A juice fast is a popular way to detoxify. Only water (in some cases unsweetened tea) and the juice from raw fruits and vegetables are allowed for a period generally lasting three days. The fruits and veggies should be organic, and as fresh as possible to ensure the highest possible vitamin content.
Grapefruit and pomegranate juice should not be used during a juice fast. In some cases, these juices can have negative effects with certain prescription drugs.
Between 32 and 64 ounces of juice are consumed each day of the fast, along with at least six glasses of room temperature water. You can use a variety of juices for your blend: beet, cranberry, celery, carrot, cabbage, kale, apple, pineapple, spinach and any kind of dark leafy greens. You will want to use a blend of both fruit and vegetables to ensure you are getting the full spectrum of vitamins to stay healthy. After blending a day's supply of juice, you will want to refrigerate the remainder.
