Favoring Fiber - How Foods Fight Cancer

As you recall from the previous chapter, dietary changes can help
reduce the amount of estrogen and testosterone in the bloodstream.
Fiber is a key part of this. Fiber has other important benefits, too, as
we’ll see in this chapter.

“Fiber” is another word for plant roughage—the part of beans, grains,
vegetables, and fruits that resists digestion. Fiber helps to keep us regular by
moving the intestinal contents along. But it has other equally important roles.
It helps us rid ourselves of all manner of chemicals—including hormones—
that our bodies are anxious to eliminate.

This “waste disposal” system starts in your liver, which continuously
filters your blood. As blood passes through the liver’s network of tiny capillaries,
liver cells remove toxins, cholesterol, medications, waste hormones,
and whatever else your body figures it is better off without. These undesirables
are then sent from the liver into a small tube called the bile duct,
which leads to your intestinal tract. There, fiber soaks up these chemicals
and carries them out with the wastes.
