Let’s start by understanding the fact that probiotics and prebiotics are different. Probiotics contain bacteria that live in your body and help your gut to break down food.

Prebiotics, on the other hand, are food for these healthy bacteria. Prebiotics contain a type of dietary fiber. For instance, fiber inulin present in banana, chicory root, and asparagus is prebiotic.

You can also purchase prebiotics as a capsule supplement or a commercial food additive.

Here is how prebiotics benefits you.

Types of Prebiotics

There are various types of prebiotics. While the majority of the prebiotics are a subset of carbohydrate groups and are mostly oligosaccharide carbohydrates (OSCs), there is prebiotics from non-carbohydrate sources as well.

Some common prebiotics includes:

  1. Fructans: Consists of inulin and fructo-oligosaccharide or oligofructose. They can stimulate lactic acid bacteria.

  2. Galacto-oligosaccharides: They are the product of lactose extension and can stimulate Bifidobacteria and Lactobacilli.

  3. Glucose and starch-derived oligosaccharides: They include resistant starch and polydextrose, respectively. They may stimulate Bifidobacteria.

  4. Other oligosaccharides: They are known as pectic oligosaccharides.

  5. Non-carbohydrate oligosaccharides: A good example is Cocoa-derived flavanols that stimulate lactic acid bacteria.

Benefits of Prebiotics

Prebiotics, on their own, don’t seem to have many benefits. It is only when prebiotics are used in conjunction with probiotics, that it is beneficial. Some conditions where prebiotics and probiotics are effective are:

  • Diarrhea

  • Irritable Bowel Syndrome

  • Common cold

  • Allergic Disorder

  • Obesity

  • Inflammatory arthritis

Side-effects of Prebiotics

Prebiotics are generally safe and are not seen to cause any major side effects in the majority of cases.


Probiotics are generally taken along with probiotics. Some of their common side-effects are:

  • Loose stool

  • Gas and abdominal bloating

  • Loss of appetite

  • Acid reflux

A severe allergic reaction can also be a side effect if you are allergic to bacteria that are introduced into your body.

Prebiotics Foods

Some common sources of prebiotics are:

  • Legumes

  • Oats

  • Beans and peas

  • Bananas

  • Berries

  • Asparagus

  • Garlic

  • Onions

Interesting fact:

“While all prebiotics are fibers, not all fibers are prebiotics..”
