Dr. Chris Van Tulleken is an infectious disease doctor, academic researcher, and popular television presenter best known for hosting science programs, such as  on the BBC and Channel 4. Born in the UK in 1978, Van Tulleken studied medicine at the University of Oxford before completing a PhD in molecular virology at University College London. He went on to work as a doctor with 'Doctors Without Borders', in locations such as rural Africa. Dr. Van Tulleken hosted acclaimed science documentaries such as: Medicine Men Go Wild, Trust Me I'm a Doctor, The Doctor Who Gave up Drugs, and What Are We Feeding Our Children?  Through his broadcasting work, Van Tulleken became increasingly concerned about the impacts of processed and ultra-processed foods on human health. This prompted him to write his first book, 'Ultra-Processed People: How Modern Food is Killing Us and What We Can Do About It.' Published in 2022, his book examines the science linking ultra-processed foods to problems like obesity, addiction, and depression. It also explores the environmental impact of industrial food processing and offers solutions to help people and policymakers make healthier choices.  The content of our show is educational only.
