i found this online because i was paranoid that we needed that mucus in our intestines for something. and we do! but too much can cause problems. and with all this crappy food that is out there you know taht everyone has some sort of build up.

anyway..what i found:

"Mucoid plaque causes constipation. If you have a layer of hardened mucoid waste lining your intestines, then it stands to reason that normal peristalsis is hampered. But what causes the mucoid plaque in the first place? This is your body’s natural protection against foods that may have created a strong acidic reaction or an allergic reaction and this thick, sticky mucous protects the intestines from damage. The problem is that if it happens on occasion, it will not stay, but if the offending food continues over time, the plaque just builds up. Another reason that the mucoid plaque can start forming is nature’s way of protecting you from something that you may have swallowed that is now stuck in your intestinal tract. For example, if you swallowed a coin like a penny or a dime when you were a child, your body would encapsulate this foreign object to “protect” you from it. Unfortunately, this starts a life-long chain of events that can lead to so many problems. The good news is that on a good cleansing program, these objects will be pulled out, along with the mucoid waste! "
