你肯定知道食物过敏和呼吸道过敏。但是,你可能不太了解交叉过敏,比如对苹果和桦树过敏,对猕猴桃和榛子过敏。什么叫交叉过敏?有的孩子是对某种食物过敏,或者对某类食物过敏,这种单纯的过敏一般很容易识别。但如果孩子有“交叉”过敏,就比较难以识别了。因为含有导致过敏的过敏原的食物种类相差很远,或者是与呼吸过敏相交叉,比如花粉过敏。当然,并非所有的过敏都一定是交叉过敏,但是,如果孩子被诊断为食物过敏,专家经常会检查他是不是存在着交叉过敏的可能。
You certainly know that food allergies and respiratory allergies. However, you may not know much about cross-allergies, such as allergies to apples and birch, allergies to kiwi and hazelnuts. What is cross-allergy? Some children are allergic to certain foods, or allergies to certain foods, this simple allergy is generally easy to identify. But if the child has “crossed” allergies, it is harder to recognize. Because the allergens that cause allergies are far from the type of food, or are allergic to respiratory cross-pollination, such as pollen allergy. Of course, not all allergies must be cross-allergic, but if a child is diagnosed with food allergies, experts often check whether he is at risk of cross-allergy.
