About this episode
Welcome back to another eye-opening episode of Ditch the Lab Coat with Dr. Mark Bonta! While we usually dig into the science behind medicine’s biggest questions, this week we’re tackling the latest health fads and “wellness” trends lighting up your social feeds—from infrared saunas and cold plunges to mouth taping and chlorophyll water.Joining Mark is Dr. Samir Gupta, a leading Canadian health communicator, clinician, and respirologist known for translating the complex world of medical research into practical advice you can trust. Together, they sift fact from fiction on everything from the cardiovascular perks of sauna bathing (is it really the “new running”?), to the surprising metabolic effects of cold immersion, and what science truly says about intermittent fasting and its potential risks.If you’ve ever wondered whether that daily cold plunge will actually boost your immune system, or if packing your cart with ultra-processed foods is as dangerous as smoking, this episode is for you. Mark and Samir unpack the real data—both the encouraging findings and the cautionary tales—behind today’s most viral wellness hacks, including why you might want to think twice before taping your mouth shut or spending a fortune on chlorophyll water.They also take a deep dive into the gut microbiome—what it actually is, how it impacts cravings and disease risk, and why you shouldn’t rush to buy the latest “miracle” probiotic kit just yet. Plus, a frank discussion on the harms (and sometimes hilarity) of the social media health machine.Whether you’re a wellness skeptic, a trend-chaser, or just someone confused by conflicting health advice, this episode delivers the scientifically sound, refreshingly honest perspective you’ve been looking for. Plug in for myth-busting, evidence-backed conversation—and a few laughs—about what it really takes to live healthier, longer, and smarter.Episode HighlightsSauna Science Surprises : Frequent sauna use, especially Finnish-style, is linked to reduced heart disease and dementia risk, with short- and long-term benefits.Infrared vs. Traditional Saunas : Infrared saunas might differ from classic dry saunas; less data supports their health claims, especially regarding respiratory or cardiovascular outcomes.Benefits and Limits of Cold Plunge : Cold plunges activate brown fat and may modulate immunity, but benefits depend on regular, protocol-based use—not occasional dips.Intermittent Fasting: Mixed Signals : Intermittent fasting can offer metabolic perks and moderate weight loss, but recent studies raise concerns about potential long-term cardiovascular risks.Ultra Processed Foods: New Tobacco : Growing evidence ties ultra processed foods to shorter lifespans, heart disease, cancers, and mental health risks—diet quality matters deeply.Fad Di
