  • #47 Do Organics Really Make You Healthier-Or Just Poorer?
    Send us a textOrganic food often sounds like a smarter, healthier choice—but is it really worth the extra cost? In this episode, we dig into the scientific evidence behind organic foods, pesticide risks, and whether you're buying better health or just paying for a better-sounding label.We begin by breaking down the steep price differences between organic and conventional food. According to the USDA, Americans spend roughly $1 trillion annually on food at home, averaging over $3,100 per person. Organic options can increase grocery bills by 50% or more, as LendingTree reports in this price comparison analysis. My own market trip found Fuji apples nearly double in price, and wild-caught salmon more than twice as expensive.But do organics deliver better health outcomes? Most organic foods contain lower pesticide residues, which 85% of Americans cite as a concern. Yet research shows these lower levels don’t clearly translate to better health. Rodent studies show harm at extremely high pesticide doses, far above what’s found in conventional produce. Human risk data mostly comes from farm workers, not everyday consumers.A 2023 meta-analysis of 50 studies found that organic diets reduced blood pesticide levels and increased plant-derived phenolics, but showed inconsistent results for antioxidants. Cancer data is also mixed. One observational study found no clear differences across 15 cancer types. Another study of 68,000 participants linked organic food with perhaps a  0.6% lower risk of cancer incidence (JAMA Internal Medicine). However, organic eaters also are more likely health oriented (perhaps exercise more, sleep better), so lifestyle may explain the difference—not the food alone.I ran the numbers: avoiding one case of cancer might require 150 people to eat organic, costing about $300,000 in additional food expenses to avoid 1 cancer. And since organic prices may lead families to buy less produce overall, there’s a tradeoff. We know from a meta-analysis that increasing fruit and vegetable intake (organic or not) is linked to a 13% reduction in mortality and a 35% drop in cancer risk. That’s a far more impactful move.If you’re looking for a middle ground, consider using the Environmental Working Group’s Dirty Dozen and Clean 15 lists. While not a neutral source, their rankings can help prioritize which foods might be worth buying organic. Washing produce also helps reduce, but not eliminate, pesticide residues.Takeaways:Organic foods have lower pesticide levels but no clear, consistent health advantage.The biggest health gain comes from eating more fruits and vegetables—regardless of whether they’re organic.If organic costs limit your produce intake, stick with conventional and focus on volume, variety, and other wellness investments like better sleep or exercise.As always, I’d love to hear what you think. Does this shift how you shop? Let me know—and share this episode with someone navigating the same choice.

  • #46 Why the US Spends So Much on Health Care
    Send us a textWhy are U.S. health care costs so high—and what does that mean for you and your family? In this episode, I dive into the real reasons behind America’s staggering health care bills.We start with a story that hits close to home—a $189,000 outpatient cancer surgery bill followed by $12,000-a-month immunotherapy—and I unpack how even with Medicare coverage, the pricing dynamics can feel shocking. Using my experience as a physician and health policy researcher, I explain why these massive charges happen and where the system is breaking down.At the national level, we now spend over $5 trillion a year on health care—roughly 18% of our GDP—and this number is growing far faster than inflation. This growth threatens the solvency of key programs like Medicare, which is projected to run out of funds by 2033 (Health Affairs). Employers are also feeling the pinch, with average family coverage costs now topping $25,500 annually (WSJ). Individuals, especially those using ACA exchanges, face rising premiums—some increasing by 20–30% next year (Axios)—and deductibles between $3,000 and $5,000 are now typical.Despite all this spending, our health outcomes are among the worst in the developed world. The U.S. ranks 33rd in infant mortality and 32nd in life expectancy out of 38 OECD countries, even though we spend about $12,000 per person annually—nearly three times the OECD average (America's Health Rankings).So, what drives these costs? It boils down to three factors: high prices, high utilization, and high administrative overhead. Prices for common procedures are far above international norms—a CT scan in the U.S. costs around $900 compared to $279 in the Netherlands and just $97 in Canada (Health Imaging). U.S. physicians, nurses, and hospital executives also earn significantly more, contributing to overall spending (Medscape; JAMA).On the utilization front, studies estimate that around 25% of all care may be unnecessary, driven by defensive medicine, patient expectations, and incentive structures that reward more procedures—not necessarily better outcomes (PGPF; Choosing Wisely).Even administrative overhead plays a massive role: nearly 25% of U.S. health care spending goes to bureaucracy—four times what’s typical in simpler, single-payer systems (Health System Tracker; Health Affairs%20of%20US%20GDP)).If you’re wondering why your doctor spends just 17 minutes with you or why your premiums feel like a second mortgage, this episode offers the context—and data—to help you understand what’s really going on.Takeaways: Start asking about cash prices—especially if you're still in your deductible phase. Preventive steps like regular exercise may offer the highest return on investment when compared to costly downstream care. And above all, consider your plan carefully during open enrollment.For deeper insights, links to all the studies mentioned, and access to my newslet

