In this episode, we delve into the concept of being "qualified" in the workplace, examining who gets labeled as such, who doesn't, and the underlying reasons. We explore "competency checking"—the practice of scrutinizing individuals' abilities—and how it disproportionately affects underrepresented groups, often going unnoticed or unchallenged. Our discussion aims to redefine qualifications in a fair, equitable, and actionable manner. Our guest, Shari Dunn , is an accomplished journalist, former attorney, news anchor, CEO, university professor, and sought-after speaker. She has been recognized as Executive of the Year and a Woman of Influence, with her work appearing in Fortune Magazine, The Wall Street Journal, Ad Age, and more. Her new book, Qualified: How Competency Checking and Race Collide at Work , unpacks what it truly means to be deserving and capable—and why systemic barriers, not personal deficits, are often the real problem. Her insights challenge the narratives that hold so many of us back and offer practical solutions for building a more equitable future. Together, we can build workplaces and communities that don’t just reflect the world we live in, but the one we want to create. A world where being qualified is about recognizing the talent and potential that’s been overlooked for far too long. It’s not just about getting a seat at the table—it’s about building an entirely new table, one designed with space for all of us.

Understanding the complexities of diet-disease relationships requires a nuanced approach to nutritional science. Unlike other scientific disciplines, nutrition research often grapples with the inherent challenges of studying dietary patterns and nutrient intakes in free-living populations over long periods. The cumulative effects of dietary exposures, combined with the necessity to control for confounding factors such as total energy intake and population-specific dietary habits, highlight the need for rigorous study designs and careful interpretation of findings. Despite their utility, these methods are often misunderstood or misrepresented in public discourse. Addressing these misunderstandings requires a clear communication of key principles underpinning nutritional science, including the role of cumulative exposure, the importance of contextualizing absolute and relative risks, and the necessity of evaluating the long-term effects of dietary patterns. This episode aims to provide a comprehensive overview of these essential ideas, equipping readers with the tools to critically appraise the evidence and engage meaningfully with the ongoing conversation around nutrition research.

Multivitamin Nihilism: Is it Actually Worthless to Supplement? (SNP37) 17:39

۵ weeks پیش17:39

17:39

Multivitamin and multimineral supplements have long been a topic of both scientific inquiry and public debate. While they are often marketed as convenient solutions for achieving nutritional adequacy, their true value remains contentious. Are these supplements essential insurance policies against nutrient deficiencies, or are they merely expensive placebos? Importantly, how should we weigh their potential benefits against the lack of robust evidence for long-term health outcomes such as reduced mortality or chronic disease risk? These questions demand a nuanced exploration, grounded in the context of specific populations and individual needs. Ultimately, the role of multivitamin supplements cannot be assessed in isolation but must be viewed through the lens of context and specificity. How do we balance the biological plausibility of benefits against the variability of individual diets, the presence of fortification policies, and the challenges of achieving dietary adequacy in certain life stages? These considerations invite a more thoughtful and less binary discussion about whether, when, and for whom multivitamins are a worthwhile addition to the diet.

In the realm of nutrition science, individual differences are more profound and impactful than many realize. For decades, we’ve developed dietary recommendations with a “one-size-fits-all” approach, assuming that most people respond similarly to specific nutrients. But Dr. Martin Kohlmeier, a pioneer in precision nutrition, challenges this very notion. How might an individual’s genetic makeup alter their need for certain nutrients? With advances in nutrigenetics, we’re beginning to see how personalized nutrition could bridge long-standing gaps in dietary efficacy. Dr. Kohlmeier’s work highlights fascinating examples, from the APOE4 gene’s influence on cholesterol metabolism to variations in folate metabolism that could affect everything from heart health to birth outcomes. As Dr. Kohlmeier explains, precision nutrition is not simply about adding genetic testing to a wellness regimen. Instead, it requires rethinking nutrition research from the ground up—ensuring studies capture these individual variations and that public health policy moves beyond broad averages. With genetic testing now more accessible than ever, could commercial pressures and oversimplified testing derail the science before it even gets going? In this episode, we dive deep into the potential and pitfalls of precision nutrition, exploring the future of personalized dietary advice and the road to truly individualized health.
