Your gut is home to millions of micro-organisms that together form your gut microbiome. These micro-organisms, which can also be found in various types of food, are known as probiotics. Foods containing probiotics are referred to as probiotic foods. It is important to consume probiotics daily as they play a role in gut health. You can find probiotics in yoghurt, tempeh, kefir, and fermented foods like kombucha and kimchi. In addition to probiotics, there is often talk of prebiotics. Prebiotics are food for the bacteria in your gut, whereas probiotics are the bacteria themselves.
