* An allergic reaction occurs when your body's immune system reacts to a
foreign substance ('allergen') such as pollen or dust.
* In response to the allergen, your body releases a chemical called
histamine that causes symptoms such as a runny nose, itchy eyes and sneezing.
PREVENTING ALLERGY SYMPTOMS
* The best thing is to know what triggers your symptoms and avoid them.
* Allergy triggers are substances like pollens and dust, which cause

so now if i go back to china, the process will start all over again, then i
will have 4-5 yrs of allergy free period? but for the 17 yrs spent in china,
i've not had any allergic symptoms, not to me knowledge,
i guess there might be something in the diet here that somehow play a role
in it,

but I have a couple friends who moved back to China suffering from weird
allergy to what they were once ok with.
american food has too much防腐剂添加剂和颜料...
有报导说食用色素可以增加过敏的机会,尽管他们本身不致敏, 但其体内代谢过程
可以产生类似半抗原的物质,大大增加了过敏机会.
还有在过于干净的环境生活也容易过敏赫赫
还有转基因食品的安全性也让人疑虑.
不过回中国那么多好吃的,就算稍有过敏也值得...^_^
