摘录
The Iowa researchers knew that when people moved from less developed
to more developed countries, the rates of autoimmune diseases rose in
the immigrant population. For example, in populations moving in the
1970s and 1980s from India, a country with high incidences of worm
infection, to the United Kingdom, where such infections are rarer, the
incidence of Crohn’s disease increased rapidly.2 And in the 1930s and
1940s epidemiologists had found virtually no occurrence of bowel
disorders in children living in the rural southern states of the
United States. Because pig farming was done on a regional basis and
many rural dwellers lived in close proximity to their livestock, worm
infections were much more common outside urban areas. As nationwide
programs were launched to tamp down worm infections among rural
populations and migration to urban areas increased, autoimmune
diseases became more prevalent.
Weinstock and his colleagues hypothesized that rather than the
presence of some environmental factor leading to the uptick in certain
autoimmune disease, perhaps the absence of something was to blame.
Maybe steering clear of worm infections was also robbing individuals
living in industrialized nations or developed urban centers of crucial
immune-system modulation that had arisen through millennia of
coevolution with these parasites, they reasoned. “This could be a
reason why, if people are infected naturally in a developing country,
they might not develop inflammatory bowel disease or other immune
diseases,” says Robert Summers. | N*****P

了。
当然，还有说法是在中国毒素多，空气质量差，我们习惯了就百毒不侵，美国太干净了
，所以慢慢的倒还免疫力下降了。有一定的道理。

发帖数: 1094 | 3 我认为是现在的诊段技术提高了，以前很多疑难杂症没办法确诊。
我们小时候也听说过有些孩子智利有问题又性格很古怪，放到现在大概都给盖上自闭症
的帽子吧。
要说起过敏，和吃的东西太丰富，环境太复杂也有关系。食物里乱七八糟的添加剂多，
环境污染也厉害，人体适应不了，各种过敏症也就多了。 | A******d

关于allergy,这个说法早几十年就有了。
但是还有很多新移民并没有过敏，怎么解释？

发帖数: 4054 | 5 你没有细读我的帖子。其实自闭和过敏是一个光谱的两个极端。
自闭是缺乏正常的免疫刺激和反应
过敏是机体对正常免疫刺激的过度反应。
都是人体对新环境的挑战无法适应的表现。
当然定义也有关系。比如癌症在过去可能就算正常死亡了；比如疯牛病都被归入老年痴
呆症了。等等； | s*y
