Longevity on Your Plate: The Role of Diet in Aging and Healthspan with Dr. Cristal M. Hill, USC

Emerging research emphasizes the impact of caloric intake, macronutrient composition, and dietary patterns on aging and longevity. Caloric restriction and intermittent fasting have been associated with extended lifespan and delayed onset of age-related diseases by promoting cellular repair mechanisms and metabolic efficiency. Additionally, diets rich in plant-based foods, healthy fats, and lean proteins—such as the Mediterranean and Blue Zone diets—have been linked to improved longevity and reduced risk of chronic conditions like cardiovascular disease, diabetes, and neurodegenerative disorders. Conversely, diets high in processed foods, refined sugars, and unhealthy fats contribute to inflammation, oxidative stress, and shortened lifespan. This talk with review established mechanisms through which diet influences aging, including molecular pathways and metabolic regulation to extend lifespan. Understanding the relationship between nutrition and longevity can inform dietary recommendations and interventions aimed at promoting healthier aging and extended lifespan. **This presentation is made possible by the LSAC DEIR Grant**
