Harnessing the Microbiota-Gut-Brain Axis to Improve the Stress Response

New understandings of the intricate connections between gut and brain are revolutionizing medicine’s approach to mood, brain function and digestion, giving our “gut-wrenching experiences” or our “gut-feelings” a lot more meaning than they already have. The emerging evidence in this area is providing new tools to influence both gut and brain health.

What does “Evidence-based” look like in Functional Lab Testing?

As the name suggests, New Frontiers is about staying ahead of the curve in functional medicine, continually asking critical questions, and being open to self-critique. This couldn’t be more true than when it comes to advanced functional testing. Today I’m pleased to talk with a familiar face and renowned hormone testing expert, my friend Mark Newman. Mark created the DUTCH test based on his decade-long experience in novel test development, and joins New Frontiers to talk about all things hormones: from cortisol & thyroid health to estrogen, progesterone and androgens, the importance of analytical and clinical validation of tests, and his upcoming research on various hormone replacement therapy methods.

Exploring Longevity Medicine and Epigenetic Aging with Dr. Lucia Aronica

What can queen bees teach us about epigenetics? And what do polyphenols, stress, and sunlight have in common? Hint: it has to do with longevity science. To mark our exciting paper on the Potential Reversal of Epigenetic Age Using a Diet and Lifestyle Intervention we are hosting a series of podcasts focused on the science of epigenetics and longevity, and kick things off with talented researcher and Stanford lecturer, Dr. Lucia Aronica. Dr. Aronica is a passionate advocate of lifestyle medicine and is currently leading the epigenetic analysis for the largest randomized clinical trial in the field of personalized nutrition on low carb vs. low fat diets.

By Nutrition Resident Megan Piffner (@MeganPfiffnerNutrition) Chickpeas for dessert?! There is nothing better than having a treat that also gives you fiber, protein and micronutrients. Chickpeas are rich in potassium. They also have iron, B6, magnesium, and calcium. ½ a cup of chickpeas gives you 19.5 grams of protein, 60.5 grams of healthy carbs and…

The Top Seven Benefits of Turmeric and Two Major Problems

Most people don’t realize that inflammation is at the root of nearly every chronic disease, and the symptoms that go along with them. Things like joint and muscle pain, brain fog, fatigue, depression, anxiety, weight gain, and more are all rooted in inflammation. And while we do have medicine like NSAIDs to reduce inflammation, these come with side effects. Which is why natural solutions like turmeric are invaluable.

The Impact of Therapeutic Dietary Interventions on Disordered Eating

For clinicians, therapeutic dietary interventions such as an elimination diet, a cardiometabolic diet, intermittent fasting, or caloric reduction, are some of the most important tools we have in functional medicine. Transitioning to healthful eating can for some patients be a joyous experience of liberation, but then for others it can be restrictive and problematic, and sometimes fall in the continuum of eating disorders. How do we tease this out? How do we screen for vulnerability in disordered eating and support patients who fall within this spectrum? In this episode of New Frontiers, Dr. Carolyn Fisher PhD, a licensed clinical psychologist who specializes in helping individuals with binge eating, emotional eating, chronic dieting, and other medical conditions heal their relationships with food.

Short-Chain Fatty Acids: Strengthen the Gut-Brain Health Connection with Butyrate

All SCFAs have wide-ranging therapeutic benefits, but in this article we’ll focus on butyrate as a therapeutic agent for gut and brain health. Butyrate is the food for the colonocytes, the thin layer of cells that comprises the lining of the large intestine. Within the intestinal environment, it protects and supports the mucosa, gut motility, and the commensal bacteria of the colon. Although butyrate is largely present in the gut, it can also have effects on the brain via the gut-brain axis, as well as by lowering inflammation, stabilizing DNA structure, and sequestering harmful metabolic by-products like ammonia.

The Role of Neuroplasticity in Chronic Illness & Healing

Within the realm of functional medicine, we are quite successful at restoring some order to this cacophonous symphony of chronic illness, and getting our patients better to an extent. However, there is a final piece – a missing piece, if you will – and my guest today, Ashok Gupta, shares how neuroplasticity affected his own healing journey of chronic fatigue syndrome and why this final piece is integral to restoring optimal health. Ashok is a speaker, filmmaker, and health practitioner who created a program for retraining the brain using interventions to facilitate neuroplasticity. In this episode of New Frontiers, we discuss neuroplasticity dysfunction, how to rewire the brain’s survival response, and so much more. Folks, this conversation goes well beyond the patient-physician encounter and explores the depths of our homes, our communities, and how we experience the world around us.

Comparing Saliva, Urine, and Serum Hormone Testing: Choosing the Best Test for Each Patient

Have you ever looked at serum hormone levels and scratched your head, wondering why there was such a difference between your patient’s clinical signs and the numbers on the report? Felt unsure whether to look at bioavailable hormone markers or their metabolites? Not surprisingly, when it comes to endocrinological health, there are just as many questions as hormones (and there are over 50!). My guest in this podcast, Dr. Lylen Ferris, gives us very clear and user-friendly guidance on appropriate hormone testing, interpreting results from different specimens and, most excitingly, using novel biomarkers, such as allopregnanolone. Having completed her naturopathic residency with Dr. Kimberly Windstar, and after years of teaching and mentoring medical students on gynecology and women’s health, Dr. Ferris has plenty of brilliant clinical pearls to share with us! Please share, comment, and leave us a starred review if you wouldn’t mind! Thank you!
