Bridging Research and Policy in Global Nutrition | Purnima Menon, PhD
How do we turn cutting-edge nutrition research into policies that improve people's lives? In this episode of The Ty Beal Show, Purnima Menon, PhD, Senior Director of Food and Nutrition Policy at IFPRI, shares her journey from reading recipe books as a child to becoming a world leader in advancing global nutrition at the intersection of science and policy.
Purnima explains why understanding people—their constraints, motivations, and contexts—is essential to creating meaningful change in food systems. We discuss the challenges of siloed thinking in nutrition, the complexities of sustainable diets, and what it takes to bridge the gap between evidence and action. Purnima brings a deeply human-centered perspective to some of the most pressing questions in food systems transformation.
Highlights from the episode include:
Why understanding people is central to all nutrition change—whether in behavior, programs, or policy
The biggest challenges facing global nutrition today and why we need to move beyond siloed solutions
How dietary choices are shaped by structural constraints at the intersection of water, energy, food, and gender
What it takes to bridge research and policy—and why both matter
The role of policy incentives and political economy in transforming food systems
Dr. Menon brings decades of experience working with influential researchers and policymakers around the world, offering a nuanced perspective that connects evidence to real-world impact. Her work reminds us that privilege comes with responsibility—and that meaningful change requires joining the dots between science, people, and policy.

Muscle Health, Protein, and Longevity | Stuart Phillips, PhD
How much protein do we really need? And is resistance training more important than we thought? In this episode of The Ty Beal Show, Stuart Phillips, PhD, renowned expert in muscle health and aging at McMaster University, breaks down the science of muscle preservation across the lifespan.
Stuart shares his evolving perspective on protein's role in building and maintaining muscle, explaining why exercise is the true driver of muscle development—and why the current Recommended Dietary Allowance may be setting the bar too low. We discuss optimal protein intake for different life stages, the nuances of plant-based versus animal-based proteins, and why strength training matters far more for longevity than most people realize.
Highlights from the episode include:
Why exercise, not protein alone, is the key to preserving muscle as we age
The difference between strength and power—and why power matters most for preventing falls and maintaining independence
Evidence-based resistance training: what works and how much time you really need to invest
The RDA for protein versus optimal intake—and why the distinction matters globally
Protein requirements across life stages: pregnancy, childhood, older adulthood
Plant-based versus animal-based proteins: separating science from ideology
Safe protein intake ranges for longevity and health
What older adults should prioritize to maintain muscle and function
Dr. Phillips brings a refreshingly balanced perspective grounded in decades of rigorous research—pushing back against both protein minimalism and protein extremism to reveal what the evidence says.

Can grazing livestock help restore soils, support biodiversity, and even mitigate climate change? In this episode of The Ty Beal Show, rangeland ecologist at Colorado State University, Dr. Paige Stanley, shares her research on regenerative grazing systems and their potential to benefit both landscapes and livelihoods.
Paige explains how well-managed grazing influences soil carbon dynamics, plant communities, and ecosystem resilience—and why not all grazing systems are created equal. We discuss the science behind methane emissions from cattle, trade-offs in land use, and how policy and incentives can help expand regenerative ranching practices that balance productivity with environmental stewardship.
Highlights from the episode include:
• How regenerative grazing differs from conventional grazing and why management matters
• What the latest research says about grazing’s role in soil carbon sequestration and biodiversity
• The methane puzzle—short-lived climate pollutants and strategies to reduce emissions
• Opportunities and challenges in scaling regenerative ranching for both ranchers and policymakers
Paige brings a nuanced, evidence-based perspective on the role of grazing animals in sustainable food systems—cutting through polarized debates with insights from the field.

Understanding OCD and Evidence-Based Treatment | Sara Brungardt, PhD, LPC
What exactly is obsessive-compulsive disorder (OCD)—and how can evidence-based therapies help people reclaim their lives? In this episode of The Ty Beal Show, Dr. Sara Brungardt, licensed professional counselor and founder of CalmOCD, shares her expertise on diagnosing and treating OCD with proven methods like Exposure and Response Prevention (ERP) and Acceptance and Commitment Therapy (ACT).
Sara explains how OCD differs from perfectionism or personality traits, why intrusive thoughts don’t define a person’s character, and how therapy can rewire the brain’s fear response. We also discuss common myths about OCD, overlaps with eating disorders and anxiety, and how families can best support loved ones navigating recovery.
Highlights from the episode include:
What distinguishes OCD from ordinary worries or habits
How ERP and ACT work to reduce compulsions and anxiety
The connection between OCD, eating disorders, and control
Practical advice for supporting someone with OCD or seeking treatment
Dr. Brungardt offers a compassionate, science-based perspective that brings clarity to a misunderstood condition—and hope to those living with it.

U.S. Food Politics and Rethinking Chronic Disease | Calley Means
Why do so many U.S. nutrition and health policies seem to favor ultra-processed foods over real, nutrient-dense foods—and what can be done about it? In this episode of The Ty Beal Show, Calley Means—New York Times #1 best-selling author, co-founder of Truemed, and Senior Advisor to the White House on MAHA—unpacks the structural incentives driving chronic disease in America.
Calley draws on his experience as a former political consultant for food and pharmaceutical companies to reveal how lobbying and reimbursement systems shape the foods we eat and the treatments we receive. We discuss how misaligned incentives fuel the epidemic of obesity and metabolic disorders, why prevention remains undervalued, and what reforms could redirect billions toward truly health-promoting foods.
Highlights from the episode include:
How Big Food and Big Pharma shape nutrition guidelines and healthcare spending
The impact of ultra-processed foods on children’s health and chronic disease risk
Policy and market innovations—like food-as-medicine—that could shift incentives toward prevention
Practical steps for individuals and policymakers to support healthier food environments
Calley shares an urgent, insider’s perspective on how policy and industry can change to address the root causes of metabolic disease rather than merely treating symptoms.
