High-fiber diet may interfere with ovulation

High-fiber diets are associated with lots of health benefits. But, a new study suggests, eating the recommended amount of fiber about 22 grams a day may interfere with ovulation. The research in the American Journal of Clinical Nutrition finds women on fiber rich diets have lower estrogen levels and ovulate less.

High-fiber diets are thought to decrease activity in certain intestinal enzymes, leading to less estrogen absorption . Still, researchers say the finding does not mean that eating a fiber-rich diet is a bad thing. But they question where women who are trying to get pregnant should lower their fiber intake.

More studies are needed before any recommendations can be made.
