So here is a very cool paper explaining a lot of things about
probiotics. Mainly the individual effects of single probiotics on inflammation. Answers a lot of questions - and perhaps explains why some have the strong adverse reactions to VSL3 and Fecal Transplants and why some have great results etc etc. And it provides a wonder explanation of the immune system etc.
Quite informative actually.