  • #46 Can we reduce our risk of stroke?
    Send us a textWe often hear about heart disease prevention, but stroke—a condition nearly as common and often more disabling—gets far less attention. In this episode, Dr. Bobby is joined by cardiologist Dr. Anthony Pearson to uncover what science really says about stroke prevention, the distinct types of strokes, and what practical steps you can take today to lower your risk.Together, they explore the two major types of stroke—ischemic and hemorrhagic—and explain why strokes caused by clots or vessel rupture can have very different causes and consequences. The data shows nearly 800,000 Americans experience strokes annually, and about half of survivors live with long-term disability (CDC; NIH). Yet most of us are unaware of the modifiable risk factors that account for up to 90% of stroke risk (INTERSTROKE Study).Dr. Pearson emphasizes the number one culprit: high blood pressure. It triples individual risk and contributes to half of all strokes, with randomized trials like SPRINT showing that aggressive control reduces both stroke and mortality (SPRINT Study). Both doctors also discuss physical activity—while Dr. Bobby cites strong associations between exercise and reduced stroke risk (BMJ Review), Dr. Pearson cautions that current evidence is largely observational and inconclusive.They also explore the role of lipid levels, citing that high ApoB or LDL may increase risk in strokes caused by carotid atherosclerosis, but not necessarily in cardioembolic strokes. Dietary improvements, particularly following a Mediterranean-style diet, have shown benefits, including reduced stroke risk in randomized trials like PREDIMED.Beyond traditional risk factors, they also explore loneliness as a newer area of concern. A recent study linked persistent loneliness in adults over 50 to a 50% increased stroke risk (Lancet eClinicalMedicine), highlighting the complex social and behavioral factors at play.Dr. Pearson discusses atrial fibrillation (AFib) and why it’s a key cause of cardioembolic strokes—especially relevant given that wearables like Apple Watch now help detect AFib early. They also touch on controversial screening approaches, warning against routine carotid ultrasounds and unwarranted treatment of asymptomatic brain aneurysms.Importantly, Dr. Bobby highlights the signs of stroke—sudden weakness, numbness, speech difficulties, or confusion—and urges immediate ER visits to enable timely treatment like thrombolysis, ideally within four hours of symptom onset.As always, they wrap by challenging popular myths. Dr. Pearson explains why aspirin, once widely promoted for primary prevention, is no longer recommended due to increased bleeding risk, especially into the brain. He also debunks the idea that supplements like fish oil or B vitamins help prevent strokes, noting no benefit in recent large trials.Takeaways:Know your blood pressure and cholesterol levels—and treat them if needed. These remain the top modifiable risks for stroke.Prioritize physical activity, even if trial data is imperfect—it benefits vascular health broadly and may reduce stroke risk.Stay socially connected: chronic loneliness has emerging links to stroke risk, highlighting that prevention isn't just physical—it's relational.To continue learning how to live long and well, visit drbobbylivelongandwell.com.

  • #45 Over Our Skis: Hype Beyond Evidence
    Send us a textDr. Bobby examines how legitimate medical treatments often get overextended into unproven health claims—why it happens, why it matters, and how to spot it.Building on last episode’s theme of health hype, this installment digs into examples where therapies with real medical uses (like vitamin C, B12, hyperbaric oxygen, and stem cell therapy) are being promoted far beyond what the evidence supports. Dr. Bobby unpacks the flawed logic of “theory plus anecdote plus expert equals evidence” and explains why even well-intentioned health advice can go too far when it skips the evidence.You’ll hear about the historical rise and modern misuse of vitamin C—from preventing scurvy to overstated claims of immune boosting. The episode dives into vitamin B12, which has real benefits for those with deficiencies but is often marketed as a cure-all without support. Hyperbaric oxygen therapy, which is FDA-approved for very specific conditions like carbon monoxide poisoning and diabetic ulcers, is another example—now advertised for fatigue, brain fog, and aging without strong data to back it. And stem cell therapy, which truly helps in leukemia and bone marrow failure, is being extended to treat everything from dementia to heart disease—despite the lack of proven efficacy in these areas.Dr. Bobby then addresses why this happens: patient desperation, the placebo effect, and the sheer momentum of what has been called “Big Wellness”—an industry now worth hundreds of billions. Social media only amplifies these trends, creating fear of missing out and distorting what counts as credible.To help listeners navigate this landscape, Dr. Bobby shares questions to ask when encountering bold health claims. Has the treatment been proven in your condition? Are there peer-reviewed studies in humans? What are the risks and costs—not just financially, but in delaying evidence-based care? Are the promoters benefiting from those beliefs?He encourages all of us to remain open-minded skeptics: curious, informed, and protective of both our health and our wallets.Takeaways: Ask whether the health claim is backed by solid evidence, not just theory and anecdote. Don’t assume treatments with real uses are effective for everything they're marketed for. Before trying the latest therapy, ask: Is this proven for my condition, and what’s the real cost?
