Well informed: which foods should you avoid?

The internet is awash with clever fitness hacks, fad diets and home remedies that claim to help you live a longer, healthier and happier life. But how well do these promises hold up to scientific scrutiny? And what about the vices you’re told to avoid? This week, our correspondents consider the evidence on three types of food that have been linked to health concerns: butter, ultra-processed foods and red meat. How bad for you are they, really?

This episode is part of our new “Well informed” series on Babbage. Every few months we’ll scrutinise the evidence behind some of the health or wellness trends making headlines. 

Host: Alok Jha, The Economist’s science and technology editor. Contributors: The Economist’s Ainslie Johnstone, Shailesh Chitnis and Slavea Chankova.
