Why You Can’t Stop Eating Ultra-Processed Foods: Dr Chris Van Tulleken


Why do we all eat stuff that isn’t food and why can’t we stop? In this episode, Dr Chris van Tulleken, author of Ultra-Processed People explains all. As well as being one of the UK’s leading science broadcasters, Chris is a practising infectious diseases doctor in the NHS. He gained his medical degree at Oxford University and his PhD in molecular virology from University College London, where he is an associate professor. He works closely with the World Health Organization and UNICEF, and his research looks at how corporations affect human health.

In this episode, Chris explores what may be the biggest public-health crisis of our time: ultra-processed food, or UPF, for short. Many people these days, certainly most regular listeners to this podcast, will be aware of UPFs. But there’s still a lot of confusion around what they really are. For Chris, it’s simple: if it’s wrapped in plastic and has at least one ingredient you wouldn’t find in a home kitchen, it’s a UPF. If it makes a health claim on the packet? Ironically, it’s even more likely!

A UPF is any food that’s processed industrially and created for big-business profit, rather than to provide nutrients. And here in the UK, UPF makes up 60 percent of the average diet.  The trouble is, says Chris, UPFs have been shown to be the leading cause of early death in the world, ahead of tobacco. Even if you remain at what is considered a healthy weight, consuming UPFs still leaves you vulnerable to things like Type 2 Diabetes, heart disease, dementia, anxiety, depression, inflammatory bowel disease, cancer and eating disorders.

In this conversation, Chris provides a clear definition of the difference between processing and ultra-processing, and explains how our toxic food environment is designed to be addictive.  We also discuss a whole range of different topics such as the need to see obesity as a condition and not an identity and the seemingly revolutionary idea that re-prioritising food shopping and cooking as a vital, enjoyable part of our day, could be a first step towards the societal change that’s urgently needed.

This podcast episode is not about shame or blame – it’s about education and empowerment. Chris is a brilliant communicator who insists the prevalence and appeal of UPFs is not our fault. I thoroughly enjoyed my conversation with him – I hope you enjoy listening.
