A new study, published in the journal Frontiers in Behavioral Neuroscience, discovered that such popular vegetables as onions, leeks, and artichokes help humans to relax and have a better sleep at night. These plants are high in prebiotics and fiber.
For the study, a team of scientists fed 3-week-old male rats a diet of either standard chow or chow with prebiotics. The rats that consumed prebiotics spent more time in rapid-eye-movement sleep.
The researchers from the University of Colorado Boulder that executed the study say: “It is possible that a diet rich in prebiotics started in early life could help improve sleep, support the gut microbiota and promote optimal brain/psychological health.”
