The whole theory behind the use of colon cleansing and detox diets rests on the idea that waste builds up in the colon. This happens when you don't get enough fiber in your diet to get rid of the waste and you eat too much junk food with a lot of fat and sugar. Additives in food also contribute to the problem. Without enough fiber to remove the waste, it becomes trapped in the colon and becomes toxic. Eventually, the toxins leak out into your body and get into your bloodstream where they travel to the heart, liver and kidneys. Even though your kidneys and liver are meant to filter impurities from your bloodstream, there are too many for them to do the job efficiently. This is why many people believe it is not only necessary to clean your own colon, but to detoxify the bloodstream and organs, as well.

There are products you can buy individually or in a kit that can be used for a cleansing or for a detoxification, or both. Many people have claimed to have passed all types of "strange creatures" in their waste while using cleansing products, including long, twisted ropes that they think are parasites. In reality, this is often produced by the ingredients you are taking rather than the waste you are producing. Although some of these products contain anti-parasitics to rid your body of any parasites that may be living in your intestines. These can be microscopic in size or several feet in length. Human parasites can cause serious illness such as anemia or even death. However, you may never know if you have passed parasites during a cleansing and the long, twisty things shouldn't be confused with tape worms, either.

No matter what type of colon cleansing and detox diets you have tried or are considering trying, they should be used in moderation for short period of times. Any diet that restricts your nutrition for long periods of time can only lead to complications.
