In the second episode of Medicine made for you we’re looking at the food we eat and how dietary advice could soon get a lot more personalised. 

Listen to our producer Gemma Ware go through a two-week experiment with her identical twin sister, aimed at trying to better understand which factors influence the way people react to particular foods. The PREDICT study involved eating lots of special muffins, and doing lots of blood tests. But the results are surprising – and show that everybody reacts differently to different foods, even identical twins.

We also explore what role a person's microbiome has in their health and whether it will ever be possible to personalise dietary advice based on the bacteria in your gut. And we look at wider questions about what kind of personalised nutritional advice actually gets people to change their behaviour.

Featuring interviews with Professor Tim Spector from King's College London and Professors Glenn Gibson and Julie Lovegrove at the University of Reading.

The music in this episode is Is That You or Are You You? by Chris Zabriskie and Hallon by Christian Bjoerklund. Medicine made for you is produced and reported by Holly Squire and Gemma Ware, and hosted by Annabel Bligh for The Anthill podcast.
