The United States Food and Drug Administration (FDA) required all enriched cereal grains to be fortified with folic acid in 1998. In April 2016, the FDA published regulations allowing voluntary fortification of corn masa flour with folic acid to address the high prevalence of folic acid-preventable spina bifida and anencephaly among Hispanics. Our objective was to survey folic acid-fortified corn masa and corn tortilla products in the country using a national social media campaign.
In January 2019, we conducted a social media campaign (#FindFolicAcid) engaging citizens nationwide to survey local stores for folic acid in corn masa flour and corn tortilla products. Photos of products and nutrition labels were shared with the researchers on various social media portals (e.g., Twitter, Facebook, and Instagram). The posts were summarized for a descriptive analysis.
People from 28 states shared photos of 132 products, including 43 unique corn masa flour or corn tortilla products. Of those, only three corn masa flour products included folic acid: (a) Maseca Instant White (4.4 lb bag); (b) Masa Brosa Instant; and (c) Masa Brosa Instant Blue. None of the corn tortilla products were fortified.
There is a failure of voluntary folic acid fortification of corn masa flour and products nationally. Until folic acid fortification of corn masa products is implemented fully in the country, Hispanic women of reproductive age should take a daily vitamin supplement which includes at least 400 mcg of folic acid to prevent spina bifida and anencephaly.
1998 年,美国食品和药物管理局(FDA)要求所有强化谷物必须添加叶酸。2016 年 4 月,FDA 发布了允许在玉米粉中添加叶酸进行自愿强化的规定,以解决西班牙裔人群中叶酸可预防的脊柱裂和无脑畸形的高发病率。我们的目的是利用全国性的社交媒体活动调查全国叶酸强化玉米粉和玉米饼产品。
2019 年 1 月,我们开展了一项社交媒体活动(#FindFolicAcid),动员全国公民调查当地商店玉米粉和玉米饼产品中的叶酸含量。产品的照片和营养标签被分享给研究人员在各种社交媒体平台上(如 Twitter、Facebook 和 Instagram)。对帖子进行了总结分析。
来自 28 个州的人们分享了 132 种产品的照片,其中包括 43 种独特的玉米粉或玉米饼产品。其中,只有三种玉米粉产品含有叶酸:(a)Maseca Instant White(4.4 磅袋);(b)Masa Brosa Instant;和(c)Masa Brosa Instant Blue。没有一种玉米饼产品是强化的。
全国范围内玉米粉和产品的叶酸自愿强化工作失败。在全国范围内全面实施玉米粉产品叶酸强化之前,处于生育年龄的西班牙裔妇女应每天服用包含至少 400mcg 叶酸的维生素补充剂,以预防脊柱裂和无脑畸形。
