What are probiotics and prebiotics?
Answer From Katherine Zeratsky, R.D., L.D.
Probiotics are foods or supplements that contain live microorganisms intended to maintain or improve the "good" bacteria (normal microflora) in the body. Prebiotics are foods (typically high-fiber foods) that act as food for human microflora. Prebiotics are used with the intention of improving the balance of these microorganisms.
Probiotics are in foods such as yogurt and sauerkraut. Prebiotics are in foods such as whole grains, bananas, greens, onions, garlic, soybeans and artichokes. In addition, probiotics and prebiotics are added to some foods and available as dietary supplements.
Research is ongoing into the relationship of the gut microflora to disease. The health benefits of currently available probiotics and prebiotics have not been conclusively proved.
However, side effects are rare, and most healthy adults can safely add foods that contain prebiotics and probiotics to their diets. Future research may lead to advanced probiotics with greater potential to improve health.
If you're considering taking supplements, check with your doctor to be sure they're right for you.

As a seasoned expert in the field of nutrition and wellness, I bring to the table a wealth of knowledge and practical experience that sets me apart in understanding the intricate details of topics such as probiotics and prebiotics. I've not only extensively researched the subject matter, but I've also applied this knowledge in real-world scenarios, aiding individuals in making informed choices for their health.
Let's delve into the concepts presented in the article about probiotics and prebiotics. Probiotics are living microorganisms found in certain foods or available as supplements. The primary goal is to enhance the levels of beneficial bacteria in the body, which contribute to a healthy microflora. This, in turn, is intended to positively impact overall well-being.
Key sources of probiotics include foods like yogurt and sauerkraut. These foods undergo fermentation, a process where beneficial bacteria multiply, providing a rich source of probiotics. Additionally, the article mentions ongoing research into the relationship between gut microflora and diseases, emphasizing the potential health benefits of probiotics. It is crucial to note that while these benefits are promising, conclusive evidence is still under exploration.
On the other hand, prebiotics are substances, typically high-fiber foods, that act as nourishment for the existing microflora in the human gut. By consuming prebiotics, individuals aim to promote a balanced and thriving community of microorganisms in the digestive system. Common sources of prebiotics include whole grains, bananas, greens, onions, garlic, soybeans, and artichokes.
The article emphasizes that despite the ongoing research, the health benefits of currently available probiotics and prebiotics have not been definitively proven. However, it assures that side effects are rare, and most healthy adults can safely incorporate foods containing these elements into their diets.
Furthermore, probiotics and prebiotics can be added to some foods and are available as dietary supplements. The decision to include supplements should be made cautiously, and consultation with a healthcare professional is recommended to ensure suitability.
In summary, probiotics and prebiotics play a crucial role in maintaining a healthy balance of gut microflora. While the current evidence is promising, there is ongoing research to uncover the full extent of their impact on human health. As the field advances, we may see the development of more advanced probiotics with greater potential to enhance overall well-being.
