Is Dairy Hurting Your Brain Health?

Plant-based nutrition, brain health, and healthy aging are becoming some of the most important conversations in modern wellness and preventive healthcare. In a world filled with conflicting nutrition advice, high-protein diet trends, and growing chronic disease rates, many people are searching for sustainable, science-backed ways to improve their health, reduce inflammation, support cognitive function, and live longer, healthier lives. 

In this episode, Dr. Supatra Tovar sits down with clinical nutrition researcher and educator Dr. John Lewis for a powerful conversation about plant-based nutrition, longevity, brain health, inflammation, dairy consumption, animal protein, and lifestyle medicine. Together, they explore how nutrition affects the body at every level, from digestion and metabolic health to cognitive aging and disease prevention.

Dr. John Lewis shares insights from decades of research and over 180 peer-reviewed scientific publications focused on nutrition science, healthy aging, exercise, dietary supplementation, and cognitive health. The conversation explores the myths surrounding dairy and calcium, the risks associated with excessive animal protein consumption, insulin resistance, inflammation, osteoporosis, whole grains, and why sustainable wellness habits matter more than restrictive dieting or extreme health trends.

You’ll also hear thoughtful discussions about modern nutrition misinformation, the cultural obsession with protein, the rise of anti-plant-based rhetoric, and how whole-food plant-based nutrition may support brain health, longevity, digestion, and long-term wellness. Dr. Tovar and Dr. Lewis also discuss practical ways people can make small nutrition changes that support healthier aging and a better relationship with food and health overall.

If you’ve ever wondered how nutrition impacts inflammation, cognitive health, chronic disease risk, healthy aging, or overall longevity, this conversation offers practical insights grounded in both science and real-world application.
