Tropical fruits are popular because of their unique, delicious flavors and good nutritional value. Polyphenols are considered to be the main bioactive ingredients in tropical fruits, and these exert a series of beneficial effects on the human gastrointestinal tract that can enhance intestinal health and prevent intestinal diseases. Moreover, they are distinct from the polyphenols in fruits grown in other geographical zones. Thus, the comprehensive effects of polyphenols in tropical fruits on gut health warrant in-depth review. This article reviews, first, the biological characteristics of several representative tropical fruits, including mango, avocado, noni, cashew apple, passion fruit and lychee; second, the types and content of the main polyphenols in these tropical fruits; third, the effects of each of these fruit polyphenols on gastrointestinal health; and, fourth, the protective mechanism of polyphenols. Polyphenols and their metabolites play a crucial role in the regulation of the gut microbiota, increasing intestinal barrier function, reducing oxidative stress, inhibiting the secretion of inflammatory factors and regulating immune function. Thus, review highlights the value of tropical fruits, highlighting their significance for future research on their applications as functional foods that are oriented to gastrointestinal protection.
热带水果因其独特、美味的风味和良好的营养价值而广受欢迎。多酚被认为是热带水果中的主要生物活性成分，它们对人体胃肠道发挥一系列有益作用，可以增强肠道健康，预防肠道疾病。此外，它们与其他地理区域生长的水果中的多酚不同。因此，有必要深入研究热带水果中的多酚对肠道健康的综合影响。本文首先综述了几种代表性热带水果（芒果、鳄梨、诺丽果、腰果、西番莲和荔枝）的生物特性；其次，介绍了这些热带水果中主要多酚的类型和含量；第三，讨论了这些水果多酚对胃肠道健康的影响；最后，探讨了多酚的保护机制。多酚及其代谢物在调节肠道微生物群、增加肠道屏障功能、减轻氧化应激、抑制炎症因子分泌和调节免疫功能方面发挥着重要作用。因此，本文强调了热带水果的价值，突出了它们作为以胃肠道保护为导向的功能性食品的未来研究意义。
