In a rat model, following exposure to rat folate receptor alpha antibodies (FRαAb) during gestation, FRαAb accumulates in the placenta and the fetus and blocks folate transport to the fetal brain and produces behavioral deficits in the offspring. This hypothesis is supported by a 2011 prospective study that found an inverse association between folate intake and risk of colorectal cancer only during early pre-adenoma stages [83]. Although the mechanism has not been fully established, clinical trial evidence shows that adequate periconceptional folic acid consumption by women prevents a substantial proportion of NTDs [3,81,132,133,136,137].

A value of 3.0 ng/ml or less indicates a folate deficiency. Another risk involves the use of folic acid to treat a folate deficiency, but because a folate deficiency closely resembles a vitamin B-12 deficiency, if the B- 12 deficiency goes undiagnosed, the treatment can lead to irreversible brain damage.
