Probiotic-rich foods such as yogurt, sauerkraut and miso contain good bacteria. Brine-pickled vegetables, sourdough, tempeh and probiotic dairy products are also meaningful sources of good bacteria. Prebiotic-rich foods such as legumes, honey and apple cider vinegar help support the proliferation of healthy gut flora by providing nourishment for good bacteria.
Probiotics are good microorganisms that live in the gut and help fight off bad, illness-causing microorganisms. A prebiotic is a hardy dietary fiber upon which probiotics feed so that they can thrive and multiply. Consuming probiotics and prebiotics can help boost metabolism, strengthen the immune system, balance pH levels and reduce gas.
