Apples and citrus fruits are excellent for detoxifying diets because they contain large amounts of pectin, which binds with the toxins and carries them through the digestive tract without them being absorbed by the body. You should be sure to drink plenty of water during any kind of fast - at least 8 glasses a day. You can also drink fruit juices and non-caffinated herbal teas, but be sure to plenty drink pure water too. If you dislike the taste, try some bottled brands, and add a squirt of lemon juice. During your detox, take 1000 mg Vitmain C each day.
