How much is a cup of fruit or veggies because you cannot really measure them. For example, how many cups is an apple?
The best approach is to estimate as best you can. For instance, in general one cup looks like the size of a baseball. Generally, a small to medium piece of fruit will be equal to a cup. To help estimate, view pictures of one cup portions here. Our kids section also has some downloadable pictures to give you an idea of what a cup looks like. Click here to see them.
