Detailed Description
Detailed research aim of this controlled, randomized crossover postprandial clinical study are:
- To study the impact of complex plant- and animal-based foods on glucose metabolism, acute inflammation, and markers of microbial fermentation of fiber and proteins.
- To investigate the difference in the gut mediated metabolism induced by naturally occurring fiber fraction bound plant protein or by plant protein with added fiber when compared to animal protein.
- To conduct in vitro experiments using fecal samples from participants in the meal study to investigate the distinctions between different animal and plant proteins on both host and microbial metabolites, as well as the function of the gut barrier.

|
|
Placebo Comparator: Meal 3
Low protein and low fiber cereal
|
The control meal is low fiber and low protein meal.
