Powering your gut: the benefit of prebiotics.

Updated: Jul 9, 2023

Trillions and trillions of microbes inhabit our guts. The exact number is unknown, but researchers estimate that our gut has between 30-400 trillion microbes. And did you know, that just like us, they also get hungry! They need to eat to survive and thrive. This is the purpose of prebiotic foods.

Prebiotics are food for the beneficial bacteria in our gut.

They have specific types of dietary fibers which we cannot digest. Instead, these fibers pass through our digestive system and enter the colon. Once in the colon, the gut bacteria feast on these prebiotic fibers and create a number of beneficial postbiotic byproducts such as short-chain fatty acids (SCFAs).

The most common SCFAs are acetate, propionate and butyrate. They have many health benefits:

  • they serve as an energy source for the cells of the colon

  • they can regulate metabolism, stimulate hormone production, regulate blood sugar and regulate appetite

  • they have anti-inflammatory, antitumorigenic and antimicrobial effects

  • they can modulate the immune system in a beneficial balanced way

  • they can regulate gene expression

When you sit down for your next meal, look at the food not only in terms of your own enjoyment and health, but also as food for your gut bacteria. As you feed the beneficial microbes with prebiotics, they will flourish and will inhibit the growth of harmful microbes. This helps to maintain a diverse and balanced microbiota.

A diverse microbiota has many health benefits, some of these include:

  • maintaining a strong gut barrier

  • reducing leaky gut

  • reducing systemic inflammation

  • reducing chronic disease

  • reducing fungal overgrowth

  • reducing the impact of viral infections

  • creating a strong and balanced immune system

Prebiotics are found in most fruits and vegetables.

Some of the best sources of prebiotics include...






bell pepper




chicory root





jicama, leek, mushroom, pea, radish, sweet potato, yam.


apple, avocado, blueberry, banana, cherry, dragon fruit, kiwi, lemon, lime, mango, mulberry, pear, pomegranate, plantain, raspberry, strawberry, watermelon, and more!


Chia seeds, flax seeds, hemp seeds, pumpkin seeds, legumes, quinoa, wild rice.


Burdock root, chives, cumin, dandelion root, ginger, parsely, thyme, tumeric, oregano.


As you can see, there is a wide range of options to choose from.

Research shows that the best indicator of a healthy microbiome is the diversity of whole plant foods in your diet. It is recommended to eat a MINIMUM of 30 plant foods each week. This can be easy when you include fruits, vegetables, whole grains, legumes, raw nuts and seeds, herbs, and spices. These foods are not only delicious but also provide the nourishment your gut bacteria need to thrive.

So get busy in the kitchen, add new flavors, and have fun!

By taking care of your gut health

you are taking care of your overall health.
