怎么办啊？ 要去买东西吃了。哪些安全呢？

[老闹子]

现在我手上没有权威数据，没法与你争。等我查到过敏症发病率随年份变化数据再说。但我个人观察是那里华人没这里普遍。需要指出的是，欧洲是与美国同一年商业化转基因玉米的。

论坛上以前就有人问过这个问题，北美过敏普遍是否跟转基因食品有关？

当时我怀着好奇心去姑姑了一下资料，有世界卫生组织的统计，好像是说工业发达国家里的过敏现象在过去的五十年里一直在增加。看到这里，我基本认为不可能用转基因食品来解释北美历史上的过敏发展史了，因为大家都知道北美的转基因是什么时候才开始成为食物的。

刚才再查了一下，资料在这里，很简单的一句总结而已。我希望有更详细分年的资料或曲线，就更能说明问题。

这个问题目前医学界还没有结论。

我是真关心这个问题，不是为争论而争论，因为这个确实很严重，而且我们家就有一位季节过敏的。

Allergy Statistics and Facts

• Number of people in the U.S. who have either allergy or asthma symptoms: one in five.
• Percentage of the U.S. population that tests positive to one or more allergens: 55%.
• Rank of allergies among other leading chronic diseases in the U.S.: 5th.
• Number of weeks by which the ragweed pollen season has increased in the last 10 to 15 years, likely as a result of global warming: four.
• Number of people with chronic allergy-like symptoms -- runny nose, congestion and cough -- but who have nonallergic rhinitis instead: one out of three.

老二，我在欧洲生活多年
那时候没GM产品卖，我们在欧洲生活长时间后，春秋天流眼泪打喷嚏咳嗽都不奇怪

我的很多亲戚朋友，美国，欧洲，日本的都有，怎么会不知道那里情况？
我们家很多人，只有一个人吃玉米的过敏，春秋流眼泪，很难受的。但其他人都没事。

他们20年前不流眼泪吗

美国和加拿大同世界其它国家的过敏症发病率还是很不同的。

Lower Rates of Allergic Disease Found in Children Born Outside the United States Appear to Reverse After Prolonged U.S. Residence
Research from the 2013 Annual Meeting of the American Academy of Allergy, Asthma & Immunology investigated the association between birthplace, length of U.S. residence and rates of asthma, eczema, hay fever and food allergy.

SAN ANTONIO, TX (PRWEB) February 26, 2013

Research presented at the 2013 Annual Meeting of the American Academy of Allergy, Asthma & Immunology (AAAAI) suggests that children born outside of the United States have lower rates of allergic disease, but after prolonged U.S. residence, this reduced prevalence is reversed.

Other studies have demonstrated that allergic disease seems to be less common in certain racial or ethnic groups. Jonathan I. Silverberg, MD, PhD, of St. Luke’s-Roosevelt Hospital Center and colleagues from the State University of New York Downstate Medical Center and Oregon Health Science Center examined a sample of nearly 92,000 children from the 2007-2008 National Survey of Children’s Health to investigate if there was an association between birthplace, length of U.S. residence and rates of asthma, eczema, hay fever and food allergy.

After statistical analysis of the sample, the researchers found that compared with the U.S.-born children, the children born outside the United States indeed had lower rates of these types of allergic disease. When taking into account age, sex, race or ethnicity, household income, residence in urban areas and history of moving to the United States from another country, this was still true.

Dr. Silverberg and colleagues were also interested in the birthplace of the parents and what that would show regarding prevalence rates in the children who were born outside the United States. Their investigation discovered that children who had parents who were also not U.S.-born had lower rates for all of the allergic diseases versus those children whose parents were born here.

“Most interestingly, our research with this sample uncovered that children whose birthplace was outside the United States who then lived here for more than 10 years had higher odds of developing eczema and hay fever when compared with those who had lived here for up to 2 years,” said Dr. Silverberg. “However, we did not find this was true for asthma or food allergy.”

“What we can take away here is that seeing this loss of childhood protection from eczema and hay fever after extended U.S. residence implies that environmental factors may promote the development of allergic disease,” Dr. Silverberg explained.

The AAAAI represents allergists, asthma specialists, clinical immunologists, allied health professionals and others with a special interest in the research and treatment of allergic disease. Established in 1943, the AAAAI has more than 6,700 members in the United States, Canada and 60 other countries.

嗨，你坑我啊，热娜老二。你在我回复之后又加了这些资料。显得我好像故意忽视你这些资料，为争而争似的。
谢谢这些资料。尤其是红字部分。
我的贴里也说了，如果有更详细的资料，能够表示出这50年里的曲线变化，就更能说明问题。简单一句说过敏在过去50年里一直增长，只能说明过敏的增长史早于转基因。
