Trying to conceive? A new study shows that if that's the case. You may want to cut back on the soy. The study, published in the medical journal Reproductive Toxicology
, revealed that dietary exposure to genistein, a compound found in soy foods like tofu, can make it significantly more difficult to get pregnant and stay that way.
In the study, researchers examined the impact of genistein exposure on the eggs from female adult mice and found that the compound keeps the eggs from becoming mature and reduces their potential to become fertilized. For eggs that do become fertilized, genistein hampers the growth of the newly formed embryo.
Scientists have yet to fully interpret the results of this study ... after all soy is currently thought to be a healthful food that provides excellent protection for the heart. And it remains to be seen whether or not this compound would react the same way in humans as it does in mice. But it certainly provides "food for thought," for couples who are having trouble conceiving.
