Today we’re diving into the world of artificial sweeteners.

Back in July 1982, Coca-Cola launched a groundbreaking new product: Diet Coke. A healthier alternative for those Coke fans looking to cut back on sugar and manage their weight. Sounds great, right? Well, maybe not.

You see Diet Coke, and many other low sugar drinks, rely on artificial sweeteners. And while they were once seen as a smart swap, emerging research is raising serious concerns about their long-term effect on our health.

In this episode, I’m joined by Professor Eran Elinav and Professor Tim Spector to break down the latest science and explore how these sweeteners impact our gut microbiome.
