Insoluble dietary fiber (IDF) is a nutritional component constituting the building block of plant cell walls. Our understanding of the role of IDF in plant-based foods has advanced dramatically in recent years. In this Review, we summarize research progress on the subtypes, structure, analysis, and extraction methods of IDF. The impact of different food processing methods on the properties of IDF is discussed. The role of gut microbiota in the health benefits of IDF is introduced. This review provides a better understanding of the chemical features and biological functions of IDF, which may promote the future application of IDF in functional food products. Further investigation of the mechanisms underlying the health benefits of IDF enables the development of effective strategies for the prevention and treatment of human diseases.
不溶性膳食纤维（IDF）是构成植物细胞壁的营养成分。近年来，我们对植物性食物中 IDF 作用的理解取得了显著进展。在这篇综述中，我们总结了 IDF 的亚型、结构、分析和提取方法的研究进展。讨论了不同食品加工方法对 IDF 性质的影响。介绍了肠道微生物群在 IDF 健康益处中的作用。本综述提供了对 IDF 的化学特征和生物学功能的更好理解，这可能有助于促进 IDF 在功能性食品产品中的未来应用。进一步研究 IDF 健康益处的机制可以为预防和治疗人类疾病制定有效的策略。
