Kombucha

Black tea is fermented with bacteria, yeast, and sugar to create kombucha. A SCOBY, or symbiotic colony of bacteria and yeast, is produced during the fermentation process. Probiotics, acetic acid, and antioxidants are all present in kombucha after fermentation, and they may all have health advantages.

Studies on animals and in the lab reveal that kombucha may enhance blood sugar levels in diabetics, cholesterol levels, and the immune system. The reported health advantages in people, however, are mostly anecdotal. Since there is a significant chance that your homemade kombucha may be contaminated with dangerous microorganisms, it is not advised. There are several commercially available types, though, that doesn't carry the same amount of risk.
