In primary school, I was taught that the intestines are just tubes that food goes through. I have spent a career in medicine witnessing just the opposite. Nothing could be further from the truth.
The intestines are made up of the small intestines and large intestines, both with their own functions. To understand how things work, it is best to start with the stomach. This is an organ that secretes acid, bile and enzymes into any incoming food product to make it into liquid mulch. This mulch then enters the long yet narrow small intestine. It is a living changing organ with a large absorptive surface, through which only molecules can enter selectively. It is capable of defending itself, living in harmony with various bacteria and rejecting non-essential molecules. Furthermore, it rejuvenates itself on a daily basis. Whatever is not absorbed enters the large intestine, which specialty is to extract water from the mulch and then shrink it into a small disposable refuse.
Technically, something in your intestine is not considered to be inside your body, until the intestine cells absorb molecules of the substance and deposit it into the blood. This system has been in development for hundreds of thousands of years, and is about as perfect as it gets.
It always boggles my mind when people think that they can improve on the mystic work of higher powers. For instance, the bowels are a strict one way system. There has never been a need to introduce fluids or substance from the anal end to improve function. There is no way that any substance or fluid artificially introduced through the anus, can even reach the small intestine where some people think pounds of toxin hide. It's just too far.
I know numerous gastroenterologists who perform screening tests with long flexible cameras to look for disease and remove pre-cancerous polyps. In all their combined years of looking, not one has claimed to have seen pounds of toxins hiding anywhere. You can do a virtual tour of these procedures on the internet, and quickly realize that all you see is the healthy pink tissue of the intestinal lumen. It would make no sense to have a constantly changing fine tuned system that has not accounted for this.
The best way to be kind to your intestines is to treat them to freshly grown wholesome plant food, with slight bits of fish and meat on the side. Eating well with lots of fiber will change how they function, produce healthy gas, burps, and anal exhausts. If you avoid dumping toxins down the hatch, there will be no reason to worry. Fasting for 24 to 48 hours with copious water is the best way to give them a break, if you feel you need this. If you are over 60 and healthy, treat them to a colonoscopy, a great way to do a minor tune up and stay healthy.
