Today's guest is Professor Charlotte Biltekoff, author, researcher, and lecturer at UC Davis. Dr. Biltekoff focuses on how good food became 'real' in the beginning of the 21st century and how the food industry has responded to increasingly negative public views of processed foods. She has turned her sights on ultra processed foods (UPFs) and the confusion on what they are and are not. Most important, she unpacks the history of how we got this point, with a large discussion about food science, food scientism, and naturalism. We end up having a discussion about the nature of knowledge and nutrition and how our cultural backgrounds really frame how we think about UPFs and food's goodness overall. As a scientist and policy maker, I learned so much from Charlotte, and I think you will too.
