Prebiotics

In nutritional terms, prebiotics are:

Non-digestible food ingredients:
- Specifically, they are typically types of fiber that humans cannot digest.
- They pass through the upper part of the gastrointestinal tract undigested.
Food for beneficial gut bacteria:
- Prebiotics serve as a food source for the beneficial microorganisms (probiotics) residing in the gut.
- By nourishing these bacteria, prebiotics promote their growth and activity.
Promoters of a healthy gut microbiome:
- A healthy gut microbiome is essential for various aspects of health, including digestion, immune function, and overall well-being.
- Prebiotics contribute to this by fostering a favorable environment for beneficial bacteria to flourish.
Found in various foods:
- Common food sources of prebiotics include:
  - Onions
  - Garlic
  - Leeks
  - Asparagus
  - Bananas
  - Oats
  - Barley
  - Jerusalem artichokes.
Their role in health:
- By supporting the growth of beneficial bacteria, prebiotics can:
  - Improve digestive health.
  - Enhance mineral absorption.
  - Strengthen the immune system.

Essentially, prebiotics are the fuel that helps maintain a healthy population of beneficial bacteria in your gut. Sources and related content

Are prebiotics and probiotics the same?

No, probiotics and prebiotics are not the same, though they work together to support a healthy gut. Here’s a simple way to understand the difference:

Probiotics:
- These are live beneficial bacteria.
- They add to the population of good microorganisms in your gut.
- Think of them as the “good bacteria” themselves.
Prebiotics:
- These are non-digestible food ingredients, typically fiber.
- They act as food for the beneficial bacteria in your gut, helping them to grow and thrive.
- Think of them as “food for the good bacteria.”

In essence:

Therefore, while both contribute to a healthy gut microbiome, they play different roles.
