An Introduction to Probiotics and Prebiotics

An Introduction to Probiotics and Prebiotics

Probiotics and prebiotics both play important roles in supporting health and overall well‑being. Probiotics are live beneficial bacteria that improve gut health, while prebiotics are types of non-digestible dietary fiber that nourish these bacteria. Together, they maintain a balanced microbiome, which can enhance immunity, aid digestion, reduce inflammation, and improve mineral absorption.


Probiotics, the beneficial bacteria: Probiotics introduce good microorganisms into the digestive tract to fight harmful bacteria, manage inflammation, and improve bowel habits

Good Sources Include:
• Yogurt
• Sauerkraut
• Kimchi
• Kombucha
• Kefir (dairy & non‑dairy)
• Unpasteurized pickles
• Miso
• Tempeh
• Certain cheeses (cottage, Parmesan, cheddar, feta)
• Buttermilk


Prebiotics, the fuel source: Prebiotics are specialized plant fibers that cannot be digested, but stimulate the growth of beneficial bacteria already present in the gut.

Good Sources Include:
• Legumes
• Oats & whole grains
• Bananas
• Berries
• Apples
• Flaxseeds
• Jerusalem artichokes
• Asparagus
• Garlic
• Leeks
• Onions


Including both probiotics and prebiotics in your daily meals is a simple way to support gut health and overall well‑being. Focusing on a wide range of whole foods can help nourish beneficial bacteria and promote long‑term digestive balance.
