    摘要:

    本文旨在从不同角度评估每日食用柿子后胃结石的形成风险。在模拟胃液体系中证实,柿单宁与食物成分的絮凝作用不能等同于其结石形成风险。在动物体系中,SD大鼠30天持续摄入柿子后,经胃部解剖均未观察到结石,并且胃分泌功能和胃病理特征无明显变化。此外,志愿者试验和产区问卷调查进一步证实,健康成人每天食用两个柿果(400-500 g)未出现胃结石。综合而言,本研究初步证实健康成人每日食用两个柿果不会导致胃结石。

    Abstract:

    For a long time, whether eating persimmons can lead to gastric bezoars was controversial. The public's concerns about eating persimmons have severely restricted the development of persimmon industry. However, until now, no systematic studies have confirmed that eating persimmons can cause bezoars. Therefore, this study aimed to evaluate whether daily consumption of persimmon fruits could cause gastric bezoars. In stimulated gastric fluid system, we confirmed that the flocculation ability of tannins with food ingredients cannot been considered for its bezoars formation risk. In the animal system, our results showed that no bezoars were found in the stomach, and no intracorporal pathogenic properties were observed according to the hematological and stomach parameters after 30 days’ continuous intake of persimmon. Additionally, both volunteer tests and questionnaires in typical persimmon growing region revealed that consuming two persimmon fruits (400-500 g) daily for healthy person did not lead to gastric bezoars. Altogether, this study preliminarily confirmed that healthy adults eating two persimmons daily did not cause gastric bezoars.
