Folic acid is known for decreasing the number of birth defects. Now there's evidence it may also cut down on some childhood cancers. The US food supply has been fortified with folic acid since the late 90's. It's been shown to reduce the prevalence of neural tube defects by nearly a third.
Now researchers at the University of Minnesota have found evidence that it may have also reduced rates of some rare childhood cancers, which includes a form of kidney cancer and tumors of the central nervous system. More research is needed to show a cause and effect relationship between the supplement and those lowered cancer rates.
