Can we Slow the Speed of Aging? Biological Age & Epigenetics - Varun Dwaraka, PhD

Can we slow the speed of aging? In this episode, Dr. Varun Dwaraka, Head of Bioinformatics at TruDiagnostic, walks us through through the science of measuring "biological age" using epigenetic markers, such as DNA methylation. We discuss how epigenetics (i.e. DNA methylation), may provide biomarkers of biological age, the rate at which aging occurs, and potentially early markers of disease. Dr. Dwaraka explains the distinctions between chronological and biological age, the development and refinement of epigenetic clocks, and the potential applications of these tools in aging interventions. The conversation also addresses the mechanisms of epigenetic regulation, the influence of lifestyle factors on biological age, and the future role of epigenetics in predicting and managing age-related diseases. Additionally, we examine the data science that underpins these clocks, their targeted outcomes, and a recent study published by Dr. Dwaraka and colleagues comparing aging biomarker outcomes in a vegan vs. omnivore diet intervention among twins.
