How did ultra-processed foods take over, and what are they doing to us

Dr Chris van Tulleken provides a fascinating insight into the history of ultra-processed food (UPF), how they are made, why they are so addictive, how they have become a major part of our diets and the impact they are having on the global obesity crisis. Having experimented himself with an 80% UPF diet for a month he knows first-hand the detrimental impact that these foods had on his health and eating habits. Key drivers for increased UPF consumption are thought to be largely attributed to marketing, poverty and inequality.
