Avoid alcohol if you suffer from impaired liver function, and only drink in moderation (no more than two glasses of wine or beer, no more than two ounces of hard liquor per day for men, half that for women). Alcohol overloads detoxification processes and can lead to liver damage and immune suppression.
Tips to cleanse with fruit and vegetable Juice
Most healthy people do not need to go on a strict water fast to aid in detoxification. Instead, a three-to-five-day fresh fruit and vegetable juice fast actually provides the greatest benefit. (Note: only fresh fruit or vegetable juice, prepared from a juicer, should be used to aid elimination, because fresh juice provides valuable enzymes to our system.)
Drinking fresh juice for cleansing reduces some of the side effects associated with a water fast, such as light-headedness, fatigue, and headaches. While on a fresh juice fast, individuals typically experience an increased sense of well-being, renewed energy, clearer thought, and a sense of purity.
Although a short juice fast can be started at any time, it's best to begin on a weekend or during a time when you can be sure to get adequate rest. The more rest, the better the results, as energy can be directed toward healing instead of toward other body functions.
Prepare for a fast on the day before solid food is stopped by making the last meal one of only fresh fruits and vegetables (some authorities recommend a full day of raw food to start a fast, even a juice fast).
Consume fresh juice for the next three to five days, ideally four 8 to 12-ounce glasses throughout the day. Virtually any fresh juice provides support for detoxification; however, some of the better juices to consume during a fast include pineapple-ginger; cranberry-apple; spinach-celery-kale-apple; kale-broccoli-cabbage-carrots-apple; and parsley-carrot-spinach-celery-tomato.
The ability to detoxify is one of the critical factors for health. It's amazing just how well the body handles the constant onslaught of modern living. Periodic juice fasting, as well as a long-term approach to detoxification, can be used to support the body's detoxification mechanisms.
