Prebiotic Plant Fibers Benefit Good Gut Bacteria And Improve Sleep

March 23, 2017: 12:00 AM EST
Nondigestible plant fibers, on which good bacteria in the human gut feed, seem to have an impact on sleep, according to new U.S. research. Fibers found especially in plants like chicory, artichokes, raw garlic, leeks and onions, improve non-REM (non-rapid-eye-movement) sleep and REM sleep by buffering the physiological impact of stressful events. The study found that rats fed a prebiotic diet spent more time in restful, restorative non-REM sleep. The findings show that when beneficial bacteria digest prebiotic fiber, they multiply, improving overall gut health, and release metabolic byproducts that influence brain function.
