No Filter Doctor

Sunscreen recommendations have become increasingly confusing. Does sunscreen cause cancer? Are mineral sunscreens actually safer than chemical sunscreens? Does SPF 100 really provide more protection than SPF 30? And what is bemotrizinol, the new sunscreen ingredient recently approved in the United States after decades of use in Europe? In this episode of No Filter Doctor, I decode the science behind sunscreen so you can make informed decisions before spending time outdoors. We discuss UVA and UVB radiation, how sunscreen protects your skin, the differences between mineral and chemical sunscreens, SPF myths, concerns about ingredient absorption, and the evidence behind claims that sunscreen causes cancer. The goal isn't to tell you which sunscreen to buy. It's to help you understand the science so you can choose the sunscreen you're most likely to wear consistently.

In Part 1, we discussed what real parasitic infections look like, who is actually at risk, and how parasites are diagnosed. In Part 2, we examine the parasite cleanse industry itself. Why do parasite cleanse testimonials seem so convincing? What are "rope worms"? And what evidence actually supports the ingredients found in these products? We break down the difference between laboratory studies and human clinical trials, discuss the limits of supplement regulation, review potential risks associated with common parasite cleanse ingredients, and explore why social media claims often sound more convincing than the science behind them. While this episode focuses on parasite cleanses, the larger lesson is how to evaluate health claims, recognize weak evidence, and avoid being misled by persuasive marketing.

Parasite cleanses are everywhere right now, but before talking about the cleanses themselves, we need to start with a more important question: do you actually have a parasite? In Part 1 of this two-part series, I break down what parasites are, how common parasitic infections really are in the United States, who is actually at risk, and what real parasitic infections look like. We discuss common symptoms, exposure risks, diagnostic testing, and why vague complaints like fatigue, brain fog, sugar cravings, and difficulty losing weight are not typical presentations of known parasitic diseases. The goal of this episode is to help listeners understand the medical reality of parasitic infections before evaluating the claims made by the parasite cleanse industry.

Hantavirus has recently generated headlines and social media anxiety, with some people wondering whether this could become the next pandemic. In this episode of No Filter Doctor, I break down what hantavirus actually is, how it spreads, who is truly at risk, and why this is not COVID all over again. We discuss common misconceptions surrounding hantavirus, including transmission myths, panic driven messaging, and what the actual data shows about risk and spread. I also review symptoms, hantavirus pulmonary syndrome, mortality rates, treatment limitations, and why early symptoms are often mistaken for more common viral illnesses. The goal of this episode is not fear mongering or false reassurance. It is to provide an evidence-based framework so people can better understand what hantavirus is, what it is not, and when concern is actually warranted.

Dietary fiber does far more than help with constipation, yet most people still do not get enough of it. In this episode of No Filter Doctor, I break down what dietary fiber actually is, the differences between soluble and insoluble fiber, and why fiber plays such an important role in gut health, cholesterol regulation, blood sugar control, and long-term disease prevention. We also discuss the gut microbiome, short-chain fatty acids, fiber supplements, and practical ways to increase fiber intake without making yourself miserable in the process. The goal is not wellness hype or supplement marketing. It is to explain the actual physiology and evidence behind one of the most consistently under-consumed nutrients in modern diets.

Artificial intelligence is rapidly becoming part of everyday healthcare, from meal planning and fitness guidance to AI scribes and medical information platforms. But how reliable is it, and how should patients actually be using it? In this episode of No Filter Doctor, I’m joined by Resa E. Lewiss, M.D. to discuss the growing role of AI in health and medicine. We explore how patients are already using AI for nutrition, exercise planning, and health information, while also breaking down the limitations that many people do not understand. We discuss hallucinations, misinformation, prompt engineering, bias in healthcare datasets, environmental concerns surrounding AI, and the growing debate around de-skilling versus re-skilling in medicine and education. Most importantly, we discuss why AI should be viewed as a tool rather than an expert. This episode is designed to help listeners think more critically about how to use AI responsibly without overestimating its accuracy or capabilities. Read the full blog: AI to Get Healthy Guide

Over-the-counter medications are easy to buy, familiar, and often assumed to be the obvious first choice. But not every product on the pharmacy shelf is equally useful, and some are supported by much stronger evidence than others. In this episode of No Filter Doctor, I review common OTC medications that are worth rethinking. Some have limited evidence that they actually work. Some are effective but should only be used for a short period of time. Others may be reasonable medications, but not the best option available. And some are simply overpriced versions of cheaper alternatives. This episode covers common products used for congestion, cough, constipation, allergies, red eyes, earwax, minor wounds, itching, and pediatric fever or pain. The goal is not to scare people away from FDA approved medications. The goal is to help listeners make better informed decisions before spending money in the pharmacy aisle.

In Part 1, we examined how the research system can influence what gets published and promoted. In Part 2, the focus shifts to how individual studies are interpreted and how that interpretation is often distorted, particularly in wellness marketing. I’m joined again by Dr. Josh Davis, a medical research educator, to break down how study design, statistical framing, and data presentation can shape conclusions that sound convincing but may not reflect the full picture. We discuss how relative risk can exaggerate findings, why small or poorly designed studies are still frequently cited, and how selective reporting can create a narrative that supports a product rather than the underlying evidence. These are common tactics behind claims that are described as “backed by research.” This episode is designed to help you evaluate whether a study actually supports the claim being made, rather than simply accepting that a study exists.

Wellness influencers and companies often cite “studies” to support their claims. But not all research is created equal, and not everything labeled as a study should be trusted. In this episode, I’m joined by Dr. Josh Davis, a medical research educator who teaches medical students how to critically evaluate scientific literature. This is Part 1 of our discussion, where we focus on the systems behind research and why they matter when you are trying to decide what to trust. We break down how predatory journals, lack of true peer review, publication bias, and funding pressures can all influence what gets published and promoted. More importantly, we discuss how these issues are often leveraged in marketing to give products and treatments a sense of legitimacy they may not deserve. This is not about dismissing research. It is about understanding how to interpret it so you can separate meaningful evidence from material that is being used to sell you something. If you have ever seen a product backed by “studies” and wondered whether that actually means anything, this episode will give you a clearer framework for evaluating those claims.
