Sustain Our Earth

When and why did food became an addiction? And is fat consumption or sugar consumption the greater culprit? Jacques Peretti (pictured above) investigates.

"Genetically, human beings haven't changed, but our environment, our access to cheap food has," says Professor Jimmy Bell, obesity specialist at Imperial College, London.

"We're being bombarded every day by the food industry to consume more and more food."

One of the biggest changes in our modern diet stems back to the 1970s when US agriculture embarked on the mass-production of corn and of high-fructose corn syrup, commonly used as a sweetener in processed foods. . . .
