Probiotics - Sauerkraut The sauerkraut in the store has been heated destroying the culture. Look up rejuvenative foods for sauerkraut made right - organic and aged only 5 or 6 days - I think you have to order 4 or 5 gallons to get a good price. I make my own. I like having the culture (food) that the probiotic grew on, instead of pills - sauerkraut is like prebiotic and probiotic. Most yogurt is not aged long so it is sweet and Sugar still is in it - that is why people make their own yogurt and kefir.
