CDC grand rounds: Additional opportunities to prevent neural tube defects with folic acid fortification. Intakes of folic acid that exceed the bodys ability to reduce it to THF lead to unmetabolized folic acid in the body, which has been linked to reduced numbers and activity of natural killer cells, suggesting that it could affect the immune system [5,155].

In addition, folic acid in combination with a multivitamin supplement helps minimize the risk of congenital heart defects, possibly because cardiac tissue development depends on cells that require large amounts of folate [1,2,132]. However, the hallmark feature of blind loop syndrome is megaloblastic anemia, which results from inhibition of DNA synthesis during red blood cell production, and is caused by the disruption of vitamin B12 absorption. This section focuses on seven diseases and disorders in which folate might play a role: autism spectrum disorder; cancer; cardiovascular disease and stroke; dementia, cognitive function, and Alzheimers disease; depression; NTDs; and preterm birth, congenital heart defects, and other congenital anomalies.
