Maintaining—or restoring to normal—gut barrier function is not currently recognized as a physiologic benefit of fiber consumption, in part due to lack of agreement by experts in the field on how to define and measure normal gut barrier function in human nutrition research. An ILSI North America sponsored expert panel published an article in 2019 summarizing the foundational science related to normal gut structure and function as well as how to measure it. The panel’s recommended next step is to standardize a method for measuring gut permeability in human subjects and apply the method to initiate the process of quantifying the range of distribution in the general healthy public. The objective is to assess whether variation in the range of fiber representing typical to recommended intakes in the American diet is a critical factor in establishing this standardized method.
