For every pound we spend on food shopping, 77p goes to the supermarkets, giving them a huge influence over what we eat. But can we trust the supermarkets to tell us the truth about what we are buying and how it was produced? Or do their profits come first? In an experiment to discover the hidden truths about our everyday foods, Horizon has built the first ever truly 'honest supermarket'. Drawing on the latest scientific research and leading experts from across the UK, the team have built a supermarket where the products are labelled with the real story of how they are produced and their effect on us and the environment. We invite the British public to come in and discover the truth about their favourite foods. And in our on-site lab, new scientific discoveries reveal the food facts the supermarkets aren't telling you. Presented by Dr Hannah Fry and dietician Priya Tew, The Honest Supermarket takes a cold hard look at what's really going on with the food we eat. From new research that reveals you're likely to be ingesting plastic particles along with your bottled water to the lab tests that uncover the disturbing truth about just how old your 'fresh' supermarket fish really is… You'll never look at the food on your supermarket shelves in the same way again.
