The gut microbiome consists of 100 trillion live bacterial microbes, both ‘good’ and ‘bad’, that influence nutrient absorption, metabolism, immunity, mental health, how well we sleep and even whether or not we get spots.

It found that gut bacteria might influence sleep patterns by helping to create important chemical messengers in the brain, such as mood-boosting serotonin and dopamine.​

Here, we’ll take a closer look at prebiotics vs probiotics, what the key differences are between them, and how they can both benefit us. ​

PREBIOTICS VS PROBIOTICS: WHAT’S THE DIFFERENCE?​

“Probiotics are beneficial or ‘good’ live bacteria that have the ability to restore and improve your gut microbiome, or gut flora,” says gut health specialist Marilia Chamon, founder of You do not have permission to view the full content of this post.

“Prebiotics, on the other hand, are non-digestible dietary fiber that act as food for good gut bacteria. You can find them in certain foods or supplements. Probiotics are transient, meaning they will survive in the gut for a short period of time, but do not set up residency. By feeding them prebiotic fiber, we give them the fuel they need to colonize the gut and improve digestive health.”​

PREBIOTICS VS PROBIOTICS: WHERE CAN YOU FIND THEM?​

Chamon recommends eating a variety of the following foods to gain prebiotics. Each contains unique fibers which the different microbes in your gut like to feed on. This is one of the best ways to increase your microbial biodiversity, which is crucial for a healthy gut.​

• Artichokes​

• Onions​

• Garlic​

• Asparagus​

• Leeks​

• Unripe/green bananas​

For probiotics, Chamon advises consuming a variety of cultured and fermented foods, including those listed below. ​

• Yogurt​

• Kefir​

• Sauerkraut​

• Kimchi​

• Miso​

• Kombucha​

• Pickles​

“These are a dietary source of live bacteria that can favorably alter the gut’s microbial balance,” she says. “This is because they offer high concentrations of digestive enzymes – produced during the fermentation process by microorganisms in the food – so they can assist with the digestion of simple and complex carbohydrates including fiber, proteins and fats.”​

But when is it best to opt for a prebiotic vs probiotic? “Probiotic-rich foods can help to improve gut bacteria diversity and taking supplements can be used as a therapeutic tool to address specific symptoms, for example: bloating, constipation, diarrhea,” says Chamon.​

She recommends, however, only using specific strains of probiotics that have been researched and proven to help with certain gut-related symptoms.​

“Prebiotics, on the other hand, feed probiotics – for this reason, it is important to eat a varied plant-oriented diet, rich in prebiotic fiber. Prebiotic supplementation can also be helpful for those that struggle to eat enough fiber, with daily recommended intake in the US being 25-30g.”​

WHAT ARE POSTBIOTICS?​

“Postbiotics are beneficial compounds made when the friendly bacteria in your gut – probiotics – digest and break down dietary fiber – prebiotics,” explains Chamon. “Some of the most important postbiotics are called Short Chain Fatty Acids (SCFAs) and these play important roles in our gut health by keeping the gut environment stable and nourishing beneficial bacteria. They also stop opportunistic bacteria from entering our intestinal ecosystem and sticking around.”​
