Conventionally grown apples contain the highest traces of pesticides in supermarkets than any other crop. Even after apples were washed, 48 types of pesticides were discovered by the EWG. Farmers use a wide range of chemicals on apple crops because they’re highly susceptible to regional insect infestation and blights. Apple skins absorb these pesticides to fight these environmental problems, but the chemicals remain in the fruit long after harvest. In addition to organic apples not being laden with as many pesticides, their skins have been shown to contain 15 percent more antioxidants than non-organic apples.
