Which foods have live active cultures?

Foods that usually containing live active cultures include buttermilk, yogurt, sauerkraut and miso. Cultured cottage cheese, kimchi, kombucha and kefir also contain live cultures.

Yogurt is the most common culture-containing food available. As long as the container contains the words "live" or "active," consumers know they are receiving a healthy dose of probiotics, live bacteria that helps the digestive system. Kefir is also gaining in popularity because of its probiotic characteristics. Kefir is similar to a yogurt, but it is thinner and often consumed as a drink that contains a different set of probiotics than yogurt.
