Скачать или смотреть Taste and Smell Preferences and Their Impact on Health with Dr. Yanina Pepino

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.

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.

Don't Be Fooled by "Zero-Calorie" Sweeteners

While considered safe, non-nutritive sweeteners might have unintended consequences for our metabolism. Yanina's work suggests that these sweeteners, despite lacking calories, can still impact insulin response and potentially contribute to insulin resistance. This emphasizes that these artificial sweeteners are not a free pass for a sweet tooth. Moderation and prioritizing natural sugars in limited amounts remain crucial for metabolic health.

Why Diets Fail: It's Not Just Willpower

Losing weight through lifestyle changes alone can feel like an uphill battle. Yanina explains that it's not simply a lack of willpower but a complex interplay of biological factors. Once we gain weight, particularly fat, our metabolism changes, making it harder to control hunger. Bariatric surgery and GLP-1 agonists offer an advantage by directly addressing those hunger signals, providing a window to establish healthier habits.
"It is very difficult. It doesn't mean it cannot be doable. A lot of people can do it, they lose weight, and they're able to keep it off, but the problem is that once a person gains body weight — in particular, once you gain fat — there are a lot of things in the metabolism that make it very difficult to tame your hunger."
