You know what, this forum has in the meantime corrupted my mind to such a despicable degree that I opened this thread fully convinced that "juice cleanse" referred to Gwyn's other habit of steam-cleansing certain juice-producing body parts of hers. You know Dave's use of colorful language, "doughnut bumpers" and "bagel babes" and such. I was - as is part of my generally inquisitive nature - immediately intrigued. And now it's all about fruit, Dave you sure know how to disappoint, thanks a bunch. Mind you, the first sentence of that article was still promising, namely "Put down the straw.", it had me thinking "Wow, don't these Yanks come up with the most interesting practices?!". Not for the ticklish though.
But that non-fruit cleansing can't be healthy either, plus it must be an acquired taste in more ways than one. Don't mess with nature.
And too much liquid fruit gives you diarrhea anyway - but for some reason women seem to mistake that as a sign of good health. Plus demineralizes your teeth, my dentist always says.
