@lioness, @fiesty, With regard to sauerkraut, I've just started on a Microbiome diet - eating fermented foods, I.e., sauerkraut, yogurt, cottage cheese, etc, and lots of fibre foods. My eldest son forwarded a medical research video on YouTube to me about how essential those foods are for a healthy gut. (Mine has been extremely unhealthy for many moons.)
My son has joined me in this, and is my coach! We make a good team, on long phone calls, since he lives in the Okanagan area of British Columbia, an eight hour trip away.
