We often hear about the need to wash our hands thoroughly to prevent the spread of bacteria. However, not all bacteria are created equal. Some bacteria, such as the kinds in your intestines, are actually beneficial to your health. Understanding the role of these bacteria and taking steps to promote healthy gut bacteria can result in an overall improvement in your health.

What is the Difference between “Good” and “Bad” Bacteria?

The word “bacteria” has gotten a bad rap, and that’s because many of these tiny organisms cause disease. However, a bacterium is simply a type of single-celled microorganism detectable only under the microscope. Scientists estimate that there may be between 10 million and 1 billion different species of bacteria, but we only know about a few thousand so far.

Experts differentiate between “good” and “bad” bacteria based on their effects on the human body. Bad bacteria are responsible for a host of diseases, including food poisoning, typhoid fever, tetanus, pertussis (whooping cough), and syphilis. At the same time, our bodies are home to billions of good bacteria that promote health.

Understanding the Bacteria in Your Gut

According to a 2013 article published in Gastroenterology and Hepatology, our intestines are home to 300 to 500 different species of bacteria, with an estimated 100 trillion total microorganisms swarming our gut. That’s more than 3 pounds of body weight due to these thriving bacterial colonies.

Scientists are still discovering ways in which our gut bacteria keep us healthy. They help us digest foods, repress the proliferation of potentially harmful micro-organisms, and stimulate the growth of new cells. Importantly, the gut bacteria also seem to play an important role in immune system functioning. These bacteria stimulate tissues to fight infection and can help the body defend against certain diseases. For example, gut microorganisms may help us better tolerate foods that initially cause some distress. The bacteria in our guts are particularly helpful for people with allergies or certain autoimmune conditions that make them hypersensitive to certain foods.

Promoting Healthy Cultures of “Good” Bacteria in Your Gut

Unlike the color of your eyes, you’re not simply born with a static colony of microorganisms in your intestines. The type and abundance of these organisms is constantly changing depending on your diet and lifestyle. This means that there are things you can do to make your gut a friendly environment in which gut bacteria can live. Consider the following suggestions:

  • Eat Yogurt with Live and Active Cultures.
    Yogurt contains a variety of bacteria, including L. acidophilus, which stimulates digestion and helps the body combat disease. Check the container of your yogurt to ensure that it has live, active cultures.
  • Go Fermented
    Fermented foods contain bacteria that make it through the harsh, acidic environment of your stomach to work their magic in your gut. Eating sauerkraut, miso, or kimchi can aid digestion and improve the health of your gut flora.
  • Eat Fiber-Rich Foods
    Foods naturally high in soluble fiber, such as asparagus, bananas, chicory root, and Jerusalem artichokes, create a welcoming atmosphere for gut bacteria.
  • Find a Supplement
    There are great supplements available that can restore healthy gut flora. This is particularly important after you’ve gotten sick or taken a course of antibiotics, which wipe out good bacteria.
