What are probiotics?
Before we dive into prebiotics, it’s important to understand what probiotics are.
Probiotics are live, “good for you” bacteria.12 When consumed regularly and in the right amounts, these friendly bacteria populate your gut and can be beneficial to your overall health.12 Different probiotics can have different health benefits, ranging from immune properties to supporting your digestive health.2
Probiotics are not naturally found in foods, but some foods are made using live bacteria as part of their processing.12 Examples of these include yogurt, kefir, kimchi, sour pickles, kombucha, sauerkraut, sourdough bread, miso, and tempeh.1 Probiotics are sometimes added to yogurt or infant formula, and they are also available in the form of supplements.34

What are prebiotics?
Prebiotics, on the other hand, promote the growth and health of our friendly gut bacteria by acting as their food source.5 Generally, prebiotics are hard-to-digest fibers that are broken down by gut bacteria.5
Food sources include: onions, garlic, under-ripe bananas, oats, artichokes, asparagus, leeks, psyllium fiber, whole grain wheat, whole grain corn, and chicory.15
Prebiotics are in breastmilk
Breast milk provides more than just nutrition; digestive enzymes, immune factors and hormones are additional components of breastmilk.78 Research has also found that breastmilk contains both probiotics and prebiotics.7 Both of these components in human milk vary in amount between women, possibly due to dietary intake, as well as over the course of lactation due to changes in infant needs.8
Studies show that some prebiotics can be beneficial for infants by promoting the growth of healthy gut bacteria, supporting the immune system, and stimulating bowel movements and softer stools.910
Interestingly, babies’ gastrointestinal tracts in the womb are ‘sterile’ and do not have any bacteria.11 Once born, the infant is exposed to bacteria from the mother and environment. Diet then plays a crucial role in the development of beneficial gut bacteria. Babies who are formula fed tend to have different bacteria in their gut than those who are breastfed.11
Though it is not yet possible to exactly replicate the prebiotics found in human milk, research continues to illuminate the benefits of these compounds in early infancy.1011 For this reason, some infant formulas are beginning to include prebiotics in their formulations.11
At around six months, solid foods are introduced.12 During this time, additional changes occur to our baby’s gut bacteria.13 Including foods containing prebiotics, in a texture that your child can handle, can help support your baby’s gut health.14
