我们吃了食物,食物中的蛋白质,在体内必须先经酶的作用,水解成为氨基酸,然后才能被身体吸收利用。但有时微量的蛋白质也可以被吸收。在有过敏性的人,体内如吸收了微量的异性蛋白质以后,即产生过敏性疾病(Allergy),而发生哮喘、湿疹、枯草热、呕吐等症状。这种能产生过敏性疾病的蛋白质,各人不同,有些人吃了某种动物性的蛋白质,会产生过敏性疾病;也有些人吃了某种植物性的蛋白质,产生过敏性疾病;同时有些人并不一定因吃蛋白质。经呼吸道或皮肤接触也可产生。此外,还有些人吃了某种药,也会产生过敏性疾病,依据Wolff-Eisner氏的学 We eat food, protein in food, in the body must be the role of enzymes, hydrolysis into amino acids, and then be absorbed by the body. But sometimes trace amounts of protein can also be absorbed. In an allergic person, the body absorbs a trace of heterosexual protein, which produces allergic diseases (Allergy), and the occurrence of asthma, eczema, hay fever, vomiting and other symptoms. This can produce allergic diseases, different proteins, some people eat some animal protein, can produce allergic diseases; some people eat some vegetable protein, produce allergic diseases; while some People do not necessarily eat protein. Respiratory or skin contact can also be produced. In addition, some people eat some kind of medicine, can also produce allergic disease, according to Wolff-Eisner’s study
