“Now, this is a landmark study exploring the relationship between the gut microbiome, food intake, and overall health is this paper from Justin Sonnenburg's lab and Chris Gardner's lab, both of which are at Stanford. And the paper entitled "Gut Microbiome-Targeted Diets Modulate Human Immune Status" was published in the journal "Cell", which is among the three top journals perhaps in the world, "Nature", "Science", and "Cell" really being the apex journals for overall science, and especially for biomedical sciences.”
