Could a digital doppelganger predict how food and medicine affect your body?

How digital DNA could help you make better health choices | Jun Wang · 14:55 · Video: TED · Watch at the source

In short: Genomics researcher Jun Wang explores the potential of using genetic code and real-time biological data to create digital twins that simulate your personal health responses.

The video examines the development of 'digital doppelgangers' designed to model individual health. By integrating genetic information with diverse data streams—including sleep patterns, nutritional intake, and even metrics from a 'smart toilet'—Wang aims to build an engine capable of predicting how specific medications or foods will impact a person's health before they are even consumed.
