Hi - You are very welcome. "The Detox Book" by Bruce Fife, ND, has good information on many aspects of detox including healthy diet, oxygen therapy, colon cleansing, kidney cleansing, herbal detox, and (my personal favorite) healing crises. It includes a chapter on fasting and one on juicing. The information in my previous post is from this book.
He says that apples, grapes, Watermelon and carrots can be used for the monofood diet. He also says "Try a monofood diet a couple of times. Then as your body becomes healthier and more accustomed to going without the foods you normally eat, try juice fasting. On prolonged fasts some people find that can handle a juice fast easier if they start it with a three-day monofood diet."
