Its these adsorptive properties of activated charcoal that led to its use as a detox ingredient. In 2014, Gwyneth Paltrow’s newsletter Goop (infamous for its pseudoscience claims) recommended charcoal-infused lemonade as one of the year’s top juice cleanses, which brought the substance to the wellness limelight. (You can still find plenty of activated-charcoal claims on her website.) But here’s the thing about detoxing: It’s a total hoax. Your body is already great at removing environmental toxins and ones mixed in with the food you eat or drink as part of its regular waste processing. Evidence that this system is working well appears every time you go to the bathroom. The best thing you can do to keep it that way is to eat lots of healthy food, get exercise, wear sunscreen, and get enough sleep—basically, the usual things any health professional would recommend.
