Dietary Fiber Prevents You from Cancer, Part III

Can Fiber Cause Trouble?

( continuation of the previous article )

Scientists believe that we may be able to adapt to high-fiber diets. But this is not known for sure. It is speculation based on a handful of studies.

The effect of fiber on minerals varies among the different types. Here is what scientists think based on current knowledge:

  • Iron nutrition probably won’t be affected by eating more fiber.
  • Fiber probably will decrease absorption of zinc and copper.
  • If zinc and copper intake is good, the decrease in absorption probably will not create any problems.

Whole grains contain more zinc and copper than refined grains, so this may offset any loss of these minerals resulting from the fiber. But until we know this for a fact, I feel it’s best to take a moderate rather than extreme approach to the fiber content of your diet.

Fiber is not the only substances in whole grain foods that can bind to minerals. Whole grains also contain phytic acid, which can also tie up minerals. Nutritionists also refer to phytic acid as phytate.
