Prebiotics are indigestible fibers that act as a food source for the healthy bacteria found in your gut. Consuming foods and supplements rich in prebiotics not only helps to maintain the health of your digestive system but also boosts your overall immunity.

Once consumed, prebiotics help the healthy bacteria in your gut produce nutrients like acetate, short-chain fatty acids, butyrate, and propionate, which improve the digestive system’s metabolic health and performance.

Curious to learn more about prebiotics? If so, then you couldn’t be in a better place. Read on as we discuss the best prebiotic foods and supplements you should know about.

Best Prebiotic Foods

Chicory Root

Chicory Root contains 68% inulin, a type of fiber that is indigestible by the human body. The inulin acts as a great source of nourishment for the good bacteria in your gut, which improves digestion while also reducing constipation.

Inulin is a prebiotic fiber known to increase overall bile production, thus improving the body’s ability to digest fat and carbohydrates. Moreover, the antioxidant compounds found in chicory root help protect the liver from potential oxidative damage.

You can buy chicory root at your local grocery shop and eat it as a vegetable after boiling. Ground chicory root is also a well-known alternative to coffee, more so for people looking to reduce their caffeine intake.

Jerusalem Artichoke

Also called earth apple, sunchoke, or sunroot, the Jerusalem artichoke contains approximately one gram of dietary fiber per 50 grams. Consuming this vegetable regularly will almost certainly increase the population of good bacteria in your gut. It is among the most commonly used sources of soluble fibers for prebiotic supplements.

Besides containing high amounts of inulin, Jerusalem artichokes also have high potassium and thiamine levels, which can help improve muscle function, the performance of the immune system, and the nervous system’s overall health.

You can choose to boil the sunroot or eat it raw. But to boost the overall number of prebiotics in your colon, it’s best to consume this vegetable regularly.

Dandelion Greens

The dandelion plant needs no introduction when it comes to healthy living. Rich in calcium, iron, Vitamins C, A, K, and B2, and protein, dandelion consumption is a surefire way to keep the doctor away.

In addition to its numerous nutritional benefits, the dandelion plant also contains high fiber levels (2 grams per 50-gram serving), making it among the best prebiotics. The Dandelion plant is also known to help against inflammation, cancer, and diabetes. The vegetable is commonly used as an ingredient in most prebiotic supplements.

Braising and sautéing are great ways to prepare this prebiotics feed, especially when accompanied with lots of garlic. You can also eat this prebiotic raw as part of a delicious salad.


Garlic contains a high amount of indigestible fiber that promotes the growth of Bifidobacteria in the colon. This common herb contains 11% inulin and 6% fructooligosaccharides (FOS), a naturally occurring (super sweet) prebiotic.

The good thing about garlic is their ease-of-availability as you can easily purchase them without placing an order. Regular garlic consumption is associated with anti-cancer, antioxidant, and antimicrobial benefits. Garlic is also known to prevent the growth of harmful, disease-promoting bacteria.

Consuming garlic shouldn’t be too hard as you can use it in its vegetable form or add it to your meals as a ground spice. For best outcomes, you should normalize including garlic in most, if not all your recipes.


Onions contain 10% inulin and 6% FOS, making them among the best prebiotics around. Eating foods prepared with onions as an ingredient will allow your body to benefit from improved fat breakdown, enhanced immune system functionality, and a healthier digestive system.

The FOS found in this prebiotic is vital in strengthening gut flora, which helps boost the overall nitric oxide production in cells. Nitric oxide is released by all cells and increases blood flow while lowering blood pressure.

Moreover, the presence of quercetin, a flavonoid found in onions, gives the bulb impressive anti-cancer and antioxidant properties, making it among the best prebiotics to consume.


Asparagus is a highly nutritious vegetable commonly used in salads and side dishes. The prebiotic contains approximately one gram of inulin per 50-gram serving. Regular consumption of asparaguses promotes healthy bacteria development in the gut, thus improving your overall digestive health.

Besides the prebiotic fiber`s ability to promote digestive health, it also has powerful antioxidant properties that provide anti-inflammatory benefits when regularly consumed. The vegetable is also known to prevent liver cancer, and regulate blood sugar levels.


The banana plant`s popularity stems from the sweetness of its seedless fruit and its absolute nutritional value. Bananas are rich in minerals, vitamins, and fiber, making them among the most balanced fruits in nutrition.

And while the inulin level in bananas is relatively low compared to the likes of Asparagus, it still serves as a tremendous prebiotic for gut health. Unripe bananas have high resistant starch levels, which means they`ll act as prebiotics once consumed.


Apple makes it to the list of best prebiotics due to its high fiber content. It contains pectin, a prebiotic fiber that increases overall butyrate levels in the colon. Butyrate is a short-chain fatty acid that acts as food for good bacteria.

In addition to high fiber levels, apples are also rich in polyphenol antioxidants, which, together with pectin, help improve fat metabolism, reduce cancer risk and decrease overall cholesterol levels.

It would help if you considered eating or juicing apples every other day to make the most of their anti-inflammatory and antioxidant properties. The prebiotic fiber in apples makes it an excellent food source for the digestive system’s good bacteria.


Whole oats contain resistant starch and beta-glucan fiber in large amounts, making the cereal grain among the best food sources for prebiotics. The beta-glucan found in oats is known to improve the digestive system, reduce LDL cholesterol levels, balance blood sugar levels, and promote healthy gut bacteria development.
Moreover, oats are excellent for weight loss due to their ability to control appetite by slowing down the digestion process. This prebiotic also comes with a host of anti-inflammatory and antioxidant benefits due to its high phenolic acid content.

Konjac Root

Commonly referred to as elephant yam, Konjac root is a tuber well-known for its wide-ranging health benefits. This highly nutritious tuber contains glucomannan fiber (40%), which besides promoting the development of gut bacteria, helps relieve constipation and improve the immune system.

Regularly consuming Konjac roots is associated with improved carbohydrate metabolism, reduced blood cholesterol levels, balanced blood sugar levels, and weight loss. Although you can prepare several recipes using the elephant yam, it is mostly used as a primary ingredient in some prebiotic supplements.
