Key Takeaways

  • Gut bacteria (i.e., gut microbiota, gut microbiome, or gut flora) is essential to our overall health and affects our bodily functions.
  • Eating foods that contain prebiotics and probiotics can help maintain healthy gut bacteria.
  • Prebiotic foods are high-fiber, non-digestible carbohydrates and natural sugars that feed good gut bacteria (e.g., whole grains, bananas, greens).
  • Probiotic foods contain live microorganism in your gut that help digest foods and improve "good" gut bacteria (e.g., yogurt, kefir, sauerkraut, kimchi, kombucha, pickles, miso, etc.).
  • Prebiotics help probiotics grow and remain in your digestive system.

What is the gut microbiome?

  • Consists of 100 trillion cells in the colon or gut
  • Codependent on our body
  • Digest nutrients
  • Promotes gut immunity
