`Food Unwrapped' sets out to answer the question of what really goes into the food that we eat, as its team of hosts travel across the world to discover how popular food is mass-produced. The programme tries to get answers from supermarkets and food producers, but when those attempts fail, the team do whatever is necessary to find out. Heading inside factories, the inquisitive foodies meet scientists, factory owners, growers and producers to reveal information about food that is largely unknown.
