Chris and Xand take a closer look at cholesterol - what it is, why it worries so many people, and how diet and medicine fit into the picture. They’re joined again by Professor Nita Forouhi, Professor of Population Health and Nutrition at the University of Cambridge, to discuss why foods like seed oils become controversial, when cholesterol-lowering drugs such as statins make sense, and how her thinking on cholesterol has evolved over her career.
