Chris van Tulleken, born in 1978, is a British physician, academic, writer and television presenter – known to a fair chunk of the country simply as Dr Chris. He is the identical twin of Xand van Tulleken, whose career in global and public health has run along similar lines, and the pair have jointly presented programmes including The Doctor Who Gave Up Drugs, the children’s series Operation Ouch! and the podcast A Thorough Examination.
His investigation of dietary causes of disease produced Ultra-Processed People, a Sunday Times best-seller – the moment his work jumped from the television schedules into the national conversation about what we actually eat.
