Welcome to What’s Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken untangle the confusion around every aspect of our health and wellbeing.

In this episode, they want to get to the bottom of the hype around protein. Should we be worried about not getting enough? What are the best sources of protein? And are protein supplements fact or fad? They speak to Nita Forouhi, Professor of Population Health and Nutrition at the University of Cambridge, to find out.
