Did you know?

The word raisin comes from the Latin racemus meaning a cluster of grapes or berries. Raisins have been produced since ancient times — Egyptian hieroglyphics from 2000 BCE depict raisin production and storage. Ancient Greeks used raisins as currency and prizes in sporting events. The concentration of sugars through drying that makes raisins a calorie-dense human food is the same process that concentrates the toxic compounds making them even more dangerous than fresh grapes for dogs per gram consumed.
