Which vitamin is commonly added to cereals and breads alongside thiamine, riboflavin, or niacin to prevent neural tube defects?

• A. Thiamine
• B. Riboflavin
• C. Niacin
• D. Folate

Answer: (D)

Folate is added to cereals and breads to prevent neural tube defects because this vitamin is essential for DNA synthesis and cell division, which are critical as the fetus’s brain and spinal cord are forming very early in pregnancy. Adequate folate around conception and in early gestation reduces the risk of neural tube defects such as spina bifida. That’s why folic acid (the synthetic form used in fortification) was incorporated into enriched grains in many countries, alongside the vitamins previously added during milling—thiamine, riboflavin, and niacin—to restore nutrients lost in processing and support overall metabolism. The link here is clear: ensuring sufficient folate specifically helps prevent neural tube defects, whereas the other vitamins serve other metabolic roles.
