Did you know that your body’s overall health depends on the bacteria in your gut? It’s true! We have more bacteria in our GI tract than we have cells in our bodies. Collectively, these colonies of gut bacteria are called the microbiome. Scientists estimate the average person has 100 trillion micro-organisms in their gut. About 500 different species have been identified, but only 20 types make up 75% of the total.
Many of these bacteria are beneficial, but we can have bad bacteria too. Good bacteria are protective. They help us break down food, absorb nutrients, and guard our immune system. On the other hand, bad bacteria produce toxins that wreak havoc in the body.
Optimum health depends on minimizing bad bacteria. We do this by encouraging more good bacteria to grow, so they crowd out the bad kind. And also, by eliminating the things that damage our gut and feed bad bacteria.
Fermented Foods Promote a Healthy Microbiome
To improve the health of our microbiome, we first need to protect the good bacteria we already have by eating foods that help good bacteria flourish. These include foods that contain prebiotics, which is a type of soluble fiber found in certain plant foods like garlic, onions, and asparagus. Our microbiome also thrives on probiotics, which are living bacteria found in fermented foods like sauerkraut, kimchi, yogurt, and even dark chocolate. Continue reading
