    Gut Microbes as Frenemies with Dr Joe Alcock

    Gut Microbes as Frenemies with Dr Joe Alcock

    *The information in this podcast is intended for Healthcare Practitioners.


    Dr Joe Alcock is not your typical MD. Joe’s day (or night) job is as a practicing emergency Physician and a Professor in the University of New Mexico Department of Emergency Medicine. However, Joe also has a deep interest in both evolutionary medicine and microbiome science and has the unique skill of integrating and translating these disciplines into practical outcomes.


    In this episode, Dr Alcock explains how, since time immemorial, our gut microbes have had a love/hate relationship with us, and how this concept of ‘conflict and co-operation’ can explain the trials and tribulations of research on microbiome composition in disease states, probiotic successes and failures and a new approach to feeding ourselves and our resident microbiome. Tune in for a fun and insightful tour of the microbiome as Joe discusses conditions such as gut health, insulin resistance and mood disorders.

    Resilience in the Face of Trauma with Professor George Bonanno

    Resilience in the Face of Trauma with Professor George Bonanno

    *The information in this podcast is intended for Healthcare Practitioners.


    In this episode, Nathan speaks with George A. Bonanno, a Professor of Clinical Psychology at Columbia University, Teachers College. His research focuses on how people respond to potentially traumatic events, such as disaster, war, assault and life-threatening injury, whether they present with post-traumatic stress disorder or not. These studies have revealed that the natural response to stressful situations is not trauma, but resilience, and as such, we may be underestimating our ability to rebound without suffering long-term consequences.


    George has authored two books, The Other Side of Sadness: What the New Science of Bereavement Tells Us About Life After Loss and The End of Trauma: How the New Science of Resilience is Changing How We Think About PTSD.


    Highlights



    How history has shaped our understanding of trauma (5:00)
    Recovery patterns following a traumatic episode (11:00)
    The resilience blind spot (15:30)
    Potentially traumatic events (PTEs) (17:00)

    The resilience paradox (31:00)
    How to build your resilience (37:00)
    Future research in the field of resilience (48:00)

    Life through the lens of evolutionary psychology with Professor Glenn Geher

    Life through the lens of evolutionary psychology with Professor Glenn Geher

    *The information in this podcast is intended for Healthcare Practitioners.


    In this episode, Nathan speaks with Glenn Geher, Professor of Psychology and Founding Director of Evolutionary Studies at the State University of New York at New Paltz. Professor Geher has been the recipient of the New Paltz Alumni Association’s Distinguished Teacher of the Year Award, along with Chancellor’s Awards for both Teaching and Research Excellence from the State University of New York. He has penned several books including Evolutionary Psychology 101 and more recently, Positive Evolutionary Psychology, and contributes a regular blog to Psychology Today, called Darwin’s Subterranean World.


    This episode serves as a brilliant introduction to evolutionary psychology, as Professor Geher explains how an evolutionary perspective can shed light on modern-day issues, such as mental health conditions. He describes the significance of living in an environment we, as humans, were not evolved to exist in – coined an evolutionary mismatch. This fascinating discussion provides insight on how the principles of evolutionary psychology helps us understand human behaviour and the human experience.


    Highlights



    An evolutionary perspective on mood disorders (7:00)
    Our minds are not evolved for large scale politics (19:00)
    Criticisms of evolutionary psychology (24:00)
    Neuroticism may have served a purpose (32:00)

Good way to keep abreast

Good show for practitioners and anyone interested in deeper news and research on nutrients, supplements, diet, wellness.
One suggestion: it could be made more palatable for a wider audience if the show was shorter in duration. 30 mins is a good amount of time for a listener to get enough in depth but not so long it feels prohibitive to listen often… which is my case.

Informative and interesting

I always learn something new when I listen to this, translates the latest science into understandable bite sized chunks. Nathan is a great host and asks all the right questions!

Circadian rhythms

A fascinating podcast on the effect of light and sleep on health. Great listening!
