Be Your Own Doctor

(Channel 4, 8.30pm-9pm)

Kate Quilton is joined by Dr Tamal Ray - known for his time on The Great British Bake Off last year - to investigate a series of questions about health, examining the latest online solutions to pressing medical needs and testing the boldest claims from recent advice. They examine whether eating placenta after childbirth can really revitalise the body faster, look at an app offering guidance on the status of moles and sun damage and try to discover what coconut pulling has to do with the perfect smile.
