Probiotic是什么意思

"Probiotic" is a term used to describe live microorganisms, typically bacteria, that are beneficial to the health of the host organism. These beneficial bacteria are similar to those naturally found in the human gut and are often referred to as "good" or "friendly" bacteria. When consumed in adequate amounts, probiotics can help maintain the balance of microorganisms in the body and support overall health.

Probiotics are often found in fermented foods like yogurt, kefir, sauerkraut, kimchi, and miso, as well as in dietary supplements. They are believed to offer a range of health benefits, including improving digestion, enhancing the immune system, and reducing the risk of certain diseases. However, it's important to note that the effectiveness of probiotics can vary depending on the strain and the individual's health status.

The term "probiotic" comes from the Greek word "pro," meaning "for" or "in favor of," and "biotic," meaning "life." This distinguishes them from "prebiotics," which are non-digestible food ingredients that promote the growth of beneficial microorganisms already present in the gut, and "synbiotics," which are combinations of probiotics and prebiotics.
