Channel 4’s ‘What Not to Eat’ Tackles Ultra-Processed Foods Crisis

New Series Aims to Transform Britain’s Eating Habits

Channel 4 has launched a four-part health series fronted by award-winning scientist Professor Tim Spector with Dr Kandi Ejiofor, helping the UK navigate the baffling world of ultra-processed foods (UPFs), thought to directly contribute to the UK’s rising obesity rates. The show premiered on Tuesday 6 January, offering viewers crucial insights into what they’re really consuming.

Why This Show Matters Now

Ultra-processed food is everywhere – cheap, convenient and often marketed as healthy – yet most consumers remain unaware of its impact on their health. Professor Spector highlights how seemingly healthy ‘low-fat’, ‘low calorie’ options are hiding some ultra processed health horrors. The series comes at a critical time when families across Britain struggle with various health concerns linked to poor diet choices.

How the Show Works

Each week features one UK family suffering from various health concerns including obesity, headaches, high blood pressure, high cholesterol, hair loss, acne, stress, fatigue, and joint problems. GP Dr Kandi Ejiofor works directly with UK families to remove the worst UPF offenders from their diet. The premiere featured Vicki and Rob from Scarborough, a couple whose dependence on instant noodles has gotten out of hand, with Professor Tim Spector and Dr Kandi Ejiofor coming to their rescue.

Practical Solutions for Everyday Eating

Professor Spector offers nutritious alternatives and takes viewers back to basics, showing what to shop, cook and eat in a bid to transform the nation’s health. The team breaks down the creation of products like strawberry milkshakes, and the process is less than appetising. The hosts show families why they should ditch their snacks and boxed wine and turn to fermented foods instead, and demonstrate how to use natural ingredients to make healthier cookies.

What Viewers Can Expect

Part investigation, part intervention, What Not to Eat continues Channel 4’s tradition of making complex health science accessible, empowering families to make informed choices. By exposing hidden ingredients in everyday foods and providing practical alternatives, the series offers hope for those seeking to improve their wellbeing without breaking the bank or sacrificing convenience entirely.
