Decoding Aging: The Science Of Cellular Rejuvenation With Dr. Vittorio Sebastiano

Decoding Aging: The Science Of Cellular Rejuvenation With Dr. Vittorio Sebastiano

It was a career-defining (and perhaps life changing) moment when Dr. Vittorio Sebastiano, a reproductive biologist by training, realized that because we are able to create life, that same body of information could be harnessed to create youth – that is, radically reverse our biological aging process to a younger time point without losing cellular identity. In 2014, he and his lab began unpacking this epiphany. They made the radical decision to conduct their investigations in human cells and tissue rather than in rodents, with the expectation that such a start would be a better bridge to human clinical trials. Flash forward a decade and Dr. Sebastiano and his team stand poised to begin trials in humans. Dr. Sebastiano is, in my opinion, one of the most extraordinary scientists in the longevity space today who flies under the radar of most of us in functional medicine.

Burnout in Healthcare: Causes, Consequences, and Solutions with Dr. Jonathan Prousky

Burnout in Healthcare: Causes, Consequences, and Solutions with Dr. Jonathan Prousky

In the midst of the ongoing pandemic, healthcare practitioners have been working tirelessly to care for their patients. But what about their own health and well-being? Today, I am delighted to welcome back Dr. Jonathan Prousky, Chief Naturopathic Medical Officer at the Canadian College of Naturopathic Medicine, to the New Frontiers Podcast. As a repeat guest and leading expert in personalized mental health strategies, Dr. Prousky offers valuable insights into the challenges facing healthcare practitioners today, especially in terms of the hidden epidemic of physician burnout. In this episode, we explore practical solutions to help healthcare practitioners maintain their own health and well-being while providing care to others. We also touch on the three hallmark signs of burnout and discuss the latest advances in targeted supplementation to manage underlying chronic stress in the workplace. Dr. Prousky’s expertise and practical tips make this an episode you won’t want to miss. As always, please feel free to share, comment, and rate – and let us know your thoughts on this important topic. ~DrKF

Urolithin A: Postbiotic Rockstar on the Longevity Stage

Beyond Mitochondrial Health: Can Urolithin A Slow Down Aging?

In the realm of bioenergetics, few nutrients have burst onto the stage with the impressive force wielded by the postbiotic rock star—Urolithin A. In today’s episode I’m honored to be joined by the brilliant Dr. Chris Rinsch, co-founder of Amazentis / Timeline, as we delve into the profound impact of this remarkable substance and unravel the scientific intricacies behind the microbiome’s transformation of polyphenols from our diet into Urolithin A. You’ll quickly understand why it’s emerging as a potent force in cellular health and longevity.

Beyond Calcium, Vitamin D, and Bisphosphonates: A functional approach to halting bone loss

Resolving Osteoporosis and Optimizing Bone Health – A Tour de Force Update

Did you know that “bone-eating” osteoclast cells are derived from immune cell precursors and are stimulated by inflammation, just like other immune cells? Or that bone has its own glycocalyx whose health is essential to realize the benefits of exercise for bone? Folks, Dr. Keith McCormick is back on New Frontiers with ever-more juicy pearls like these, and with important updates on bone care for functional medicine practitioners and patients alike. Dr. McCormick is living proof that osteoporosis and a history of multiple bone fractures – he had 12 between the ages of 45-50 – are not an irrecoverable life (or death) sentence. In fact, even as he nears 70, Dr. McCormick is out there competing in Ironman and pentathlon events, living his life to the fullest. Dr. McCormick is arguably the top thinker and practitioner on bone health from a systems and functional point of view. His nuanced navigation of diagnostic tools as well as both pharmaceutical and nonpharmaceutical interventions is fully comprehensive and deep. You’ll want to tune in to find out how he navigates his patient cases, casting a wide net for underlying contributing factors, his go-to interventions for specific situations, how he doses supplements, and more. Please do let us know what you think, and leave us a review wherever you listen to New Frontiers – DrKF

Breast Health and Beyond: A Practitioner’s Guide to Functional Testing

Breast Health and Beyond: A Practitioner’s Guide to Functional Testing

Over 270,000 new cases of breast cancer are diagnosed each year in the US. And while BRCA mutations often get the most press, there are other, potentially more critical factors we can address. Today, Dr. Ruth Hobson joins us to delve into the realm of breast health, shedding light on both modifiable and non-modifiable risk factors, and sharing real-life strategies for supporting our patients. We dive into a range of essential topics, from dietary and lifestyle influences to the ongoing debate around Hormone Replacement Therapy (HRT), and venture into the world of functional tests to evaluate hormones and metabolites crucial for comprehensive breast health. We’ll uncover the intricate connection between gut health and breast health – Did you know that breast tissue has its own microbiome?!? – and examine how inflammation, peripheral fat, and methylation impact cancer risk. Bring a pen and paper, this is a deep dive into the hormones and breast health that you won’t want to miss. ~DrKF

Imprintome Mapping: Key to Evaluating Impact of Imprinted Genes on Aging and Disease with Dr. Randy Jirtle

Have You Met Your Imprintome Yet? Here’s Why You Should

I’m thrilled and honored to have Dr. Randy Jirtle join us again today on New Frontiers. Dr. Jirtle’s groundbreaking Agouti Mouse Study has shaped what we know about the influence of early life exposure on methylation and epigenetics. His (current work?/more recent work?), which involves mapping out the imprintome could be the key to understanding how our imprinted genes will influence aging and every known disease and disorder, providing hope that a clear pathway on how to optimize our health for better outcomes is in our future.

Harnessing Nutrient Responsive Genes Against Breast Cancer

I am particularly interested in nutrient responsive genes, especially for altering the risk for and course of conditions such as breast cancer. Nutrient responsive genes, as their name implies, are those whose expression responds to their environment – specifically the nutrients we ingest. This effect is mediated via epigenetic alterations induced by those nutrients. This…
