We all want to eat healthier. The Paleo diet promises exactly that: eat like our ancestors, avoid modern foods, and improve your health. But does it really support your gut, heart and long-term health, or is the story more complicated? In this episode, Dr James Cole, a world-leading expert on prehistoric diets, joins Dr Federica Amati to explore what Paleo gets right and why some of the claims may be dangerously wrong. James explains what ancient evidence tells us about human diets, why the modern-day Paleo diet may go too far in its restrictions, and what that might mean for your heart disease risk and gut health. By the end of the episode, you’ll have ideas on what principles to keep from the Paleo diet, and what rules to avoid. Could trying to eat as our ancestors did force you to cut foods your body actually needs? Before you give up grains, beans or dairy, it may be worth asking what ancient humans really ate. 🌱 Try our science-backed and tasty wholefood supplement Daily30 🌿Let your gut microbes snack on the ZOE Gut Health Bar Get our brand-new app and Gut Health Test designed by world-leading gut health and nutrition scientists to build healthy eating habits 👉 Join ZOE Follow ZOE on Instagram.
