I put it in quotes because I have no idea if there is an effective way to do it. I have read articles in Mens Health about combinations of foods (mostly exotic fruits). I have seen/heard commercials for everything from teas to powders you put in foods to pills that help your liver do it. I have read that exercise and sweating does it. They even sell pads to put on the bottoms of your feet while you sleep that supposedly "absorb toxins" from your system and turn black overnight. My wife gets three days of juices in every few months and that's all she consumes for those days. Supposedly that's one of the reasons she does it. We have experts here for everything else, so why not this? If it is possible, how does one do it? Have you successfully done it, and if so how do you know? Is it really possible? Just pop science? Snake oil?
