Buckwheat allergy and reports on asthma and atopic disorders in Taiyuan City, Northern China. Asian Pacific Journal of Allergy and Immunology. 2000 Sep; 18(3): 147-52http://imsear.searo.who.int/handle/123456789/36940Published by the Allergy and Immunology Society of Thailand.Allergy to common buckwheat (Fagopyrum esculentum) has been reported from Europe and Japan, and a 24 kDa globulin protein has been identified as one of the major allergens. In China also another type, tartary buckwheat (Fagopyrum tartaricum) is grown and consumed. Three groups of individuals in Shanxi province, China, were investigated for buckwheat allergy using skin prick test. The groups were: agricultural researchers with occupational exposure to buckwheat (N = 16); workers in a food industry producing buckwheat noodles (N = 25), and patients with diabetes or cardiovascular disease consuming buckwheat as functional food (N = 20). Information on atopic disorders and adverse food reactions were collected by a doctors-administered questionnaire. One male industrial worker had a positive skin prick test to buckwheat, but no symptoms while eating or handling buckwheat products. In total, 34% consumed buckwheat food at least every week, and 23% had a weekly consumption of tartary buckwheat. The prevalence of doctor's diagnosed asthma was low (1.6%). Four subjects (6.6%) reported a history of allergic rhinitis, with allergy to cedar pollen, carnation and peach.engAdultAgricultural Workers' DiseasesAsthma --epidemiologyChina --epidemiologyDust --adverse effectsFagopyrum --adverse effectsFemaleFood Hypersensitivity --epidemiologyHumansHypersensitivity, Immediate --epidemiologyMaleMiddle AgedOccupational Diseases --epidemiologyPrevalenceResearch PersonnelRespiratory Hypersensitivity --epidemiologyRhinitis, Allergic, Perennial --epidemiologySkin TestsTime FactorsJournal Article
