How and what we eat has radically changed over the past few decades with the all-consuming rise of the supermarket. But what price are we paying for the homogenized, cheap and convenient food that supermarkets specialize in? In a two-part program, journalist Jane Moore investigates how supermarkets have affected the food on our plates and reveals the tell-tale signs that the food we buy may not have been grown in the way we think. Using a combination of undercover filming and scientific analysis, Supermarket Secrets investigates whether the food on supermarket shelves is really as good as it looks, whether prices are as good as they seem and what happens behind the scenes in the production of supermarket food. The film reveals problems and issues about the food and its production. Part two meets the organic potato farmer who feeds much of his crop to his cows because, he says, the supermarkets deem his produce to be insufficiently cosmetically pleasing. The film also hears from a toxicologist about the levels of pesticide residues in supermarket fresh produce; reveals how dairy cattle are now factory farmed and why packaged fruit and vegetables from your local supermarket may be more expensive that you think â€“ and not as good for you.
