Your gut is home to trillions of microorganisms that influence everything from digestion and immunity to mood and energy. You have probably heard of probiotics, but prebiotics and postbiotics are just as important, and often overlooked. Understanding the difference can help you make smarter choices about what you eat and how you support your gut every day.
What Are Prebiotics?
Prebiotics are a type of dietary fibre that feeds the beneficial bacteria already living in your gut. They are not digested by your body, so they travel to the colon where your gut bacteria ferment them and use them as fuel.
Common prebiotic foods include:
-
Garlic and onions
-
Leeks and asparagus
-
Bananas (particularly slightly underripe ones)
-
Oats
-
Legumes such as lentils and chickpeas
Think of prebiotics as the soil. Without good soil, even the best seeds cannot thrive.
What Are Postbiotics?
Postbiotics are the byproducts produced when your gut bacteria ferment prebiotics. They include compounds like short-chain fatty acids, enzymes, and cell wall fragments. These substances have a direct effect on your health, helping to reduce inflammation, strengthen the gut lining, and regulate immune responses.
Postbiotics are increasingly being studied for their role in supporting people with sensitive digestive systems, as they deliver many of the benefits of live bacteria without requiring a living microorganism.
Prebiotics vs Postbiotics: What Is the Difference?
Prebiotics are the input. Postbiotics are the output. You need the first to get the second. When you eat prebiotic-rich foods, your gut bacteria get to work fermenting them, and postbiotics are what gets produced in the process.
Neither is better than the other. They work as part of a system. Probiotics (the live bacteria) need prebiotics to survive and thrive, and together they produce postbiotics that do the real work at a cellular level.

Frequently Asked Questions
Do I need to take prebiotic and postbiotic supplements?
Not necessarily. A diet rich in diverse whole- foods naturally supports both prebiotic intake and postbiotic production. Supplements can be useful in specific situations, but food first is always the FoodGrown approach.
Are postbiotics safe for people with gut sensitivities?
Yes, postbiotics are generally well tolerated, even for people who struggle with probiotics or high-fibre foods. They deliver beneficial compounds without requiring live bacteria.
What is the difference between prebiotics and probiotics?
Probiotics are live beneficial bacteria. Prebiotics are the food that feeds those bacteria. Both are necessary for a healthy gut ecosystem.
Which foods are highest in prebiotics?
Garlic, onions, leeks, asparagus, oats, bananas, and legumes are among the richest sources of prebiotic fibre.
Can I get postbiotics from fermented foods?
Fermented foods like kefir, yoghurt, sauerkraut, and kimchi contain postbiotic compounds because of the fermentation process, making them excellent additions to a gut-supportive diet.
