Prebiotics vs Probiotics
Prebiotics and probiotics sound alike but are different things. Here is a simple guide to what each one is and where each is found.
Prebiotics and probiotics are two terms that come up often in conversations about food. They sound similar, but they are different things. Here is a simple guide to tell them apart.
What Are Probiotics?
Probiotics are live microorganisms, often called "good bacteria." They are found naturally in certain foods, including:
- Yogurt
- Kefir
- Sauerkraut
- Kimchi
Probiotics are also sold as dietary supplements.
What Are Prebiotics?
Prebiotics are non-digestible fibers that serve as food for the bacteria already living in the gut. They are found in certain fruits, vegetables, and whole grains, including:
- Bananas
- Onions and leeks
- Garlic
- Asparagus
- Oats
- Jerusalem artichoke
How They Differ
The simplest way to remember it: probiotics are the bacteria themselves, while prebiotics are the food those bacteria use.
