On this episode of Longevity by Design, Dr. Gil Blander speaks with Dr. Michael Ringel, COO of Life Biosciences, about the science of aging and longevity. Michael discusses how evolution influences lifespan and why aging occurs. He explains the trade-off between resource allocation for reproduction versus maintenance and repair within the body. Caloric restriction and its effects on lifespan are explored through an evolutionary lens.

Michael highlights the challenges and breakthroughs in longevity research. He touches upon the role of genetics and pharmaceuticals in manipulating lifespan and healthspan. He points to the Pacific rockfish as an example of varying lifespans within a closely related group of species, demonstrating the genetic component of aging. He also notes the impact of Cell reprogramming, referencing a study on how specific Cell reprogramming can regenerate optic nerves.

The conversation shifts to the business of longevity, where Michael discusses the increased interest and investments from big pharma and billionaires. He examines the economic benefits of extending healthspan, citing a potential value of $300 trillion from a 10-year healthspan extension in the US alone. Michael and Gil also explore the importance of lifestyle choices for healthy aging, emphasizing diet, exercise, sleep, stress management, and social connections.

On this episode of Longevity by Design, Dr. Gil Blander welcomes Dr. John Erdman to discuss prostate cancer and the impact of diet on disease progression. John shares his personal connection to this disease and why he’s dedicated his research to understanding dietary interventions.

John explains that prostate cancer is often slow-growing, with most men experiencing decades between early mutations and noticeable tumor growth. He stresses the importance of early detection through regular checkups, including digital exams and PSA tests. While the medical community debates the effectiveness of these tests, John advocates for establishing a baseline to monitor for any sudden changes.

John's research reveals a strong link between tomato consumption and reduced prostate cancer risk. He believes this protective effect stems from lycopene and its metabolites, which may influence gene expression. John emphasizes that while tomato consumption shows promise, maintaining a healthy weight and regular exercise are equally crucial for long-term health.

Not all Fermented Foods Are Equal

While many cultures around the world have enjoyed the benefits of fermented foods for centuries, modern consumers need to be savvier about what they’re buying. Just because a food is fermented or contains live cultures doesn’t mean it offers proven health benefits. The term "probiotics" is specifically defined and requires scientific evidence to support health claims, so don’t be afraid to read labels carefully and choose fermented foods backed by research.

Lactic Acid Fermentation May Be a Key Player in Health

While there are many types of fermentation, lactic acid fermentation, which is responsible for foods like yogurt, kimchi, and sauerkraut, is of particular interest to researchers. Early studies show promising links between consuming lactic acid-fermented foods and positive impacts on gut health, immune function, and even potentially longevity. The specific mechanisms are still being investigated, but it seems these foods offer more than just interesting flavors.

Scientists Are Unlocking the Power of Postbiotics

Scientists are going beyond probiotics and exploring the potential of “postbiotics” – those beneficial compounds produced by bacteria during fermentation. These metabolites may hold the key to unlocking even more targeted health benefits from fermented foods. Dr. Allen and Dr. Miller’s research on aryl lactates, for instance, suggests that some postbiotics could help modulate immune responses and address inflammation. This area of study is rapidly evolving and offers an exciting frontier in food science and human health.

The History and Significance of Fermentation

Long before refrigeration, humans discovered the magic of fermentation. This process, dating back thousands of years, involves harnessing the power of microbes to transform food. What began as a way to preserve food has evolved into an art form, with diverse cultures developing unique fermentation traditions that add flavor and depth to their cuisines.
"A lot of these fermentation practices keep foods for a much longer period of time without refrigeration and we did not have refrigeration until 100 years ago." - Dr. Jacob Allen

Understanding the Difference: Probiotics vs. Live Cultures

While often used interchangeably, “probiotics” and “live cultures” have distinct meanings. Probiotics refer to specific strains of live microorganisms scientifically proven to provide health benefits when consumed in adequate amounts. In contrast, “live cultures” indicate the presence of live microbes in food but don't guarantee specific health benefits without further research.
“Probiotics are things that have documented clinical evidence. Live cultures, on the other hand, are you eating live microorganisms.” - Dr. Mike Miller

On this episode of Longevity by Design, Dr. Gil Blander welcomes Dr. Yanina Pepino, Professor of Ingestive Behavior at the University of Illinois, to discuss the fascinating link between taste, personal preferences, and long-term health. Yanina's research shows our food environment significantly shapes cravings. This exposure starts as early as the womb, impacting future preferences.

Yanina explains that bariatric surgery and GLP-1 medications are powerful tools for weight management. However, she emphasizes the importance of using these interventions as opportunities to adopt healthier eating habits. She highlights the potential of GLP-1 agonists as a treatment for alcohol use disorder, noting their ability to reduce alcohol cravings.

The conversation also explores the impact of non-nutritive sweeteners. While generally considered safe, Yanina's research suggests that these sweeteners may have metabolic effects. She encourages listeners to be mindful of their intake and to prioritize natural sugars in moderation.

Episode highlights:

• Introduction: 00:00:00
• Why have you decided to be a scientist: 00:03:40
• How did you get interested in the taste & smell preference in humans: 00:04:40

• Lessons from the COVID-19 Pandemic on Taste and Smell Perception: 00:54:30
• Yanina's top tip for healthspan: 00:42:10

Early Taste Exposure Shapes Lifelong Preferences

What we eat during pregnancy and infancy might pre-program a child's future food preferences. Yanina's research reveals that exposure to flavors, even in the womb, can influence what we enjoy eating later in life. This highlights the importance of establishing healthy eating patterns from the very beginning, as those early experiences can have lasting effects. Parents and caregivers have a powerful role in shaping those early preferences for a healthier future generation.

Bariatric Surgery and GLP-1 Offer a Chance to "Reset"

Both bariatric surgery and GLP-1 medications are not just quick fixes, but opportunities to rewire your relationship with food. While these interventions can significantly impact hunger hormones and promote weight loss, their long-term success relies on behavioral change. Yanina stresses the importance of using this period of altered appetite to explore new, healthier food choices and establish lasting dietary habits.

 The Evolution of the Nutrition Deep Dive

InsideTracker's Nutrition Deep Dive was a decade-long project aimed at solving the challenge of personalized nutrition. Dr. Blander explains that the project began with the realization that no one had figured out how to match the right food with the right person at the right time. The team worked extensively, developing multiple iterations, collaborating with leading scientists, and employing cutting-edge technology, including food recognition platforms and barcode readers. Despite the prolonged process, their persistence led to a comprehensive solution that analyzes user input, such as food consumption and biomarker data, to offer personalized nutritional insights.

Food Tracking Technology: A Game-Changer

One of the most exciting aspects of InsideTracker’s Nutrition Deep Dive innovation is its food recognition technology. Users can log food through various methods, including scanning barcodes or using their iPhone camera to identify food items. The system is capable of analyzing over 4,000 foods, and the database is continuously expanding. This ability to gather real-time nutrition data revolutionizes how users can assess their diet. When paired with data from fitness trackers, the insights help to better understand the connection between food, sleep, exercise, and overall performance, thus optimizing health.
