Most processed food contains sugar but that hasn't always been the case, and its history is steeped in slavery

Nearly every packet of food sitting on the supermarket shelves or in your home pantry contains processed sugar. "Before the industrialisation took place, it was a very long and arduous process because you needed to put stuff into the boiling sugar syrup to make it crystallise," Bosma says. "So at the time that Europe learned to love sugar … Europe began to look for other venues to grow cane," Bosma says. "In the 1860s, Queensland emerged as a sugar belt with labour from the Pacific Islands … and the conditions of these workers were horrific," Bosma says. "It's exhaustive to the environment if you grow sugar at a very large scale," Bosma says.
