Research on the nutritional aspects of dietary plant fibers in human nutrition has been plagued by many problems of definition, terminology, analytical procedures, as well as insufficient consideration of the interactions of other dietary components with the dietary fiber polymers. The use of the term non-nutritive has also led to some confusion, as many polymers of dietary fiber are digested by intestinal bacteria in humans. It appears extremely important for the orderly progress of this field that comprehensive terms be used cautiously and that perhaps a new umbrella term (such as plantix) should be introduced. The physiological effects of various polymers have been shown to differ considerably; thus the effect of dietary fiber should not be generalized. Analytical procedure should include both water-insoluble and water-soluble fractions and some consideration should be given to the non-polymeric, enzyme-indigestible compounds such as certain seed and leaf waxes.
人类营养中膳食植物纤维的营养方面研究一直受到诸多问题困扰，包括定义、术语、分析方法，以及对其他膳食成分与膳食纤维聚合物相互作用的考虑不足。“无营养的”这一术语的使用也造成了一些混淆，因为许多膳食纤维聚合物可被人体肠道细菌消化。对于该领域的有序发展而言，谨慎使用综合术语显得极为重要，或许还应引入一个新的统称（如“植物素”）。已表明各种聚合物的生理效应差异很大；因此，膳食纤维的作用不应一概而论。分析方法应包括水不溶性和水溶性部分，还应考虑某些种子和叶蜡等非聚合、酶难消化的化合物。
