Dietary reference intakes for folate: the debut of dietary folate equivalents.
The differences in absorbability have led to the concept of dietary folate equivalents (DFE), where 1 DFE = 1 [micro]g food folate = 0.
Then, in 1998, dietary folate equivalents were established--because of differences in bioavailability, or absorption--of at least 400 mcg per day for adults.
