Are some of your "healthy" foods actually high-risk ultra-processed foods? For decades, nutrition advice seemed relatively straightforward. Eat less sugar. Less salt. Less saturated fat. Then it all fell apart. In today’s episode, we examine the research that has forced us to rethink what makes food harmful in the first place. Two of the world’s leading nutrition scientists, Professor Tim Spector and Professor Sarah Berry, tell their own story of why they’ve changed their minds about it. We explore why sugar, salt and fat aren’t the whole story, explain why ultra-processed foods are making us sick, and share groundbreaking insight that only a small portion of them are really harmful. By the end of the episode, you’ll know what to watch out for and what to worry less about when you’re food shopping. Next time you reach for a "healthy" yogurt or a quick pasta sauce, would you still choose it if you knew exactly how it was made? 🌱 Try our science-backed and tasty wholefood supplement Daily30: https://zoe.com/daily30?utm_medium=zoe_podcast&utm_source=youtube&utm_campaign=d30 🌿Let your gut microbes snack on the ZOE Gut Health Bar | https://zoe.com/snackbar?utm_medium=zoe_podcast&utm_source=youtube&utm_campaign=GHB Build healthy habits.
