Wheat and garlic fertilize the microbiome
Part of the reason that the African diet in O'Keefe's study promotes a healthy gut microbiome may be because of its relatively high levels of a type of fiber called inulin, found in certain plant foods. These foods, which include garlic, leeks, wheat and barley, are "general fertilizers for the microbiome," Spector said.
Inulin helps encourage the gut microbiome to produce butyrate, an acid that feeds cells in the colon and keeps inflammation in check, said Rob Knight, professor in the pediatrics and computer science and engineering departments at UC San Diego. Studies have also suggested that diets high in inulin lead to increases in health-promoting bifidobacteria, which break down carbohydrates to short-chain fatty acids, which may in turn decrease the risk of cancer, digestive and heart disease.

100 trillion bacteria, 10 times more than human cells
The bacterial community in your colon is home to about 100 trillion bacterial cells; there are about 10 times more of these bacterial cells than there are human cells in your body, and they represent a vast number of different species.
