Mandatory vitamin B12 fortification of enriched grain products is long overdue in the United States and Canada. Fortification would help provide the 2.4 mug of synthetic vitamin B12 that the US Institute of Medicine recommends for all persons 50 years and older. The findings of Ray and colleagues in this issue suggest that B12 may also help to prevent neural tube defects. If recommendations for B12 fortification were followed, it is possible that cases of spina bifida and anencephaly would be prevented. Two hundred twenty thousand children each year acquire folic acid-preventable spina bifida because many governments, including all in Europe, have yet to implement mandatory folic acid fortification. Fortification with folic acid and vitamin B12 is safe and should be implemented in all countries.
在美国和加拿大,早就应该对强化谷物产品强制添加维生素B12了。添加维生素B12将有助于提供美国医学研究所建议的50岁及以上所有人所需的2.4微克合成维生素B12。Ray及其同事在本期中的研究结果表明,维生素B12可能还有助于预防神经管缺陷。如果遵循维生素B12强化建议,就有可能预防脊柱裂和无脑儿病例。每年有22万儿童患上可通过叶酸预防的脊柱裂,因为包括欧洲所有国家在内的许多政府尚未实施强制添加叶酸。添加叶酸和维生素B12是安全的,所有国家都应实施。
