I discovered I have Irritable Bowel Syndrome and Diverticulosis. Google them up.
The Diverticulosis is caused by not eating enough fiber. The disease did not exist until the late 1800s when they started grinding grains so fine that they reduced the fiber in them to a powder.
Our digestive system is designed to use fiber. Not enough fiber and it goes out of whack. The amount of fiber is stated on every food package.
The real cause of IBS is not known but eating fiber helps mine almost to the point of eliminating it.
Eat plenty of vegies, preferably raw, fruit, whole grain cereal and breads and you will have no problems with the poopery.
