Processed food is everywhere—and chances are, you're eating more of it than you think. In this episode of Unfold, we go beyond the ingredient list to uncover the science and public perceptions of processed and ultra-processed foods. Are these foods addictive by design, unsafe or just misunderstood? With insights from food scientists and cultural experts, we’ll examine how modern food manufacturing may be shaping our health, our public policy and even our understanding of what food is.
