Food for thought: How your belly Don’t get hangry: feed your 1 day ago   14:31

TEDx Talks
"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

Latest study doesn't find a correlation between c-section and lack of bacteria from the mother, apart from children's guts populated with more hospital bacteria, but rather blames the antibiotics used during the c-section, that are however used in regular labour too.

He said "mum", not "mom", dear subtitle writer
amazing insight: " you are more bacteria than you are human". brilliant
MMS drops. There's a reason they took down the entire "MMS Testimonials" YouTube channel. Because Humans are not a fermentation based hindgut fermenting species, we are obligate carnivores, which require the least possible amount of pathogens and symbiants in our digestive system and, absolutely none in our blood or organs. See Bob Beck's copious lectures for the results of removing 100% of the pathogens from our blood, and Jim Humble's books and lectures for the results of removing them from our intestines and organs. See the books: "The Parasite Menace," "Fiber Menace" and "The Plant Paradox.

In 2019 our understanding of pathogens in the digestive system is based on barbaric science. Yes, we have opened a new avenue of important research. But naivety and a lack of spiritual development is occluding our perception of the underlying reality: Pathogens are pathogenic, not symbiotic. This is heresy, I know.

Don’t get hangry: feed your Food for thought: How your belly 1 day ago   18:57

One of the two best predictors of success in life is self-control (the other is intelligence). Professor Brad Bushman has been studying human aggression for over 25 years. Aggression often starts when self-control stops. Bushman discusses his research on the link between low self-control and aggression. He focuses on the link between levels of glucose (blood sugar) and self-control. Glucose provides our brain with the fuel it needs to exercise self-control, including control of angry feelings and aggressive impulses. Bushman’s research shows that when people become hungry, they also tend to become angry and aggressive, captured by the term “hangry” (hungry+angry). Healthy foods like veggies, fruits, and whole grains can make people less hangry. Self-control can also be strengthened, like a muscle, through exercise.

Brad J. Bushman (Ph.D. 1989, University of Missouri) is a professor of communication and psychology at The Ohio State University, and a professor of communication science at the VU University, Amsterdam. He holds the Margaret Hall and Robert Randal Rinehart Chair of Mass Communication. For over 25 years he has studied the causes, consequences, and solutions to the problem of human aggression and violence. He is a member of President Obama’s committee on gun violence, and has testified before the U.S. Congress on the topic of youth violence. He has published over 170 peer-reviewed journal articles. According to Google Scholar, his articles have been cited over 25,000 times. He is ranked #2 among communication scholars cited in Google Scholar. In 2014 he received the Distinguished Lifetime Contribution to Media Psychology and Technology, American Psychological Association. His research has challenged several myths (e.g., violent media have a trivial effect on aggression, venting anger reduces aggression, violent people suffer from low self-esteem, violence and sex sell products, warning labels reduce audience size). (One of his colleagues calls him the “myth buster.”) His research has been published in the top scientific journals (e.g., Science, PNAS), and has been featured extensively in the mass media (e.g., BBC, New York Times, NPR).

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
