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.
