The Evidence

Salt

As a flavouring and preservative in food, as saline solution in medical and health care and in so many other forms, we encounter salt in our day-to-day lives without giving it much thought.

Join Claudia Hammond and a panel of scientists and experts, including Professor of Chemistry Andrea Sella, Professor Dike Ojji, a researcher in heart disease and blood pressure, Health Economics Professor Céu Mateus as they discuss the role of salt in our lives and food historian Pen Vogler.

The audience will have the chance to ask questions afterwards. You can participate or just listen in. 

The event will be recorded live with an audience and edited into a programme to be broadcast on the BBC World Service as part of ‘The Evidence’ series. After broadcast, episodes of ’The Evidence’ will be available on the BBC website.

Join Claudia Hammond and guests for a recording of the BBC radio series 'The Evidence' as they examine the importance of common salt in our lives.
