A Holistic Pediatrician on Eczema, Gut Health & Raising Healthy Kids with Dr. Carole Keim
Eczema is the itch that rashes, not the rash that itches. It starts as dry skin, the scratching inflames it, and then allergies, foods, pets, and pollen stack on top until a flare shows up. Lower the total load anywhere and you help the skin everywhere. Your child's baseline is being built in the gut, and diversity is the whole game. A wide variety of real foods grows a wide variety of gut bacteria, and that is the quiet foundation under calmer skin, steadier moods, and fewer flares. You do not have to win dinner to make progress. Carole feeds her own picky eaters with traced bento boxes, free range snack plates, and fun utensil nights, and her closing line is the one I keep repeating: small changes add up, and you cannot out supplement a real life lifestyle.
Magnificent Mushrooms: Lion’s Mane – Memory, Focus & Brain Health
On this episode of Vitality Radio, Jared takes a deep dive into Lion's Mane, one of the most talked-about medicinal mushrooms for cognitive health, focus, memory, mood, and nervous system support. Jared explores the fascinating history of this unique mushroom, the science behind compounds like hericenones and erinacines, and how they may support nerve growth factor (NGF) and neuroplasticity. He reviews human clinical research on cognitive performance, mood, stress, and long-term brain health while helping listeners understand the differences between powders, extracts, capsules, gummies, fruiting body products, and mycelium-based supplements. Jared also shares his personal experience using Lion's Mane, discusses practical dosing strategies, and explains how to combine it with other supplements and lifestyle habits to support healthy brain function and overall vitality.
Life on Earth 101: The Genetics of Aging, Identity, and Everything In Between
Genetics is not static. Contrary to popular belief that our DNA "never changes," Park explains that copying errors accumulate over a lifetime (genetic drift) — like a photocopy of a photocopy gradually degrading. Epigenetics is the real software layer. Genes themselves matter less than which ones get switched on or off (via methylation and acetylation) — explaining why a heart cell and a brain cell share identical DNA yet function completely differently, and why humans and chimps can share 98% of their genes yet look nothing alike. Aging is a story of cellular depletion, not just mutation. Using the "lint trap" analogy, Park frames aging as a gradual loss of stem cell reserve and immune flexibility — illustrated by the case of a Dutch supercentenarian whose immune system had only two clonal variants left, versus the ~10,000 a healthy person carries.
Treating Anxiety Like a Poison: An ER Doctor’s Approach to OCD
There is no morality in a ritual: Scott explains why he tells a child that washing three times and washing a thousand times are equally safe, and what opens up for that child once neither one is right or wrong. The brain is not broken, it is early: checking, rechecking and ritual are useful adult skills. Pilots and resuscitation teams run on them. Scott's framing is that the timing is off, not the child. Why panic is a normal reaction at the wrong moment: the fight-or-flight response is doing exactly what it was built to do. Learn the question Scott asks himself before anything else, and the answer he says out loud.
Water’s Job Isn’t To Hydrate You
Dormant, not dead: Todd's mentor pushed back on the idea that treated water is beyond saving. The distinction matters, because one of those words means there is something you can do about it. The order of operations most people get backward: if you filter after you revitalize, Todd says you have undone the work. Learn where each step belongs in the sequence. RO, distilled, spring and tap are four different tools: Todd assigns each one a job instead of crowning a winner, and he is specific about when he reaches for reverse osmosis and why he does not drink it every day.
The Vitamin Your Child’s Brain May Not Be Getting
A transport problem, not a diet problem: Lindsey describes autoantibodies that bind the folate receptors at the blood-brain barrier, so folate can be present in the body and still not get where it is needed. Why this went unlooked-for so long: the reference-standard test was a spinal tap. A blood test changed who gets evaluated, and Lindsey walks through what it involves and what it currently costs. How she thinks about a child who is always flaring: when the pattern stops looking like flare-and-recover, she looks harder at infection, and explains why tick-borne illness sits so high on her list.
This Might Change Your Life: Kim Ressler’s Health Journey of Finding Answers After 11 Years
Discover why doing everything “right” can still leave you feeling unwell, and how generic health advice often fails when it doesn’t match your unique biology. Understand how your genetics influence energy, sleep, metabolism, and detox, and why that missing 1% difference can completely change your health outcomes. Learn how shifting from guessing to personalized insight can simplify your health journey, helping you stop chasing trends and start working with your body.
Why Everyone Is Toxic: The Invisible Burden Affecting Modern Life
Discover how repeated exposures from food, water, air, packaging, cookware, and personal care products can gradually increase the body’s toxic burden. Understand why genetics, nutrition, digestion, mitochondrial energy, sleep, nervous system balance, and drainage may influence how well your body handles environmental exposures. Learn how to support your natural detoxification processes with whole foods, purified water, restorative sleep, daily movement, regular elimination, and one manageable low-toxin swap at a time.
Fructose and the Ancient Survival Pathway Driving Modern Metabolism
Discover how fructose may act as more than a source of calories by signaling the body to conserve energy, store fuel, and reduce cellular energy production. This survival mechanism may become problematic when repeatedly activated. Understand how added sugar, high-glycemic foods, dehydration, alcohol, poor sleep, and hypoxia may converge on fructose metabolism, helping explain why seemingly different lifestyle interventions can influence many of the same metabolic pathways. Learn why whole fruit differs from concentrated or processed sources of fructose, how cellular energy availability may influence cravings and metabolic health, and why reducing relentless activation of this conservation pathway may matter as much as trying to boost mitochondrial function.
Joy in Medicine: How Physicians Can Find Meaning Beyond Burnout
Discover why many high-performing doctors look successful on the outside while feeling disconnected, overwhelmed, or misaligned on the inside. Understand how personal mission, values, and decision-making frameworks can help physicians choose opportunities that support joy instead of draining it. Learn why slowing down, self-reflection, coaching, and compassionate honesty can help doctors reconnect with their inner voice and next right step.
Why Iodine May Be the Missing Piece in Thyroid Health
Discover why iodine supports more than the thyroid and may also play an important role in the breasts, ovaries, prostate, pancreas, and hormone production. Understand how environmental halides such as bromide and fluoride may compete with iodine and contribute to lower iodine availability in the body. Learn why urinary iodine testing, individualized supplementation, hydration, mineral balance, and whole-person care may provide a broader picture than relying on one thyroid marker alone.
