A number of vegetables provide prebiotics, including jicama, artichokes, asparagus, garlic, leeks, onions, chicory root, Jerusalem artichokes and dandelion greens, as well as other leafy greens.
In diet, prebiotics are typically non-digestible fiber compounds that pass undigested through the upper part of the gastrointestinal tract and stimulate the growth or activity of advantageous bacteria that colonize the large bowel by acting as substrate for them.
