ما هي البروبيوتيك؟

البروبيوتيك are live bacteria and yeasts found in your digestive system. The word probiotics is also used to describe foods or supplements which contain large amounts of these tiny living organisms.

Some popular probiotic health products often refer to these as the friendly bacteria or good bacteria. To scientists, these bacteria are known as microbes.

What do probiotics do?

Probiotics help to keep your gut healthy. The gut refers to your entire digestive system, from mouth to anus, also known as your digestive tract.

In your gut, you have thousands of different types of bacteria and other microorganisms. Scientists call this your gut microbiome. Probiotics are the bacteria that support important bodily functions and your overall health.

Every person has gut bacteria that can cause you harm if there are too many in comparison to probiotics. This imbalance is called gut dysbiosis, and it can be brought on by infectious disease, long-term use of bacteria-destroying medicines such as مضادات حيوية, or by following certain diets.¹

If this happens, you can increase the levels of probiotics in your gut by consuming probiotic foods or supplements. الميكروبيوم المعوي الخاص بك plays a key role in your immune system and many daily operations of the human body. So evidence suggests that addressing an imbalance of bad and good bacteria may help protect against several diseases and health issues.

What are the benefits of taking probiotics?

There is little evidence that taking probiotics through food or dietary supplements can benefit healthy people. Research even suggests that many people's gut microbiomes don't change when they consume probiotics, and that most actually pass right out of the body.

Yet, if you have an issue linked to your digestive health, probiotics may be worth trying.
