QUESTION: FREEZING AND HEATING PROBIOTICS
Can you freeze or heat probiotics or does this make them less effective? I was thinking of making kefir ice cream and also warming up sauerkraut or kimchi.

Sauerkrauts are best considered a live raw food. Raw sauerkraut can contain a mixture of over 13 different species of gut-friendly bacteria. Heating it would kill the microorganisms that have such a great probiotic effect.
Kefir ice cream, however would work. Lactobacillus bulgaricus and Streptococcus thermophilis as well as other live cultures such as L. acidophilus enter a dormant state during freezing, returning to an active state when they come in contact with body heat after ingestion.
I like the idea of Frozen Kefir treats. Yum!
