Youri Zaritski was born in Russia and during his childhood he was consuming milk Kefir ( Russian: Кефир ) – this was the word to describe something that Youri thought to be Yogurt during his childhood. It is only later on that he has discovered how much more powerful Kefir is and what it really meant for human body and its balance and overall health.
It is really not the same. Both use the same principal of fermentation and providing friendly bacteria to the person consuming it. There is a major difference between Kefir and Yogurt. Kefir is at least 10 times more powerful and potent than Yogurt by having 40 types of friendly bacteria VS only 4 types of bacteria for the Yogurt). Kefir also contains 10 types of yeast that Yogurt doesn’t have.
There is also Water Kefir that uses more or less the same bacteria and yeasts as the milk version of it but do not work really in the same way. Milk Kefir is specialized more into digesting the fats in sugars present in the milk, while the water kefir is not really “ready for it”. The physical appearance and behavior of milk and water Kefir differ. So we do advise to drink both of them to insure a greater variety of natural defenses.
Our digestive system in optimal condition contains 400 species of bacteria and yeasts. Now, I go for Kefir rather then yogurt when my goal is to replenish my digestive system with the good bacterial environment.
