A method to foster healthy intestinal bacteria is usually to eat more like the foods these bugs prefer to eat—namely, fiber. Drinking plant fibers from vegetables, fruits, legumes, wholesome grains, nuts, and seeds resemble filling a bird-feeder with the sort of seeds that the beautiful songbirds you desire attract just like best buy. If you feed them, they will come!

If we wish to attract a lot of several types of songbirds—er, bacteria—then we wish to set out a variety of foods. This means you don’t are just looking to get all your fiber from a single source, for example, a fiber supplement. You want to get it fiber from lots of various kinds of vegetables, fruits, legumes, grains, nuts, and seeds.
Another way to nurture a healthy gut is to consume foods that incorporate beneficial bacteria. This includes stuff like yogurt, kefir, as well as other cultured dairy products; kim-chi, sauerkraut, and other fermented vegetables; miso, tempeh, natto, along with other fermented soy products; and kombucha, which is certainly a kind of fermented tea.
Now, in all honesty, it’s not entirely clear specifically how many of those bacteria survive their trip through the large intestine and set up permanent housekeeping within the gut. But even if they should are simply passing through, they appear to be the most suitable brand of houseguest that will leave the location just a little more than they found it.
