SEATTLE - Doctors at Seattle's Swedish Medical Center are worried a new study linking autism with high intake of folate or folic acid could do more harm than good, KCPQ reports.
Pregnant women are urged to eat foods high in folate.
Leafy greens, citrus fruits and beans are high in folate and the vitamin form of that is called folic acid.
Doctors have been recommending folic acid supplements and prenatal vitamins with folic acid for years in case women are not getting enough folate in their diet.
But now researchers from Johns Hopkins University are linking autism with a high intake of folate or folic acid.
