Secrets of Your Supermarket Shop S02E01 - Dairy

Sian Williams and Stefan Gates present the documentary lifting the lid on the growth, production and sale of supermarket food. They begin with an investigation into dairy products, visiting a dairy farm to find out how they supply the huge demand for milk - and also finding out why plant-based milk alternatives can cost four times as much. Plus, a report on the sugar content of some of the most popular yoghurts on the market.
