Ethical Skeptic posted this info awhile back:
1. Most probiotics contain the species on the left
2. Most people lost species on upper right after 1995
3. Species which replaced them have caused problems (bottom right)
Wish I had saved the actual link, and not just the data.
Wonder what happened in 1995?
Also wondering if the home made kefir (other ferments) contains the species on the right?
