Best TV Tonight: Michael Mosley: Secrets of Your Big Shop

Michael Mosely: Secrets of Your Big Shop is new to Channel 4. Watch it tonight at 8pm or stream it on demand.

In this fresh series, Dr. Michael Mosley delves into the nation's health, exploring the contents of our shopping carts. Sixty percent of non-genetic illnesses are linked to our diet, and Michael is determined to make a significant impact.

Going incognito in supermarkets nationwide, he investigates our purchasing habits and their impact on our well-being. In the initial episode, we meet Chris, a lorry driver from Kent, and his wife Rebecca, an NHS worker.

Despite their commitment to healthy eating, cooking from scratch, and a fondness for broccoli, Chris manages blood pressure and cholesterol with medication, while Rebecca battles unexplained fatigue. Revealing their shopping choices to Dr. Michael during his undercover checkout mission, he unravels the potential reasons behind Rebecca's tiredness and then revamps the couple's diet.

The episode also features Dr. Michael's exploration of a viral TikTok recipe for 'healthifying' cola and his insights on the topic of snacking.
