It doesn't answer all the questions I have but I think it is rational. > Mounting evidence suggests that the richer and more diverse the community of microbes in your gut the lower your risk of disease. So this is the main law from science pertinent to the article. My impression is that many people are interested in this law today. > What we didn’t know is whether a healthy stable gut microbiome could be improved in just a few days. This is the empirical question that the experiment explores. If the article is honest, then the reader has some food for thought. Science would be better served with a better study.
