For the first time, dark chocolate bars are outselling their milk siblings in Woolworths. "Two years ago the hot thing in chocolate was white. Now dark is the flavour of the month," according to Trevor Bish-Jones, chief executive of the pick'n'mix retailer that dominates the Easter-egg market.

"Consumers are doing the same thing in chocolate as in the rest of the food market. They are trading up and being more discerning about what they buy," he adds.

A compound in unrefined cocoa has health benefits that may rival those of penicillin and anaesthesia, they say.

Norman Hollenberg, professor of medicine at Harvard Medical School, has spent years studying the Kuna people in Panama. He found that four of the most common killers - stroke, heart disease, cancer and diabetes - affected fewer than one in 10 of the Kuna.

Unrefined natural cocoa contains high levels of epicatechin, which Professor Hollenberg said was so important it should be considered a vitamin.

He told Chemist and Industry magazine: "If these observations predict the future, then we can say without blushing they are among the most important observations in the history of medicine. We all agree that penicillin and anaesthesia are enormously important. But epicatechin could potentially get rid of four of the five most common diseases in the Western world. How important does that make epicatechin? I would say very important."
