I drink kefir that's full of good bacteria. I was always having stomach trouble and so somebody told me about natural sauerkraut. Then a doctor friend told me yogurt was really good for your gut. Next came the kefir pills that had 50 billion good bacteria and it helped more but cost $50 for a small bottle.
Finally, the wife got me some starter seeds and I been drinking homemade kefit every day.
Haven't had a major colon attack since.
However, there's always a drawback. This morning I discovered green mold coming out my rear end.
