I found this for you, Mariska. Hope it helps.
Dried fruit such as raisins, banana chips, dried pineapple, prunes or dried apricots offer you one serving per 1/4 cup. A single serving of canned, frozen, chopped fruit or fruit juice equates to 1/2 cup. A medium-sized piece of whole fruit such as a banana, peach or apple counts as one serving.
