In this episode of Longevity by Design, host Dr. Gil Blander sits down with Dalia Blander and Eprihm Blander, his parents, who are thriving in their nineties. Gil explores the daily routines, food choices, and mindsets that have kept Dalia and Eprihm active, independent, and healthy well into later life.

Dalia and Eprihm share how simple habits like regular movement, home-cooked meals, and a Mediterranean diet have shaped their health. They talk about the power of walking, gardening, and staying busy with meaningful work. Both value strong family ties and regular contact with friends, crediting these connections as key to their sense of purpose. Dalia highlights the importance of curiosity, reading, and keeping her mind sharp, while Eprihm stays engaged by helping with family business and learning new things.

Together, they show that a positive outlook, daily activity, and strong relationships are at the heart of a long, fulfilling life.

In this episode of Longevity by Design, host Dr. Gil Blander sits down with Dr. Emeran Mayer, Executive Director at the UCLA Center for Neurobiology of Stress and Resilience and founder of Mayer Interconnected. They explore the science behind the gut-brain connection and its role in shaping health and longevity.

Emeran explains how signals flow between the brain, gut, and microbiome, influencing everything from digestion to emotions. He breaks down how modern diets, especially ultra-processed foods, disrupt the natural balance between humans and gut microbes—a relationship refined over thousands of years. The conversation highlights why early life exposure to antibiotics can have lasting effects on microbiome resilience, and how lifestyle choices like diet and exercise remain powerful tools for supporting gut-brain health at any age.

The discussion closes with a look toward the future of gut-brain science, including engineered probiotics and the promise of more targeted therapies. Emeran shares practical habits for better gut-brain health and cautions against quick-fix “biohacking,” encouraging a return to whole foods, movement, and mindful living.

In this episode of Longevity by Design, host Dr. Gil Blander sits down with Dr. Albert-László Barabási, Professor at Northeastern University, to explore how networks shape health, aging, and nutrition. Barabási explains how biological and social networks influence resilience, robustness, and our ability to recover from stress or disease. He describes aging as a gradual loss of resilience, where the body becomes less able to bounce back from small disruptions.

The conversation moves into the world of nutrition, where Barabási introduces the concept of “nutritional dark matter.” He argues that food contains thousands of little-known molecules, many of which play key roles in health but remain largely unmapped and unstudied. Barabási breaks down how these compounds, especially those found in plants, support cellular function far beyond the traditional nutrients listed on food labels.

The episode closes with a look at ultra-processed foods and their link to disease risk. Barabási shares new research tools that can help people evaluate what they eat and make smarter choices. Throughout, he reminds listeners that strong connections, between cells, foods, and people, are at the heart of long, healthy lives.
