Research shows that a serving of kefir with more than 10 billion colony-forming-units of bacteria, can get bacteria all the way down the digestive system to the colon and change the landscape of the microbiome for the better (1).
For this reason, I advocate kefir in my gut diet protocol “The Gut Makeover”, and with clients in my private practice, because the numbers of bacteria are usually much higher with better chance of survival to the colon where it can help benefit the body (2, 3, 4) . It’s about gut colonisation, and for this I like to have the big guns, kefir!
