Know your food
中国人吃什么最容易过敏？
People in China are becoming more allergic
Does your mouth itch (发痒) after eating mango? Be careful! You might be allergic (过敏的) to mangoes.
A new study showed that food allergies affected (影响) 8 percent of Chinese people from 2009 to 2018. The number was 5 percent from 1999 to 2008. Food allergies are increasing among Chinese people!
What it is and why it increases
Allergies are an overreaction (过度反应) of our body’s immune system (免疫系统). The body mistakes the food for something harmful (有害的) and starts fighting. For some people, an allergic reaction may not be too serious, such as itching or swelling (肿大) of the mouth. It could go away soon. But some people could have serious reactions like finding it hard to breathe or even passing out. These are life-threatening reactions and people need to see a doctor as soon as possible.
Scientists don’t know why food allergies are increasing all over the world. But one leading theory is that our immune system needs to “meet” germs (细菌). Then they can learn to tell between bad germs and good foods. However, the world we live in is becoming increasingly cleaner. So the immune system can’t learn it well.
What we can do to avoid it
You are more likely to be allergic to certain foods if some members of your family are. And if you’re already allergic to one food, it may be more likely that you’ll be allergic to another, according to US hospital Mayo Clinic.
There’s still no way to cure (治疗) food allergies today. The best way to deal with it is to avoid the allergens (过敏原). You can have an allergy test to learn whether your body is allergic to something. You should also read food packages (包装) carefully to protect yourself from eating the allergens.
The most common food allergens
Chinese scientists wrote in a new study that Chinese people are more likely to be allergic to seafood, and less likely to be allergic to peanuts compared to people in the United States and Europe. Let’s take a look at the 7 most common food allergens in China. The data is based on a study of nearly 21,000 people aged 6 to 10 and 18 to 70 in Jiangxi province.

了解你的食物
你的嘴在吃了芒果之后发痒吗？小心！你可能对芒果过敏 。
一项新的研究表明，从2009年到2018年，食物过敏影响了8%的中国人。从1999年到2008年，这个数字是5%。中国人对食物过敏的人数正在增加！
它是什么以及为什么会增加
过敏是一种我们身体的免疫系统的过度反应. 身体把食物误认为有害的东西，然后开始战斗。对一些人来说，过敏反应可能不太严重，例如瘙痒或口腔肿大。它可能很快就会消失。但有些人可能会有严重的反应，比如呼吸困难，甚至昏迷。这些都是危及生命的反应，人们需要尽快去看医生
科学家们不知道为什么食物过敏在全世界都在增加。但一个主要的理论是，我们的免疫系统需要“遇到”细菌. 然后他们可以学会区分坏细菌和好食物。然而，我们生活的世界正变得越来越清洁。所以免疫系统不能很好地学习它。
我们可以做些什么来避免它
如果你的家人对某些食物过敏，你就更有可能对其过敏。据美国医院梅奥诊所（Mayo Clinic）称，如果你已经对一种食物过敏，那么你更有可能对另一种食物敏感。
今天，食物过敏仍然无法治愈。最好的方法是避免过敏原. 你可以做一个过敏测试，看看你的身体是否对什么东西过敏。你还应该仔细阅读食品包装以保护自己避免吃到过敏原。
最常见的食物过敏原
中国科学家在一项新的研究中写道，与美国和欧洲的人相比，中国人对海鲜过敏的可能性更大，对花生过敏的可能性更小。让我们看看中国最常见的7种食物过敏原。这些数据是基于对江西省近21000名6至10岁和18至70岁人群的研究得出的。
