Plant lectins or phytohemagglutinins possess potent in vivo biological activities. Some, primarily of the family Leguminosae, have been shown to have deleterious nutritional effects. Little information exists, however, regarding the prevalence of lectins or the specific foods that contain lectins in the United States diet. In the present study the edible parts of 29 of 88 foods tested, including common salad ingredients, fresh fruits, roasted nuts, and processed cereals were found to possess significant lectin-like activity as assessed by hemagglutination and bacterial agglutination assays. Based on this survey and a review of the literature we conclude that dietary exposure to plant lectins is widespread. The spectrum of nutritional consequences of such exposure remains to be determined.
植物凝集素或植物血凝素具有强大的体内生物活性。一些主要来自豆科植物的凝集素已被证明具有有害的营养作用。然而，关于美国饮食中凝集素的流行情况或含有凝集素的具体食物，所知甚少。在本研究中，通过血细胞凝集和细菌凝集试验评估发现，所测试的88种食物中的29种可食用部分，包括常见的沙拉食材、新鲜水果、烤坚果和加工谷物，都具有显著的凝集素样活性。基于这项调查和文献综述，我们得出结论，饮食中接触植物凝集素的情况很普遍。这种接触的营养后果范围仍有待确定。
