Food high in folic acid is important as humans need folate for a number of bodily functions. Folic acid allows for the synthesis of DNA, repairing of DNA and a series of other processes. It aids in rapid cell division and growth, as well as the decrease in risk of cancer.
Folic acid is a key part of any healthy diet. I think you should say: People who avoid having food high in folic acid often end up suffering from folic deficiency, something that may take up to four months to start -- because the body typically stores a certain amount of folate to begin with. Some of the problems that deficiencies of folic acid and not having food high in folic acid cause include neutral tube defects, diarrhea, macrocytic anemia with weakness or shortness of breath, pregnancy complications, mental confusion, forgetfulness or other cognitive declines, mental depression, sore or swollen tongue, peptic or mouth ulcers, headaches, heart palpitations, irritability, and behavioral disorders.
