"虽然我们发现10%的成人食物过敏,但却有近2倍的成年人觉得他们患有食物过敏(实际上,他们的症状只是食物不耐受或其它与食物相关的疾病的表现),"西北大学伯格医学院、研究的首席作者鲁敇·古普塔在一次资讯发布会上解释道。
While these adults may actually believe they have a food allergy, the symptoms they reported were not reflective of true allergic reactions. Most likely, they were experiencing other unwelcome symptoms-like diarrhea, abdominal pain, or bloating-from a food sensitivity or intolerance. Food allergy symptoms are caused by an immune system response; symptoms of intolerances or sensitivities are not. Someone with a food intolerance is missing a digestive enzyme that would break down a part of the food. Food sensitivities aren't as clearly defined, but they usually involve an upset stomach after eating a specific food.
虽然这些成年人或许真的觉得自己患食物过敏,但他们自己所描述的症状实际并不是过敏的真正反映。他们很有可能是因为对食物敏感或食物不耐受,才表现出这些难受的症状--比如腹泻、腹痛或腹胀。与食物不耐受或食物敏感的症状所不同的是,食物过敏症状是由免疫系统反应引起的。患有食物不耐受的人体内缺少一种可以分解部分食物的消化酶。食物敏感的定义尚不明确,但通常指的是,摄入特定食物之后,胃部不适。The body's immune system overreacts to proteins that [their bodies perceive as] unhealthy and attacks them as a threat to the body. The reaction to this faulty immune response leads to symptoms like itching, tightening of your throat, or shortness of breath."
