Whether your dinner plans include tacos, spaghetti carbonara, crispy
fried rice, or just a bacon-lettuce-tomato on toast, you can bet that you
will be having folic acid tonight. Since January 1, 1998, the US Food and
Drug Administration (FDA) has required that all enriched cereal grains must
be fortified with 140 µg of folic acid per 100 g of grain.1
This regulation was introduced because folic acid, taken prior to conception,
can prevent many neural tube defects (NTDs) and because an alarming number
of women of childbearing age were not following the US Public Health Service
recommendation to take 400 µg/d of folic acid routinely.
