Exactly in 1998, FDA mandatorily legislated that the entire U.S population would be required to ingest folic acid. Then every man, woman and child in the U.S. (except celiac patients and Paleo Dieters) were forced to ingest folic acid whether they wanted to or not. They mandated that all enriched wheat flour was to be fortified with folic acid. Because most commercial wheat products (breakfast cereals, bread, cookies, cakes, crackers, doughnuts, pizza crust, hamburger and hotdog buns, wheat tortillas etc.) are made with enriched wheat flour, essentially the entire U.S. population began to consume folic acid in 1998.

Well, is it really safe to take folic acid? In the past several decades an accumulating body of scientific evidence now makes it absolutely clear that the FDA’s mandatory folic acid fortification program represents one of the worst blunders in the history of U.S. public health. An alarming number of human clinical trials, animal experiments and epidemiological studies show that excess folate via folic acid fortification has resulted in population wide increases in the risk for breast, prostate and colorectal cancers.
