Brian Cox and Robin Ince examine their own diets and the diet fads of the past to ask what we should actually be eating. They are joined by Dr Chris van Tulleken, Professor Janet Cade and comedian Harry Hill to discuss the nutritional merits, or lack thereof, of everything from sausages to strawberries, and discover whether our obsession with low fat, low sugar or low carb diets have any scientific basis. They discuss our increased dependence on ultra-processed foods and what this means for our health, and whether eating one calorie of a chocolate bar is really the same as eating one calorie of a stick of celery. New episodes are released on Saturdays. If you're in the UK, listen to the full series first on BBC Sounds: bbc.in/3K3JzyF Producer: Adrian Washbourne Executive Producer: Alexandra Feachem
