Kombucha has been drunk for centuries and contains many many beneficial microbes as well as other wonderful antioxidant, anti-inflammatory properties.

Kombucha is fermented tea - usually green or black. It requires a SCOBY. Get one from a friend or order one from a reputable supplier.

Kombucha is living and active and produces bubbles. So be careful to 'burp' your Kombucha regularly - say daily otherwise there is a real risk of explosion. 

In Phase II D2D remember to add foods gradually. Adding lots of fermented foods all at once can be lead to a Herxheimer ('die-off') reaction. This is where the microbes in the ferment compete with the microbes in the gut (usually the upper intestine) and cause the microbes in the gut to die, leaving inflammation, bloating and pain. By adding one new food per week, this is less likely to happen.
