Prebiotics versus Probiotics
May 24, 2017

From our previous blog post, you might remember that probiotics are healthy or good bacteria that can displace bad bacteria to influence overall health, metabolism, digestion, production of nutrients, immunity, body composition, and more!

What’s the difference between probiotics and prebiotics?

Unlike probiotics, prebiotics are not live organisms. Prebiotics are nondigestible fibre compounds that act as “food” for probiotics. Eating prebiotics stimulates probiotic activity by helping bacteria grow and multiply within the gastrointestinal tract.

When taken together, probiotics and prebiotics work together in a synergistic way to promote the growth of healthy bacteria.

Should I take a prebiotic supplement?

Similar to probiotics, you do not need a supplement for optimal health. Prebiotics supplements are expensive and unnecessary as they can also be found naturally in many different foods, including:

  • Artichokes
  • Bananas
  • Asparagus
  • Garlic
  • Leeks
  • Onion
  • Tomatoes
  • Barley
  • Rye
  • Whole grains
  • Chicory root
  • Dandelion root

Bottom line

Eating food containing prebiotics and probiotics can improve overall health by influencing the balance of good and bad bacteria in your gastrointestinal tract. Eating a healthy diet ensures you are having a good balance of both prebiotics and probiotics.
