Channel 4 introduces a new four-part series fronted by Professor Tim Spector, and our health expert/ GP – Dr Kandi Ejiofor. In “What Not to Eat’ we will discover how some of the most common health concerns affecting families across the UK can be helped by making simple changes to our eating habits by consuming fewer UPFs (Ultra Processed Foods.)  Each week will feature one UK family suffering from various health concerns including obesity, headaches, high blood pressure, high cholesterol, hair loss, acne, stress, fatigue, and joint problems.  The family will undergo testing and tracking from our health expert Dr Kandi, who will give them insight into their consumption of UPFs and prescribe them alternatives to get their health back on track. Meanwhile, Tim Spector will be providing viewers with the science behind UPFs; to help us understand why we want to eat them, why they can be damaging to our health whilst offering nutritious alternatives.
