The UK says folic-acid flour fortification may prevent about 200 neural tube defect cases a year. But this is not risk-free arithmetic: the cancer question was serious enough for SACN to produce a formal report on folic acid and colorectal cancer risk, the World Cancer Research Fund notes that earlier UK concerns included possible increased colon-cancer risk, and a BMJ report noted evidence that doses above 1mg a day may increase the risk of multiple or advanced adenomas. The Government is therefore not choosing between 200 babies and no downside. It is choosing to medicate flour eaten by tens of millions while accepting unresolved concerns around cancer, B12 masking, and mass exposure without individual consent.
