麵粉中添加葉酸可減少出生缺陷

In the United Kingdom, a significant health initiative has been announced regarding the addition of folic acid to non-wholemeal wheat flour. This decision is aimed at reducing the occurrence of birth defects, particularly neural tube defects such as spina bifida, which can lead to serious health issues for newborns. The government estimates that this measure could prevent approximately 200 cases of these defects each year, thereby improving the overall health of pregnant women and their babies. Manufacturers have been given a deadline until the end of 2026 to comply with this new regulation. It is important to note that expectant mothers and women who are planning to conceive should continue to take folic acid supplements, which are the synthetic form of the naturally occurring vitamin folate. Medical professionals emphasize the importance of folic acid during the early stages of pregnancy, as it plays a crucial role in the proper development of the baby's brain, skull, and spinal cord. Many experts in the field of maternal and child health have expressed their support for the government's decision, as they have advocated for such measures for several years. The announcement comes in light of health improvements observed in other countries, such as Australia and Canada, where the fortification of flour with folic acid is already a common practice. However, some critics argue that the initiative does not go far enough, suggesting that more food products should be included in the fortification process. Professor Neena Modi, a leading expert in neonatal medicine at Imperial College London, raised concerns about the potential disadvantages this policy may create for certain groups. She pointed out that women who are sensitive to gluten, those who prefer rice over bread, and individuals who consume wholemeal flour may not benefit from this change. This could exacerbate existing health inequalities in the UK. Folic acid, also known as vitamin B9, is naturally found in various foods, including beans and green vegetables. Most individuals receive adequate amounts of folic acid through a balanced diet. The National Health Service (NHS) recommends that women trying to conceive take folic acid supplements for about three months prior to pregnancy and continue for at least 12 weeks after conception. This recommendation will remain unchanged. It is estimated that nearly half of all pregnancies in the UK are unplanned, making the fortification of flour a valuable strategy to increase folic acid intake across the population. This, in turn, will help protect unborn babies and promote healthier outcomes. The government's independent advisory body has thoroughly reviewed the evidence and concluded that fortifying flour with folic acid is the appropriate course of action for the benefit of society as a whole. However, it is worth noting that small-scale millers, those producing less than 500 metric tonnes of flour annually, will be exempt from this requirement. Flour is already fortified with other essential nutrients, including calcium, niacin, thiamine, and iron, as part of ongoing efforts to improve public health.
