Watercress is another in a long line of so-called "Superfoods", but this time there's a rigorous study to support its claims. Elinor Goodman visits fourth generation watercress farmer, Tim Jesty and his father Bill on what was once their farm in Dorset to discover how this vegetable is produced. She also discusses the future for the crop with Tom Avery, who now manages their farm on behalf of a co-operative company.
