Colon cleansing may be all the rage, but this is one fad you should forget, says a warning in The Journal of Family Practice. Just because health-conscious celebrities swear by it does not mean it is healthy or even safe. Proponents claim that the practice removes harmful toxins from the body, boosts the immune system and promotes weight loss. In truth, these fancy flushes are really nothing more than high-powered enemas that can use up to 60 liters of fluid to irrigate the intestines. There’s no evidence that any toxins are ever removed or that it’s even necessary. After all, your bowels eliminate waste material and bacteria naturally. There is, however, plenty of evidence that the procedure, whether done at home with supplements or at a spa, carries several risks, including vomiting, renal failure, infections, chemical poisoning and even death. Skip the cleanse and let your body do its job naturally. You can help keep your system pristine by eliminating processed and junk food and choosing mostly healthy, plant-based foods instead.
