Prebiotics and probiotics – I cannot always remember which is which and I usually have to look it up when someone asks me a question about them. What I do know for sure is that they are important for a healthy gut microbiome. The gut microbiome is made up of the bacteria, viruses, fungi, and parasites that live in our digestive tract, mainly the colon. Having a healthy gut microbiome may have positive impacts on the rest of our body such as a stronger immune system, better absorption of some nutrients, and cardiovascular health.
Prebiotics are fibers that can’t be digested in the human body. They help probiotic bacteria grow and do their jobs inside our gut. You can get prebiotics by eating plant foods, including fruits, vegetables, beans, and whole grains.
Probiotics are live, active bacterial cultures that live inside our gut. Dairy foods such as yogurt, kefir, and cheese are good sources of probiotics. Be sure to read yogurt and kefir labels to find the words “live and active cultures”. Other fermented foods, such as sauerkraut, kimchi, and some soy foods, are also good sources of probiotics.
There are prebiotic and probiotic supplements sold in many stores. But before you buy these, please keep in mind:
- Supplements may be a higher dose than what your body needs, so always check with your healthcare provider before taking a new supplement.
- Supplements usually cost more than the food form of the nutrients.
- Supplements are not regulated in the same way food is, so do your research on different brands before you buy to find out if they are safe.
