What Not to Eat

Prof Tim Spector and Dr Kandi Ejiofor help us to navigate the world of ultra-processed foods. They reveal how some of the nation's favourite ultra-processed foods are made, and investigate exactly what ultra-processed foods are doing to our bodies.

Tim and Kandi reveal the science behind why biscuits are so moreish and find out how many chemicals are lurking in a simple slice of ultra-processed ham. They also help Nick and Sarah from Cambridgeshire to ditch their sausage rolls and boxed wine.

Tim and Kandi reveal what's found in the foods we eat every day, like breakfast cereals, and what's within some supermarket chicken nuggets. They also help Claire, Georgia and Jay with their diet that consists almost exclusively of beige food.

Tim and Kandi put diet drinks under the microscope to show us the chemicals that can be found within. They shock Frankie and Camille with the extent of their cola and crisp habit, and reveal the effect eating wholefoods can have on our health.
