If the colon is not working properly, even if it is just slightly not working, it WILL always have an effect in the health of the total body. It may take years for discernible symptoms to appear, but sooner or later they are going to manifest.
An easy self test on colon health is a simple transit time test. Simply eat 3-5 tbsp of cooked whole corn, without chewing it. Swallow it whole. Then check to see how long it takes before you see it eliminated in the toilet as it will still be undigested.
It should pass in 18-24 hours. If it takes much longer than that, you have a sluggish bowl.
After every meal, you should have a bowel movement.
Drinking 5 glasses of water daily decreases the risk of colon cancer by 45%.
