A lovely article written by Jill Weisenberger:
Trillions of microorganisms inhabit your intestines. There are 10 times more bacterial cells than human cells in your whole body! Fiber-rich plant foods give bacteria a fighting chance. Fiber feeds the healthy, hungry microbes, so that’s one of many reasons you should have lots of high-fiber plant foods, including grains, legumes, fruits and vegetables, on your plate. Eating wisely is likely your best strategy for boosting the beneficial bugs. Fermented foods provide healthy bacteria. Eating fermented foods that contain live cultures can add healthy microbes to your intestines. The most common fermented food in the U.S. is yogurt. But read labels carefully when adding fermented foods to your diet because not all contain live cultures.
How to boost friendly bacteria
Eat more whole, fiber-rich plant foods, such as whole grains, legumes, fruits, vegetables, nuts and seeds.
Include fermented foods, such as live cultured yogurt, pickles and sauerkraut in your diet.
Consider taking a probiotic supplement, beverage or food.
