Did you know that things such as food allergies, chronic fatigue syndrome, and arthritis could be caused by organisms living in your intestinal tract?
Here's a little of what the Dr. had to say:
What's Living in Your Digestive System
One of the most toxic environments to which people are exposed is within their own gastrointestinal tract. From the mouth to the anus, every inch is colonized by bacteria. The alimentary canal is basically an external surface internalized within the human body. It remains in contact with the external environment.
The gastrointestinal tract is a complex and dangerous frontier.
All the nutrients required for life must pass through, while the bad guys are kept out. Given the large area, there is much that can go wrong, leading to a huge range of ailments. In keeping with its immense surface area and intense exposure to foreign antigens, the intestinal tract is the largest organ of immune surveillance and response in the human body.
For anyone unfamiliar with cleansing, one of the primary purposes of doing so is to clean out the intestinal tract.
Prior to starting to cleanse, I suffered from constant yeast infections, and had several system wide infections (which believe me are nasty).
When I first learned about cleansing I was told that it would help with the yeast.
During my first serious cleanse, when I went in for my first colonic, the technician showed me on the monitor all the excess yeast flowing out of my intestinal tract (for those of you who don't know a colonic is essentially a giant enema that cleans out your entire intestinal tract).
Since then, yeast infections have become a rarity.
So, I can attest to the fact that a "dirty" intestinal tract can cause unexpected health issues in other areas of your body.
A good cleanse not only helps in your weight loss/maintenance efforts, but is also good for your health.
