A serving of fresh fruit or vegetables depends on the size of the food. Inthe case of small-sized fruit like plums or mandarin oranges, one serving is two pieces of fruit. A piece of medium-sized fruit like apple, an orange, or a pear also counts as one serving. With larger fruit like melon and pineapple, one serving is a one-half cup or about 3 ounces. We use the same method for calculating servings with vegetables. In the case of salad vegetables, a medium-sized tomato or 3.5-inch piece of cucumber count as one serving each. For smaller, cooked vegetables like beans and carrots, one serving is three large sponfuls of vegetables.
