Professor Brian Cox and our expert panel dive into the complex world of diet, nutrition and food choices. 

With new probiotic and high-protein products appearing on supermarket shelves every day and conflicting nutritional advice coming from every direction, it’s difficult to cut through the noise when it comes to what we eat. 

Our panel uses expertise from their roles as nutritionists, geneticists, gastroenterologists and policymakers to answer audience questions about food advertising, wellness advice, and whether it’s really possible – or worthwhile – to avoid food ‘additives’.
