A survey by vending machine specialist VendEase examined the snacking habits of the 46,000 construction workers who helped build the Olympic Park and Village.

Analysis of the firm’s 25 machines on the site shows the workers were getting through 7,000 Boost bars a month.

The Boost bars were closely followed by Twirl, Whisper and Snack Shortcake in the favourites list.

Dave Berman, director of UK-based VendEase said: “The Olympic Park Big Build was a military operation and we’re proud to have played our part in keeping that army of builders marching on its stomach.”
