A temporal association between folic acid fortification and an increase in colorectal cancer rates may be illuminating important biological principles: a hypothesis. The possible mechanisms are unclear but might be related to folates role in methylation reactions in the brain, neurotransmitter synthesis, and homocysteine metabolism [117,118]. Honein MA, Paulozzi LJ, Mathews TJ, Erickson JD, Wong LY. Although most people consume adequate amounts of folate, certain groups, including women of childbearing age and non-Hispanic black women, are at risk of insufficient folate intakes.
