Supplements and Morning Coffee: Timing Iron, Zinc, Calcium, B Vitamins, and Vitamin D: Nutritionist Leyla Muedin explains that coffee (and tea) can interfere with nutrient absorption and digestion, so certain supplements shouldn’t be taken with morning coffee. Coffee’s tannins and polyphenols can significantly reduce non-heme iron absorption (decaf doesn’t prevent this), and similar binding issues may affect zinc; she recommends taking iron with water at least 1–2 hours away from coffee and pairing it with vitamin C. Because caffeine may increase urination, B vitamins (especially thiamine) may be lost more readily, so she suggests taking them with food but...

Natalie Ochoa, president of Jigsaw Health, details widespread magnesium insufficiency and why it occurs (soil depletion, low plant intake/processed foods, stress-related loss, aging, and medication effects including diuretics and proton pump inhibitors). They discuss the poor reliability of standard serum magnesium testing, the limitations of RBC magnesium testing, and using symptoms such as cramps, twitches, constipation, fatigue, and sleep trouble as clues. Ochoa explains Jigsaw’s sustained-release magnesium malate (MagSRT) designed to reduce GI side effects and how to read labels for elemental magnesium, with typical intake around 500 mg/day. She reviews the 2018 placebo-controlled Scottsdale Magnesium Study (91 participants) sh...

Cardiologist and electrophysiologist Dr. Gregory Marcus, chair of the American Heart Association scientific statement writing group, reveals evidence on coffee/caffeine and cardiovascular health. He discusses how earlier assumptions that caffeine triggers arrhythmias are complicated by genetics, individual risk factors, and mostly observational research. Marcus reviews randomized and observational findings: the CRAVE trial showed no increase in premature atrial contractions but more premature ventricular contractions on coffee days; a trial in post-cardioversion patients found less atrial fibrillation with daily coffee. Observational data suggest lower risks of type 2 diabetes, heart attack, stroke, and AFib among coffee drinkers, while heart failure...

Chemical engineer and MoldCo founder Ariana Thacker discusses mold-related illness, including chronic inflammatory response syndrome (CIRS), as a major blind spot in conventional care for chronic, multi-system symptoms. Thacker recounts developing rapid-onset brain fog, slurred speech, GI issues, hair loss, weight gain, and shortness of breath after six and a half months in a moldy Miami apartment, seeing over a dozen specialists who attributed symptoms to stress or anxiety. They discuss exposures beyond allergy (mycotoxins, VOCs, microbial fragments), genetic susceptibility (HLA haplotypes), and prevalence estimates tied to water-damaged homes. The episode covers home detection (sensory/visual checks, humidity, dust...

Lowering A1C in Prediabetes and Using Less Insulin on a Low-Carb Diet: Leyla Muedin, a registered dietitian nutritionist, answers listener questions about blood sugar and insulin. Responding to Rita, whose hemoglobin A1C rose from 5.6 to 5.8, Layla says “glucose hacks” to blunt carb absorption aren’t appropriate at that level and recommends a strict very low-carb/keto approach (under 25 grams of total carbs per day), avoiding sugar, starchy vegetables, fruit (except avocado), sweetened beverages, and even alternative sweeteners and low-carb processed products; she suggests retesting A1C after three months and avoiding testing during illness or inflammation. She also a...

Leyla Muedin, a registered dietitian nutritionist in New York City, discusses the growing shift from symptom-only “sick care” to a clinically grounded holistic approach to health and recovery. She argues that self-guided wellness routines can leave gaps when underlying medical issues, mental health conditions, substance use disorders, or trauma remain unaddressed, and emphasizes integrating evidence-based clinical evaluation (including labs and deficiency testing) with lifestyle practices. She explains how treating symptoms in isolation misses connections (e.g., stress, sleep, grief) and defines true holistic care as addressing physical, mental, emotional, relational, environmental, and purpose-related factors without rejecting medical treatment. Key comp...

What Triggers Age-Related Belly Fat? New Stem Cell Findings and a Nutrition Perspective: Nutritionist Leyla Muedin discusses research from City of Hope (published in Science) on why belly fat increases with age even without major weight gain, emphasizing the health risks of visceral fat as an endocrine organ linked to inflammation, diabetes, heart disease, and accelerated aging. The study suggests aging activates adipocyte progenitor cells (APCs) and produces an age-specific stem cell population called committed preadipocytes (CP-As) that generate new fat cells, with experiments showing older APCs create more fat cells even when transplanted into young mice. Single-cell RNA...
