From Vitamin C and fruit-flavoured sherbet, to the chemicals adding flavour to ultra-processed foods - Sheila Dillon delves into the world of food additives, to learn about the impact E Numbers have had on modern diets.

Sheila meets with food scientist and entertainer Stefan Gates, for some entertaining and surprising E Number experiments in his lab-kitchen...

She also hears more about the background to food additives from Stacey Lockyer at the British Nutrition Foundation; and explores some of the impacts, questions and controversies around these added extras, with gut microbiome expert Professor Tim Spector, and science policy professor Erik Millstone.

Following this introduction to the world of additives, The Food Programme invites listeners to get in touch and share their questions and thoughts on these ingredients, ahead of a panel discussion on the role of additives in our everyday lives, taking place in front of a live audience next week.
