Most replayed moment: Is Our Food System Making Us Sick? | Prof Brian Elbel & Prof Tim Spector

This episode of Zoe Science & Nutrition explores how the modern food system—driven by ultra-processed foods and industrial food engineering—is fundamentally reshaping public health. Professors Brian Elbel and Tim Spector discuss the rise of ultra-processed foods (UPFs), which now make up 50-60% of the Western diet, and how their hyper-palatable, factory-made formulations are designed to trigger overeating and long-term health decline. The hosts emphasize that these foods are not just unhealthy due to additives, but because of their engineered structure, rapid consumption speed, and psychological appeal. The conversation shifts from critique to action, highlighting the Zoe app’s new five-tier classification system for UPFs, which goes beyond simple ingredient lists to assess real-world health risks. The experts also advocate for systemic change, including food taxes, marketing restrictions, and school food reforms, arguing that individual choices alone are insufficient against such a pervasive system. Finally, the episode transitions to menopause, with a spotlight on Zoe’s groundbreaking research showing that dietary changes can reduce menopause symptoms by up to 37%.
