Probiotic Toolkit


Written by: CDHF

Updated: February 21st, 2024

Probiotics, fibre and prebiotics can help support gut health. But what are they? We’ve gathered everything you need to know about digestive health, nutrition and probiotics in this toolkit.

Peruse through the full toolkit or jump to the information you are looking for by clicking below:

Nutrition, the Gut Microbiota and Immune Function

Good nutrition is important for proper gut microbiota and immune function. A healthy, balanced diet and lifestyle can support our immune system, whereas a poor diet can compromise the immune system, leading to greater susceptibility to infections.1,2 Having a diverse diet consisting of a variety of foods will provide your body with the nutrients it needs for a healthy immune system.

Probiotics vs Prebiotics

The World Health Organization (WHO) defines probiotics as “live microorganisms which when administered in adequate amounts confer a health benefit on the host.”3 In simple terms, probiotics are “good bugs” or “good microbes” that improve certain aspects of our health. 

Prebiotics are defined as “substrate that is selectively utilized by host microorganisms conferring a health benefit.”4 In other words, they are food for our gut microbiota.

Probiotics vs Fermented Foods

Fermented foods are foods or beverages that are produced by controlled microbial growth.5 They include things like yogurt, kefir, sauerkraut, and miso, to name a few!  

But did you know that not all fermented foods contain probiotics?

Dietary Fibre vs Prebiotics

Fibre describes plant material that your body cannot digest or absorb. Unlike fats, proteins or carbohydrates which your body breaks down and absorbs, fibres pass through and remain relatively intact through your stomach, small intestine and colon on its way out of your body. In other words, fibre binds with your body’s waste products, helping it move through the proper channels!  There are two types of fibre, soluble and insoluble, and both have different benefits for our health. 

The Connection Between Gut, Mood and Behaviour

Do you ever wonder why you sometimes experience “butterflies” in your stomach when doing something exciting, or have a “gut feeling” about a particular scenario? This is because our gut microbiota, i.e. the community of microorganisms living in the gut, does much more than just aid in digestion, immunity and metabolic functioning – it is a crucial connection to our brain and potentially our mood! Yes, the brain and the gut “talk” to each other – but maybe not in the way you think.

Functional Foods

Consuming “functional foods” has become a trendy approach that people consider when it comes to improving their diet and health. Did you know that probiotic foods can be considered functional foods because they provide health benefits beyond their traditional nutritional function?

Do all Fermented Foods contain Probiotics?

Even if they contain live cultures, very few fermented foods contain microbes that meet the definition of a probiotic. With the rising popularity of probiotics, you may be asking yourself how to include them in your diet. We are here to help you define the difference between the two with a simple side by side comparison.

What is Probiotic Yogurt and What are its Benefits?

Yogurt is a staple many people’s diet. It is a dairy product that is made by fermenting milk with a bacterial culture. When perusing the dairy section at the grocery store, you will see that are there are many types of yogurts, with each having different nutritional benefits. One of them is probiotic yogurt – a great gut-friendly food to include in your diet.
