Mapping the Placental Methylome: The Key to Early Autism Intervention with Dr. Janine LaSalle

Towards Predicting Autism in Utero with Dr. Janine LaSalle

Hold onto your hats, folks. We’re taking a deep dive into game-changing research with Dr. Janine LaSalle, epigeneticist extraordinaire. With autism rates increasing at an alarming rate, it’s been a huge struggle to really put our fingers on anything for diagnostics or prediction. Dr. LaSalle is on a mission to change that. She’ll walk us through her ground-breaking research around mapping the placental methylome, why it can be used as a surrogate marker for the brain, and how using methylation signatures provides insights into interventions that could potentially correct these issues in utero. Simply amazing!

Cutting Edge Interventions For Patients with Adverse Food Reactions with Dr. Tom Fabian

Challenging Food Reactions? Addressing the Gut Microbiome and More with Dr. Thomas Fabian

In this episode, we’re diving into the forefront of understanding adverse food reactions, a topic that’s experiencing a significant paradigm shift in both perception and treatment strategies. Our guest, Dr. Thomas Fabian, a leading expert on the role of the microbiome, will shed light on the underlying pathophysiology of these reactions. We’ll discuss specific gut microbes and microbial functions identified in recent studies, providing concrete examples of their involvement in various types of adverse food reactions.Join us as we navigate through the latest advancements in immune tolerance understanding, microbial variances in the gastrointestinal tract, and the profound influence of GI physiology on adverse food reactions.Stay tuned for an enlightening discussion that will undoubtedly shape the future of functional medicine practice. ~DrKF

Microbiome Reset: Building Childhood Resilience with Dr. Elisa Song

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

I’m delighted to welcome back Dr. Elisa Song, a respected colleague and pioneer in pediatric functional medicine. Today, we’re delving into the critical intersection of the gut microbiome and pediatric health. In today’s landscape, families are confronted with daunting challenges. Between the 3000 chemicals hiding in ultra-processed foods, alarmingly high sugar content (sometimes as much as 14 teaspoons in a single drink!), and the pervasive presence of antibiotics in our food supply, it’s no surprise that we’re seeing negative changes in the microbiome, worsening metabolic health, increased allergies, autoimmune disease, and neurodevelopmental issues.

PCOS and Iron Overload – Underappreciated and Important Biochemical Connections

Insulin resistance, excess weight, fatty liver, infertility, and elevated androgen levels – these are clinical features common to two conditions that we wouldn’t necessarily think to connect: polycystic ovary syndrome (PCOS) and hemochromatosis. Interestingly, excess iron is a common finding in BOTH conditions. A new patient of mine – we’ll call her Anne – recently presented with PCOS along with mildly elevated iron levels. In this blog, I tease out the relevance of this, especially in the context of emerging research on the connections, and explain how I put those considerations into the development of her treatment plan.

Urolithin A and GLP-1 Agonists: A winning combination with Dr. Anurag Singh

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

GLP-1 agonist drugs such as Wegovy and Ozempic have burst onto the scene, offering exciting prospects for metabolic health. And while I find the potential of these drugs truly fascinating, amidst their promising benefits, there’s a significant concern looming that can’t be overlooked —the risk of substantial muscle loss. It’s a topic that hits close to home for me, especially considering the pivotal role of muscle in overall health and longevity.

Past, Present, and Future of “Biological Aging” with Dr. Fitzgerald

Team DrKF sat down with Dr. Fitzgerald to pose some questions about the “state of the state” of longevity research, current controversies and future directions, and where she sees her work fitting into it. When it comes to defining and using measures of biological age, where does the science currently stand? To understand where we currently stand, and why changes are afoot, we have to first consider where we’ve come from. When Steve Horvath at UCLA released the first epigenetic biological age clock in 2013 it marked the entry of longevity medicine into the mainstream (referred to as biogerontology in science, anti-aging medicine in some clinical circles).
