莫顿盐业碘缺乏病甲状腺肿美国 |

偶然读到美国星期六晚邮报2019年5月13日旧闻，以《盐是如何提高我们的智商》（How Salt Made Our IQs Go Up）为题，介绍了莫顿盐业公司生产的碘盐对控制美国甲状腺肿的贡献。
该文后部分提及：“莫顿在1924年推出一项更重要的创新（注：食盐加碘）。科学家们发现，碘可以治疗常见的甲状腺疾病（即甲状腺肿，见后）。五大湖地区和西北太平洋地区的居民，因为生态环境中碘缺乏，很容易患甲状腺肿大或或（地方性）甲状腺肿。碘缺乏还影响大脑，导致学习或记忆困难。””读者可能会认为1927年的广告（见图片）夸大了加碘盐的好处。但在加碘后，甲状腺肿的发病率显著下降，在已经引入加碘盐的地区，平均智商上升了15个点，而全国（美国）则上升了3.5个点。”
作者感叹，莫顿在美国消除碘缺乏病（包括地方性甲状腺肿）方面发挥了巨大的作用。至今，莫顿在美国仍生产和出售加碘盐。（作者译：Morton's business development in China can be traced back to the time before the liberation. Although the price is not low, Morton's salt is bought by at least 500 thousand consumers according to comments on JingDong. However, most of them are non-iodized salt, and its iodized salt accounts for only a small part (20 thousand).）
莫顿在中国开拓业务可以追述到解放前。现在，尽管其价格不低，但在京东上，莫顿销量超50万（按评论数）。然而，这份成绩源自莫顿的非加碘盐，其加碘盐只占少部分（2万）。要知道中国大部分地区是缺碘地区。面对此情此景，作者扼腕叹息！不知莫顿盐业公司如何看待这份业绩。（作者译：It can be seen that Morton has played an
important role in eliminating iodine deficiency disorders (IDD,
including endemic goiter) in USA. To date, Morton still produces
and sells iodized salt in USA.

How Salt Made Our IQs Go Up
Morton Salt has long been known for its famous logo featuring the iconic “umbrella girl” — dressed all in yellow and walking in the rain as salt pours freely from a container of Morton’s — over the phrase “When It Rains, It Pours.”
She first appeared in 1914, in the days when table salt tended to clump up when exposed to humidity. The problem was solved by the Morton Salt Company when it added magnesium carbonate, an absorbing agent, to its product. The new salt would flow freely in even the most humid weather.
But Morton introduced a more important innovation in 1924. Scientists had discovered that common thyroid disorders could be remedied with iodine. People in the Great Lakes region and the Pacific Northwest, which had too little iodine in the ecosystem, were prone to developing enlarged thyroids, or goiters. Iodine shortage also affected the brain, leading to difficulty in learning or remembering.
Readers might have thought the 1927 ad was overstating the benefits of iodized salt. But the incidence of goiters dropped significantly after iodization, and the average IQ rose 15 points in areas where iodized salt had been introduced, and 3.5 points nationally.
