Core the apples and cut them into slices. Cut the beet into quarters.
Juice the apples, beet, carrots, celery, and parsley together, alternating the different kinds of produce as you juice. Serve immediately or save in glass bottles for later consumption.
This recipe won't blend well as it's made for a juice extractor. If you'd like to blend, a general rule for converting a juice into a blended juice is to cut the recipe ingredients in half and add 1/2 - 1 cup water.
