Body detoxification. Products that are based on the idea that your body is toxic. But here's a reality check. It's not. And buying any of these related products is an attempt to fix an issue that doesn't exist, according to Brian Dunning of the myth busting show inFact:
Our bodies have kidneys and livers that remove toxins and other waste from our systems, but in the past few years, clever marketers have said "Forget all that, you need our magic pills and potions to detoxify your body." It should be very telling that they never happen to mention what these supposed "toxins" are, or what your doctor should look for in a blood test to see whether you have them. They simply assert that we're all full of toxins, and that buying their miracle product is the key to health.
