Juices – even juices that are part of commercially sold cleanses – have a lot of sugar and also lack the fiber, which scrubs the intestines and binds to toxins, promoting their elimination. (Don't believe us about the sugar? Consider: BluePrint Cleanse's pineapple apple mint has 45 grams of sugar. A regular Coke has 39 grams.) Juices also leave you hungry and grumpy. "You're not nourishing yourself with juice, and it doesn't kill bad bacteria," says Lipman. If you must, stick to a single serving of one that is pure greens, no fruit added. Check labels; you want less than 4 grams (1 teaspoon) of sugar.
