Clinical Trial Summary

The gastrointestinal (GI) tract is a central hub for human health given its essential role in nutrient absorption, waste production and immunity. Diet is a major contributor to gut health including affecting the incidence and severity of GI disease. This is mediated, at least in part, by the presence of microbiota, a highly diet-dependent biome. In fact, dietary changes are capable of altering bacterial populations and/or microbial metabolism, which in turn, controls the type and abundance of small molecules being produced in the gut, many of which can exert biological effects. Several lines of evidence suggest that dietary protein in particular, can impact gut health. Therefore, this trial will test whether dietary protein type differentially impacts gut function in humans by carrying out a single-blinded randomized cross-over controlled feeding study in healthy individuals. Subjects will be provided with an individualized very low protein diet augmented with pea- or egg white-derived protein supplements, as their major protein source. The impact of consuming pea vs. egg white protein on 1) the fecal metabolome, 2) gut barrier function and 3) gastrointestinal symptoms will be determined.

Outcome

Type Measure Description Time frame Safety issue
Primary Fecal metabolome Mass-spectrometry based analysis of the relative abundance of metabolites will be carried out on feces. This analysis will be carried out at baseline and the end of each treatment period, entailing 4 measurements over an approximately 36 day period
Primary Intestinal permeability Subjects will undergo lactulose-mannitol test to inform on gut permeability This analysis will be carried out at baseline and the end of each treatment period, entailing 4 measurements over an approximately 36 day period
Secondary Adherence to study diets consumption of study diets will be recorded through subject-reported surveys before and after eating. Daily over two, 10-day periods
Secondary Amount of study diets consumed Subjects will take pictures of food items before and after eating to assess the amount of each study diet item consumed. Daily over two, 10-day periods
