Zoe Harcombe didn't set out to become a controversial figure in nutrition science. With a background working inside both Mars candy company and pharmaceutical giant GlaxoSmithKline, she witnessed firsthand how corporate interests shape public health messages. But when she decided to pursue her PhD, what she discovered about the origins of our dietary guidelines shocked even her.

In this revealing conversation with Dr. Philip Ovadia, Harcombe breaks down her groundbreaking research showing that America's low-fat dietary guidelines - the foundation for nutritional advice affecting hundreds of millions of people - were based on just six randomized controlled trials involving fewer than 2,500 exclusively sick men.

But this isn't just about diet. Harcombe also shares her five-year legal battle against a major UK newspaper that attempted to silence her criticisms of statin research through personal attacks rather than scientific debate.
