Understanding the epidemiology of food allergy is complicated by the difficulty of identifying it on a large scale. The prevalence of food allergy is higher in younger age groups and decreases with age. Allergy to peanut and egg seems to be more common in Northern Europe, the United States, Canada and Australia compared with Southern Europe, Eastern Europe and Asia, whereas shellfish and fish allergies may be more common in Asia. The rate of transient unrecognized food allergy may be high and variable recognition of food allergy may explain some of the differences seen in food allergy prevalence.
由于难以大规模识别食物过敏，了解其流行病学情况变得复杂。食物过敏在较年轻年龄组中的患病率较高，并随年龄增长而降低。与南欧、东欧和亚洲相比，花生和鸡蛋过敏在北欧、美国、加拿大和澳大利亚似乎更为常见，而贝类和鱼类过敏在亚洲可能更为常见。短暂未识别的食物过敏发生率可能很高，对食物过敏的不同识别情况可能解释了食物过敏患病率中出现的一些差异。
