食物过敏和食物不耐受： 它们一样吗？
上次更新时间： 2018年9月18日 | 3 分钟阅读时间
食物过敏和食物不耐受之间的区别可以根据您身体的反应来辨别。对某些食物（如乳糖）的身体反应很常见，但大多数情况是由食物不耐受而非食物过敏引起的。
食物不耐受会引发一些与食物过敏类似的反应，因此人们经常会将两者混淆。
什么是食物过敏？
食物过敏是指人的免疫系统将食物中的某种成分误认为是有害的入侵者，并产生一种防御系统（抗体）来对抗它。在某些情况下，食物过敏反应会危及生命。最常见的食物过敏是鱼、贝类、坚果、鸡蛋、花生和牛奶。
什么是食物不耐受？
食物不耐受是由于缺乏完全消化某些食物所需的酶。与食物过敏相比，食物不耐受的症状一般不太严重，出现的时间也较长。对牛奶和其他乳制品中的乳糖不耐受是最常见的食物不耐受。
如果您出现过敏反应或不耐受的严重症状，请立即前往急诊科或呼叫救护车。
