Ultra-processed foods now make up over half of what many of us eat - and the health consequences are only just coming into focus. In this episode, we reveal what’s really happening inside your body when you eat these foods daily.

Our guest is Dr. Andy Chan, a Harvard professor and leading expert on gut health and cancer prevention. He heads the Clinical and Translational Epidemiology Unit at Massachusetts General Hospital and has published over 400 scientific papers.

Dr. Chan breaks down the hidden links between UPFs, inflammation, and diseases like obesity, diabetes, and colorectal cancer. You’ll hear why some foods that look healthy on the shelf may be doing long-term damage - and how the gut microbiome plays a crucial role in the process.
