"But there are some things caused by problems with your bowel movements that I bet you never connected. Like varicose veins! Like prolapsed uterus! Like hiatal hernia! How in the world would these be connected to the bowels? The way they are connected to the bowels is becuase of the severe straining that people go through to pass their constipated, rock hard, tiny American stool.

When you eat the Western diet, it has very little fiber in it. As a result, you get this tiny little fecal mass. It takes great effort to pass it out of the body. You know the grunting, the groaning, the straining that takes place when people sit on the throne.

[varicose veins] What happens when you apply all that pressure is you push blood into your face; your face turns red. You push blood into the hemorrhoidal vein, so they get streteched out and you get hemorrhoids. We also push blood into our legs — the veins in your legs — these veins get dilated. There are little valves in those veins that occur as we move from our feet up to our heart. These little valves prevent the blood from flowing back towards the feet. So as you walk, what happens is that blood gets forced up through the valves, the valves close and blood can't get back down. That's how it's supposed to work … the column of blood. But when you grunt, groan and strain for years to pass the constipated American stool, you put so much pressure on those veins that you ruin the competency of those valves. As a result, the veins dilate, then we have the 'blue worms' on the legs — we call those varicose veins.

[prolapsed uterus] Well that same straining puts great pressure on the ligaments that hold the uterus of a woman. And as a result of all that straining from constipation pushes her uterus over the years down to her vagina. And it sometimes hangs out; that's how we get a prolapsed uterus.

[hiatal hernia] When you grunt, groan and strain, you push the stomach into the diaphragm. Diaphragm is the muscle that separates the abdomen from the chest. And there is a hole through which the esophagus passes. Now when you grunt, groan and strain, you push the stomach up through that hole and you dilate it. A dilated muscle is called a hernia. That's how you get a hiatal hernia.

Now these are permanent structural changes. They can't be fixed by changing your diet. They can be fixed in part by a surgeon — that's a last resort. If you just change what you eat, then you can slow or stop the progression of these particular structural problems."
