May be it is new for western countries but this is about food was explained in detail by Saints so called scientists of those times. Around 5000 years ago..
    Also, they have explained the relation with food and five elements of body that is prepared with. To understand this read spiritual Astrology book.
    For example, to calm down or nullify the saturn effect, Indians consume more gingelly food products.
    To understand this we have to understand the features of Saturn.
    Which is the cause for lazyness. Lot more..
    Anyway congrats for your efforts

    Dear Dr. Ruairi."New revelation in our understanding of human physiology". Who is "us" in "our"? I hope this is not modern scientists/doctors AGAIN ignoring the body of knowledge of ancient medicine. Please show humility and care to speak when tempted to claim achievements - "new revelation" - and stop spreading the anglo-centered view of the world. Please do preface such statements with the scope of your claims. e.g. "new revelation for us at the Such and Such Institute". This detail is no small matter, in the Digital Information Age, at a time when brainwashing can be institutionalized in academic settings and beyond. Thank you for your consideration.
