Foods rich in probiotics include buttermilk, cheese, miso, and tempeh. 1. Buttermilk: It is fermented by lactic acid bacteria, and probiotics are produced in the process. Buttermilk also provides calcium that the body needs. However, be aware that cooking buttermilk may kill the probiotics in it, so it is more suitable for direct consumption. 2. Cheese: Some cheeses are a good source of probiotics. Cheese is formed when lactobacilli make milk into cheese and then ferment it for days, weeks or even years, a process that also creates probiotics. 3. Miso: Miso is made from soybeans that have been set aside and fermented, a process that creates probiotics. 4. Tempeh: Tempeh is a soy product made from soybean paste, which produces probiotics during the process and is high in protein. There are many other foods that are rich in probiotics, and consuming probiotic-rich foods will benefit the health of the intestinal flora, but in moderation.
