Misconceptions About Juice Cleanses Everyone Needs To Know

They don't do what they promise.

Evolution has provided humans with plenty of ways to deal with the food we eat and the toxic byproducts our bodies naturally make, but that hasn't stopped many people from doing a juice cleanse.

On the surface, a juice cleanse seems like a really good way to kick off that New Year's diet many people plan on doing. For a few days, the body only gets nutrients from fruits and vegetables, allowing the body to rid itself of undesirable toxins and byproducts picked up from food and the environment. 

The only downside, however, is that's not exactly how the body actually works. 

In addition to having potentially dangerous side effects, going on a juice cleanse is really expensive. It can cost well over $150 for a three-day supply of juice from retailers. Even if someone chooses to make their own, a juicer strong enough to get the job done and the sheer volume of produce required makes it a really poor choice for many people. Coupled with the fact that the cleanse isn't really doing anything, the cost just isn't worth it.

SciShow host Hank Green breaks down some of the most common claims put forward by those selling juice cleanses by explaining basic human physiology. It's a must-see for anyone thinking of going on one of these diets:

While it's a great thought to want to take care of your body and give it what it needs, try making healthier decisions in general instead of shocking the body (and your wallet!) with an expensive cleanse that isn't remotely doing what it claims to do.
