Folks, I'm thrilled to be back once again with my friend and colleague, Dr. Tom Fabian - leading functional nutrition practitioner trained in the molecular biology of aging. Together with his training and experience as the clinical laboratory consultant for Diagnostic Solutions Lab, Dr. Fabian shares a wealth of practical applications for microbiome research in functional medicine and clinical settings. In this episode, we explore key microbial species for longevity and how to boost their levels, inflammaging of the microbiota, often-missed leaky gut clues on GI-MAP reports, the small intestine as a key site for immune tolerance, how microbiota influence epigenetics, and much more. It’s truly exciting to learn from his extensive research expertise in the role of the human microbiome in health, disease, and aging, so make sure you get ready to take notes and bookmark this page – you’ll want to come back for more! Thanks for listening, and leave us a review wherever you listen to New Frontiers! ~DrKF

Dr. Elisa Song is one of those clinicians that I could just keep talking to! She's a respected colleague and pioneer in pediatric functional medicine with so many practical tips for navigating childhood illness and health. Need to get your kiddo/patient through a blood draw they don't want to do? Or get your picky eater to take their supplement? Dr. Song has the answers. I appreciate her candor as she talks about how and why her practice has evolved in certain areas (such as in the use of targeted probiotics and even "psychobiotics" for autism, ADHD, anxiety, OCD and more) and in spelling out which supplement brands and doses she uses and why. Dr. Song tackles the immense challenges impacting the health of our kids and teens head on with positivity and smart, doable strategies for lasting success. This is a fascinating and empowering discussion with many clinical pearls that I will be implementing both in practice and for my own daughter going forwards. I hope you enjoy it too! ~DrKF

Smart, Actionable Strategies for Childhood Resilience, with Dr. Elisa Song

Even as we prioritize natural interventions in functional medicine, GLP-1 agonist drugs such as Wegovy and Ozempic offer sometimes life-changing support for those who have long struggled with resistant overweight/obesity and high blood sugar. However, there are side effects, including the risk of substantial muscle loss and sagging, aged skin ("Ozempic face" as it's indelicately known). It's a concern that hits home for me, considering the pivotal role we know that muscle plays in overall health and longevity.

In this New Frontiers podcast episode I welcome back Dr. Anurag Singh to unravel the complexities of these issues. We explore the interplay between metabolic health and muscle preservation, touching on everything from the mechanisms of GLP-1 agonists and their long-term effects on aging and sarcopenia, to the promising potential of dietary and lifestyle interventions to counteract negative effects. We consider the potential for one of my all-time fave postbiotic epinutrients - Urolithin A - to assist by supporting mitochondrial health and preserving/enhancing muscle quality. This timely conversation is one you won't want to miss. Tune in and please leave us a review wherever you listen to New Frontiers. – DrKF

Mitigating Muscle Loss from GLP-1 Agonists, with Dr. Anurag Singh

Dr. Sandison confesses that when she first heard Dr. Dale Bredesen talk about his work reversing cognitive decline and Alzheimer's disease she was skeptical. But when she started to apply the Bredesen principles in her clinical work and saw just how meaningful the improvements were to patients' symptoms and quality of life, as she puts it: "...how do I do anything else with my life, but basically tell as many people who will listen that this is possible?" She then went on to found the first two residential care facilities for individuals with cognitive decline that are based on the Bredesen approach. She's published research on her clinical outcomes and is continuing to gather more data for publication. The information and inspiration she shares are relevant to anyone dealing with cognitive decline, caring for someone with cognitive decline, or even those of us who want to preserve and optimize cognitive function as we move through life. I found her report that environmental toxins were one of the most common findings among her patient population illuminating. - DrKF

Tackling Alzheimer's Disease Head On - the Inspiring Work of Dr. Heather Sandison

Get ready for a deep dive into the world of cellular senescence and its implications for aging. Dr. Greg Kelly joins me on New Frontiers to explain the science behind targeting this Hallmark of Aging and share natural compounds and activities that target cellular senescence. I am particularly excited for you to hear his thoughts around dosing and cyclical timing of exposure to senolytic compounds, such as fisetin, luteolin, quercetin, and piperlongumine, and why that may make the difference between having the effect you want... or not. Don't miss his advice on smart exercise tweaks for aging and the caution that overdoing it with exercise in our later years is much more harmful than it was in our twenties. Lots to unpack here. Enjoy! - DrKF

Targeting Senescent Cells? Dose and Timing Matters - with Dr. Greg Kelly

I'm excited to welcome Dr. Barry Sears, the renowned creator of the Zone Diet and a pillar in our field. Dr. Sears has not only authored bestsellers but has also made incredibly important contributions to clinical practice which we still rely on today: He is, for instance, the scientist who put the use of the AA:EPA ratio on the map. Dr. Sears provides elegant and accessible explanations of the unassailable importance of diet in addressing inflammation, metabolic health, chronic disease, and longevity, and the role that fatty acids play in that milieu. And while he and I might not agree that polyphenols need to be absorbed intact for benefit - there's plenty of evidence that their postbiotic products are very important players, especially in their interactions with the epigenome - his concerns about the chemical structure of highly concentrated fish oil supplements (with the potential for isomerization, as he argues) has opened my eyes and is important, without doubt. I think the jury is still out as to whether there is a negative influence of isomerization in highly concentrated EPA and DHA, but it's worthy of further investigation and (importantly) is another factor in the argument for a whole-food approach. - DrKF
